The role of nanodiamonds in the reaction photochemical transformation tryptophan presence halogen hydrocarbons has been studied. free a suspension with diamond nanoparticles and hybrid complex them when exposed to UV radiation chloroform is investigated. Data from stationary time-resolved spectroscopic studies show non-radiative transfer electron excitation energy between molecules its photodes...
Improved online techniques for surface profile measurement can be beneficial in high/ultra-precision manufacturing, in terms of enabling manufacture and reducing costs. This paper introduces a spatially dispersed short-coherence interferometer sourced by a super luminescent diode. This technique uses a broadband light source, which is spatially dispersed across a surface using a reflective grat...
Introduction: Nanodiamonds isolated from primitive meteorites contain isotopically ‘normal’ Xe-P3 and components enriched in heavy and light isotopes Xe-HL, exotic Xe-P6. Excesses of Xe from I decay are also observed [1]. We discuss these in the light of data obtained from size-separated Efremovka nanodiamond samples produced at the Vernadsky Institute, Moscow [2]. Results: Excess Xe is present...
Aims. We have carried out a survey of 60 Herbig Ae/Be stars in the 3 micron wavelength region in search for the rare spectral features at 3.43 and 3.53 micron. These features have been attributed to the presence of large, hot, hydrogen-terminated nanodiamonds. Only two Herbig Ae/Be stars, HD 97048 and Elias 3−1 are known to display both these features. Methods. We have obtained medium-resolutio...
In this study, using 45# carbon steel as the substrate, a first experimental analysis was carried out on polarisation behaviour of different component wattage plating solutions in order to determine reasonable content nanodiamond particles nickel/nanodiamond composite solution. Secondly, effect double-pulse forward and reverse duty cycle working time performance then investigated by testing thi...
Nanocellulose can be obtained from low-cost sources and has been extensively studied in the last decades due to its biodegradability, biocompatibility, low weight, large specific surface area, good mechanical optical properties. The nanocellulose properties palette greatly expanded by incorporating different metals, metal oxides or carbon nanomaterials, with formation of multifunctional hybrids...
Intratumor heterogeneity (ITH) contributes to cancer progression and chemoresistance. We sought to comprehensively describe ITH of somatic mutations, copy number, and transcriptomic alterations involving clinically and biologically relevant gene pathways in colorectal cancer (CRC). We performed multiregion, high-depth (384× on average) sequencing of 799 cancer-associated genes in 24 spatially s...
