Studies have shown that biochar amendment could increase soil nutrient availability and crop production, but the contributions of nutrients including nitrogen (N), phosphorus (P), and potassium (K) in the biochar to plant production need to be tested. A pot experiment was conducted to identify the effects of maize str…
Phytochemical investigation of the acetone extract from the roots of Aphanamixis polystachya resulted in isolation of four new tetranortriterpenes (1-4) in addition to one protolimonoid (methyl-1ξ,7R-diacetoxy-23R,25-dihydroxy-20S,24R-21,24-epoxy-3,4-seco-apotirucall-4(28),14(15)-diene-3-oate (5)), five known limonoid…
Structural, vibrational, and dynamical properties of the mono- and mixed-alkali silanides (MSiH 3, where M = K, Rb, Cs, K 0.5 Rb 0.5, K 0.5 Cs 0.5, and Rb 0.5 Cs 0.5 ) were investigated by various neutron experiments, including neutron powder diffraction (NPD), neutron vibrational spectroscopy (NVS), neutron-scatterin…
Rubrene endoperoxide p-xylene (1) has been obtained in crystalline form from recrystallization and purification of the organic semiconductor, rubrene, and for the first time characterized by single-crystal X-ray diffraction methods. 1 is produced by reaction of rubrene with molecular oxygen to create rubrene endoperox…
Nickel and manganese (Ni–Mn) co-doped with tin oxide (Sn(2–(x + y)) NixMnyO2) nanoparticles were synthesised by a sol-gel method. The influence of dopant concentration on prepared samples is investigated by different analytical techniques including X-ray diffraction (XRD), vibrating sample magnetometer, diffuse reflec…
The mechanical properties of a polyurethane-cement hybrid foam are investigated. The hybrid foam, based on the combined, synergic use of rigid polyurethane foam and portland cement, was introduced for application in the building field. Thermal and acoustic insulation properties, water vapor permeability, and the fire…
The lithiation process in TiO 2 -B as a function of Li content x is studied using density functional theory. Considering a variety of possible pathways, we find that stepwise insertion of Li in TiO 2 -B layers, followed by insertion of Li in O layers, is kinetically the most favorable scenario. Diffusion coefficient (…
In different fermentation processes the separation of the products from aqueous solution is an energy-intensive process step, particularly for hydrophilic products like diols. As an alternative to evaporation and distillation, liquid–liquid extraction of these products is often limited by the unfavorable partition beh…
The N-end rule is a conserved protein degradation pathway that relates the metabolic stability of a protein to the identity of its N-terminal residue. Proteins bearing a destabilising N-terminal residue (N-degron) are recognised by specialised components of the pathway (N-recognins) and degraded by cellular proteases.…
The phenomenon of electrical conductivity maxima of molten salts versus temperature during orthobaric (closed-vessel) conditions is further examined via ab initio simulations. Previously, in a study of molten BiCl3, a new theory was offered in which the conductivity falloff at high temperatures is due not to tradition…
Recent studies have demonstrated that nano-patch antennas formed by metallic nanocubes placed on top of a metallic film largely enhance the spontaneous emission rate of quantum emitters due to the confinement of the electromagnetic field in the small nanogap cavity. The popularity of this architecture is, in part, due…
Abstract The influence of surfactant structure on foam properties of internal olefin sulfonate (IOS) and alpha olefin sulfonate (AOS) in aqueous solutions was estimated from measurements of the foamability, foam stability, and foam morphology, as obtained from conductivity and image analyses techniques. It was found t…
Recent progress in nanotechnology enables the production of atomically abrupt interfaces in multilayered junctions, allowing for an increase in the number of transistors in a processor. However, uniform electron transport has not yet been achieved across the entire interfacial area in junctions due to the existence of…
Topological insulators (TIs) are renowned for their exotic topological surface states (TSSs) that reside in the top atomic layers, and hence, detailed knowledge of the surface top atomic layers is of utmost importance. Here we present the remarkable morphology changes of Bi2Te3 surfaces, which have been freshly cleave…
Bi2Se3 is a prominent narrow gap semiconductor with a rhombohedral crystal structure and potential applications in thermoelectric and spintronic technologies. Its electrical conduction is ruled by native point defects inducing an n-type degenerate behavior. Here, we present a first principles study of the point defect…
Single magnetic skyrmion dynamics in chiral magnets with a spatially inhomogeneous Dzyaloshinskii-Moriya interaction (DMI) is considered. Based on the relation between DMI coupling and skyrmion helicity, it is argued that the latter must be included as an extra degree of freedom in the dynamics of skyrmions. An effect…
A set of features computed from the primary amino acid sequence of proteins, is crucial in the process of inducing a machine learning model that is capable of accurately predicting three-dimensional protein structures. Solutions for existing protein structure prediction problems are in need of features that can captur…
Here, we report a promising perovskite solar cell structure based on a modified ZnO-nanorod interfacial structure with improved stability. An organic surface modifier, i.e., [6,6]-phenyl C61butyric acid methyl ester (PCMB), was employed between the perovskite and the ZnO-nanorod arrays to modify the interface conditio…
We have investigated basic mechanisms of concrete corrosion by studying wollastonite in aqueous environments. This well-defined crystalline mineral is well-suited as a model system of calcium–silicate phases, the main constituent of this important building material. A detailed peak-shape analysis of X-ray diffraction…
The size effect of unmodified and graphene nanoparticle modified matrix fibres is experimentally investigated. Neat matrix fibres show a clear size effect of increasing tensile strength with decreasing volume due to a statistical defect distribution. The nanoparticle modified matrix shows no significant size effect. N…
