Cation–π interactions are considered to be among the most important strong noncovalent in aqueous solutions and as regulators of various biological phenomena, including adhesion, signal transduction, liquid–liquid phase separation (LLPS). Despite their significant roles, cation–π environments not systematically experimentally understood. Here, we directly examined between cationic aromatic moie...

The Friedel-Crafts alkylation constitutes one of the most important reactions for formation carbon-carbon bonds. Here, we report using squalene-hopene cyclases, which provides a biological alternative to traditional strategy. cyclase from Alicyclobacillus acidocaldarius (AacSHC) and variants have been demonstrated broad substrate reaction scope, making them valuable potential applications in bi...

Abstract. Glyoxal (CHOCHO) and methylglyoxal (CH3C(O)CHO) are well-known components of atmospheric particles their properties can impact chemistry cloud formation. To get information on hydration states in aqueous solutions how they affected by the addition inorganic salts (sodium chloride (NaCl) sodium sulfate (Na2SO4)), we applied carbon oxygen K-edge X-ray absorption spectroscopy (XAS) trans...

In the recent years, the biophysical properties and presumed physiological role of aquaporins (AQPs) have been expanded to specialized cells where water and solute exchange are crucial traits. Complex but unique processes such as stomatal movement or pollen hydration and germination have been addressed not only by identifying the specific AQP involved but also by studying how these proteins int...

The major hydraulic phase in all the calcium aluminate cements including ciment fondue is CA (CaAl2O4). Once hydrated, it starts to form the hexagonal crystals of CAH10 and C2AH8 that depending on the time and temperature of hydration convert to the cubic crystals of C3AH6 and AH3. The nature, sequence, ...

Enhanced dynamical fluctuations of RNAs, facilitated by a network of water molecules with strong interactions with RNA, are suspected to be critical in their ability to respond to a variety of cellular signals. Using atomically detailed molecular dynamics simulations at various temperatures of purine (adenine) and preQ1 sensing riboswitch aptamers, which control gene expression by sensing and b...

Unsurprisingly, education research shows that students engage better when an instructional storyline begins with a surprising claim about topic important in their own lives. Today, everyone understands the importance of immune response to lives, and most find it paradoxical be told some bonds strengthen under applied pulling force. So recent discovery catch-bond behavior T-cell activation is ve...

in this study the effect of nano meter size zro2 particles on the microstructure, densification and hydration resistance of magnesite –dolomite refractories was investigated. 0, 2, 4, 6 and 8 wt. % zro2 particles that were added to magnesite –dolomite refractories containing 35 wt. % cao. the hydration resistance was measured by change in the weight of specimens after 72 h at 25℃ and 95% relati...
