After gelation, the gels were exchanged with cyclohexane (four times the volume of gel, three times every 4 h) and freeze-dried at a shelf temperature of −7 °C and a pressure < 3 Torr. The formulations of the PUR-PIR aerogels based on the POL, HPE, and RES polyol ...
The parameters of SSD have been optimized to reproduce the density of water as well as other structural, thermodynamic, dielectric, and dynamic properties at room temperature and 1 atm. Remarkably, this simple model is able to reproduce the anomalous temperature dependence of the density using ...
Following its synthesis, an oligonucleotide is dissolved in 1.5mL of water. You dilute 50μL of the oligonucleotide into a total volume of 1000μL and read the absorbance of the diluted sample at 260nm. AnA260of 0.264 is obtained. How many OD units are present in the 1.5mL of oligonucleo...
where Dens is the urban land density of a ring. S is the total land area in a ring. Surban land and Swater are the areas of built-up areas and water bodies in a ring, respectively. The nighttime light intensity in concentric rings is defined as the ratio of total digital number value...

At room temperature results showed no measurable deactivation effect on catalyst performance in the presence of CO as typically seen for Pt-containing catalysts. Hence, probing active sites under RDE condition using CO has not been a viable strategy to probe this type of NPMCs. In the present ...
