The current model of atomic structure is the quantum mechanical model. Traditional chemistry starts with the study of elementary particles, atoms, molecules, substances, metals, crystals and other aggregates of matter. This matter can be studied in solid, liquid, or gas states, in isolation or in combination. The interactions,
reactions and transformations that are studied in chemistry are usually
the result of interactions between atoms, leading to rearrangements of
the chemical bonds which hold atoms together. Such behaviors are studied
in a chemistry laboratory.
The chemistry laboratory stereotypically uses various forms of laboratory glassware.
However glassware is not central to chemistry, and a great deal of
experimental (as well as applied/industrial) chemistry is done without
it.
A chemical reaction is a transformation of some substances into one or more different substances.
The basis of such a chemical transformation is the rearrangement of
electrons in the chemical bonds between atoms. It can be symbolically
depicted through a chemical equation,
which usually involves atoms as subjects. The number of atoms on the
left and the right in the equation for a chemical transformation is
equal. (When the number of atoms on either side is unequal, the
transformation is referred to as a nuclear reaction or radioactive decay.)
The type of chemical reactions a substance may undergo and the energy
changes that may accompany it are constrained by certain basic rules,
known as chemical laws.
Energy and entropy considerations are invariably important in almost all chemical studies. Chemical substances are classified in terms of their structure, phase, as well as their chemical compositions. They can be analyzed using the tools of chemical analysis, e.g. spectroscopy and chromatography. Scientists engaged in chemical research are known as chemists.Most chemists specialize in one or more sub-disciplines. Several concepts are essential for the study of chemistry; some of them are:
Chemistry is typically divided into several major sub-disciplines.
There are also several main cross-disciplinary and more specialized
fields of chemistry.
Analytical chemistry is the analysis of material samples to gain an understanding of their chemical composition and structure.
Analytical chemistry incorporates standardized experimental methods in
chemistry. These methods may be used in all subdisciplines of chemistry,
excluding purely theoretical chemistry.
Biochemistry is the study of the chemicals, chemical reactions and chemical interactions that take place in living organisms. Biochemistry and organic chemistry are closely related, as in medicinal chemistry or neurochemistry. Biochemistry is also associated with molecular biology and genetics.
Inorganic chemistry
is the study of the properties and reactions of inorganic compounds.
The distinction between organic and inorganic disciplines is not
absolute and there is much overlap, most importantly in the
sub-discipline of organometallic chemistry.
Materials chemistry
is the preparation, characterization, and understanding of substances
with a useful function. The field is a new breadth of study in graduate
programs, and it integrates elements from all classical areas of
chemistry with a focus on fundamental issues that are unique to
materials. Primary systems of study include the chemistry of condensed
phases (solids, liquids, polymers) and interfaces between different phases.
Neurochemistry
is the study of neurochemicals; including transmitters, peptides,
proteins, lipids, sugars, and nucleic acids; their interactions, and the
roles they play in forming, maintaining, and modifying the nervous
system.
Nuclear chemistry is the study of how subatomic particles come together and make nuclei. Modern Transmutation is a large component of nuclear chemistry, and the table of nuclides is an important result and tool for this field.
Organic chemistry is the study of the structure, properties, composition, mechanisms, and reactions of organic compounds. An organic compound is defined as any compound based on a carbon skeleton.
Physical chemistry
is the study of the physical and fundamental basis of chemical systems
and processes. In particular, the energetics and dynamics of such
systems and processes are of interest to physical chemists. Important
areas of study include chemical thermodynamics, chemical kinetics, electrochemistry, statistical mechanics, spectroscopy, and more recently, astrochemistry. Physical chemistry has large overlap with molecular physics. Physical chemistry involves the use of infinitesimal calculus in deriving equations. It is usually associated with quantum chemistry and theoretical chemistry. Physical chemistry is a distinct discipline from chemical physics, but again, there is very strong overlap.
Theoretical chemistry is the study of chemistry via fundamental theoretical reasoning (usually within mathematics or physics). In particular the application of quantum mechanics to chemistry is called quantum chemistry. Since the end of the Second World War, the development of computers has allowed a systematic development of computational chemistry, which is the art of developing and applying computer programs for solving chemical problems. Theoretical chemistry has large overlap with (theoretical and experimental) condensed matter physics and molecular physics.

Answer: ACASC charges a service fee of 50$ for using its online application portal. Applying through ACASC into Chinese universities attracts a service fee of $50.
Answer: Yes. ACASC gives the applicants, the chance to directly apply to their desired universities through our online application portal. We have synchronized our system to create a simple platform that connects universities and colleges in China to international students all around the world.
Answer: To track the application status, please log in your ACASC personal account. Whenever there’s an update, you will be informed on your application status through ACASC system within a day as soon as we receive university’s notification. You will simultaneously receive ACASC auto-email about the application status. To directly inquire about your application status, feel free to send us an email to admission@acasc.cn and our team will keep you updated.
Answer: When an application is pending a decision it means that your school has received it and no admissions decision has been made yet. The admissions office may have reviewed your application package or may not have.
The main cause of a pending application is usually incomplete application documents. As a result you will be requested by the school’s admission office to re-check and modify all submitted application documents or perhaps even add extra documents and then re-submit them.
To avoid further delays, carefully read the university’s comments, modify your application form on ACASC, and re-upload the required application documents. You can contact ACASC on admission@acasc.cn for any help with regards to your pending application
Processing time varies for different applications. For example to process a degree program application requires more time than a Chinese language application. Confirmation for Chinese language application by the admission office usually takes 2 to 4 weeks. However, time for degree programs application differs. For example fall semester application processing is after March, and it takes a period of 1 to 2 months. This also depends on your qualification and the number of applicants.
