We have developed a high-pH, pH-shift refolding "Ph-Fold technology", both for academic research and industrial protein drug development applications. Using this technology, we were able to refold some "difficult-to-refold" proteins, some of which are proven important drug targets and protein drug candidates. The tech…
The transport properties (R(T) and R(H) dependences at various values of the transport current in magnetic fields up to 65 kOe) and low-temperature heat capacity in magnetic fields up to 90 kOe of the BaPb0.75Bi0.25O3 superconductor (T C ≈ 11.3 K) are investigated with the goal of clarifying the mechanisms determining…
In this case report, we present a case of deep, partial-thickness, recalcitrant electrical burn ulcer that was healed completely using tissue debridement with topical 50% TCA (Trichloroacetic acid) and application of autologous fibroblasts. To the best of our knowledge, this is the first time that the application of t…
In this chapter, the progress and development of Ge-based photodetector technologies for optical communication applications are discussed. To enable the realization of silicon photonics interconnect solutions, the development of Ge-on-Si hetero-epitaxy process that is compatible with existing CMOS fabrication technolo…
In the present study, we report the synthesis of ZnO nanostructures using the Vapor-Liquid-Solid growth with different metal catalyst by electron beam evaporation method. As grown samples were characterized by means of Field emission scanning electron microscopy (FESEM), Raman spectroscopy and photoluminescence spectr…
Different amounts of Pd, Pt and Pt-Pd alloy nanoparitcles were deposited on mesoporous carbon nanotube microparticles through an easy polyol reduction method. Pt-Pd bimetallic nanoparticles of varied Pt/Pd molar ratios have alloy structures that are identified by XRD, TEM with EDX and XPS. The activities of five diffe…
LiFePO4/Carbon nanocomposites with varying amounts of carbon were synthesized using polyol process without any further heating as a post step. The X-ray diffraction patterns of all samples were indexed on the basis of orthorhombic olivine-type structure. The field emission-TEM images of composites with the amount of 3…
Based on practical experience, the installation for production of metal oxide nanopowders is updated. The method involves evaporation of the target by a pulsed electron beam, condensation of the vapors of the material in a low-pressure gas, and deposition of nanopowders on a cold large-area crystallizer. In a new inst…
The Doppler broadening of annihilation radiation spectra of some single-element materials from the second to the sixth periods measured by the coincidence technique have been compared with the theoretical calculation based on the projector-augmented wave (PAW) method. Having appropriate valence electron configurations…
Damage to an aluminum(III) bis(2-methyl-8-quinolinato)-4-phenylphenolate (BAlq) organic film by direct electron irradiation was investigated. An electron-bombardment system, which can supply a desired amount and energy of electrons, was set up. Changes in the photoluminescence (PL) intensity of the BAlq layer were use…
We present beam solutions of the strongly nonlocal nonlinear Schrödinger equation in left-handed materials (LHMs). Different Laguerre–Gaussian (LG) necklace beams, such as symmetric and asymmetric single layer and multilayer necklace beams are created by the superposition of two single beams with different topological…
It is found that irradiation of SiO 2 layers containing Si nanocrystals with high-energy heavy ions induces profound structural modifications—specifically, the formation of vertically ordered arrays of nanocrystals along the ion tracks. This effect results in substantial changes in the electrical properties (the condu…
In this paper, we describe the structures of several new acid amplifiers and of extreme ultraviolet (EUV) resist formulations prepared from them. We have synthesized and lithographically evaluated eleven new compounds specifically designed for use as acid amplifiers in EUV resists. We make direct comparisions between…
Electron spin resonance microscopy (ESRM) was employed in the evaluation of diffusion characteristics of point defects (E' paramagnetic centers) in amorphous SiO 2 . Samples were subjected to inhomogeneous γ-irradiation creating a heterogeneous distribution of E'-centers in SiO 2 substrates. The samples were measured…
Binding site mapping refers to the computational prediction of the regions on a protein surface that are likely to bind a small molecule with high affinity. The process involves flexibly docking a variety of small molecule probes and finding a consensus site that binds most of those probes. Due to the computational co…
Pesquisas feitas com pó de rocha têm mostrado a potencialidade de alguns resíduos em promover o enriquecimento mineral de solos pobres; prática definida como rochagem do solo. Este trabalho teve como objetivo avaliar o crescimento de mudas de maracujázeiro-amarelo (Passiflora edulis Sims f. flavicarpa Deg.) em respost…
In this paper steel slag is considered as an aggregate which could improve fire resistance of concrete due to the fact that it is a material that occurs at high temperatures. For this purpose, three concrete mixtures were prepared; concrete mixture with dolomite (reference mixture) and one concrete mixture with each o…
In this paper, we describe the superiority of the titanium nitride (TiN) film formed by atomic layer deposition (ALD) using a tetrakis(dimethylamino)titanium (TDMAT) precursor for metal-gate electrodes of planar metal–oxide–semiconductor field-effect transistors (MOSFETs). It was demonstrated that the resistivity of t…
The possibilities of the eddy-current method for quality control of soldering of joints of stator copper windings in electrical machines are studied. The contribution of closed eddy currents, which are induced in inspected joints by an eddy-current transducer and differ in perimeters and location depths of joints, to…
In connection with the ionization equilibrium of an electron-hole plasma in a highly excited semiconductor, the influence of many-particle effects on both the chemical potentials of carriers and the Mott transition of para-excitons in zinc selenide (ZnSe) is investigated over a wide range of temperatures and carrier d…
