The prediction of X2B6 monolayers with ultrahigh carrier mobility by Xiuzhi Du, Zhaoming Huang

“…The anisotropic mechanical properties of the X2B6 monolayer is obtained by the Young’s modulus (296–406 N/m) and the Poisson’s ratio (0.36–0.35). Interestingly, the K2B6 and Rb2B6 monolayers demonstrate a metallic band structure, while the Na2B6 monolayer is a semiconductor with an ultra-narrow bandgap only about 0.42 eV. …”

Rhabdomyolysis and Acute Kidney Injury Requiring Dialysis as a Result of Concomitant Use of Atypical Neuroleptics and Synthetic Cannabinoids by Aiyu Zhao, Maybel Tan, Aung Maung, Moro Salifu, Mary Mallappallil

“…The use of quetiapine which is a substrate of the CYP3A4 and is excreted (73%) as urine metabolites may worsen the side effect profiles of both quetiapine and K2. SCBs use should be included in the differential diagnosis of AKI and serum Creatinine Phosphokinase (CPK) level should be monitored. …”

Estimation by a Sorption Technique of the Amorphous Contribution in the Phases Obtained during the Hydrothermal Crystallization of LTL-Type Zeolite by P.N. Joshi, T.H. Kim, K.I. Kim, V.P. Shiralkar

“…Sorption techniques have been employed to estimate the amorphous contribution obtained during the progressive hydrothermal crystallization of the LTL phase from the K 2 O–Al 2 O 3 –SiO 2 –H 2 O system at 423 K. The curve showing the progressive depletion of the amorphous content as a function of the crystallization time exhibited an inverted sigmoidal-type shape indicative of distinct induction and crystallization stages. …”
