Two-dimensional (2D) nanomaterials constitute one of the most advanced research targets in materials science and engineering this century. Among various methods for synthesis 2D nanomaterials, including top-down exfoliation bottom-up crystal growth, chemical has been widely used to yield monolayers layered compounds, such as clay minerals, transition metal chalcogenides (TMDCs), oxides, long be...

Labeling chemically for a "single" result: A one-step, nonenzymatic 5hmC thiolation method mediated by bisulfite is highlighted. The 5hmC base can be chemically labeled in single-stranded DNA and detected by using nanopore sequencing.

The position of diierent kinds of CP stars of the upper Main Sequence (i.e. Am stars and the four categories of Ap stars: He-weak, HgMn, Si and SrCrEu) in the HR diagram is examined. Using only those stars having a parallax with a relative error smaller than 0.14 ((M v) 0:3) and an absolutely certain peculiarity, it is shown that their absolute magnitudes are similar to those obtained from CP s...

For the purpose of deriving the helium abundances in chemically peculiar stars, the importance of assuming a correct helium abundance has been investigated for determining the effective temperature and gravity of main sequence B-type stars, making full use of the present capability of reproducing their helium lines. Even if the flux distribution of main sequence B-type stars appears to depend o...

We consider a continuum model for chemically-induced volume transitions in hydrogels. Consistent with experimental observations, the theory allows for a sharp interface separating swelled and collapsed phases of the underlying polymer network. The polymer chains are treated as a solute with an associated diffusion potential and their concentration is assumed to be discontinuous across the inter...
