A simple procedure for introducing functional exogenous membrane-bound proteins to viable cells encapsulated within a lipid templated silica nanostructure is described. In one method, bacteriorhodopsin (bR) was added directly to a Saccharomyces cerevisiae solution along with short zwitterionic diacylphosphatidylcholines (diC(6) PC) and mixed with equal volumes of a sol precursor solution. Alter...

Background: Based on the dynamics of antigen recognition from T cell receptor complex and T cell activation, different function of T cells may present different morphology feature, at least at molecular level. Regulatory T (Treg) cells play a critic role in regulation the onset of graft versus host disease (GVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Little is kn...

as a new precursor, [tris(2-hydroxyacetophenato) triaqua(iii)], [y(hap)3(h2o)3]; complex was used in thermal decomposition process for the synthesis of rod-like high-temperature ceramic ybco with length of about 320-350 nm and diameters 60–90 nm. the as-synthesized products were characterized by xrd, ft-ir, tem, sem and edx analyses. the results showed that by using fine raw materials, the calc...

A combinatorial high-throughput approach is used to investigate a solution cast gradient consisting of colloidal gold nanoparticles on top of a silicon substrate by means of a X-ray nanobeam. Classification algorithms are used to reveal and visualize structural transitions from a frozen colloidal solution to a well-defined nanostructure. Prominent length scales on the order of 100 nm are observ...

the reported work is on the preparation and characterization of polyvinyl alcohol -g- polyacrylic acid (pva-g-paa)/ polybenzimidazole sulfone (pbis) cation exchange membrane used for the electro dialysis of sodium chloride solution. the polymer syrup has been prepared using the grafting method with the help of polyvinyl alcohol and polyacrylic acid in the presence of water solvent. the polymer ...

Computational methods can play a significant role in characterization of the carbon-based nanocomposites by providing simulation results. In this paper, we prepared a brief review of the mechanical properties of carbon nanotubes (CNTs), Graphene, and coiled carbon nanotube (CCNTs) reinforced nanocomposites. Varies simulation studies in mechanical properties of nanocomposites including represent...

A double-layer nanostructure comprising amorphous Si nanograss on top of Si nanofrustums (NFs) with a total height of 680 nm exhibits ultralow reflection. Almost near-unity absorption and near-zero reflectance result in this layered nanostructure, over a broad range of wavelengths and a wide range of angles of incidence, due to the low packing density of a-Si and the smooth transition of the re...

Exceptionally large surface area and well-defined nanostructure are both critical in the field of nanoporous carbons for challenging energy and environmental issues. The pursuit of ultrahigh surface area while maintaining definite nanostructure remains a formidable challenge because extensive creation of pores will undoubtedly give rise to the damage of nanostructures, especially below 100 nm. ...
