We present a rapid hydrogel polymerization and prototyping microfabrication technique using an optically induced electrokinetics (OEK) chip, which is based on a non-UV hydrogel curing principle. Using this technique, micro-scale high-aspect-ratio three-dimensional polymer features with different geometric sizes can be fabricated within 1–10 min by projecting pre-defined visible light image patt...

Using single-molecule optical-trapping techniques, we examined the force-induced dynamic behavior of a single nucleosome core particle. Our experiments using the DNA construct containing the 601 nucleosome-positioning sequence revealed that the nucleosome unravels in at least two major stages. The first stage, which we attributed to the unraveling of the first DNA wrap around the histone octame...

Abstract Achieving maximum parallel performance on multi-core CPUs and many-core GPUs is a challenging task depending multiple factors. These include, for example, the number granularity of computations or use memories devices. In this paper, we assess those factors by evaluating comparing different parallelizations same problem multiprocessor containing CPU with 40 cores four P100 Pascal archi...

The present paper employs supported ruthenium nanoparticles alongside catalytic quantities of the radical initiator, which are proven to be capable cyclooctene oxidation with green conditions, in absence solvent, air as main oxidant and without sacrificial reductant. examines effects a range initiators how products distributed over time. Furthermore, addresses reaction pathways epoxides allylic...

objectives : marginal adaptation is important for long-term success of full-coverage restorations. the aim of this study was to determine the effect of porcelain firing cycle and different thicknesses of ips e.max core on marginal accuracy of all-ceramic restorations. materials and methods : a standard stainless steel die with 0.8 mm classic chamfer finish line and 10° taper was used in this in...

Wendell Alan Davis University of Texas at Arlington Department of Electrical Engineering Arlington, Texas 76011 Abstract. We present the design, fabrication, and characterization of surface micromachined on-chip 3-D air-core arch-shape solenoid microinductors. Combinations of unique surface micromachining fabrication process techniques, such as deformation of polymeric sacrifical molds and conf...

Three kinds of N-doped mesoporous TiO₂ hollow spheres with different N-doping contents, surface area, and pore size distributions were prepared based on a sol-gel synthesis and combined with a calcination process. Melamine formaldehyde (MF) microspheres have been used as sacrificial template and cetyltrimethyl ammonium bromide (CTAB) or polyvinylpyrrolidone (PVP) was selected as pore-directing ...
