Thus, this was only addressed on a basic level by preventing direct sunlight from heating the HAL-Ms. Prior to the start of the experiment, we waterlogged the HAL-Ms until excess water was discharged from the bottom of the vessels, but we did not reach the calculated FC (Fig. 5). ...
which in turn lead to the generation of porous structures with thin 2D porous carbon instead of dense and compact structures. We therefore studied the heating rate
These slow heating rates (up to 4 °C/min) were adopted so as to observe the various thermodynamic reaction processes clearly15. When conducting DSC experiments, the sample masses can affect the calorimetry results49: if the sample mass is too high and the heating rate is too fast, self...
A three-electrode cell with a Pt working electrode, a Pt counter electrode, and an Ag/AgCl in 4 M KCl reference electrode was used for the electrochemical co-deposition of ZnO and Co(OH)2 by nitrate reduction at 60 °C. During the nitrate reduction, OH− was generated at the working...
We found a positive association between SOIL and DBP. SOIL containing metal elements and silica are suspended in the air due to mechanical movements (transportation and human activity). Elevated DBP have been associated with increased concentrations of lead (Pb) and nickel (Ni) in PM2.5 (Dai et...
During the rapid CTS process (with a heating rate of 104 °C/s), the decomposition of metal precursors and ligands will instantly generate a large amount of vigorously diffused gases that act as pore-forming agents, which in turn lead to the generation of porous structures with thin 2D po...
Using an oxyacetylene torch, a welder can identify various metals by studying how the puddle of slag and molten metal looks and how fast the metal melts during heating. When a sharp corner of a white metal part is heated, the rate of melting can be an indication of its identity. ...
We added Calciferol to the therapy protocol at the 7th day when the blood phosphor decreased to normal levels. The owners asked us not to operate and to wait but as usual despide the cage rest after a couple of days the fragments geometry get worse and the healing would lead to malunion...
The support was impregnated with a solution of tetraammineplatinum (II) nitrate (99.995%, Sigma Aldrich) dissolved in ultrapure (MilliQ®) water (incipient wetness impregnation, Pt loading of 2 wt. %). Subsequently the material was calcined for 5 h (heating rate 10 °C min−1) ...
3 indicate the presence of O2− species as well as OH− species, whereas the N1s XP spectra reveal the presence of small amounts of N impurities, intuitively from the Fe nitrate precursor, present at a binding energy typical for Fe–N bonds19. Additionally, pyridine-like C-N species14...
