A fuel cell converts chemical energy from hydrogen and oxygen into electrical energy. It has an anode and cathode separated by an electrolyte coated with a catalyst. Hydrogen is pumped into the anode and oxygen into the cathode. The catalyst splits hydrogen molecules into protons and electrons at the anode. The protons pass through the electrolyte but electrons cannot, forcing them through an external circuit to power devices. The electrons and protons reunite with oxygen at the cathode to form water, with no waste produced.

This document discusses different types of dielectric materials and their applications. It begins by defining dielectrics as materials that can be polarized by an electric field but do not allow electric current to pass through. It then describes three main types of dielectric materials - solid, liquid, and gaseous. Examples are given for each type. The document focuses on applications of dielectrics in capacitors and transformers, explaining how different materials are used depending on their properties and the voltage/precision needs of the application. It concludes by listing several advantages of various dielectric materials.4 The Atom & Electronic Configuration

Guiyu, China has become known as the "electronic graveyard" due to the 150,000 workers who disassemble e-waste from other countries. Workers recover valuable metals by burning circuit boards and melting components with no environmental protections. This has caused severe pollution to the air, water, and soil that has led to high rates of cancer, miscarriages and birth defects among the local population. While the work provides income, the health risks have created a public health crisis due to the toxic methods used to recover materials from e-waste.Chemical bonding xi , dr.mona srivastava , founder masterchemclasses

Electrolysis is the decomposition of a substance by an electric current, where electrolytes carry current as ions in solution. During electrolysis, ions move to the electrodes and undergo oxidation or reduction reactions. At the cathode, electrons are gained and reduction occurs. At the anode, electrons are lost and oxidation occurs. The amount of substance deposited or gas produced can be calculated using Faraday's law, relating current, time, and moles of electrons in the electrode reactions.E-mobility | Part 2 - Battery Technology & Alternative Innovations (English)

Today, 60% of electric vehicles (EVs) are powered by lithium-ion batteries (LIBs) due to its efficiency, high power-to-weight ratio and flexibility to allow chemical alterations. As the EV industry gains steam, supply chain and design challenges are spurring battery manufacturers to explore alternatives.
Some of the alternative battery technologies include lithium-iron phosphate (LFP), lithium-sulfur battery (LSB) and sodium-ion battery (SIB). Besides LFP, LSB and SIB, solid-state batteries (SSBs) are touted as a forerunner for the next-generation battery technology.
Despite these advancements, the current speed of innovation is not accelerating fast enough to meet the demands of the rapidly growing EV sector. This presents opportunities in areas such as battery design and securing the supply chain locally via vertical integration.
As the world welcomes green mobility, commercializing battery technology will be imperative to drive global EV adoption. Given the increased push for battery development and innovation, we believe that it¡¯s only a matter of time before supply catches up with demand.

E-waste, or electronic waste, refers to discarded electrical or electronic devices. It is the world's fastest growing waste stream and poses environmental and health risks if not disposed of properly. The amount of e-waste in India is rapidly increasing as industries like IT and telecommunications grow and consumers replace electronics more frequently. Improper recycling of e-waste can release toxic chemicals like lead, beryllium, and mercury into the environment and harm workers who dismantle devices without protection.

It seems that with every new method, we invent to deliver products, whether physical or virtual, we reinvent productivity philosophies to go alongside them.

Regularly run repairs are essential to keep clusters healthy, yet having a good repair schedule is more challenging than it should be. Repairs often take a long time, preventing running them often. This has an impact on data consistency and also limits the usefulness of the new repair based tombstone garbage collection. We want to address these challenges by making repairs incremental and allowing for automatic repair scheduling, without relying on external tools.Formal Methods: Whence and Whither?

Formal Methods: Whence and Whither? [Martin Fr?nzle Festkolloquium, 2025]Jonathan Bowen
?
Alan Turing arguably wrote the first paper on formal methods 75 years ago. Since then, there have been claims and counterclaims about formal methods. Tool development has been slow but aided by Moore¡¯s Law with the increasing power of computers. Although formal methods are not widespread in practical usage at a heavyweight level, their influence as crept into software engineering practice to the extent that they are no longer necessarily called formal methods in their use. In addition, in areas where safety and security are important, with the increasing use of computers in such applications, formal methods are a viable way to improve the reliability of such software-based systems. Their use in hardware where a mistake can be very costly is also important. This talk explores the journey of formal methods to the present day and speculates on future directions.

- 2. How It WorksA fuel cell is a device that takes stored chemical energy and converts it to electrical energy.Needs two types of fuel.HydrogenOxygen
- 3. Parts of a Fuel CellAnodeCathodeElectrolyte + CatalystHydrogen GasOxygen
- 4. AnodeThis is the negatively charged side of the fuel cell.Oxygen is pumped into this sideCathodePositively charged side of the fuel cellHydrogen is pumped into this sideElectrolyteCoated with a catalyst.A catalyst is a substance that increases a chemical reaction.Separator/Bi-Polar plateUsed to collect the currentTo build the voltage
- 5. One O2 Molecule is supplied to the cathode which is then split by the catalyst into two oxygen atoms these two atoms both have a negative charge.One H2 Molecule us supplied to the anode which then is split by the catalyst into two hydrogen ions and two hydrogen electrons.The ions are attracted to the cathode because, it has negatively charged molecules. An the ions are able to pass through the electrolyte because, they are positively charged.How a current is made123
- 6. 4The electrons can¡¯t pass through the electrolyte because, they are negatively charged so they have to go through a different route this route goes out side of the fuel cell device. The flow of electrons through this other current can be used as electricity because a current is just a flow of electrons. So now we have a current that can be used to power something!Now they all combine in the cathode and become two H2O molecules (water).5
- 7. THIS IS SO COOL!!!!!The best part is that since you put in two hydrogen molecules and two oxygen molecules you got two H2O molecules back. This means there was not waste! At all! The same amount of water that you put in is the same amount that you get back! Now that¡¯s clean energy!
- 9. Negatively charged electrons can not go through the electrolyte so they have to go a separate route which creates a current because a current is just a flow of electrons which can then be used for electricity.Positively charged ion are being attracted by negatively charged O molecules.
