CHEMISTRY: A Hot Dip Before Swimming

Bond Strength of Hot – Dip Galvanized Reinforcement (b500b) with Concrete

P. Pokorný, D. Dobiáš, M. Vokáč – Czech Technical University – Klokner Institute, Prague, Czech Republic This paper evaluates the effect of initial corrosion damage to the surface of the hot dip galvanized steel coating in fresh concrete on its final bond strength. The tests were performed on uncoated and hot-dip galvanized ribbed reinforcements. The measurement of bond stress (τm) according to...

Exploring Carbide-Free Bainitic Structures for Hot Dip Galvanizing Products

Physics and chemistry of hot molecular cores

Young massive star-forming regions are known to produce hot molecular gas cores (HMCs) with a rich chemistry. While this chemistry is interesting in itself, it also allows to investigate important physical parameters. I will present recent results obtained with high-angular-resolution interferometers disentangling the small-scale structure and complexity of various molecular gas components. Ear...

Sulphur chemistry and evolution in hot cores

We compare the results of our JCMT spectral line survey of molecular gas towards ultracompact Hii regions with the predictions of models of sulphur chemistry in hot cores. We investigate the range of evolutionary models that are consistent with the observed physical conditions and chemical abundances, and see to what extent it is possible to constrain core ages by comparing abundances with the ...

Hot-spring chemistry and model proteins from a metagenome

This vignette for the CHNOSZ package demonstrates calculations of the relative stabilities of proteins with amino acid compositions derived from metagenomic data in a hot spring. The calculations are described in more detail in a recent paper [1]. The purpose of this document is to present a minimal amount of code to show how most of the figures in the paper can be generated. The code actually ...
