Based on two criteria, the tightness of packing of myosin rods within the backbone of the filament and the degree of order of the myosin heads, thick filaments isolated from a control group of rat hearts had three different structures. Two of the structures of thick filaments had ordered myosin heads and were distinguishable from each other by the difference in tightness of packing of the myosi...
BACKGROUND Engineered nanomaterials (ENMs) have potential benefits, but they also present safety concerns for human health. Interlaboratory studies in rodents using standardized protocols are needed to assess ENM toxicity. METHODS Four laboratories evaluated lung responses in C57BL/6 mice to ENMs delivered by oropharyngeal aspiration (OPA), and three labs evaluated Sprague-Dawley (SD) or Fish...
The purpose of this study was to investigate the antimicrobial properties of a conventionalpoly methyl methacrylate (PMMA) modified with hydrothermally synthesised titaniumdioxide nanotubes (TNTs). Minimum inhibitory concentration (MIC), minimum bactericidalconcentration (MBC), and minimum fungicidal concentrations (MFC) for planktonic cellsof the TiO2 nanotubes solution against Lactobacillus a...
We report the growth of ultralong (>10 cm) multi-walled and single-walled carbon nanotubes such that the length is limited by the size of the furnace rather than by the termination of growth. The disturbance of microscale laminar flows results in disordered or shorter growth of carbon nanotubes. By downsizing reaction pipes, reaction gas flows are stabilized with low Reynolds numbers. In this w...
Developing effective heterogeneous metal catalysts with high selectivity and satisfactory activity for chemoselective hydrogenation of alkyne to alkene is of great importance in the chemical industry. Herein, we report our efforts to fabricate TiO2-supported Pd catalysts by a photodeposition method at room temperature for phenylacetylene semihydrogenation to styrene. The resulting Pd/TiO2 catal...
We report an underpotential deposition (UPD) route of Cu2ZnSnS4/TiO2 nanotube arrays (TiO2-NTAs) in which the Kesterite (Cu2ZnSnS4) was employed as a sensitizer to enhance photoconversion efficiency TiO2-NTAs. Cu2ZnSnS4 simultaneously coated on TiO2-NTAs by depositing its constituent metals from precursor ions via electrochemical atomic layer (EC-ALD) and subsequent annealing. The detailed synt...
A flexible and mild fabricating protocol, i.e., stepwise reduction in situ loading route, is proposed to modulate ordered growing dispersive depositing of [email protected] bimetal layered nanostructure on titanium dioxide nanotubes (TiO2-NTs) via reasonably regulating addition sequence dosage for the reactants additives. Comprehensive characterizations demonstrate that most Cu core-Pt shell na...
