13^th International Conference on Chemistry Meeting April 25-26, 2023 Paris, France

The study of phenomena and the manipulation of materials at the atomic, molecular, and macromolecular scales, where properties are markedly different from those at a larger scale, is known as Nanoscience. By manipulating shape and size at the nanoscale, nanotechnologies enable the design, characterization, manufacture, and application of structures, devices, and systems are called Nanotechnology. The modelling of nanoscale objects, materials, and interactions is a crucial part of nanotechnology. Technology advancement depends on understanding the underlying science of nanoscale interactions. One of the primary areas of study in the field of nanotechnology is these interactions.

Organic chemistry is a chemistry sub discipline involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms. Study of structure includes many physical and chemical methods to determine the chemical composition and the chemical constitution of organic compounds and materials. Study of properties includes both physical properties and chemical properties, and uses similar methods as well as methods to evaluate chemical reactivity, with the aim to understand the behaviour of the organic matter in its pure form (when possible), but also in solutions, mixtures, and fabricated forms. The study of organic reactions includes probing their scope through use in preparation of target compounds (e.g., natural products, drugs, polymers, etc.) by chemical synthesis, as well as the focused study of the reactivity’s of individual organic molecules, both in the laboratory and via theoretical study. Inorganic chemistry deals with the synthesis and behaviour of inorganic and organometallic compounds. This field covers all chemical compounds except the myriad organic compounds (carbon-based compounds, usually containing C-H bonds), which are the subjects of organic chemistry. The distinction between the two disciplines is far from absolute, as there is much overlap in the sub discipline of organometallic chemistry. It has applications in every aspect of the chemical industry, including catalysis, materials science, pigments, surfactants, coatings, medications, fuels, and agriculture.

Analytical techniques spans nearly all areas of chemistry but involves the development of tools and methods to measure physical properties of substances and apply those techniques to the identification of their presence (qualitative analysis) and quantify the amount present (quantitative analysis) of species in a wide variety of settings, analytical chromatography will be used in various fields for separation and analytical biochemistry is used to detect various samples. Chemistry Conferences focuses on electrochemical methods, quality assurance, qualitative analysis, quantifying nature, quantitative analysis, gravimetric methods, evaluating analytical data, spectroscopic methods and Standardizing analytical methods.

Green chemistry, also called sustainable chemistry, is an area of chemistry and chemical engineering focused on the designing of products and processes that minimize the use and generation of hazardous substances. Environmental chemistry focuses on the effects of polluting chemicals on nature whereas green chemistry focuses on the environmental impact of chemistry, including technological approaches to preventing pollution and reducing consumption of non-renewable resources.

Physical Chemistry is the study of macroscopic, atomic, subatomic, and particulate phenomena in chemical systems in terms of the principles, practices, and concepts of physics such as motion, energy, force, time, thermodynamics, quantum chemistry, statistical mechanics, analytical dynamics and chemical equilibrium. , in contrast to chemical physics, is predominantly (but not always) a macroscopic or supra-molecular science, as most of the principles on which it was founded relate to the bulk rather than the molecular/atomic structure alone (for example, chemical equilibrium and colloids).

Theoretical chemistry is the examination of the structural and dynamic properties of molecules and molecular materials using the tools of quantum chemistry, equilibrium and no equilibrium statistical mechanics and dynamics. Theoretical chemistry seeks to provide theories and explanations for chemical observations whilst also posing questions to be answered by future experiments. Playing a key role in physical chemistry, it uses the laws of physics to predict molecular structure, dynamics, bonding, reactivity, physical properties and spectroscopic response.

Polymer chemistry is a sub-discipline of chemistry that focuses on the chemical synthesis, structure, chemical and physical properties of polymers and macromolecules. The principles and methods used for polymer chemistry are common to chemistry sub-disciplines organic chemistry, analytical chemistry, and physical chemistry. Many materials have polymeric structures, from fully inorganic metals and ceramics to DNA and other biological molecules, however, polymer chemistry is typically referred to in the context of synthetic, organic compositions. Synthetic polymers are ubiquitous in commercial materials and products in everyday use, commonly referred to as plastics, rubbers, and composites. Polymer chemistry can also be included in the broader fields of polymer science or even nanotechnology, both of which can be described as encompassing polymer physics and polymer engineering.

Pharmaceutical chemistry is the study of drugs, and it involves drug development. This includes drug discovery, delivery, absorption, metabolism, and more. There are elements of biomedical analysis, pharmacology, pharmacokinetics, and pharmacodynamics. Pharmaceutical chemistry work is usually done in a lab setting. Pharmaceutical chemistry involves cures and remedies for disease, analytical techniques, pharmacology, metabolism, quality assurance, and drug chemistry. Many pharmaceutical chemistry students will later work in a lab. Pharmaceutical chemistry leads to careers in drug development, biotechnology, pharmaceutical companies, research facilities, and more. Studying pharmaceutical chemistry allows students to contribute to life-saving remedies, enhance the speed of delivery of new medications, and help others. Pharmaceutical chemistry also includes other branches of study such as pharmacokinetics, pharmacodynamics, and drug metabolism. These are important for learning the effects that drugs have on the body.

Materials chemistry involves the use of chemistry for the design and synthesis of materials with interesting or potentially useful physical characteristics, such as magnetic, optical, structural or catalytic properties. The interdisciplinary field of materials science, also commonly termed materials science and engineering involves the discovery and design of new materials, with an emphasis on solids. The intellectual origins of materials science stem from the Enlightenment, when researchers began to use analytical thinking from chemistry, physics, and engineering to understand ancient, phenomenological observations in metallurgy and mineralogy. Materials science still incorporates elements of physics, chemistry, and engineering. As such, the field was long considered by academic institutions as a sub-field of these related fields. Beginning in the 1940s, materials science began to be more widely recognized as a specific and distinct field of science and engineering, and major technical universities around the world created dedicated schools of the study. Materials science is a syncretic discipline hybridizing metallurgy, ceramics, solid-state physics, and chemistry. It is the first example of a new academic discipline emerging by fusion rather than fission. Thus, breakthroughs in materials science are likely to affect the future of technology significantly.

Biochemistry can be defined as the science concerned with the chemical basis of life. The cell is the structural unit of living organisms. Thus, biochemistry can also be described as the science concerned with the chemical constituents of living cells and with the reactions and processes, they undergo. By this definition, biochemistry encompasses large areas of cell biology, of molecular biology, and of molecular genetics. The major objective of biochemistry is the complete understanding, at the molecular level, of all of the chemical processes associated with living cells. To achieve this objective, biochemists have sought to isolate the numerous molecules found in the cells, determine their structures, and analyse how they function.

Clinical chemistry (also known as chemical pathology, clinical biochemistry or medical biochemistry) is the area of chemistry that is generally concerned with analysis of bodily fluids for diagnostic and therapeutic purposes. It is an applied form of biochemistry (not to be confused with medicinal chemistry, which involves basic research for drug development). The discipline originated in the late 19th century with the use of simple chemical reaction tests for various components of blood and urine. In the many decades since, other techniques have been applied as science and technology have advanced, including the use and measurement of enzyme activities, spectrophotometry, electrophoresis, and immunoassay. There are now many blood tests and clinical urine tests with extensive diagnostic capabilities.
