Simple synthesis of highly ordered mesoporous carbon by self-assembly of phenol–formaldehyde and block copolymers under designed aqueous basic/acidic cond... In view of the low reactivity of phenol with formaldehyde under acidic condition in the synthesis of ordered mesoporous carbons, a strategy to...
In this three-protein complex, FeSII mediates an extensive network of interactions with MoFeP and FeP to position their iron–sulphur clusters in catalytically inactive but O2-protected states. The architecture of the FeSII–nitrogenase complex is confirmed by solution studies, which further indicate...
Thus, Ca2+ depletion could potentially change the redox properties as well as substrate and/or protein interactions of the complex, inhibiting catalytic function. The Mn4O5Ca cluster in the S2 state exhibits a characteristic multiline EPR signal centered at g≈ 2 (33) that arises from an S ...
The great importance of the sol–gel process is because of the different characteristics and properties obtained by the synthesis of mixed oxides which are unique. The characteristics of the sol–gel process are well known: the reactions operate at low temperatures obtaining materials with high therm...
The quantitative study of the oxoacidobasic properties of water, in the LiCl−KCl eutectic, was carried out by means of a galvanic cell consisting of a pO 2− indicator electrode (made of a calcia-stabilized zirconia tube filled with a Ni+NiO mixture and an Ag/AgCl reference electrode)...

The neurodegenerative condition known as Parkinson’s disease (PD) is brought on by the depletion of dopaminergic neurons in the basal ganglia, which is the brain region that controls body movement. PD occurs due to many factors, from which one of the ac
To improve the utilization rate of the energy industry and reduce high energy consumption and pollution caused by coal chemical industries in northwestern China, a planning scheme of a wind-coal coupling energy system was developed. This scheme involved the analysis method, evaluation criteria, plannin...

Step 1: Understand Acidic Strength- Acidic strength is determined by the ability of a compound to donate a proton (H⁺). The more easily a compound can donate a proton, the stronger the acid. Step 2: Consider Electronegativity- The electronegativity of the central atom plays a crucial role...
