Recent studies have revealed that Escherichia coli possesses an essential targeting system for integral membrane proteins, similar to the mammalian signal recognition particle (SRP) machinery. One essential protein in this system is FtsY, a homologue of the alpha-subunit of the mammalian SRP-receptor (SR-alpha). However, E. coli does not possess a close homologue of the integral membrane protei...
statement of problem: in some clinical situations, repair of composite restorations is treatment of choice. improving the bond strength between one new and old composite usually requires increased surface roughness to promote mechanical interlocking since chemical bonding might not be adequate. similarly, the treatment of a laboratory fabricated resin composite restoration involves the same pro...
Lanthanides are vital components in lighting, imaging technologies and future quantum memory applications owing to their narrow optical transitions and long spin coherence times. Recently, diamond has become a pre-eminent platform for the realisation of many experiments in quantum information science. Here we demonstrate a promising approach to incorporate Eu ions into diamond, providing a mean...
In this study, diamond films are deposited by using hot filament chemical vapor deposition (HFCVD), Nanocrystalline diamond (NCD) coated cemented tungsten carbide (WC-Co) milling tools are characterized, compared with microcrystalline diamond (MCD) and composite diamond coated ones, in terms of morphology with field emission scanning electron microscope (FESEM). Moreover, the diamond coated too...
This paper shows the manufacture route of the bronze 4% weight diamond composite rope for direct application as diamond wires, and linear saws in the slabbing and cutting of dimension stones. This route consists of powder mix compaction, sintering and rotary forging techniques. Tensile tests were performed, reaching an ultimate tensile strength of 230MPa for the diameter of ∅=1.84mm. Scanning e...
To analyze the local structure and/or chemical states of boron atoms in boron-doped diamond, which can be synthesized by the microwave plasma-assisted chemical vapor deposition method (CVD-B-diamond) and the temperature gradient method at high pressure and high temperature (HPT-B-diamond), we measured the soft X-ray emission spectra in the CK and BK regions of B-diamonds using synchrotron radia...
We obtain certain simple sufficiency criteria for a class of p-valent alpha convex functions. Many known results appear as special consequences of our work. Some applications of our work to the generalized integral operator are also given.
In recent years, nanomachining has attracted increasing attention in advanced manufacturing science and technologies as a value-added processes to control material structures, components, devices, and nanoscale systems. To make sub-micro patterns on these products, micro/nanoscale single-crystal diamond cutting tools are essential. Popular non-contact methods for the macro/micro processing of d...
