The Interaction Between Facts, Ideas, and Language in Lavoisier\u27s Chemistry Practice: The Case of the Study of the Composition of Air [PDF]

, 2013
According to Lavoisier the physical sciences embody three important ingredients; facts, ideas, and language. Ideas had to be consistent with the facts generated from experiment and observation, and language needed to be precise and reflect the known ...

Physics of Transport and Traffic Phenomena in Biology: from molecular motors and cells to organisms

, 2005
Traffic-like collective movements are observed at almost all levels of biological systems. Molecular motor proteins like, for example, kinesin and dynein, which are the vehicles of almost all intra-cellular transport in eukayotic cells, sometimes ...

Magnetic field modulation of the delayed fluorescence yield in the photoionization reaction of N, N, N', N'-tetramethyl-p-phenylenediamine in water

International Journal of Photoenergy, 1999
External magnetic field effects on the recombination fluorescence (MARY effect) in the photoionization reaction of N,N,N′,N′-Tetramethyl-p-phenylenediamine (TMPPD) in water and DMSO/water mixture are studied. Relatively large magnetic field effects (MFE),

On Emerging Fields of Quantum Chemistry at Finite Temperature [PDF]

arXiv, 2004
In this article, we present an emerging field of quantum chemistry at finite temperature. We discuss its recent developments on both theoretical and experimental fronts.We describe and analyze several experimental investigations related to the temperature effects on the structure, electronic spectra,or bond rupture forces for molecules.

Adsorption of Ferricyanide Ion onActivated Carbon and γ-Alumina

E-Journal of Chemistry, 2010
Iron-cyanide complexes are present in soil and ground water due to anthropogenic inputs. We compared the adsorption of ferricyanide ion, on two commercial activated carbons (COM3 and COM4) and γ-alumina (A1G) in aqueous solution.

Rapid Determination of Hexane Residues in Refined Vegetable Oils Using Semiconducting Metal Oxide-Based Sensors

Proceedings
A simple, direct method for the determination residual hexane content in refined oils was developed, which makes use of commercial Semiconducting Metal Oxides (SMOX) sensors and is proposed as an alternative to the currently used standards (ISO 9832:2002,
