BIO GEO CHEMICAL CYCLE

Biogeochemical Cycle Definition. A biogeochemical cycle is one of several natural cycles, in which conserved matter moves through the biotic and abiotic parts of an ecosystem. In biology, conserved matter refers to the finite amount of matter, in the form of atoms, that is present within the Earth.

ECOLOGICAL PYRAMIDS

An ecological pyramid is a graphical representation of the relationship between the different living organisms at different trophic levels. It was given by G.Evylen Hutchinson and Raymond Lindeman. It can be observed that these pyramids are in the shape of actual pyramids with the base being the broadest, which is covered by the lowest trophic level, i.e., producers. The next level is occupied by the next trophic level, i.e., the primary consumers and so on. All the calculations for the construction of these types of ecological pyramids must take into account all the organisms in a particular trophic level because a sample space of a few numbers or a few species will end up giving a huge level of errors.

ENVIRONMENTAL CHEMISTRY AND WATER POLLUTION

Environmental chemistry is the scientific study of the chemical and biochemical phenomena that occur in natural places. It should not be confused with green chemistry, which seeks to reduce potential pollution at its source. It can be defined as the study of the sources, reactions, transport, effects, and fates of chemical species in the air, soil, and water environments; and the effect of human activity and biological activity on these. Environmental chemistry is an interdisciplinary science that includes atmospheric, aquatic and soil chemistry, as well as heavily relying on analytical chemistry and being related to environmental and other areas of science.

ethical dilemma

An ethical dilemma or ethical paradox is a decision-making problem between two possible moral imperatives, neither of which is unambiguously acceptable or preferable. The complexity arises out of the situational conflict in which obeying would result in transgressing another. also An ethical footprint is a way of measuring how much of an ethical consumer you are which is also included in this unit .

RECYCLING OF WASTE PAPER

THIS GIVES YOU THE KNOWLEDGE ABOUT THE PAPER RECYCLED FROM WASTED PAPERS, HOW IT IS DONE, WHAT ARE THE PROCESSES INVOLVED IN IT , IS IT GOOD/ BAD FOR ENVIROMENT, OTHER ENVIROMENTAL IMPACTS

TREATMENT OF TEXTILE DYEING WASTEWATER BY APPLYING PHOTO FENTON OXIDATON TECHNOLOGY

WE ALL KNOW THE TEXTILE INDUSTRY WHERE DYES ARE THE MOST IMPORTANT THINGS USED TO COLOURIFY THE CLOTHES. DYES ARE THE CHEMICAL COMPOSITION OF INORGANIC COMPOUNDS OF POLYMERS AND ORGANIC COMPOUNDS. MOST OF THE MILLS DO NOT USE COUNTER WASHING INSTEAD THEY USE CLEAN WATER IN EVERY CYCLE.SO, THE WASTE WATER GOES TO RIVERS AND OTHER WATER SOURCES CAUSING WATER POLLUTION AND ALSO HARMING THE ZOOPLANKTON AND PHYTOPLANKTON. HERE, IT DESCRIBES PHOTO-FENTON OXIDATION TECHNOLOGY TO USE THE WASTE WATER.

DEVELOPMENT OF THE CONCEPT "ALL WEATHER SOLAR CELLS"

Solar cells have been considered as one of the foremost solutions to energy and environmental problems because of clean, high efficiency, cost‐effective, and inexhaustible features. The historical development and state‐of‐the‐art solar cells mainly focus on elevating photoelectric conversion efficiency upon direct sunlight illumination. It is still a challenging problem to realize persistent high‐efficiency power generation in rainy, foggy, haze, and dark‐light conditions (night). The physical proof‐of‐concept for all‐weather solar cells opens a door for an upcoming photovoltaic revolution. Our group has been exploring constructive routes to build all‐weather solar cells so that these advanced photovoltaic technologies can be an indication for global solar industry in bringing down the cost of energy harvesting. How the all‐weather solar cells are built without reducing photo performances and why such architectures can realize electricity outputs with no visible‐light are discussed. Potential pathways and opportunities to enrich all‐weather solar cell families are envisaged. The aspects discussed here may enable researchers to develop undiscovered abilities and to explore wide applications of advanced photovoltaics.

Introduction to Environmental studies

Environmental studies are the study of human interaction with the environment and in the interests of solving complex problems. Environment includes which we are directly or indirectly dependent for our survival, whether it is living component like animals, plants or non living component like soil, air and water.
