In order to shed light on the ionization process, it is useful to detect the ions in a mass spectrometer, which allows one to determine the mass of the ions. The scheme of the setup for mass-selective ion detection is shown in Fig. 10. The tunable laser light or the frequency-doubled...
The redistribution of Mn in MBEgrown In0.53Ga0.47 As layers containing different combinations of Mn and Gedoping pulses and subjected to various annealing conditions has been studied by secondary ion mass spectrometry(SIMS). The results indicate that Ge has a negligible diffusivity for temperatures up...
Manganese contributes to anti-oxidative stress particularly in catalase-devoid bacteria, and DtxR family metalloregulators, through sensing cellular Mn 2+ content, regulate its homeostasis. Here, we show that metalloregulator MntR (So-MntR) functions dually as Mn 2+ and H 2 O 2 sensors in media...
The manganese catalase gene (mnct) from Thermoleophilum album NM, a thermophilic bacterium, was cloned and its nucleotide sequence was analyzed. The gene consists of 885 bp (65.4% GC content) encoding 294 amino acids with a molecular mass of 32,500 Da. The deduced amino acid sequence shows...
As compared to the extensively studied manganese oxide, only a few molecular Mn-based catalysts were developed. Meanwhile, the drawback of these so-called “homogeneous Mn catalysts” is Conclusions Over the last few decades, a huge number of molecular catalysts based on transition metals were ...

Occupational and environmental exposure to Co and Cr has been previously linked to a wide array of inflammatory and degenerative conditions and cancer. Recently, significant health concerns have been raised by the high levels of Cr and Co ions and corros
Higher but similar (p > 0.05) protein levels were found in CtTun15 and TaTun15 strains with a mean value of 30.63 ± 0.06 g/100 gDW; the highest content was found in Debaryomyces hansenii DhTun2015 strain with 32.13 ± 0.28 g/100 g corresponding to 40% of the yeast dry mass. Such...
The predictive power of molecular-scale techniques can be harnessed by estimating physicochemical properties of materials for use in novel chemistries, such as lithium metal batteries and the Li-ion lithium nickel manganese oxide (LNMO) chemistry. This paradigm would be valuable for scaling up ...
