The Physical Chemistry In Brief offers a digest of all major formulas, terms and definitions
needed for an understanding of the subject. They are illustrated by schematic figures, simple
worked-out examples, and a short accompanying text. The concept of the book makes it
different from common university or physical chemistry textbooks. In terms of contents, the
Physical Chemistry In Brief embraces the fundamental course in physical chemistry as taught
at the Institute of Chemical Technology, Prague, i.e.
The sub-series Ternary Alloy Systems of the Landolt-Börnstein New Series provides reliable and
comprehensive descriptions of the materials constitution, based on critical intellectual evaluations of all
data available at the time and it critically weights the different findings, also with respect to their
compatibility with today’s edge binary phase diagrams. Selected are ternary systems of importance to
alloy development and systems which gained in the recent years otherwise scientific interest.
Some people make physical chemistry sound more confusing than it really is. One of
their best tricks is to define it inaccurately, saying it is ‘the physics of chemicals’. This
definition is sometimes quite good, since it suggests we look at a chemical system and
ascertain how it follows the laws of nature. This is true, but it suggests that chemistry
is merely a sub-branch of physics; and the notoriously mathematical nature of physics
impels us to avoid this otherwise useful way of looking at physical chemistry....

Có một số phản ứng hóa học phức tạp có thể xảy ra trong đất. Những phản ứng khác nhau tương tác với nhau thông qua các giải pháp đất (Hình 4.1). Các dung dịch đất được định nghĩa là giai đoạn lỏng dung dịch nước của đất và các chất tan của nó (Bảng thuật ngữ của Điều khoản Khoa học Đất, 1997).
The hero in The Name of the Rose is a medieval English monk. He acts as sleuth,
the derivation of a
and is heard to note at one point in the story how, ‘The study of words is the
whole of knowledge’. While we might wish he had gone a little
further to mention chemicals, we would have to agree that many
of our technical words can be traced back to Latin or Greek roots.
The remainder of them originate from the principal scientists who
pioneered a particular field of study, known as etymology....
X-ray diffraction is a tool for the investigation of the fine structure of
matter. This technique had its beginnings in von Laue's discovery in 1912
that crystals diffract x-rays, the manner of the diffraction revealing the
structure of the crystal. At first, x-ray diffraction was used only for the
determination of crystal structure.
The process of analyte retention in high-performance liquid chromatography (HPLC) involves many different aspects of molecular behavior and interactions in condensed media in a dynamic interfacial system. Molecular diffusion in the eluent ﬂow with complex ﬂow dynamics in a bimodal porous space is only one of many complex processes responsible for broadening of the chromatographic zone.
