Arrows of time and fundamental symmetries in chemical physics

, 2013
The field of chemical and physical processes, using principal microscopic techniques, should today allegedly be identified as a fundamental branch of physics.

Chemical and Physical Characteristics [PDF]

, 1989
Regarding chemical and physical characteristics of solder paste, the coverage in certain areas is inevitably discussed in general terms in order to avoid proprietary information.

LDH in Physical, Chemical, Biochemical, and Life Sciences

2013
After a brief recall of layered double hydroxides (LDH) features to underline the reasons of the present exponential growth of the number of patents and papers dealing with application in several sometime unexpected fields, the chapter will deal only with selected applications, namely, (1) environmental protection and agricultural aids; (2 ...

Physical and Chemical Sensors

2011
In this chapter we give an introduction and classification on some examples of physical sensors (devices placed at the input of an instrumentation system that quantitatively measures a physical parameter, for example pressure, displacement or temperature) and chemical sensors (devices which are part of an instrumentation system that determines ...

Physical and Chemical Weathering

2015
As one geologist exclaimed: “Savor the irony should the metamorphic muscles that push mountains to the sky be driven by the pitter patter of tiny raindrops.” In the following chapters we look at this pitter patter, a synonym for exogenic processes that shape our landforms, starting with the most important process: weathering.

Chemical and Physical Bonding

1995
Electron Pair Orbitals. A practical understanding of ceramic processing requires some knowledge of chemical bonding. Weak bonds, strong bonds, and some bond types not ordinarily emphasized in first year chemistry courses are all involved in a typical ceramic process, even for an old method such as the slip casting of ball clay.

Physical-Chemical Properties [PDF]

, 1987
Among the nucleic acids, the single-stranded RNA molecules have the highest potential to form a large variety of structures and to undergo quite different structural transitions. The determination of their structure and structural transitions is a prerequisite for understanding their function in replication, transcription, translation, and regulation ...

Physical and Chemical Principles

2011
The land surface affects the atmosphere via the exchange of heat, matter (moisture, gases, aerosols), and momentum. The exchange of heat and moisture, for instance, are described by the energy and water budgets that are coupled via the water-vapor flux due to evapotranspiration (i.e., the sum of transpiration and evaporation). Coupled energy- and water-

Chemical and physical “hardness”

Materials Research Innovations, 1997
A common theme links chemical, mechanical, and optical hardnesses. It is the gap in the bonding energy spectra of materials. This gap determines molecular stability, and therefore ”chemical hardness”. Chemists call it the LUMO-HOMO gap between anti-bonding and bonding molecular orbitals.
