The Building Blocks of Life: Macronutrients Essential for Plant Growth Plants, the foundation of our ecosystems and food systems, are remarkable organisms capable of converting sunlight into energy through photosynthesis. This process, however, requires a complex interplay of various elements, including those we call macronutrients. These essential nutrients, absorbed from the soil and air, play … Read more
Harnessing the Sun’s Power: A Deep Dive into Concentrated Solar Power The world is facing a pressing need to transition away from fossil fuels and embrace renewable energy sources. Among the many promising options, Concentrated Solar Power (CSP) stands out as a technology with the potential to play a significant role in meeting our energy … Read more
Quick revision Topic: Corrosion and its prevention Definition: It is the process in which metals are slowly eaten up by the action of air moisture or chemicals. For example rusting is a form of corrosion in which iron is eaten up by the action of air and moisture and a reddish brown coating of iron oxide is formed … Read more
Development of non-conventional sources of energy is of prime importance for the sustainable and Energy Resources are depleting at an accelerated rate and non-conventional resources could play a leading role in Energy Security in the state. Non-Conventional energy resources could minimise the transmission cost and energy divide between the remote locations [su_heading size=”21″]Solar[/su_heading] Rajasthan … Read more
Chemical Bonding and Molecular Structure The smallest particle of element is atom and the smallest particle in a compound is molecule. The force or the binding that keeps the atoms in the molecule combined during the formation of molecule is called chemical bonding. The concepts like that of Kossel-Lewis, VSEPR principle, valence bond theory, molecular … Read more
What is a Fuel Cell? A fuel cell is an electrochemical device that converts chemical energy from a fuel into electrical energy and heat. Fuel cells are similar to batteries in that they both convert chemical energy into electrical energy, but fuel cells do not run down and need to be recharged. Instead, they can … Read more
Compounds are defined as substances composed of two or more different Elements that are chemically combined. Both salt and water are compounds. Some important chemical compound and their uses are as follows:- NaCl sodium chloride (table salt, used in solutions for contact lens) ZnO zinc oxide (used in some sunscreens and diaper rash ointment) NaF … Read more
The Invisible Shield: Composition of the Atmosphere and Its Vital Role The Earth’s atmosphere, a seemingly invisible blanket enveloping our planet, plays a crucial role in sustaining life. It acts as a protective shield, regulating temperature, filtering harmful radiation, and facilitating weather patterns. Understanding the composition of this vital layer is essential for comprehending its … Read more
Sources of Energy: Conventional and Nonconventional Sources – Energy is one of the most important component of economic Biomass. These substances can be burnt to produce heat energy which can be used in the generation of electricity. Thus, the energy produced from the biomass is known as biomass energy. There are three forms of biomass: … Read more
Introduction Power is one of the most critical components of Biomass. Renewable energy is a clean source of energy. It does not produce greenhouse gas emissions. However, renewable energy sources are intermittent. They do not always produce power when it is needed. The fuel-based industries are facing a number of challenges. These challenges … Read more
