Reaction Dynamics

#MatCongress2021

Reaction dynamics deals with the intra- and intermolecular motions that characterize the elementary act of a chemical reaction. It also deals with the quantum states of the reactants and product. Chemical reaction mechanisms are of central importance to organic, inorganic, and biochemistry.

Molecular Dynamics

#MatCongress2021

Molecular dynamics is another approach for the investigation of the atom location in space. In this approach, a single-point model is replaced by a dynamic model in which the nuclear system is forced into motion. Molecular dynamics can be used to explore conformational space, and is often the method of choice for large molecules such as proteins. Molecular dynamics simulation is becoming an invaluable tool for studying bimolecular structure and dynamics, the relationship between which is central to understanding important cellular processes.

Semiconductor Devices

#MatCongress2021

Semiconductor device, electronic circuit component made from a material that is neither a good conductor nor a good insulator. Such devices have found wide applications because of their compactness, reliability, and low cost. The conductivity of a semiconductor is generally sensitive to temperature, illumination, magnetic fields, and minute amounts of impurity atoms. Many of the compound semiconductors have electrical and optical properties that are absent in silicon. These semiconductors, especially gallium arsenide, are used mainly for high-speed and optoelectronic applications.

Bio-material Mechanics

#MatCongress2021

The mechanical behavior of biomedical materials and biological tissues are important for their proper function. Mechanics of biomaterials are essential for prevention, diagnosis, planning, and treatment of diseases. The focus of this research topic is on applying the engineering principle, material science and biology for better understanding the mechanical behaviors of biomaterials and developing new materials.

Endothermic Reactions

#MatCongress2021

Endothermic reactions are chemical reactions in which the reactants absorb heat energy from the surroundings to form products. These reactions lower the temperature of their surrounding area, thereby creating a cooling effect. Physical processes can be endothermic as well – Ice cubes absorb heat energy from their surroundings and melt to form liquid water.

Organic Pollutants

#MatCongress2021

Organic pollutants include many insecticides and herbicides that have been used in agriculture and pest control. Organic pollutants arise many a times due to their extreme toxicity at very low level of exposure as well as their high persistency in the soil. Most common groups of organic pollutants in soil including polycyclic aromatic hydrocarbons, polychlorinated biphenyls, pesticides, dye pollutants, antibiotics are discussed for their sources, fate and impact on the ecosystem.

Electron Shell

#MatCongress2021

An electron shell is the outside part of an atom around the atomic nucleus. It is a group of atomic orbitals with the same value of the principal quantum number n. Electron shells have one or more electron subshells, or sublevels. An electron shell may be thought of as an orbit followed by electrons around an atom nucleus. Because each shell can contain only a fixed number of electrons, each shell is associated with a particular range of electron energy, and thus each shell must fill completely before electrons can be added to an outer shell. The electrons in the outermost shell determine the chemical properties of the atom.

Lewis Acid

#MatCongress2021

A Lewis acid is defined as an electron-pair acceptor, whereas a Lewis base is an electron-pair donor. The neutralization reaction is one in which a covalent bond forms between an electron-rich species and an electron-poor species. This definition is useful because it not only covers all the acid-base chemistry with which we are already familiar, but it describes reactions that cannot be modeled by Arrhenius or Bronsted-Lowry acid-base chemistry.

Molecular Recognition

#MatCongress2021

Molecular recognition is the specific interaction between two or more molecules, which exhibit molecular complementarity, through noncovalent bonding such as hydrogen bonding, metal coordination. Molecular recognition is a biological phenomenon which realizes special recognition at molecular level in living and chemical systems. The origin of the process lies in the intrinsic capacity of biomolecules to distinguish between other compounds and interact with them on the base of their molecular complementarities.

Molecular Sensors

#MatCongress2021

A molecular sensor, also known as a chemosensor or probe, is a molecular or supramolecular-based system that is able to transform probe–analyte interactions into a signal which allows analyte sensing. The most common output signals are usually optical or electrochemical changes. The design of these molecular sensors and probes has advanced and gained importance in the last years due to the progress made in the knowledge on the preparation of host–guest complexes and on studies on how this interaction can be used for the design of selective molecular probes. This is a very interdisciplinary filed that in many cases involves organic or inorganic synthesis, photo-physical studies, and analytical applications.
