Electroplating of copper
Electroplating is a process that uses an electric current to coat an electrode with metal by transferring metal ions in a solution onto the electrode. The document provides instructions for electroplating a copper coating onto a key using a copper sulfate solution, copper anode, and battery. When current is applied, copper ions in solution are oxidized from the anode and travel to the cathode/key, where they are reduced and deposited as a copper coating on the key's surface. Electroplating can coat many metal items like ornaments and coins.
Power point presentation based on electroplating
Electroplating is a process that uses electricity to coat an object with a thin layer of metal. It involves using a cathode, anode, electrolyte, and power source. The metal ions in the electrolyte solution are attracted to the cathode due to the electric current, reducing and plating the metal onto the cathode. Electroplating is widely used in industries like automotive, aerospace, electronics, and jewelry to protect objects from corrosion, improve appearance and surface properties, and reduce friction.
electroplating
Its Is The Process By Which A Iron Nail Is Been Coated With Copper Plate.Electroplating is a process that uses electrical current to reduce dissolved metal cations so that they form a coherent metal coating on an electrode. The term is also used for electrical oxidation of anions onto a solid substrate, as in the formation silver chloride on silver wire to make silver/silver-chloride electrodes. Electroplating is primarily used to change the surface properties of an object (e.g. abrasion and wear resistance, corrosion protection, lubricity, aesthetic qualities, etc.), but may also be used to build up thickness on undersized parts or to form objects by electroforming.
The process used in electroplating is called electrodeposition. It is analogous to a galvanic cell acting in reverse. The part to be plated is the cathode of the circuit. In one technique, the anode is made of the metal to be plated on the part. Both components are immersed in a solution called an electrolyte containing one or more dissolved metal salts as well as other ions that permit the flow of electricity. A power supply supplies a direct current to the anode, oxidizing the metal atoms that comprise it and allowing them to dissolve in the solution. At the cathode, the dissolved metal ions in the electrolyte solution are reduced at the interface between the solution and the cathode, such that they "plate out" onto the cathode. The rate at which the anode is dissolved is equal to the rate at which the cathode is plated, vis-a-vis the current flowing through the circuit. In this manner, the ions in the electrolyte bath are continuously replenished by the anode.[1]
Other electroplating processes may use a non-consumable anode such as lead or carbon. In these techniques, ions of the metal to be plated must be periodically replenished in the bath as they are drawn out of the solution.[2] The most common form of electroplating is used for creating coins such as pennies, which are small zinc plates covered in a layer of copper. [3]Process[edit]
Electroplating of a metal (Me) with copper in a copper sulfate bath
The cations associate with the anions in the solution. These cations are reduced at the cathode to deposit in the metallic, zero valence state. For example, in an acid solution, copper is oxidized at the anode to Cu2+ by losing two electrons. The Cu2+ associates with the anion SO42- in the solution to form copper sulfate. At the cathode, the Cu2+ is reduced to metallic copper by gaining two electrons. The result is the effective transfer of copper from the anode source to a plate covering the cathode.
The plating is most commonly a single metallic element, not an alloy. However, some alloys can be electrodeposited, notably brass and solder.
Nickel electroplating
Nickel electroplating provides benefits like increased corrosion resistance, improved hardness and strength, resistance to wear, and improved ductility. During nickel plating, nickel ions are reduced at the cathode through a reduction reaction, while the anode undergoes an oxidation reaction that dissolves metal. The thickness of a nickel plate coating is affected by applying direct current over time at a certain current density per unit area being plated.
Electrolysis and Electroplating
The document discusses electroplating, which involves using electrolysis to coat a thin layer of one metal onto another. It explains that electroplating can be used to protect against corrosion or improve appearance. It then provides details on the electroplating process, where the metal to be plated is the cathode and connects to the negative terminal, while the metal used for plating is the anode and connects to the positive terminal. Ions of the anode metal dissolve and deposit onto the cathode. Copper plating of other metals like copper is provided as an example.

Silicon Carbide
Silicon carbide (SiC) is a synthetic material that was first discovered in 1893. It is formed through heating carbon and silica in an Acheson graphite electric resistance furnace at temperatures between 1700-2500°C. The most common crystalline form is alpha-SiC. SiC has several desirable properties including high strength, hardness, thermal conductivity, and chemical inertness. Its applications include use in automotive parts, cutting tools, jewelry, and power electronics. Specifically, its wide bandgap and high operating temperature make it suitable for use in fast switching power devices such as Schottky diodes, MOSFETs, and IGBTs.
Metalplating Industry
The document discusses various metal plating processes. It describes electroplating as coating metal onto another surface using electricity, where metal ions dissolve from the anode and deposit on the cathode. Electroless plating uses chemical reactions without electricity to deposit metal alloys like nickel-phosphorus. Galvanization coats iron or steel with zinc to prevent rusting. Post-plating processes like rinsing remove chemical residues. The electroplating industry generates various solid, liquid, and gaseous wastes that must be properly managed to reduce environmental pollution.
Surface treatment plating process
Electroplating is a process where a metal coating is produced on a surface through the action of an electric current in an electrolyte solution. Key factors that influence the quality of electroplating include current density, cathode efficiency, agitation of the plating bath, bath composition/concentration, water quality, and presence of impurities. Hydrogen embrittlement can occur during electroplating and negatively impact the metal's fatigue and mechanical properties.

Electroplating
Electroplating is a process that uses electrical current to deposit metal ions from a solution onto an electrode. It allows precise control over deposition rate by adjusting current or voltage. Electroplating can be used to make nanostructures by depositing metal into a porous template, such as a polycarbonate filter or diblock copolymer. The amount deposited is directly proportional to the current over time. Electroplating is a simple way to make nanowires for applications such as data storage elements, where magnetic nanowires can store data through magnetization direction.

There are over 80 types of pure metals, and the most common are aluminum and iron. Metals are extracted from ores in rock or obtained through recycling old metal objects.
Recycling and pollution
Recycling helps reduce air pollution and greenhouse gas emissions which contributes to climate change. Proper recycling and reducing car, trash burning, and fireplace use can help lower air pollution. If plastic waste is not curbed, fish populations are at risk as many ingest plastic instead of food and can die with plastic in their stomachs, threatening fish in the seas.
Plastic pollution (1)
Plastic pollution in the ocean is a significant problem, with over 30 million bottles and cans thrown into the sea daily in Spain alone and over 1 million masks found in oceans this year. An organization called The Ocean Cleanup was founded in 2013 to develop extraction technologies to remove plastic already in the oceans and intercept more at rivers, having received over $31.5 million in donations to address this issue threatening wildlife such as the whale found with over 125 plastic items in its body.
Recycle
Plastic recycling is important to address as plastics are contaminating marine animals and most die of starvation with plastic filled stomachs. Plastics in the ocean fill the stomachs of marine animals so they can no longer eat and they starve to death. Increased plastic recycling efforts are needed to reduce plastic waste that ends up in oceans harming wildlife.

hematic appreciation test is a psychological assessment tool used to measure an individual's appreciation and understanding of specific themes or topics. This test helps to evaluate an individual's ability to connect different ideas and concepts within a given theme, as well as their overall comprehension and interpretation skills. The results of the test can provide valuable insights into an individual's cognitive abilities, creativity, and critical thinking skillsPhenomics assisted breeding in crop improvement
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.

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.

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).

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.
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.
