Industrial Perspectives on Large-Area TCOs
TCOs (transparent conducting oxides) are used in a variety of applications and are deposited on large areas through various techniques. They are used in windows to improve thermal efficiency (U value) and in thin-film solar panels as front contacts. TCO characteristics like transmission, resistance, and morphology are important for different applications. Industrial TCO production involves either inline CVD coating of tin oxide during the float glass process or offline coating methods like magnetron sputtering at a later stage. Maintaining optimal optical and electrical properties while enabling large-scale manufacturing is key.

SiOx Nanoparticals.PDF
This document summarizes research on the synthesis of amorphous silicon oxide (SiOx) nanospheres using thermal evaporation of silicon monoxide (SiO). Structural analysis using electron microscopy and spectroscopy revealed that the nanospheres were uniformly spherical and amorphous in structure, composed solely of silicon and oxygen. Photoluminescence measurements showed strong blue emission from the SiOx nanospheres. A vapor-solid growth mechanism is proposed where SiO vapors react with oxygen to form SiOx vapors which then condense and aggregate to form the amorphous nanospheres on substrate surfaces in the temperature zone of 1100-1150°C.
Presentation of Johan Swahn in Greenpeace Nuclear Waste Seminar, Helsinki 2009
Johan Swahn, PhD, is the head of the Swedish NGO Office for Nuclear Waste Review, MKG.
The ongoing projects to establish a permanent disposal site for high level nuclear waste in Finland and Sweden have run into severe problems as science has progressed. The plan is to pack the waste in copper canisters that have recently been shown to be prone to failure already during the first thousands or even hundreds of years. The intention is to surround the waste with bentonite clay, the behavior of which over the course of centuries is also a question mark.
Topological Insulator Thin Films: Growth and Characterisation
This document summarizes research on growing and characterizing thin films of topological insulators. Molecular beam epitaxy was used to deposit films of Bi-Te-Cu(110) and α-Sn-InSb(111)A. Characterization techniques included LEED, AES, STM, and XPS. For Bi-Te-Cu(110), Te did not stick to the substrate and Bi growth was very slow. α-Sn formed islands on InSb(111)A but conditions to form an ordered monolayer were not achieved. Future work involves improving Bi growth conditions and repeating Sn deposition with variations in substrate, temperature, and other materials.

Authors: Zhimao Ni, Fa He, Kexin Liu and Qingrong Feng
MgB2, due to its high transition temperature of ~40K and absence of weak links between grains, is a candidate material for superconducting radio-frequency (RF) cavities for future particle accelerators. Peking University has developed a HPCVD method for MgB2 fabricating on metallic substrates. We have grown MgB2 films on the substrates of Cu, Nb and Mo[1] successfully. Recently, for better quality of MgB2 film, we tried to fabricate MgB2 film on Cu substrate which was coated a thin film of Mo on the surface. We also tried to obtain the large-area MgB2 film (2-inches in diameter) on metallic substrate with good uniform for RF measurement. The method and results of recent experiments will be presented.

M.S.ThesisDefense
This thesis examines using electrophoretic deposition (EPD) to coat 3D graphite felt with cobalt ferrite nanoparticles. The objectives are to improve the kinetically slow anodic reaction in the solar sulfur-ammonia thermochemical cycle for hydrogen production. Experiments include EPD with different suspensions, adhesion testing of deposits, penetration analysis via SEM, and electrochemical studies. Results show EPD fully penetrates the felt and maximum monolayer coverage is achieved. Deposits on 3 mm felt have the highest current density increase compared to the blank substrate.

An investigation was conducted into high failure rates of braze welds on an oil lance. X-ray investigation showed little wetting and penetration of the braze material. Analysis using an electron microprobe found the braze ring material composition was the specified 82% gold and 18% nickel. It was determined the likely cause was the groove size was too large for the specified amount of braze filler material.
Presentation project6
This document discusses semiconductor doping techniques used in the electronics industry. It describes intrinsic and extrinsic semiconductors and the two main types of doping: n-type and p-type. The two major doping techniques discussed are diffusion and ion implantation. Diffusion involves moving dopant atoms into the semiconductor through heating, while ion implantation accelerates dopant ions to implant them into the surface. Both techniques have advantages and disadvantages, with diffusion causing less damage but having less control over depth and concentration. Ion implantation offers more precise control but requires annealing to repair surface damage.
Final Project Plasma
The document summarizes a student's final project to design and construct a low pressure capacitively coupled plasma etcher. Key points:

- The initial design was simplified using aluminum and graphite electrodes. The final design maintained the materials due to cost but added insulation on the electrodes.
- Construction involved machining parts and assembling the chamber, which was then tested and optimized by addressing leaks and plasma instability issues.
- Diagnostics using optical emission spectroscopy were planned to analyze the plasma properties and etch species.
- Future work proposed improving the design and experimenting with
P si
This document provides an overview and review of research into light emission from porous silicon. It discusses how porous silicon exhibits strong photoluminescence with emission spectra that can be tuned from near-infrared to visible wavelengths by varying porosity. While the fundamental mechanisms of light emission are still being resolved, the four most commonly held views are that emission results from quantum confinement, surface molecular species, radiative decay at surface/interface states, or hydrogenated amorphous silicon produced during etching. The review aims to connect evidence from electrochemistry, surface science, microscopy and spectroscopy to further understanding of this complex material.

UMKC - Perovskite Solar Cells
The document discusses perovskite solar cells (PSCs) and highlights a new hole transport layer (HTL) material invented at the University of Missouri-Kansas City that could improve PSCs. Current PSCs use expensive and unstable HTL materials like spiro-OMeTAD. The new UMKC HTL material is inexpensive, transports charge fast, forms uniform dense films, provides good moisture barrier, and allows PSCs with significantly higher efficiencies and improved stability compared to spiro-OMeTAD. A provisional patent has been filed and further development is needed to fabricate PSCs in a clean room and demonstrate record efficiencies and stability under various conditions.
Hot wire Anemometer: microfabrication
The document discusses the fabrication process for micromachined hot wire anemometers. It involves depositing platinum or titanium wires on a silicon substrate using evaporation or sputtering. Contact pads and prongs are patterned using lithography and dry etching. The wires are released by vapor phase HF etching of the sacrificial silicon dioxide layer. Challenges include stress in evaporated platinum wires which can cause breakage at low temperatures. Sputtered titanium and wire design modifications help address this issue. The probes are tested inside a cryogenic probe station to calibrate their response to fluid flow.

Brandon Hart developed II-VI All-Inorganic Colloidal Quantum Dot Light Emitting Devices for digital displays. Quantum dot light emitting diodes (QLEDs) offer benefits like high color quality and efficiency but face issues with inefficient carrier injection into the quantum dots. Hart synthesized cadmium selenide/zinc sulfide quantum dots and applied them as the emissive layer between layers of nickel oxide and zinc oxide on an indium tin oxide substrate. When a current was applied, the quantum dot layer emitted bright green light at 520 nm. The new carrier injection method showed improved results over previous methods. Future research areas for quantum dots include quantum computing, cell staining, photovoltaics, and lighting.

The Use of Nanostructured Silicon in Photovoltaics
This document summarizes a student's master's thesis project on using nanostructured silicon to improve photovoltaic efficiency. The student aimed to reduce the size of silicon nanoparticles to exploit quantum confinement effects, deposit the nanoparticles onto an existing solar cell, and test the cell's performance. While the student was unable to achieve quantum confinement, nanoparticle size was reduced. However, coating the cell reduced its performance by blocking some light. Overall, the project established methods for future work to optimize nanoparticle production and integration into solar cells.
Deposition of Tin Oxide Nanoparticles for Electrochemical Studies of Amyloid ...
Film depositions of tin oxide nanoparticles were performed using DC magnetron sputtering on silicon and carbon glass substrates. Nanoparticles on silicon were too large and unevenly dispersed due to high temperature and exposure time, while carbon glass produced more rounded and evenly distributed nanoparticles when exposure time was increased to 10 seconds at 150°C. However, further adjustments are needed to eliminate gaps between nanoparticles and optimize the sample for testing amyloid peptides using cyclic voltammetry.

Deep Software Variability and Frictionless Reproducibility
Deep Software Variability and Frictionless ReproducibilityUniversity of Rennes, INSA Rennes, Inria/IRISA, CNRS
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.

Presented at June 6-7 Texas Alliance of Groundwater Districts Business MeetingDescribing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.

Unlocking the mysteries of reproduction: Exploring fecundity and gonadosomati...
The pygmy halfbeak Dermogenys colletei, is known for its viviparous nature, this presents an intriguing case of relatively low fecundity, raising questions about potential compensatory reproductive strategies employed by this species. Our study delves into the examination of fecundity and the Gonadosomatic Index (GSI) in the Pygmy Halfbeak, D. colletei (Meisner, 2001), an intriguing viviparous fish indigenous to Sarawak, Borneo. We hypothesize that the Pygmy halfbeak, D. colletei, may exhibit unique reproductive adaptations to offset its low fecundity, thus enhancing its survival and fitness. To address this, we conducted a comprehensive study utilizing 28 mature female specimens of D. colletei, carefully measuring fecundity and GSI to shed light on the reproductive adaptations of this species. Our findings reveal that D. colletei indeed exhibits low fecundity, with a mean of 16.76 ± 2.01, and a mean GSI of 12.83 ± 1.27, providing crucial insights into the reproductive mechanisms at play in this species. These results underscore the existence of unique reproductive strategies in D. colletei, enabling its adaptation and persistence in Borneo's diverse aquatic ecosystems, and call for further ecological research to elucidate these mechanisms. This study lends to a better understanding of viviparous fish in Borneo and contributes to the broader field of aquatic ecology, enhancing our knowledge of species adaptations to unique ecological challenges.
The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptx
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).
ESR spectroscopy in liquid food and beverages.pptx
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.

- 5. • Electrochemical detection of β-amyloid peptides on electrode covered with N-terminus-specific antibody based on electrocatalytic O2 reduction by Aβ(1-16)-heme- modified gold nanoparticles (Liu, et al. 2013). • Aβ(1-16)-heme-AuNPs detected Aβ testing it with cyclic voltammetry. • About 10 pM ofAβ was the detection limit of the Aβ(1-16)-heme- AuNPs . • Its results are comparable with the Surface Plasmon Resonance (incidence of light on electrons of the substrate).
- 6. • Problem: • Does the sputtering procedure helps to spread a film ofTin oxide nanoparticles over a Silicium substrate and a Carbon glass substrate? • Hypothesis • The sputtering procedure will deposit theTin nanoparticles forming a film over an exposed area of the Silicium substrate and on the Carbon glass substrate.
- 7. Objectives: • Demonstrate that the sputtering technique is an alternative for the development of thin film formations. • Compare the final products in Silicium and Carbon glass substrates for differences. • Help improve the affinity ofTin Oxide towards Amyloid Peptides by studying sputtering. http://www.intechopen.com/source/html/10517/media/image1.jpg
- 9. Procedure (Magnetron Sputtering) Substrate (Anode) Target (Cathode) Argon Plasma (Ar+, Ar, e-, hυ) Ar Ion Sputtered particle 4. Electrons released during Argon ionization are accelerated to the substrate, subsequently colliding with additionalArgon atoms, creating more ions and free electrons in the process, continuing the cycle. 1. Electrically neutralArgon atoms are introduced into a vacuum chamber. 2. DC (direct current) voltage is placed between the target and substrate which ionizes Argon atoms and creates a plasma (glow discharge) 3. These Argon ions accelerate to the target. Their collision with the target ejects target atoms, which travel to the substrate and eventually settle. Ionized Argon bombards a target, releasing atoms which form layers on a substrate. http://www.pfonline.com/articles/vacuum-deposition-processes • Physical process • In a vacuum chamber, gas pressure is less than the ambient atmospheric pressure.
- 10. First Result • Si substrate • 1 min. • 50W • 160 ºC • Bigger spheres due to high temperature and long period of exposure
- 11. Second Result • SiOx substrate • 20 s • 50W • Room temperature (21-23ºC) • Uneven nanoparticles because of low temperature.
- 12. Third Result • Carbon glass substrate • 10 s • 50W • 150 ºC • Circular shaped nanoparticles because of balanced adjustments of temperature and time exposure
- 13. Results in Comparison • Si substrate • 1 min. • 50W • 160 ºC • SiOx substrate • 20 s • 50W • Room temperature (21-23ºC) • Carbon glass substrate • 10 s • 50W • 150 ºC
- 14. Conclusions • The sputtering system is a versatile technique for depositing any solid material • This procedure assures the deposition ofTin nanoparticles film over the exposed area of the Silicium substrate. • Although the tested carbon glass substrate did not result as figured, it was understood that the error was due to maladjustments on temperature and time exposure.
- 15. Future Research • Repeat the sputtering process on another glass Carbon substrate using another adjustments on temperature and exposure time. • After obtaining a potential pure substrate product with theTin oxide nanoparticle layer: • The product would be sent to Dr.Ana Guadalupes’ group at UPR-Río Piedras for the testing part using Amyloid peptides. • The electrochemical properties of the Amyloid peptides are studied doing cyclic voltammetry in relation to theTin oxide nanoparticles and a Ferrocene connector.
