Thin polystyrene (PS) films with highly ordered honeycomb pattern were successfully fabricated by an improved phase separation method. The PS film was successfully crosslinked after applying a deep UV irradiation. This work presents a proof of crosslinking PS by characterizing ATR-FTIR, TGA and the wetting property of the honeycomb films, which were prepared using a solvent/non-solvent ratio of...

Principal component regression (PCR) was used to develop calibration and prediction models for determination of mineral content of complex mineral mixtures by utilizing attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectra. The typical constituents of oil shale such as dawsonite, nahcolite, quartz, dolomite, illite, albite, analcime, and kerogen were used to prepare samples...

The wide range of symptoms the coronavirus disease 2019 (COVID-19) makes it challenging to predict evolution using a single parameter. Therefore, describe pathophysiological response SARS-CoV-2 infection in hospitalized patients with severe COVID-19, we compared according survival or death, sociodemographic and clinical characteristics, biochemical immunological attenuated total reflection-Four...

leather artifacts have organic and degradable structure and some historic samples have remained from different historical periods. studies of these scarce specimens have a great importance in the conservation procedure by which the structural study of leather artifact for understanding production process and used materials can be achieved. for this purpose a historic leather bottle has been stu...
