The use of molecular diagnostic techniques for bioprospecting and microbial diversity study purposes has gained more attention thanks to their functionality, low cost and quick results. In this context, ten degenerate primers were designed for the amplification of polyhydroxyalkanoate synthase (phaC) gene, which is in…
Green synthesis of AgNPs has gained many research interests as a low cost and eco-friendly approach. This work reported on the use of bacterial genomic DNA as the alternative biopolymer for a green production of AgNPs under a neutral pH. Although both ssDNA and dsDNA could function as stabilizing agents during the syn…
The production of stable dispersions of carbon nanotubes (CNTs), synthesized by CVD, in different liquids, is one of the methods of preparation of CNTs for introduction into polymeric matrix. The aim of this work is to produce composites of polyethylene (PE) – CNT, and the study of their structural characteristics, me…
ABSTRACT Usually the metal nanoparticles are obtained by different chemical reactions that are not environmentally friendly. This paper describes the synthesis of two polyelectrolytes with sulfonate groups in ortho‐ position and in ortho‐ and para‐ positions, which were obtained by chemical modification of chitosan. T…
The effect of flexoelectricity on the formation and evolution of domain structures in ferroelectric materials is developed by integrating strain gradient theory into a finite element phase field model. Length scales associated with elastic strain gradients and the corresponding polarization gradient across a domain wa…
Grazing-incidence, wide-angle x-ray scattering measurements were conducted on indium oxide thin films grown on silica substrates via pulsed laser deposition. Growth temperatures (TG) in this study ranged from −50 °C to 600 °C, in order to investigate the thermal effects on the film structure and its spatial homogeneit…
Abstract In this study, a modified high temperature adhesive based on polyborosilazane preceramic was developed for joining graphite. The properties of adhesive as well as bonding performance of both directly cured joints and calcined joints were investigated. The results showed that the shear strength reached the hig…
Fuel-flexible solid oxide fuel cell (SOFC) technologies are presently under study in a Vietnam-Japan international joint research project. The purpose of this project is to develop and demonstrate an SOFC-incorporated energy circulation system for the sustainable development of the Mekong Delta region. Lab-scale metha…
The method of angular- and wavelength-dispersive ( e.g. two-dimensional) Rietveld refinement is a new and emerging tool for the analysis of neutron diffraction data measured at time-of-flight instruments with large area detectors. Following the approach for one-dimensional refinements (using either scattering angle or…
Electron transfer theory is used to explore the size-dependence of electron transfer (ET) between dithiol-bridged quantum dots (QDs) and make predictions that can be tested experimentally. Electronic couplings, electronic densities of states, and reaction-free energies are all found to be size-dependent and to influen…
Rheology is the science of deformation and flow of the matter due to the application of a force. Most rheological tests involve applying a force to a material and measuring its flow or change in shape. Rheological characterization is useful to study the flowability and viscoelastic properties of adhesive materials. Th…
Abstract Biomimetic, strain‐stiffening materials are reported, made through self‐assembly and covalent fixation of small building blocks to form fibrous hydrogels that are able to stiffen by an order of magnitude in response to applied stress. The gels consist of semi‐flexible rodlike micelles of bisurea bolaamphiphil…
The functionalized, asymmetric fluoro–fluoroalkyl scaffold F 48 H 7 COOHPcZn ( 3 ) was used to prepare F 48 H 7 COOPcZn-6-amino-hexanoate-CTVALPGGYVRVC ( 5 ), a Pep42 peptide bioconjugate envisioned for photodynamic therapy, which can specifically target the GRP78 chaperone protein overexpressed and exclusively locali…
Amorphous silicon carbonitride (a‐SiCN) films were produced by remote nitrogen plasma chemical vapour deposition (RP‐CVD) from bis(dimethylamino)methylsilane precursor. The effect of substrate temperature ( T S ) on the kinetics of RP‐CVD, chemical structure, surface morphology and some properties of the resulting fil…
Present study focuses on the terminal penetration of tungsten heavy alloy (WHA) long rod penetrator impacted against armour steel at an impact velocity of 1600 m/s. The residual penetrator and armour steel target recovered after the ballistic test have been characterized using optical microscope, scanning electron mic…
Perfect metamaterial absorber (MA)-based sensor applications are presented and investigated in the microwave frequency range. It is also experimentally analyzed and tested to verify the behavior of the MA. Suggested perfect MA-based sensor has a simple configuration which introduces flexibility to sense the dielectric…
Nanoparticles have shown promise in loading and delivering drugs for targeted therapy. Many progresses have been made in the design, synthesis, and modification of nanoparticles to fulfill such goals. However, realizing targeted intracellular delivery and controlled release of drugs remains challenging, partly because…
We report the synthesis, characterization, photophysical investigations, and cell‐uptake studies of luminescent silica nanoparticles incorporating covalently linked visible‐light‐excitable Eu 3+ complexes. Visible‐light excitation was accomplished by using highly conjugated carbazole‐based β‐diketonate ligands. Covale…
Wood-composite building products offer homogeneous structures that address the ever-growing needs of different industries for new materials with consistent, predictable, and unique qualities. However, they are susceptible to biological degradation; they are vulnerable to changes caused by water and water vapor; and fi…
Abstract GeSbTe-based materials exhibit multiple crystalline phases, from disordered rocksalt, to rocksalt with ordered vacancy layers, and to the stable trigonal phase. In this paper we investigate the role of the interfaces on the structural and electrical properties of Ge 2 Sb 2 Te 5 . We find that the site of nucl…
