Post-operatory infections in orthopedic surgeries pose a significant risk. The common approach of using antibiotics, both parenterally or embedded in bone cement (when this is employed during surgery) faces the challenge of the rising population of pathogens exhibiting resistance properties against one or more of thes…
Efficiency of 9.2% on Cu2ZnSnS4submodule was achieved by applying hybrid buffer layer with combination of In-based buffer and Cd-based buffer layers. The hybrid buffer especially enhanced open circuit voltage. Finally world highest voltage of 758mV was achieved by this technique. The XPS depth profile showed there was…
In order to significantly increase the power density of light water reactors (LWRs), the authors propose the helical-cruciform (HC) fuel rod assembly as an alternative to traditional fuel geometry. The HC fuel rod assembly is a self-supporting nuclear fuel configuration consisting of four-petalled, axially twisted fue…
A nanofluid is a dilute liquid suspension of particles with at least one critical dimension smaller than ~100 nm. Research works so far suggest that nanofluids offer excellent heat transfer enhancement over conventional base fluids. The enhancement depends on several factors such as particle shape, particle size distr…
Pastes of granulated blast furnace slag (GBFS) and metakaolin (MK) at GBFS/MK mass ratios of 100/0, 50/50, and 0/100 were activated with sodium silicate with modulus (Ms) SiO2/Na2O of 1, 1.5, and 2, and with 5, 10, and 15% Na2O, relative to the mass binder. Samples were cured at 20 °C for up to 720 days, compressive s…
Nanoscratch testing, as an important technique for the assessment of the mechanical failure behaviour and adhesion strength of ceramic coatings and a simulation tool of single asperity contact in tribological experiments, is increasingly becoming an established nanomechanical characterisation method. This paper review…
Abstract 5% (molar ratio) Fe doped TiO 2 nanoparticles were prepared by a sol gel method and the post annealing of the samples was carried out at 400 °C, 600 °C and 800 °C in air. Structural characterization of the samples was carried out using High Resolution Transmission Electron Microscopy (HRTEM). HRTEM images of…
Short- and medium-chain chlorinated paraffins are potential PBT chemicals (persistent, bioaccumulative, toxic) and short-chain chlorinated paraffins are under review for inclusion in the UNEP Stockholm Convention on Persistent Organic Pollutants. Despite their high production volume of more than one million metric ton…
A novel class of ZnCo2O4-urchins-on-carbon-fibers matrix has been designed, characterized, and used to fabricate high-performance energy storage devices. We obtained a reversible lithium storage capacity of 1180 mA·h/g even after 100 cycles, demonstrating the highreversible capacity and excellent cycle life of the as-…
A thermoelectric energy harvester powered wireless sensor networks (WSNs) module designed for building energy management (BEM) applications is built and tested in this work. An analytic thermoelectric generator (TEG) electrical model is built and verified based on parameters given in manufacturer data sheets of Bismut…
Recent efforts in the computational evaluation of the thermodynamic properties of water molecules have resulted in the development of promising new in silico methods to evaluate the role of water in ligand binding. These methods include WaterMap, SZMAP, GRID/CRY probe, and Grand Canonical Monte Carlo simulations. They…
Phytic acid is a natural compound widely used as depigmenting agent in galenic cosmetic emulsions. However, we have observed experimentally that phytic acid, when heated to 150 ºC for around one hour, shows evidence of thermal decomposition. Few studies investigating this substance alone with regard to its stability a…
Whereas the plastid caseinolytic peptidase (Clp) P protease system is essential for plant development, substrates and substrate selection mechanisms are unknown. Bacterial ClpS is involved in N-degron substrate selection and delivery to the ClpAP protease. Through phylogenetic analysis, we show that all angiosperms co…
The natural dye, curcumin, was extracted from Curcuma longa L. using a simple extraction technique. The dye was then used as a sensitizer in a dye-sensitized solar cell (DSSC) without further purification, and its characteristics were studied. The dye was treated with acetic, nitric and hydrochloric acid for stabiliza…
Content Centric Networking (CCN) is a recently proposed information-centric Internet architecture in which the main network abstraction is represented by location-agnostic content identifiers instead of node identifiers. In CCN each content object is divided into packet-size chunks. When a content object is transferre…
Aptamers are single-stranded oligonucleotides synthesized through an in vitro selection and amplification process that involves systematic evolution of ligands by exponential enrichment. Based on their high binding affinity and specificity towards other molecules, aptamers generated during the final rounds of selectio…
Previous research work has found that catenary action can significantly increase structural resistance in addition to flexural capacity under column removal scenarios. However, whether reinforcements in beams can effectively function as ties to develop catenary action against progressive collapse is a big concern in c…
This short review article summarizes recent progress in research on various stimuli-responsive circularly polarized luminescence (CPL) properties derived from π-conjugated molecules and related materials. As representative examples, assembled structures of chiral π-conjugated polymers and molecules showed tunable CPL…
The performance of 23 density functionals, including one LDA, four GGAs, three meta-GGAs, three hybrid GGAs, eight hybrid meta-GGAs, and ten double-hybrid functionals, was investigated for the computation of activation energies of various covalent main-group single bonds by four catalysts: Pd, PdCl(-), PdCl2, and Ni (…
Various morphologies of CuO nanostructures (oval, cluster, leaves, small rod, porus nanosheets) have been synthesized by novel simple method using microwave radiation. The produced CuO nanostructures were characterized by X-ray diffraction analysis technique (XRD), transmission electron microscopy (TEM), surface area…
