Probably we all know the dark side of nuclear energy. In reality, the bright side of it exceeds the dark side in many folds. In this article we will learn about nuclear detectors, their types and different constituents of nuclear reactors. What is a nuclear reactor? A nuclear reactor is a device that is designed […]

While the radiation propagates out from the nucleus, it interacts with other matter along its path. These interactions with external matter allow us to observe the radiation, and its effects, and to determine the nature of the transition inside the nucleus. This interaction of radiation with matter is also the cause of chemical, physical, and

What is Radioactive Decay? Radioactive decay is a spontaneous nuclear transformation that has been shown to be unaffected by pressure, temperature, chemical form, etc (except a few very special cases). Radioactive decay involves a transition from a definite quantum state of the original nuclide to a definite quantum state of the product nuclide. Example of

Special Nuclear Reactions 1. Neutron Induced Fission 2. Fusion 3. Photonuclear Reactions 4. Heavy Ion Reactions Neutron Induced Fission • A neutron is captured by heavy nuclide to form a compound nucleus • Compound nucleus then splits into two smaller fragments and emits two or three free neutrons along with 200 MeV of energy •

Models for nulear reactions: No single reaction mechanism or model can explain all features of different types of nuclear reactions. Three well-known proposed mechanism of nuclear reactions are- 1. The optical model 2. Liquid-drop model or compound nucleus model 3. Direct interaction model The Optical Model of Nuclear Reaction This model uses the principle of

Define Nuclear Reaction Reactions between an atomic nucleus and another particle are called nuclear reactions. A typical nuclear reaction involves two reacting particles—a heavy target nucleus and a light bombarding particle—and produces two new particles— heavier product nucleus and lighter ejected particle.

Any unwanted or discarded material that are detrimental for environmental can be termed as solid waste. Solid waste management covers the control of solid waste generation, collection, storage, transport, processing, separation, recycling, recovery and purposeful disposal of solid waste. Usually, solid wastes management is handled by a municipal, city or town authorities. Major considerations of

Our earth’s ecosystem has four components. The atmosphere is one of them. The other three components are the biosphere, hydrosphere, and lithosphere. The atmosphere is the gaseous band that surrounds our earth’s surface. It’s the gravity of the earth that protects the atmosphere from being disappeared into outer space. Availability of gases in the atmosphere

Yes. There are several chemical reactions that take place during the heating of the milk. Heat induced chemical reactions of milk can be classified into five groups: Acid development Precipitation of calcium phosphate Maillard reactions Casein modification and Interaction of sulphydryl groups In fresh milk all the ingredients remain in a large number of equilibria
Is the heating of milk a chemical process? Read More »
You can heat fresh milk at 140 °C around 10 min. If you keep heating coagulation will occurs. It happens due to the aggregation of the milk proteins. Milk contains 85-88 % of water depending on the source animal and rest of them are solids. Usually cow’s milk solid contains lactose (4.9%), fat (3.4%), protein
