This document describes a new processing route for producing La9.33Si2Ge4O26 electrolytes for solid oxide fuel cells (SOFCs) that combines mechanical alloying and microwave hybrid sintering. The process involves milling raw materials (La2O3, SiO2, GeO2), pressing the milled powder into pellets, and sintering the pellets using microwave heating. This new process results in dense pellets with nanometer-sized grains and ionic conductivity values suitable for SOFC electrolytes while requiring lower sintering temperatures than conventional methods.
Crystal growth techniques
This document discusses and compares two techniques for growing single crystal silicon: the Bridgman technique and the Czochralski (CZ) technique. It states that while the Bridgman technique is simpler, involving a quartz ampoule, boat, heater and temperature profile, crystals grown with this method contain many dislocations. The CZ technique is more complex but can produce higher quality crystals. It involves controlling a furnace, crystal pulling rate, ambient conditions and system. The document concludes that the CZ technique is preferable for growing single crystal silicon due to producing crystals with fewer defects.

This document describes a method for dispersing particles in liquid metals using simultaneous electromagnetic and mechanical ultrasound. Key points:
- Electromagnetic fields are used to induce cavitation and acoustic streaming for particle dispersion, while mechanical ultrasound is injected via a probe for more localized mixing.
- Experiments showed this combined approach helped disperse micron-sized silicon carbide, titanium nitride, and yttria oxide particles more uniformly in molten metals like tin, aluminum, iron, and copper.
- Pulsed electromagnetic fields were also tested and shown to break oxide layers and induce strong stirring in molten tin, with potential for scaling up production of metal matrix composites.

This document discusses recrystallization in metals and methods to investigate the nucleation stage of recrystallization. It summarizes different techniques to induce or inhibit recrystallization including deformation, annealing, and rapid/ultrafast heating methods. Instrumented indentation and electron backscatter diffraction are identified as tools to characterize local microstructure changes during the initial nucleation events. Future work should focus on controlling nucleation sites and integrating experimental data on local misorientation into recrystallization models.
Fabrication of patterned ferromagnetic shape memory thin films
This document summarizes the fabrication of patterned ferromagnetic shape memory thin films. It discusses two routes for micropatterning Ni-Mn-Ga thin films using self-assembled polystyrene spheres and reactive ion etching. Route 1 uses a Si sacrificial layer deposited at 500°C, while Route 2 produces arrays of Ni-Mn-Ga antidots at room temperature followed by annealing at 500°C. Characterization shows the patterned films via Route 2 exhibit ferromagnetism up to 100°C and a spread martensitic transformation, demonstrating their functional properties. Route 1 showed promise but requires further optimization.
CrO2 – low temperature thin film growth, structural and physical properties
The document summarizes research on growing chromium dioxide (CrO2) thin films at low temperatures using chemical vapor deposition. Key findings include:
1) High quality CrO2 thin films with the desired structural and magnetic properties could be grown at as low as 330°C, significantly lower than previous methods allowed.
2) Films grown at lower temperatures had thinner intermediate chromium oxide layers and higher spin polarization near 100%, desirable for spintronic devices.
3) Growth temperature, oxygen flow rate, and film thickness were found to influence the structural, magnetic, and electrical properties of the resulting CrO2 thin films.

Fundamentals, synthesis and applications of Al2O3-ZrO2 composites
When the word “Ceramic” comes to our mind, we usually associate them with plates, saucers, cups and mugs. But, the word “Ceramic” encompasses more than just the word “plates” or “saucers”. Indeed, ceramic materials are hard and inherently brittle, but this is just the tip of the iceberg. They have multifarious properties and have acquired a status of high technical importance in the field of scientific research. Ceramics are the soul of the modern day’s structural applications owing to their high mechanical and thermal stability under different challenging conditions. They exhibit remarkable properties such as high hardness, high wear resistance, high corrosion resistance, high elastic modulus, high melting point and the ability to retain high strength at elevated temperatures. Alumina (Al2O3) is one such remarkable ceramic material known for its unique optical, mechanical and electrical properties. But the brittle nature of Al2O3 limits its use in certain engineering applications. Therefore, the strength of Al2O3 and Al2O3- based ceramics can be enhanced by tailoring the microstructural design through the application of strategic techniques that may involve secondary phase particle inclusion (such as Zirconia, ZrO2)

Effect of dilution on microstructure and hardness of a nickel-base hardfacing...RAMASUBBU VELAYUTHAM
1) The document examines the effect of dilution on the microstructure and hardness of a nickel-base hardfacing alloy deposited on an austenitic stainless steel substrate.
2) Electron probe microanalysis revealed considerable dilution of the hardfacing alloy by the substrate material within the first 2.5mm of the deposit, altering the chemistry, microstructure, and decreasing the hardness in this region.
3) Beyond 2.5mm from the interface, the hardness increases to levels comparable to the undiluted alloy as subsequent deposit layers approach, due to decreasing dilution effects farther from the substrate.Corrosion and Erosion
It includes, introduction of Erosion and corrosion and the problems arise from this and there possible solutions.
Smectites
The document discusses smectites, which are 2:1 phyllosilicate clay minerals. Key points:
- Smectites have an octahedral sheet between two tetrahedral sheets and can expand greatly by absorbing water between interlayer spaces.
- They form in weathering environments and their abundance and distribution affects the formation of décollement zones in subduction zones.
- Smectite to illite transformation may be linked to seismicity as it strengthens sediments.

Simon Fraser University researchers developed novel polymer membranes for fuel cells. They synthesized fluoropolymer-block-ionic and fluorous-ionic graft copolymers with different architectures. The membrane morphology, including ionic channel size and continuity, depended on polymer structure and affected properties like water uptake and proton conductivity. Fully sulfonated membranes showed continuous increases in proton conductivity with ion exchange capacity, while partially sulfonated membranes peaked at moderate capacities due to conductivity drops at high capacities. The graft structure allowed high capacities without dissolution, promising for low-humidity proton conductivity needed in fuel cells.

ultra fine grained steels
1) The document studies obtaining ultra fine grain sizes in plain C-Mn steels with 0.15-0.3% carbon through warm deformation processing.
2) Three new processing routes are developed involving heavy warm deformation at different temperatures followed by cooling or coiling to produce either pearlitic, bainitic ferrite 1, or bainitic ferrite 2 microstructures.
3) Lower deformation/coiling temperatures produce finer ferrite grains but more elongated aspect ratios, while pearlitic/bainitic ferrite grains are smaller and more equiaxed than pro-eutectoid ferrite grains.

This document discusses the effect of heating rate on the structural and optical properties of silicon and magnesium co-doped zirconia nanopowders prepared by a sol-gel method. X-ray diffraction analysis showed that different heating rates between 1-10°C/min affected the formation of tetragonal and cubic phases, crystallinity, and particle size. Ultraviolet-visible spectroscopy showed that the band gap energy of the doped zirconia crystals decreased depending on the heating rate, with a minimum band gap of around 3-3.2 eV.

As the Reflection of Sunlight, falling on the solar cells is an big issue for its performance, this presentation deals with some Morphologies, mostly used these days in industries and some others also which was in trend years before, for c-Si cells.
The objective is to find out the most appropriate technology for Surface texturing either with or without AR coating that can reduce reflection to its minimum possible value.
Although, it is understood that, with best technology, cost also increases. Therefore, it is a quite challenging task at the present time to provide a cost effective surface Morphologies to limit the Panel cost to not to rise much.

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).

https://www.etran.rs/2024/en/home-english/Describing 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.
EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.
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.
Equivariant neural networks and representation theory
Or: Beyond linear.
Abstract: Equivariant neural networks are neural networks that incorporate symmetries. The nonlinear activation functions in these networks result in interesting nonlinear equivariant maps between simple representations, and motivate the key player of this talk: piecewise linear representation theory.

The debris of the ‘last major merger’ is dynamically young
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.
Immersive Learning That Works: Research Grounding and Paths Forward
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.
Authoring a personal GPT for your research and practice: How we created the Q...
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.
