The following is a list of GCE Ordinary Level subjects offered by Cambridge International Examinations (CAIE).You can choose from more than 40 subjects in any combination. [ 1 ] Cambridge O Levels, Cambridge IGCSE and/or Cambridge International Level 1 or Level 2 Certificates may be taken in the same examination session but certain combinations ...
These modules and courseworks for a specific A Level combine to give a total UMS mark. For example, an A level Chemistry course might consist of 4 exams worth 90 UMS and 2 exams worth 120 UMS, totalling a maximum of 600 UMS. From 2008 onward, many subjects moved from 600 to 400 UMS for the A-level, and from 300 to 200 UMS for the AS.
This paper introduced several of the cornerstones of physical chemistry, such as Gibbs energy, chemical potentials, and Gibbs' phase rule. [10] The first scientific journal specifically in the field of physical chemistry was the German journal, Zeitschrift für Physikalische Chemie, founded in 1887 by Wilhelm Ostwald and Jacobus Henricus van 't ...
However, they are distinguished from thermosets by the incorporation of dynamic covalent chemistry into the polymer network. When a stimulus (for example heat, light, pH, ...) is applied to the material, these dynamic bonds become active and can be broken or exchanged with other pending functional groups , allowing the polymer network to change ...
Car–Parrinello molecular dynamics or CPMD refers to either a method used in molecular dynamics (also known as the Car–Parrinello method) or the computational chemistry software package used to implement this method. [1] The CPMD method is one of the major methods for calculating ab-initio molecular dynamics (ab-initio MD or AIMD).
This allows for a dynamic redistribution of charge between atoms which responds to the local chemical environment. For many years, polarizable MD simulations have been touted as the next generation. For homogenous liquids such as water, increased accuracy has been achieved through the inclusion of polarizability.
Reaction dynamics is a field within physical chemistry, studying why chemical reactions occur, how to predict their behavior, and how to control them. It is closely related to chemical kinetics , but is concerned with individual chemical events on atomic length scales and over very brief time periods. [ 1 ]
