The diatom succession and sedimentation during 2011 in a subtropical, deep alpine lake (Lugu Hu, Southwest China) were studied. The seasonal patterns in diatom assemblages were related to light, nutrient availability, and thermal regime. Peaks in the concentration of the planktonic diatoms (Asterionella formosa and Cy…
BACKGROUND: Microbial polyesters, also known as polyhydroxyalkanoates (PHAs), closely resemble physical and mechanical features of petroleum derived plastics. Recombinant Escherichia coli strains are being used in industrial production of PHAs in Stirred Tank Bioreactors (STRs). However, use of Air-Lift Reactors (ALRs…
Extensive first-principles calculations suggest that inverse Heusler compounds , , , and are the candidates to achieve fully compensated ferrimagnetic spin gapless semiconductors. It is shown that only the holes can be 100% spin polarized in , while both the excited electrons and the holes around the Fermi level 100%…
Abstract Plastic deformation processes are among the most demanding processes in manufacturing because they lead to different microstructure features in the materials produced. Various dislocation patterns can be induced by plastic strain under different conditions. A serrated yielding/jerky flow in some dilute alloys…
The present competition of graphene electronics demands an efficient route which produces high quality and large area graphene. Chemical vapour deposition technique, where hydrocarbons dissociate in to active carbon species and form graphene layer on the desired metal catalyst via nucleation is considered as the most…
Thin films of copper oxide were prepared by chemical bath deposition (CBD) method on substrates of glasses by Alternate immersions method (AI) at room temperature for 20 second using heated liquid of sodium hydroxide up to 70° and copper thiosulfate complex. The substrates were annealed at different temperatures (200-…
This paper established a mathematic model of segmented thermoelectric generator (TEG) based on low-temperature thermoelectric material bismuth telluride and medium-temperature thermoelectric material skutterudite. The performance of segmented TEG and traditional TEG has been compared using this model under different c…
Characterization and experimental modelling were employed for investigating prospects of Phyllanthus muellerianus as eco-friendly/sustainable material for reducing concrete steel-reinforcement corrosion in industrial/microbial environment. Atomic Absorption Spectroscopy/Fourier Transform Infra Red Spectroscopy of the…
OBJECTIVE: To assess the retention of gadolinium (Gd) in skin, liver, and bone following gadodiamide or gadoteric acid administration. METHODS: Gd was measured in skin, liver and femur bone in female rats 10 weeks after administration of 17.5 mmol Gd/kg over 5 days of Gd agents. Rat skin microscopy, energy filtering t…
Tin doped zinc oxide films were prepared on glass substrates by spray pyrolysis. The effect of Sn content on microstructures and optoelectronic properties of the films were investigated by X-ray diffraction, UV–visible spectrophotometer and Hall effect. The results show that all the films are polycrystalline with (002…
Positively surface-charged poly(lactide-co-glycolide) (PLGA)/Eudragit RL nanoparticles (NPs) were designed to increase retention time and sustain release profile in joints after intra-articular injection, by forming micrometer-sized electrostatic aggregates with hyaluronic acid, an endogenous anionic polysaccharide fo…
Poly(vinylpyrrolidone)-capped silver nano-hexapods (AgNHs) have been prepared by chemical reduction method using ethylene glycol as a reducing agent, for the study of their structural and elastic properties. HRTEM study reveals that the prepared nanocrystals are hexapod in shape with an average size of approximately 5…
This paper presents the investigation of power generation using the combination of heat pipes and thermo-electric generators. A majority of thermal energy in the industry is dissipated as waste heat to the environment. This waste heat can be utilized further for power generation. The related problems of global warming…
Realgar (AS4S4) has been used in traditional medicines for malignancy, but the poor water solubility is still a major hindrance to its clinical use. Realgar quantum dots (RQDs) were therefore synthesized with improved water solubility and bioavailability. Human endometrial cancer JEC cells were exposed to various conc…
Liquid-infused patterned surfaces offer a promising new platform for generating omniphobic surface coatings. However, the liquid infused in these surfaces is susceptible to shear-driven dewetting. Recent work [Wexler et al., “Shear-driven failure of liquid-infused surfaces,” Phys. Rev. Lett. 114, 168301 (2015)] has sh…
The thermal characteristics of the construction materials currently used in the Saharan regions of Algeria are not adapted to its climate conditions. The climate in these regions is characterized by a hot and dry climate in summer and very fresh in winter. The aim of this research is to make some bricks with good ther…
Field-effect transistor (FET) sensors based on reduced graphene oxide (rGO) for detecting chemical species provide a number of distinct advantages, such as ultra-sensitivity, label-free, and real-time response. However, without a passivation layer, channel materials directly exposed to an ionic solution could generate…
Organically modified montimorillonite nanoclay was added to the epoxy and E-glass-epoxy composites. The influence of nanoclay content (varied between 0 to 5wt %) on the relative crosslink density and the fracture toughness of the epoxy matrix was studied. Differential scanning calorimetry (DSC) indicated that the amin…
The aim of the work reported here was to develop lipid-coated multifunctional nanocomposites composed of drugs and nanoparticles for use in cancer therapy. We incorporated thermosensitive phospholipids onto the surface of anisotropic gold nanoparticles (AuNPs) to further enhance drug delivery, with possible additional…
Membrane protein structural biology has benefitted tremendously from access to micro-focus crystallography at synchrotron radiation sources. X-ray free electron lasers (XFELs) are linear accelerator driven X-ray sources that deliver a jump in peak X-ray brilliance of nine orders of magnitude and represent a disruptive…
