Amorphous diamond structures with more than 97% of sp3 bonding fraction are generated by quenching liquid carbon using tight-binding molecular-dynamics simulations. The electronic and vibrational properties the amorphous sample investigated.

In this work, the performance of four electrolyte models for prediction the osmotic and activity coefficients of different aqueous salt solutions at 298 K, atmospheric pressure and in a wide range of concentrations are evaluated. In two of these models, (electrolyte Non-Random Two-Liquid e-NRTL and Mean Spherical Approximation-Non-Random Two-Liquid MSA-NRTL), association between ions of opposit...

background dermatophytosis is a cutaneous fungal infection with a worldwide occurrence. in dermatophyte infections, the release of keratinocyte cytokines, in the presence of dermatophyte antigens, causes an acute phase response; subsequently, the acute-phase proteins are produced by hepatocytes. mannose–binding lectin (mbl), an acute-phase protein, also acts as a kind of pattern recognition rec...

Paradigm-shifting advances have revealed that diverse membraneless organelles originate via liquid-liquid phase separation, but how their distinct structural and functional milieux are specified is not understood. Recent work elucidates that RNA governs the biophysical characteristics of liquid droplets formed by RNA-binding proteins with low-complexity domains and can decelerate pathogenic fib...

Eukaryotic mRNAs are monocistronic, and therefore mechanisms exist that coordinate the synthesis of multiprotein complexes in order to obtain proper stoichiometry at the appropriate intracellular locations. RNA-binding proteins containing low-complexity sequences are prone to generate liquid droplets via liquid-liquid phase separation, and in this way create cytoplasmic assemblages of functiona...

background: sperm vitrification is a technique of ice and cryoprotectant free cryopreservation by direct plunging of sperm suspension into liquid nitrogen (ln2). the aim of this study was to investigate the influence of cryoprotectant free-vitrification on human sperm fine structure by msome technology and the fertility potential by zona binding assay (zba). methods: 20 normo-ejaculates were pr...
