Background: Electrospinning is a modest and real tactic to harvest nanofiber membranes from micrometers to nanometers scale diameters, are useful in modern nanotechnology like biomedical, filtration, defense, catalysis, sensor and energy applications. Wound healing practice is deliberated a constant morphological modi…
Polyurethane foam-based sandwich structures were developed for radar absorbing properties together with load bearing capability. The sandwich construction of radar absorbing structure comprised glass fiber epoxy matrix composite containing carbon black as front face skin, carbon fiber epoxy matrix composite as back fa…
An intermediate phase LaMg 2 NiH 4.6 found for the hydrogenation reaction of the ternary intermetallic compound LaMg 2 Ni to the complex transition-metal hydride LaMg 2 NiH 7 has been investigated experimentally and theoretically. It is known that this reaction induces only minor rearrangement of the host metal atoms,…
The inclusion complex of thermoplastic polyurethane (TPU) and β-cyclodextrins (β-CD) with high TPU contents has been synthesized. The channel structure with large amount of uncovered TPU was confirmed by wide-angle X-ray diffraction (WAXD). High performance poly(oxymethylene) (POM) alloys were fabricated by simply mel…
Metallic nanostructures are often used to enhance photoluminescence of nanomaterials based on local field enhancement with plasmons at metal surfaces. Here upconversion luminescence (UCL) enhancement of submicrometer-size NaGd0.3 Yb0.7 F4 :Er particles in cap-like metal cavities, formed by deposition of a silver film…
Abstract The thermal properties and thermoelectric performance of one-dimensional armchair and zigzag γ -graphyne nanoribbons ( γ -GYNRs) are theoretically investigated in the present study. We found that the pristine γ -GYNRs hold lower phononic thermal conductance and better figure of merit ( ZT ) than graphene nano…
Hybrid sisal fibers (HSFs) were made by mixing untreated sisal fibers with alkali-treated sisal fibers (ASFs), and the HSFs were blended with polylactic acid (PLA) matrix. Then the diatomite particles were added into the PLA/HSFs composite to make PLA/HSFs/diatomite composite. The effect of these two fillers on mechan…
We present a systematic study of the coercive field of CoFe2O4–SiO2 nanocomposites. The samples were prepared via the sol-gel method by using the Tetraethyl Orthosilicate as starting reagent. Results of X-ray diffraction, transmission electron microscopy, and X-ray fluorescence confirm the dispersion of the magnetic n…
The easy and effective capture of a single protein from a complex mixture is of great significance in proteomics and diagnostics. However, adsorbing nanomaterials are commonly decorated with specific ligands through a complicated and arduous process. Fe3 O4 /carboxymethylated chitosan (Fe3 O4 /CMCS) nanoclusters are d…
SUMMARY A flammability evaluation tool that requires only milligram size sample is very attractive for plastic material development and quality control. One such instrument that has gained importance in recent years is the microscale combustion calorimeter (MCC). In this study, a novel application using the MCC to qua…
The effective atomic number (Zeff) and effective electron density (Neff) of eight heavy metal oxide (HMO) glasses have been determined using the Monte Carlo simulation code MCNP for the energy range of 10 keV–10 MeV. The interpolation method was employed to extract Zeff and Neff values from the simulation and that cal…
This work is focused on thermal analysis, metallurgical characterization, and laser treatment of an aluminium alloy. This paper contributes to a better understanding of non-equilibrium metallurgical character of aluminium alloys. The solidification of the aluminium dendritic network, the aluminium–silicon eutectic and…
The synthesis and electrochemical characterization of novel polymers bearing phenoxyl-radicals as redox-active side chains is described. The monomers are synthesized from the corresponding phenols and quinones, respectively. These compounds are subsequently poly-merized via ring-opening metathesis polymerization. The…
Abstract In this paper, a metalens based on the dielectric meta-reflectarray consisting of silicon nanorods in combination with a gold ground plane is proposed to realize an arbitrary focusing lens. We have demonstrated that the meta-reflectarray is served as a half-waveplate with near-unity reflectance and over 98% p…
Silver nanoparticles have been synthesized by subjecting a reaction medium to a Fusarium oxysporum biomass at 28 °C for 96 h. The biosynthesized Ag nanoparticles were characterized on the basis of their anticipated peak at 405 nm using UV-Vis-NIR spectroscopy. Structural confirmation was evident from the characteristi…
Biological routes of synthesising metal nanoparticles (NPs) using microbes have been gaining much attention due to their low toxicity and eco‐friendly nature. Pseudomonas aeruginosa JP2 isolated from metal contaminated soil was evaluated towards extracellular synthesis of silver NPs (AgNPs). Cell‐free extract (24 h) o…
The first examples of dimeric, di-Pt(II) -containing heteropolytungstates are reported. The two isomeric di-platinum(II)-containing 22-tungsto-2-phosphates [anti-Pt(II)2(α-PW11O39)2](10-) (1 a) and [syn-Pt(II)2(α-PW11O39)2](10-) (2 a) were synthesized in aqueous pH 3.5 medium using one-pot procedures. Polyanions 1 a a…
Ni83.25Zr16.75 peritectic alloy was containerlessly solidified in a drop tube. When the droplet diameter exceeds a critical value (Dcrit), Ni7Zr2 phase primarily solidifies, followed by the peritectic reaction of Ni7Zr2 + L → Ni5Zr. Once the droplet diameter is smaller than the critical value (Dcrit), peritectic phase…
The synthesis of dyad and triad aza-BODIPY-porphyrin systems in two steps starting from an aryl-substituted aza-BODIPY chromophore is described. The properties of the resulting aza-BODIPY-porphyrin conjugates have been extensively investigated by means of electrochemistry, spectroelectrochemistry, and absorption/emiss…
Multiferroic superlattices consisting of 15 double layers BaTiO3–BiFeO3 show a very high magnetoelectric voltage coefficient αME of up to 49 V cm−1 Oe−1 at 300 K, measured at 1 kHz with zero direct current (DC) bias magnetic field. However, the microscopic origins of such high αME values, and the temperature and DC ma…
