Nanocapsules are key components in new technologies related to biomedicine and materials science. However, their long-term fate after use is still largely ignored. We discuss here a sustainable approach where the products of degradation of the nanoparticles play a significant role in their application because they are…
A strong synergistic corrosion inhibition effect was observed when phytate and molybdate were combined and applied onto a AA2024-T3 substrate. pH 5 was found to be the optimum condition as revealed by free corrosion tests in 3.5% NaCl solution with 1 mM phytate and 10 mM molybdate. The inhibition mechanism was explore…
Cationic substitutions in YAG:Ce 3+ enhance the tetragonal field and red-shift the yellow 4f–5d emission.
Soils developed in the alluvium terraces of the River Nile at Khartoum North, Sudan was analyzed in an attempt to classify it as well as to refer them to their origin. Three river terraces comprising nine profiles were selected to cover the physiographic positions. Lack of B horizon and carbonate accumulation were mai…
Photoactive conducting polyaniline films mixed with a conductivity modulation agent consisting of dopant-mimic groups and a photo-induced dipole moment switching group, exhibit a large, fast light-driven conductivity modulation with dual functionality.
Herein, we presented a hitherto unexplored native fern of north eastern India; Diplazium esculentum mediated biogenic fabrication of spherical silver and anisotropic gold nano structured materials.
The interfacial charge phenomenon of MgO/low-density polyethylene (LDPE) and SiO2/LDPE nanocomposites was measured by synchrotron radiation small-angle X-ray scattering. Based on the Porod theory, the Porod curve of SiO2/LDPE nanocomposite shows negative divergence but the LDPE and MgO/LDPE do not, which reveals that…
In recent years, expanded porphyrins have emerged as a promising class of π-conjugated molecules that display unique electronic, optical and conformational properties. Several expanded porphyrins can switch between planar and twisted conformations, which have different photophysical properties. Such a change of topolo…
In this paper, the micro-mechanism in a (1 − x )BaTiO 3 – x Bi(Zn 2/3 Nb 1/3 )O 3 –0.01NaNbO 3 system, benefiting the realization of ultra-wide temperature range stability, was proposed and applied to study the dielectric properties.
Amorphous carbon nitride films with N/C ratios ranging from 2.24 to 3.26 were deposited by reactive sputtering at room temperature on corning glass, silicon, and quartz as substrates. The average chemical composition of the films was obtained from the semiquantitative energy dispersive spectroscopy analysis. Photolumi…
Graphene flakes (<5 layers) are produced by CVD and electrochemical delamination. Isolated graphite without sintering, cu powder with graphene is separated water.
After nanoparticles internalized, active oxaliplatin( ii ) and DMC can be released upon UVA and intracellular stimulation, exhibiting enhanced anti-cancer efficacy.
Variable-valence Tm x Mn1–x S (0 ⩽ x ⩽ 0.15) compounds have been synthesized and their structural, electrical, and thermoelectrical properties have been studied in the temperature range of 80–1100 K. The regions of existence of solid solutions of sulfides Tm x Mn1–x S with the NaCl-type fcc lattice have been determine…
An easy modulation of the pore size of cyanate ester resins allows amount of inserted drug and its release behavior that depend on pore size and host–drug interactions rather than the surface controllable.
Oxidation of the cyclic sulfide group of 3-(2-methylbenzo[b]thienyl)fulgide into the sulfone one affords 3-[1-(2-methyl-1,1-dioxidobenzo[b]thiophen-3-yl)ethylidene]-4-(propan-2-ylidene)dihydrofuran-2,5-dione, a new photochromic fulgide that displays photomodulated fluorescence properties.
A facile method was developed for the doping of graphene nanosheets grown via chemical vapor deposition (CVD) for all graphene-based organic hybrid devices.
The microwave-driven synthesis of a heteropoly blue cluster yields a redox active cluster, [(HPO3)6Mo21O60(H2O)4](8-), templated by six phosphite anions whereby two phosphites template a tri-lucunary {Mo15} Dawson structure, and one templates a {Mo6} ring with two of the three remaining phosphites acting as bridging l…
Ceramics constitute an integral part of highly efficient armours due to their low density, high hardness, strength and stiffness. However, they lack toughness and multi-hit capability. Therefore, zirconia toughened alumina is investigated. The hardness is evaluated using Vickers, Knoop and instrumented indentations, w…
Soot, often referred to as black carbon emitted from diesel engines, is not only a particulate matter pollutant but also a light-absorbing agent that may affect global climate, but can be effectively controlled using a catalytic diesel particulate filter (DPF). A new YBaCo4O7+δ-type oxygen storage material is reported…
This study investigates the parameters that affect the dispersion of polymer grafted mesoscopic iron-oxide rods (FeMRs) in polymer matrices. FeMRs (212 nm long by 36 nm in diameter) are grafted with poly(methyl methacrylate) (PMMA) at three different brush molecular weights: 3.7 kg mol(-1), 32 kg mol(-1), and 160 kg m…
