A new method to solidify Cr(VI), Cr(III), and Ni(II) simultaneously by using a glass-ceramics microstructure was used. For a crystallization temperature of 870 degrees C, base glass (air cooling) with a mass ratio of CaO / SiO2 (R(C/S)) of 6/16, 10/16 precipitated a CaNiSi2O6 crystalline phase that could not solidify Ni(II) stably, and with an incr...

Lead halide perovskites are among the most exciting classes of optoelectronic materials due to their unique ability to form high‐quality crystals with tunable bandgaps in the visible and near‐infrared using simple solution precipitation reactions. This facile crystallization is driven by their ionic nature; just as with other salts, it is challengi...
Two-dimensional (2D) single crystal transition metal nitrides (TMNs) with exposed active crystal planes have great value for fundamental science and technological applications. However, it is still a great challenge to synthesize the non-layer crystal structured 2D single crystal TMNs, e.g. the face-centered cubic (FCC) 2D single crystal TiN, which...

The precipitation of CaCO3 and its kinetics for the CaCl2-CO2-Mg(OH)(2)-H2O system were systematically studied to develop a novel process for eliminating solid and liquid waste from the Solvay soda process. The effects of operating conditions including temperature, CaCl2 concentration, flow rate of CO2, and stirring speed on the reaction kinetics w...

Saline alkaline lakes that precipitate sodium carbonate evaporites are most common in volcanic terrains in semi‐arid environments. Processes that lead to trona precipitation are poorly understood compared to those in sulphate‐dominated and chloride‐dominated lake brines. Nasikie Engida (Little Magadi) in the southern Kenya Rift shows the initial st...
beta-Glucan phosphorylases are carbohydrate-active enzymes that catalyze the reversible degradation of beta-linked glucose polymers, with outstanding potential for the biocatalytic bottom-up synthesis of beta-glucans as major bioactive compounds. Their preference for sugar phosphates (rather than nucleotide sugars) as donor substrates further under...
We prepared bulk samples of supercooled liquid water under pressure by isochoric heating of high-density amorphous ice to temperatures of 205 +/- 10 kelvin, using an infrared femtosecond laser. Because the sample density is preserved during the ultrafast heating, we could estimate an initial internal pressure of 2.5 to 3.5 kilobar in the high-densi...
