Comparing the results of single-crystal X-ray and NMR experiments, the V-V ion in the undissociated [VO(O-2)(2)(mpa)](-) in solution displays a similar seven-coordinate distorted pentagonal bipyramidal geometry with the solid-state crystal. The catalytic activity of the 1 in the oxidative...
Question: What is the Lewis structure for H2O? The Lewis Dot Structure for H2O: The Lewis dot structure for any molecule can be found by following a general set of rules consisting of 5, or sometimes 6 steps. These structures facilitate proper description of bonding in terms of available val...
Terminal alkenes are produced from a range of saturated fatty acids (C12–C20), and stopped-flow spectroscopy indicates a rapid reaction between peroxide and fatty acid-bound OleTJE (167 s−1 at 200 μm H2O2). Surprisingly, the active site is highly similar in structure to the related ...
In the ARH3–ADPR–Mg2+ complex, two Mg2+ ions (MgA and MgB) have an octahedral coordination geometry and are fully occupied with only 3.3-Å intermetal distance (3.8 Å in the unliganded ARH3 structure). They are bridged by the bidentate carboxyl group of Asp316 as well as by the...
high consumption of raw materials, and serious environmental pollution. The direct oxidation of benzene into phenol by H2O2is one of the challenging subjects in the field of green chemistry4,5,6, which is of great industrial and social significance. Therefore, the development of novel and efficien...
This study addresses the environmental risks associated with the accumulation of keratin waste from poultry, which is resistant to conventional protein degradation methods. To tackle this issue, microbial keratinases have emerged as promising tools for t
The turbulent combustion model is extended to nonadiabatic flame by introducing additional variable for the transport equation of enthalpy and radiative heat loss is calculated using a local, geometry independent model. The predictive capability of the RPV combustion model has been validated against the...
The present disclosure provides a method for forming a semiconductor device that includes forming a replacement gate structure overlying a channel region of a substrate. A mandrel dielectric layer is
What is the molecular geometry of SiOH2? Draw its Lewis structure and determine its bond angles.What is the molecular structure of [PCl_6]^-, and what is the bond angle?Which of the following molecules can form hydrogen bonds with other molecules of the ...
A careful NMR investigation of the conformational behaviour in these systems was relevant. It has been found that the dicarbonylic group in compounds 1–5 has a trans geometry, stabilized by intramolecular hydrogen bonding and that they possess a C2 axis. Compounds 1 and 2 are planar and compo...
