The Impact of the Surface Modification on Tin-Doped Indium Oxide Nanocomposite Properties.

This review provides an analysis of the theoretical methods to study the effects of surface modification on structural properties of nanostructured indium tin oxide (ITO), mainly by organic compounds. The computational data are compared with experimental data such as X-ray diffraction (XRD), atomic force microscopy (AFM) and energy-dispersive X-ray spectroscopy (EDS) data with the focus on optoelectronic and electrocatalytic properties of the surface to investigate potential relations of these properties and applications of ITO in fields such as biosensing and electronic device fabrication. Our analysis shows that the change in optoelectronic properties of the surface is mainly due to functionalizing the surface with organic molecules and that the electrocatalytic properties vary as a function of size.

Application of MIL-53(Al) prepared from waste materials for solid-phase microextraction of propranolol followed by corona discharge-ion mobility spectrometry (CD-IMS).

In this study, MIL-53(Al) metal-organic framework was prepared from waste raw materials. A polyethylene terephthalate (PET) plastic bottle was used as the source of terephthalic acid, and an aluminium beverage can was applied as the precursor of aluminium salt. The activated MIL-53(Al) was immobilized onto a stainless steel probe of the ion mobility spectrometer (IMS), and the coated probe was used for solid-phase microextraction of propranolol from biological samples before determination.

Temperature dependent dynamics in highly homologous adenylate kinases.

To correlate the structural features of enzymes to temperature adaptation, we studied psychrophile, mesophile, and thermophile adenylate kinases as model enzymes using bioinformatics and computational tools. Phylogenetic analysis revealed that mesophile and thermophile variants are clustered in one stem of phylogenetic tree and are close to contemporary time, while psychrophile enzyme is more close to their common ancestor. This finding is in good agreement with the process of environmental changes from ice age toward current warm conditions on the earth.

Separation based adsorption of ethanol-water mixture in azeotropic solution by single-walled carbon, boron-nitride and silicon-carbide nanotubes.

The separation of the azeotropic ethanol-water mixture (95.57wt% ethanol) over a wide range of pressures (100-100000kPa) was studied on armchair SWCNTs, SWSiCNTs and SWBNNTs with different diameters at 351.30K using GCMC simulations.
