Hollow carbon-based nanostructures (HCNs) have found broad applications in various fields, particularly rechargeable batteries. However, the syntheses of HCNs usually rely on template methods, which are time-consuming, low-yield, and environmentally detrimental. Metal-organic frameworks (MOFs), constructed by organic ligands inorganic metal nodes, been identified as effect platforms for prepari...

In vitro transcription studies with a trp leader DNA template derived from a double deletion mutant of Serratia marcescens revealed that the transcription complex pauses synthesis of part of the RNA antiterminator, structure 2:3. Pausing was enhanced by NusA protein and was dependent on the concentration of UTP in the transcription reaction mixture. A weak antiterminator pause also was detected...

One-step facile synthesis of monoporous polymer microspheres via microwave-controlled dispersion polymerization is introduced. This template-free method employing the dispersion polymerization of styrene under microwave irradiation induces directly the formation of uniform monoporous polymer microspheres, with controllable morphologies and sizes, which can be tuned by simply adjusting parameter...

Auxin treatment of aged pea stems (Pisum sativum L. var. Alaska) caused a decrease in monosomes (especially free monosomes) and an increase in polysomes (especially membrane-bound polysomes). These effects were not duplicated by gibberellic acid or benzyladenine. These auxin-stimulated shifts in polysome distribution commenced at least 9 hours before significant growth took place. It is suggest...

The replicase activity of rotavirus open cores has been used to study the synthesis of (-) strand RNA from viral (+) strand RNA in a cell-free replication system. The last 7 nt of the (+) strand RNA, 5'-UGUGACC-3', are highly conserved and are necessary for efficient (-) strand synthesis in vitro. Characterization of the cell-free replication system revealed that the addition of NaCl inhibited ...

Several samples of mesoporous silica were prepared via sol-gel chemistry in the presence of CTAB as template with variation of stirring intensity and aging time, ratios of CTAB/SiO2 and NH4OH/H2O in synthesis mixture. Effects of aging temperature, hydrothermal treatment and ter-Butanol addition to the synthesis mixture on the textural properties of obtained samples were also studied. Results of...
