Reversible CO2 capture and release under ambient conditions is crucial for energy-efficient carbon storage. Here, we report the pressure swing crystallization of in a single-crystalline guanidinium sulfate-based clathrate salt practical 52 kPa 298 K, with high density (0.252 g cm−3) capacity (17 wt %). The captured released as pure stream through moderate means or temperature stimulation, all w...

ZIF-94 is a zeolitic imidazolate framework with the same SOD type topology than ZIF-8 but an aldehyde group functionalized organic ligand. This turns less thermally stable interesting properties of water and carbon dioxide adsorption, making former material highly suitable for capture technologies. In this work, alternative procedure synthesis was developed based on use NaOH as deprotonator. Be...

L-Tyrosine and L-Dopa are the precursors in the biological synthesis of amine neurotransmitters. On the other hand, phenylalanine as an aromatic amino acid (AAA) is a precursor in the synthesis of L-Tyrosine and L-Dopa. For some substrates such as amino acids, resolution by the formation of diastereomers offers an attractive alternative. Among different methods in this case, crystallization-ind...

The multi-component solid form of febuxostat (FEB) with p-toluenesulfonic acid was synthesized by solvent-drop grinding and cooling-evaporative crystallization characterized powder X-ray diffraction (XRPD), thermogravimetry (TGA), differential scanning calorimetry (DSC), infrared spectroscopy (FT-IR). stable after exposure at elevated temperature relative humidity dissolution measurements revea...

The Nagqu area is in the northern part of Qinghai–Tibet Plateau, and its average altitude above 4000 m. Due to area’s high altitude, there relatively little information about lakes. Therefore, supplement basic lakes area, this study collected surface water samples from 12 lakes, including Gangtang Co, Pusaier Guojialin Dagze Yangnapeng Bankog Dangqung Chaxiabu Angdar Bengze Guogen Yibug Caka Ju...
