“…Let us now turn to the binding energies, and more particularly to B D that, as we have seen, is a crucial parameter. This is one the better known quantities in the nuclear domain and it is experimentally measured to a precision better than 10 −6 [18]. Two approaches have been followed.…”

Fundamental constants are a cornerstone of our physical laws. Any constant varying in space and/or time would reflect the existence of an almost massless field that couples to matter. This will induce a violation of the universality of free fall. Thus, it is of utmost importance for our understanding of gravity and of the domain of validity of general relativity to test for their constancy. We detail the relations between the constants, the tests of the local position invariance and of the universality of free fall. We then review the main experimental and observational constraints that have been obtained from atomic clocks, the Oklo phenomenon, solar system observations, meteorite dating, quasar absorption spectra, stellar physics, pulsar timing, the cosmic microwave background and big bang nucleosynthesis. At each step we describe the basics of each system, its dependence with respect to the constants, the known systematic effects and the most recent constraints that have been obtained. We then describe the main theoretical frameworks in which the low-energy constants may actually be varying and we focus on the unification mechanisms and the relations between the variation of different constants. To finish, we discuss the more speculative possibility of understanding their numerical values and the apparent fine-tuning that they confront us with.

“…Because of the carefulwork of the successive evaluators, the AME has gained a good reputation and serves as the standard mass table. A series of AME mass tables have been published since its inception in the 1950's [2], with the latest one, AME2012, published in December, 2012 [3,4].…”

The Atomic Mass Evaluation (AME) contains the most reliable and comprehensive information for the values of the atomic masses and their uncertainties. A wealth of new, high-precision experimental data were included in the new version, AME2012, published in December 2012, and masses of many nuclides were improved significantly. The AME2012 is described and compared with the previous AME2003 evaluation. Perspectives about the future are given.

“…The third important discovery for SFC-MS was the discovery of the Mass Spectrograph. The blueprint for the modern spectrometer was a Mass Spectrograph constructed in 1918-19 by Arthur J. Dempster and Francis W. Aston [12]. As for chromatography, the discovery and construction of MS were predicated on a long line of observations described by famous scientists starting from Julius Plücker in 1869, and Johann Wilhelm Hittorfand Eugen Goldstein, who in 1876 discovered and named the rays in gas discharges under low pressure as "Kanalstrahlen" or "canal rays" [13].…”

In 1822, almost 200 years ago, Baron Charles Cagniard de Latour (1777-1859) discovered the critical phenomena or critical state [1] [2]. At that time, it was described as a curiosity. However, it is now used as an advanced extraction and analytical technology in industry and research. Extraction with supercritical fluids (SFs) was welcome from the very beginning. In the present paper, the application to chromatography of the critical phenomena of compressed gases or overheated liquids as supercritical fluids will be discussed. Supercritical Fluid Chromatography (SFC) received an uneasy welcome, mainly because of the lack of commercially available analytical instruments. Even today, only a small number of industrial companies are manufacturing SFC instrumentation. A very small spectrum of columns is manufactured specially for SFC. SFC is not accepted by Pharmacopeia committees for the analysis of drugs and medical forms to the same extent as Gas Chromatography, High-Performance Liquid Chromatography or even Thin Layer Chromatography. The present status and future perspectives for SFC will be discussed.
