Development of safe and effective hydrogen storage systems is critical for further implementation of hydrogen in fuel cell technologies. Amongst the various approaches to improve the performance of such systems, porous materials-based adsorptive hydrogen storage is envisaged as a long-term solution because of the exce…
Neutron crystallography allows direct localization of hydrogen positions in biological macromolecules. Within enzymes, hydrogen atoms play a pivotal role in catalysis. Recent advances in instrumentation and sample preparation have helped to overcome the difficulties of performing neutron diffraction experiments on pro…
When shape memory alloys are subjected to cyclic loadings, the stabilized dissipated energy is an effective parameter in studying their performance, for instance, the fatigue life. However, thermomechanical coupling in the behavior of shape memory alloys under cyclic loadings causes the amount of stabilized dissipated…
Three chiral dinuclear lanthanide compounds, Ln2(µ2-L)4(L)2(phen)2 (Ln = Dy (1), Gd (2), and Er (3); phen = 1,10-phenanthroline), have been synthesized using the (S)-(+)-2-(6-methoxy-2-naphthyl)propionic acid (HL) ligand. The two lanthanide centres in compound Ln2(µ2-L)4(L)2(phen)2 are bridged by four carboxylate grou…
Despite obvious differences in morphology, substratum chemistry and the electrolyte in which they form, accumulations of iron corrosion products have the following characteristics in common: stratification of iron oxides/hydroxides with a preponderance of α-FeOOH (goethite) and accumulation of metals. Bacteria, partic…
Diatom biofilms are abundant in the marine environment. It is assumed (but untested) that extracellular polymeric substances (EPS), produced by diatoms, enable cells to cope with fluctuating salinity. To determine the protective role of EPS, Cylindrotheca closterium was grown in xanthan gum at salinities of 35, 50, 70…
Nanoparticles (NPs) provide several advantages over the small molecule drugs including prolonged circulation time and enhanced delivery to targeted sites. Once a NP enters the body, it interacts with host's immune system and is engulfed by cells of the mononuclear phagocyte system (MPS). The interaction between NPs an…
Systematic studies of magnetic properties of LaSr2Mn2O7 as a function of crystalline grain size provide information on how the crystalline grain size affects the magnetic and charge ordering in this compound. The half-doped bi-layered manganite LaSr2Mn2O7 (x=0.5) in its bulk form has CE-type antiferromagnetic (CE-AFM)…
Silver nanoparticle (AgNP) was synthesized using the cell free extract of Scenedesmus abundans with AgNO3. The synthesized silver nanoparticles were characterized by UV-visible spectroscopy, dynamic light scattering (DLS), scanning electron microscopy (SEM), and Photoluminescence. Bioreduction of Ag+ ions showed a gra…
Smart fabrics allow for convenient wearable sensing solutions to monitor body movements during our daily life. However, garment-integrated sensing presents challenges for accurate sensing, due many variables including those presented by variability in garment and sensor dimensions due to cut-and-sew manufacturing proc…
PURPOSE: To investigate the feasibility of an accurate measurement of water, lipid, and protein composition of breast tissue using a photon-counting spectral computed tomography (CT) with spectral distortion corrections. METHODS: Thirty-eight postmortem breasts were imaged with a cadmium-zinc-telluride-based photon-co…
An effective way to monitor body movements and positions (including physiological signals like breathing) without causing discomfort is through integration of sensors and electronics into base layers of clothing. However, for many applications (including sports and fitness), such sensors must be washable. Here, we pre…
Abstract The effects of ytterbium (Yb) on microstructure and solidification behavior of Al–9.00 %Si–0.25 %Mg alloys were investigated. By optical microscope (OM) and scanning electron microscopy (SEM), it is found that the morphology of eutectic silicon changes from coarse plates to fine fibers by the addition of 0.7…
For workers in extreme environments, such as firefighters, thermal protective clothing is essential to protect them from exposures to high heat and life threatening risks. This study will investigate the design of a new smart protective clothing system, which incorporates sensors in the undergarment to measure physiol…
Dry granulation, as a new process of molten blast furnace slag (BFS) treatment, is an attractive alternative to water quenching. The performance of BFS obtained from dry granulation must be assessed. The glass content, which is a significant factor to evaluate the performance of BFS as a replacement material for Portl…
Organ printing, among different tissue engineering innovations, is a freeform fabrication approach for making three-dimensional (3D) tissue and organ constructs using cellular spheroids or bioinks as building blocks. The capability to fabricate vascular-like tubular constructs is an important indicator of the overall…
Bacillus coagulans 2-6 is an excellent producer of optically pure l-lactic acid. However, little is known about the mechanism of synthesis of the highly optically pure l-lactic acid produced by this strain. Three enzymes responsible for lactic acid production-NAD-dependent l-lactate dehydrogenase (l-nLDH; encoded by l…
The umbilical cord (UC) has become one of the major sources of mesenchymal stem cells (MSCs). The common explant method of isolating UC-derived MSCs (UC-MSCs) involves mincing the UCs into small fragments, which are then attached to a culture dish bottom from which the MSCs migrate. However, the fragments frequently f…
Nanoparticles synthesis by bacteria and yeasts has been widely reported, however, synthesis using halophilic archaea is still in a nascent stage. This study aimed at the intracellular synthesis of selenium nanoparticles (SeNPs) by the haloarchaeon Halococcus salifodinae BK18 when grown in the presence of sodium seleni…
Abstract CoFe2O4-graphene nanosheets (CoFe2O4-GNSs) were synthesized through an ultrasonic method, and their electrochemical performances as Li-ion battery electrode were improved by annealing processes. The nanocomposites obtained at 350 °C maintained a high specific capacity of 1,257 mAh g−1 even after 200 cycles at…
