Alkali pretreatment is one of the chemical technologies that has been examined on various types lignocellulosic biomass. To gain a better insight into effects potassium-based catalyst pyrolysis behavior with different materials, potassium bicarbonate (KHCO3) and nitrate (KNO3) were used as additives in this study. The experimental parameters which included particle size, heating rate, additive ...

Measurements of DSC, NMR and high-frequency spectroscopy have been done on PEO-H2O and PEO-H2O-HQ mixed systems. DSC measurements show that water molecules contained in PEO are divided roughly into two species: freezable water and non-freezable water. By 1H-NMR measurements, PEO and H2O protons show an absorption peak around 3.6 ppm and 4.5 ppm, respectively. All the PEO-H2O samples containing ...

Solvothermal reactions of the tricarboxylic acid ligand, biphenyl-3,3',5-tricarboxylic acid (H3bpta), and rare earth nitrate (Ln(NO3)3·6H2O) in the presence of KOH or DMF produced eight 1D linear coordination polymers, namely, [La(bpta)(H2O)5·(H2O)3]n (), [Pr(bpta)(H2O)5·(H2O)2.5]n (), [Nd(bpta)(H2O)5·(H2O)1.75]n (), [Sm(bpta)(H2O)5·(H2O)0.5]n () and [Ln(bpta)(DMF)(H2O)3·(H2O)]n [Ln = Eu (), Gd...

We investigated the microscopic solvation of NaBO2 in water by conducting photoelectron spectroscopy and ab initio studies on NaBO2 (H2O)n (n = 0–4) clusters. The vertical detachment energy (VDE) of NaBO2 is estimated to be 1.00 0.08 eV. The photoelectron spectra of NaBO2 (H2O)1 and NaBO2 (H2O)2 are similar to that of bare NaBO2 , except that their VDEs shift to higher electron binding energies...

Super- and sub-critical water treatments have been of interest as novel methods for protein hydrolysis. In the present study, we studied the effect of sub-critical water (Sub-H2O, 300℃, 80 bar) treatment as well as super-critical water (Super-H2O, 400℃, 280 bar) treatment on the physicochemical properties of porcine skin (PS), which has abundant collagen. Porcine skin was subjected to pre-therm...
