Polyvinyl acetate nanocomposites were successfully prepared based on silver nanoparticles. First, silver nanoparticles were directly prepared during the in situ emulsion polymerization of vinyl acetate monomer using AgNO3 as a source of Ag+ ions and poly(vinyl alcohol) was used for dual functions as emulsifier for emu…
A Cu nanowire (NW)/cuprous oxide (Cu 2 O)-based semiconductor-liquid junction solar cell with a greatly enhanced efficiency and reduced cost was assembled. The Cu NWs function as a transparent electrode as well as part of the Cu NWs/ Cu 2 O coaxial structures, which remarkably benefit the charge separation. The best s…
The present work reports the results of non-isothermal DSC measurements on some Se-based ternary glasses for evaluation of activation of glass transition. The activation energy of glass transition ( E g ) is determined using Augis–Bennett's relation, which is basically derived for amorphous to crystalline phase transi…
The high coercivity of 26.2 kOe for SmCo5 nanoflakes are obtained by multistep (three steps) surfactant-assisted ball milling. The magnetic properties, phase structure and morphology are studied by VSM, XRD and SEM, respectively. The results demonstrate that the three step ball-milling can keep more complete crystalli…
The external appearance of a crystal of active pharmaceutical ingredient (API), usually referred to as a crystal habit, has a substantial impact on the API's physicochemical and physiochemical properties and, subsequently, its pharmaceutical performance. In this work, we investigate the role of different parameters of…
A one-dimensional lithium(I) coordination polymer has been characterized by variable-temperature single-crystal X-ray diffraction and differential scanning calorimetry. This compound possesses an anisotropic packing arrangement that, along with a scissor-like or hingelike movement of the pyridyl ligand side arms, resu…
Collagens are an important family of structural proteins found in the extracellular matrix with triple helix as the characteristic structural motif. The collagen triplex is made of three left-handed polyproline II (PPII) helices with each PPII strand consisting of repetitive units of the tripeptide motif X-Y-Gly, wher…
A strategy to probe supramolecular nanocarriers and their cargo in the intracellular space was developed on the basis of fluorescence measurements and energy transfer. It relies on the covalent attachment of an energy donor, or acceptor, to the macromolecular backbone of amphiphilic polymers and the noncovalent encaps…
The article describes the mechanical properties and electromagnetic shielding of Co-doped ZnO–poly(vinyl alcohol) nanocomposite. Significant improvements in mechanical properties can be obtained by incorporating inorganic nano fillers. The E-modulus and tensile strength were found to be enhanced with the increase in t…
Eighteen new lanthanide transition metal heterobimetallic compounds, Ln 2 Co(TeO 3 ) 2 (SO 4 ) 2 (Ln = Y, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, or Lu) and Ln 2 Zn(TeO 3 ) 2 (SO 4 ) 2 (Ln = Sm, Gd, Dy, Ho, Er, or Yb), have been prepared. They crystallize in triclinic space group P 1̅ with two different structural top…
The pitting corrosion of welded joints of lean duplex stainless steel (LDSS) UNS S32304 was studied. LDSS S32304 thick plates were welded by different processes commonly employed in the manufacture of equipment and piping: shielded metal arc welding, gas metal arc welding, and flux cored arc welding. The electrochemic…
The scratch resistance behaviour of alumina-graphene nanoplatelet (GNP) (0.5, 2 and 5 vol.-%) composites was investigated using a Rockwell indenter with normal applied loads ranging from 1 to 200 N. The alumina-GNP composites behaved differently during scratch testing depending on the normal applied load. The coeffici…
We present the open-source computer program JETSPIN, specifically designed to simulate the electrospinning process of nanofibers. Its capabilities are shown with proper reference to the underlying model, as well as a description of the relevant input variables and associated test-case simulations. The various interact…
We study the photoisomerization of azobenzene chromophores embedded into a polymer matrix by using coarse-grained simulations. Two types of beads are considered: t- and c-beads, which are rich in trans and cis isomers, respectively. Simulations combine deterministic (molecular dynamics) and stochastic (random-type swi…
Using first-principles calculations, we investigate the effect of surface passivation on the impurity distribution and magnetic properties in Mn-doped GaAs nanowires . A comparative analysis for the zinc-blend and wurtzite structures is made. Our results show that when the Mn-doped position shifts from the center to t…
Superparamagnetic iron oxide nanoparticles (SPIONs) are frequently used for drug targeting, hyperthermia and other biomedical purposes. Recently, we have reported the synthesis of lauric acid-/albumin-coated iron oxide nanoparticles SEON(LA-BSA), which were synthesized using excess albumin. For optimization of magneti…
BACKGROUND: With life pace accelerated, poor diet habits developed, psychological burden enhanced and many other factors, the incidence of coronary heart disease, atherosclerosis and other cardiovascular cerebrovascular diseases has been increased year by year, which are serious threat to human health. OBJECTIVE: Prov…
Abstract In order to investigate the importance of biogenic silica associated biopolymers on the scavenging of radionuclides, the diatom Phaeodactylum tricornutum was incubated together with the radionuclides 234 Th, 233 Pa, 210 Pb, and 7 Be during their growth phase. Normalized affinity coefficients were determined f…
We propose a class of temperature-tunable semiconductor metamaterials for terahertz applications. These metamaterials are based on doped semiconductor superlattices with ultrathin barriers of about 1 nm thickness. Due to the tunnel transparency of the barriers, layers of the superlattice cannot be considered as isolat…
Abstract Thin film technology is applied in different fields of Li-ion battery research and development, such as the fabrication of thin film cells and model electrodes. Data obtained by surface and interface analysis of thin films provides important insights into fundamental processes such as charge compensation mech…
