Threedifferent methods were used to prepare CuY catalysts, whichplay an important role in Cu loading and ion-exchange level duringthe oxidative carbonylation of ethanol to synthesize diethyl carbonate.Of the prepared CuY catalysts, those synthesized by the ammonia evaporationmethod exhibited a ...
which Wang et al. (2018a) used to remove lead ions (Pb2+) from aqueous solutions. To prepare the biosorbent, the plant material was processed similarly to the biosorbents discussed previously. A modified biosorbent was created by soaking
Consequently, laminarin is often used as a substrate to evaluate the fungal cell wall-active enzymes4. Glucanases are important in biological pest control, bioremediation, food industry, production of fungal spheroplast and to produce ethanol5,6,7,8,9. Further, β-glucanases, especially the ones...
3). A total of 13,566 cells (64,000 temporal points) were reconstructed (1 million temporal points) to obtain high-resolution single-cell mass spectra. Analysis of 3D MSI data Data preparation To prepare for data analysis, we first determined the peak centroids on the average mass spectra ...
Cerium nitrate hexahydrate was dissolved in ddH2O and precipitated by the dropwise addition of the obtained solution to the ammonia solution. Water-soluble species were then removed by deionized water washing. Ethanol was then used to remove water and disrupt hydrogen bonded networks between water ...
The released enzyme was purified with an Amylose Resin column to retain MBP protein. Western blot analysis The purified PCPEL2 was used to prepare antibody in New Zealand white rabbits [30]. The antibody preparation, purification and antiserum titer determination were done as previously described [...
The kits may further include a suitably aliquoted composition of the probes and/or primers, whether labeled or unlabeled, as may be used to prepare a standard curve for a detection assay. The components of the kits may be packaged either in aqueous media or in lyophilized form. The container...
they tend to fuse to achieve a minimal length to finally form a close system and both, large and small unilamellar vesicles, can be obtained. The main disadvantages related to this method are the removal of residual ethanol, especially after azeotrope formation, low encapsulation efficiency and th...
Face-to-face transfer Commercial Au holey carbon grids (Quantifoil, Au 300 or 200 mesh R1.2/1.3) were used to prepare the graphene grids. Note that the grids with copper bars should be avoided because the copper bars can be etched by the (NH4)2S2O8aqueous solution. To transfer UFG from...
Standard methods to assess the durability of vitrified radioactive waste were first developed in the 1980’s and, over the last 40 years, have evolved to yield a range of responses depending on experimental conditions and glass composition. Mechanistic understanding of glass dissolution has progressed...
