This document provides an overview of electrochemistry and electrochemical cells. It defines electrochemistry as the branch of chemistry dealing with the relationship between electrical energy and chemical change. An electrochemical cell is a device that uses a chemical change to produce electricity or uses electricity to produce a chemical change. The document describes the components of electrochemical cells, including electrodes and electrolytes. It distinguishes between galvanic cells, which produce electricity from chemical reactions, and electrolytic cells, which use electricity to drive chemical reactions. Examples of the significance of electrochemistry include metal refining and batteries.Fuel cell

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.Hydrogen & fuel cells(by Abdul Ahad Noohani)

The document summarizes the key design considerations for hydrogen fuel cells. It describes how William Grove first demonstrated a fuel cell in 1839 by reversing the electrolysis of water into hydrogen and oxygen to generate a current. The basic operation of a hydrogen fuel cell involves hydrogen ions passing through a proton exchange membrane to the cathode where they combine with oxygen and electrons to form water, producing electricity. Connecting multiple fuel cells in series into a stack increases the overall voltage output, which is achieved through the use of bipolar plates that connect the anode of one cell to the cathode of the next. Proper gas flow and cooling design are also important considerations.Ele ctrode potential, electrochemical series

Dr. K. Rajender Reddy gave a lecture on electrochemistry that covered several topics:
1) Electrode potential is the tendency of a metal to lose or gain electrons when in contact with a solution of its own salt. Zn undergoes oxidation in ZnSO4 by releasing electrons, while Cu undergoes reduction in CuSO4 as copper ions are deposited.
2) The standard electrode potential is measured at 25属C with a 1M electrolyte concentration and represents the potential of an oxidation or reduction reaction.
3) The electrochemical series arranges electrodes in order of increasing standard reduction potentials, ranging from the strongest reducing agent Li to the strongest oxidizing agent F.The chemistry of batteries

Batteries are packages containing one or more galvanic cells that store electrical energy through chemical reactions. A battery contains two half cells, one for oxidation and one for reduction, separated by an electrolyte. When a circuit connects the battery terminals, a redox reaction occurs where the anode undergoes oxidation by releasing electrons and the cathode undergoes reduction by gaining electrons, generating a flow of electricity. The electrolyte facilitates the movement of ions between the half cells to complete the circuit.PEM Water Electrolysis

This document summarizes proton exchange membrane water electrolysis. It discusses how water electrolysis produces hydrogen and oxygen gas through an electric energy input that splits water molecules. A proton exchange membrane electrolyzer uses bipolar plates, gas diffusion layers, a membrane electrode assembly, and electrocatalysts. The membrane allows for hydronium ion transport without electron conduction.

This document discusses electrochemical cells. It defines an electrochemical cell as a device that can generate electrical energy from chemical reactions or use electrical energy to drive chemical reactions. There are two main types of electrochemical cells: galvanic/voltaic cells which convert chemical energy to electrical energy, and electrolytic cells which convert electrical energy to chemical energy.
A galvanic cell consists of two half-cells with different metal electrodes immersed in electrolyte solutions, connected by a salt bridge or porous membrane. Chemical reactions at the electrodes produce a spontaneous flow of electrons through an external circuit. For example, in a Daniell cell zinc undergoes oxidation and copper undergoes reduction. The overall cell reaction is Zn + CuBasic Fundamentals of Fuel Cells

A fuel cell converts chemical energy from a fuel into electricity through a reaction with oxygen or another oxidizing agent. Hydrogen is commonly used as a fuel but other fuels like natural gas can also be used. Fuel cells provide continuous power as long as fuel is supplied, unlike batteries which have a limited storage capacity. They produce water, heat, and small amounts of pollution as byproducts. Individual fuel cells produce low voltages so they are stacked to increase output. Fuel cells have efficiencies between 40-85% and are used in various applications including transportation, backup power, and utilities.Fuel cells

Fuel cells convert chemical energy from hydrogen into electrical energy through electrochemical reactions. A fuel cell has an anode, cathode, electrolyte, and catalyst. Hydrogen enters the anode and splits into protons and electrons. The protons pass through the electrolyte while the electrons power an external circuit. At the cathode, oxygen and the protons react to form water. Fuel cells have advantages like zero emissions and high efficiency but also disadvantages like high costs. Applications include portable power, transportation, and power distribution.Power engg.

Fuel cells convert the chemicals hydrogen and oxygen into water and produce electricity through this chemical reaction. They work by using hydrogen and oxygen as fuels that produce an electrical current between an anode and cathode separated by an electrolyte. This creates an electric current and provides energy, with the only byproduct being water. Fuel cells could significantly reduce pollution if used in automobiles, as the only waste produced is water that can help cool the engine.Recently uploaded (20)

SILICON IS AN INHIBITOR OF CERTAIN ENZYMES IN VITROLilya BOUCELHA
油
Silicon is considered an inorganic biostimulant and a prophylactic extracellular agent that allows the stimulation of a
wide range of natural defences against abiotic and biotic stresses. However, little or no work has focused on the direct action of silicon on some enzymes. Indeed, during this study, the action of silicon was studied in vitro by direct contact of this element at different doses with the enzymatic extracts of Trigonella foenum-graecum L. (fenugreek) seeds. Our results showed that silicon
strongly inhibited antioxidant and hydrolytic enzymatic activities. The percentage of this inhibition depends on the dose of silicon and the type of enzyme. The most sensitive enzymes to this inhibition were SOD and lipases whose activity was totally inhibited at
4 mM and 7 mM respectively. However, we report that the inhibitory action of silicon was limited to 50% for GPOX whatever the concentration of silicon used, the plateau being reached at 10 mM for GPOX and at 70 mM for proteases. Since these enzymes are mainly metallo-dependent, we hypothesize that their inhibition by silicon may be due to interactions between silicon and the metals involved in the functioning of each enzyme. Our study shows that silicon can be used as an inhibitor of enzymes involved in certain diseases.TOP 10 CBSE Top Science Projects for Classes 6 to 10 with Youtube Tutorial

Cell division is a fundamental biological process that enables the growth, development, and repair of living organisms. It's the process by which a parent cell divides into two or more daughter cells, each carrying a complete set of genetic instructions. This intricate process occurs in two primary ways: mitosis and meiosis. Mitosis is responsible for the creation of identical daughter cells, ensuring the maintenance of genetic information for growth and tissue repair. Meiosis, on the other hand, is a specialized form of cell division that occurs in sexually reproducing organisms, producing gametes (sperm and egg cells) with half the number of chromosomes, contributing to genetic diversity in offspring.Units and measurements includes definition and fundamental quantities.pptx

Scientific Pig Farming Manual for Pig Farmers
Scientific Pig Farming Manual for Pig FarmersDr. Subhrajit Das
油
Pig farming, pork farming, pig production or hog farming is the raising and breeding of domestic pigs as livestock, and is a branch of animal husbandry. Pigs are farmed principally for food (e.g. pork: bacon, ham, gammon) and skins.
Pigs are amenable to many different styles of farming: intensive commercial units, commercial free range enterprises, or extensive farming (being allowed to wander around a village, town or city, or tethered in a simple shelter or kept in a pen outside the owner's house). Historically, farm pigs were kept in small numbers and were closely associated with the residence of the owner, or in the same village or town.[1] They were valued as a source of meat and fat, and for their ability to convert inedible food into meat and manure, and were often fed household food waste when kept on a homestead.[2] Pigs have been farmed to dispose of municipal garbage on a large scale.[3]
All these forms of pig farm are in use today, though intensive farms are by far the most popular, due to their potential to raise a large amount of pigs in a very cost-efficient manner.[4] In developed nations, commercial farms house thousands of pigs in climate-controlled buildings.[5] Pigs are a popular form of livestock, with more than one billion pigs butchered each year worldwide, 100 million in the United States. The majority of pigs are used for human food, but also supply skin, fat and other materials for use in clothing, ingredients for processed foods,[6] cosmetics,[7] and medical use.[8]Pig farming has gained importance today. Pigs have inherited capacity to acclimatize with varying climatic conditions. Pigs cannot withstand high temperature climate.
Pigs are adjusted to varied rearing practices and consume different types of food (Omnivorous) to attain higher growth and meat production.
Pigs will attain 60-70kg body weight in 6-8months period.
Female pigs i.e., sows will come to heat at age of 8-9 months but avoid using male pigs (Boars) for breeding purpose until it attains one year of age.
Adult sows when bred during right time after attaining maturity will farrow 8-12 piglets in 112-118 days of gestation period (i.e., about 4 months of gestation). Feedefficiencyis to gain one Kg live weightfor every 2.75-3kg feed consumed (FCR: 1:2.75). There are many advantageous in pig rearing. Pork is available at a cheaper price with nutritious and highly palatable tasty meat of higher quality animal protein. Pig bones are used for producing bone meal and also used for purification of sugar in sugar industry.
The manure droppings and urine are good fertilizers which enhance the soil fertilityand improve grain production.
Pig hairs (Bristles) are used for making brushes and ropes, hooves are used for shirt button making and preparation of gum. Hence, pigs are called as multi utility domestic animals. Farmers can take up piggery farming and reduce their debt burden and improve their profits and livelihood.

- 2. What is Fuel Cell? Fuel cell is a device that converts chemical energy from a fuel into electricity through a chemical reaction with oxygen or another oxidizing agent
- 3. Parts of Fuel Cells There are four main part of Fuel Cells 1. Anode 2. Cathode 3. Electrolyte 4. Catalyst
- 4. Anode Anode is negative electrode of Fuel Cell. In most fuel cells, hydrogen is used as the negative electrode in pure form or impure hydrogen is taken as obtained from hydrocarbon fuel, such as natural gas, liquefied petroleum gas.
- 5. Cathode Cathode is positive electrode of cell. It conducts the electrons back from the external circuit to the catalyst, where they can recombined with the hydrogen ions and oxygen to form water.
- 6. Catalyst To speed up the chemical reaction, a catalyst is included in the electrodes. The best catalyst are finally divided platinum or other platinum like metal deposited on or incorporated porous electrode material.
- 7. Diagram of normal Fuel cell
- 8. Working of Fuel cells Basically, two principal chemical reactions occur at the interface of the three segments. The net result of the two reactions is that , when fuel is consumed, water is formed and an electric current is produced which can be use to power electrical devices, normally referred to as the load.
- 9. At the anode, a catalyst oxidize the hydrogen fuel into positively charged ion and negatively charged electron. The electrolyte(KOH) allows the protons to travel to the cathode but blocks the electrons. Thus, the electrons travel through the wire creating the electric current, The ions on reaching the cathode reunite with the electrons, and the two reacts with a third chemical, oxygen, to create water.
- 10. H2O2 Fuel Cell Hydrogen peroxide(HO) is commonly used as an oxidizer in rocket. Propulsion and air independent power system. In H2O2 fuel cells, nickel and silver are used as catalyst for hydrogen and oxygen respectively. When used to produce energy, hydrogen peroxide creates only pure water and oxygen as a by product, so it is considered as clean energy, like hydrogen. However, unlike hydrogen, H2O2 exists in liquid form at room temperature, so it can be easily stored and transported.
