Surface-enhanced Raman spectroscopy (SERS) has enormous potential for a range of applications where high sensitivity needs to be combined with good discrimination between molecular targets. However, the SERS technique has trouble finding its industrial development, as was the case with the surface plasmon resonance te…
Inlay yarn and laid-in stitches as important technical knitting elements have been commonly applied in the structural design and pressure control of compression textiles for certain healthcare and therapeutic purposes. In this study, complex weft laid-in stitches design changed the configurations of the studied elasti…
Gelatin nanoparticles coated with Cathepsin D-specific peptides were developed as a vehicle for the targeted delivery of the cancer drug doxorubicin (DOX) to treat breast malignancy. Cathepsin D, a breast cancer cell secretion enzyme, triggered the release of DOX by digesting the protective peptide-coating layer of na…
Abstract Paratacamite-(Mg) (IMA 2013-014), Cu 3 (Mg, Cu)Cl2(OH) 6 , is the new Mg-analogue of paratacamite. It was found near the village of Cuya in the Camarones Valley, Arica Province, Chile. The mineral is a supergene secondary phase occurring in association with anhydrite, atacamite, chalcopyrite, copiapite, dolom…
Gas-insulated switchgear (GIS) has inherent internal defects that may result in partial discharge (PD) and the eventual development of equipment faults. PD in GIS can lead to the generation of multiple decomposition products of SF6, and the detection and analysis of these decomposition products is important for fault…
CuGaS2 (CGS) nanoplates were successfully synthesized by one-pot thermolysis of a mixture solution of CuCl, GaCl3, and 1-dodecanethiol in noncoordinating solvent 1-octadecene. Their morphology, crystalline phase, and composition were characterized by scanning electron microscopy (SEM), transmission electron microscopy…
Globular clusters of natural shungite carbon appear to be aggregates formed by nonplanar graphenes through stable aqueous dispersion. The ability of the clusters for spontaneous disaggregation in water and stabilization without surfactants was demonstrated. Due to their size and curvature, shungite graphenes contribut…
Cyclohexylamine, morphine, ethanolamine, propiolic alcohol, seventeen alkenyl amide ethyl imidazoline, water depolymerization malaya acid anhydride, etc were chosen as the raw material of corrosion scale inhibitor in view of corrosion scaling reason and characteristic of blast furnace top gas pressure recovery turbine…
By classical molecular dynamics, a series of solutions in the ternary water-lithium nitrate-calcium nitrate system is simulated. The radial distribution functions for different atom pairs are calculated, the coordination numbers are estimated, and the pattern of change of their first solvation shell composition with a…
Fabrication of graphene nanoribbon arrays by substrate-controlled cutting of graphene during metal-assisted etching is demonstrated by Hiroki Ago and co-workers on page 6562. The proposed method allows for large-area production of highly dense arrays of aligned nanoribbons from a single graphene film. This is expected…
Abstract The poly(vinyl alcohol)/silica nano-composities hybrid membranes were prepared by co-hydrolysis and co-condensation of γ-glycidyloxypropyl trimethoxysilane (GPTMS) and tetraethoxysilane (TEOS) in poly(vinyl alcohol)(PVA) aqueous solution. The mechanical properties of hybrid membranes was studied, the result i…
In this research, mesoporous silica was applied as the host of corrosion inhibitor (molybdate). The loaded mesoporous silica was dispersed in an epoxy matrix. The composite was then coated on the mild steel plate. Results showed that the corrosion resistance of the scratched epoxy/mesoporous silica loaded by molybdate…
The microstructures and mechanical properties of the Cu-17Ni-3Al-X alloy hot-extruded at different extrusion ratios were investigated by tensile and hardness testing, optical microscope (OM) and scanning electronic microscope.The results show that the dynamic re-crystallization occurs when the extrusion ratio λ increa…
Abstract Dervillite, As 2 AsS2, has been found in a sample from the Lengenbach quarry in the Binn Valley, Valais, Switzerland. It occurs as very rare crystals up to 200 μm across on jordanite. Dervillite is opaque with a metallic lustre and shows a dark brown streak. The structure is monoclinic, space group P c , with…
The foam was prepared by mixing the polyols, isocyanate and carbonnanotubes (CNTs) at 1000 rpm speed. The different content of the CNTs are varies from 0 3 (0, 0.5, 1.5, 2.0, 2.5, 3.0) percent by weight. The foam sandwich was prepared by using hand lay-up method with epoxy and hardener as the adhesive to bind the surf…
The article presents the results of tests connected with influence of strain parameters on the susceptibility to hot working of magnesium lithium alloys with lithium content of 7.5% mass. Plasticity tests were conducted in compression test from room temperature up to 400°C with strain rate of 0.1s -1 . Conducted tests…
Excessive exposure to noise is harmful for human health. Noise-induced hearing loss is one prevalent disorder resulted from above case. One root solution that converts the unnecessary sound waves to dissipated heat energy is acoustic absorption panel. Previous studies had looked upon potential sound-absorbing resource…
The stress relaxation modulus E(t) is one of the most important properties of viscoelastic materials such as solid propellant, and it is used to define the viscoelastic behavior based on the influence of time and temperature. In this paper, stress relaxation tests are conducted under constant strain 2% for 600 seconds…
Abstract This paper has described a method to obtain the molecular weight distribution (MWD) of polymeric materials from their rheological data. The method has been developed for linear polymers with log normal molecular weight distribution. The rheological data required to obtain the molecular weight distribution are…
To investigate how the number of charged groups affects the refinability of pulp, different levels of fibre charge were introduced to fully bleached softwood kraft pulp by bulk carboxymethylation. ...
