Potential of luminescent bacteria in production of metal nanoparticles (NPs) has not been well evaluated up until now. These bacteria contain lux operon which is included of reductase enzymes, by increasing bacterial cell density, the expression of aldehyde synthetic enzymes elevate and enhance the yields of NPs synth…
New poly(L-lysine)-b-poly(ethylene glycol) copolypeptides have been prepared, where the side-chain amine groups of lysine residues are modified to contain ortho-amine substituted phenylboronic acid, i.e., Wulff-type phenylboronic acid (WBA), groups to improve their pH responsive, carbohydrate binding properties. These…
Room temperature ferromagnetic semiconductors have a great deal of advantage because of their easy integration into semiconductor devices. ZnS nanocrystals (NCs), bulk, and surfaces exhibit d0 ferromagnetism at room temperature. The experiments reveal that NC ferromagnetism takes place at low and room temperatures onl…
Magnetic and thermodynamic properties of perovskite Gd 0.2 Sr 0.8 CoO 3−δ, with ordered and disordered states of Gd and Sr in the A -sites of the crystal lattice have been studied revealing remarkable differences in the physical properties of the ordered and disordered states. The ordered samples have larger oxygen no…
This paper proposes the primary differential pulse method (PDPM) for the live partial-discharge (PD) detection of oil-immersed inverted current transformers. The PDPM is based on the differential current measurements that are taken at the high-voltage side of the current transformer under test. The proposed technique…
Noninvasive concentric ring electrodes are a promising alternative to conventional disc electrodes. Currently, the superiority of tripolar concentric ring electrodes over disc electrodes, in particular, in accuracy of Laplacian estimation, has been demonstrated in a range of applications. In our recent work, we have s…
Using fast scanning calorimetry, we determined the crystallinity of thin films of poly(3-hexylthiophene) crystallized from the melt from measurements of the specific melting enthalpy. A broad range of film thicknesses from 10 µm down to 26 nm was covered. The sample mass was determined from measurements of the specifi…
When materials are under stretching, occurrence of lateral contraction of materials is commonly observed. This is because Poisson's ratio, the quantity describes the relationship between a lateral strain and applied strain, is positive for nearly all materials. There are some reported structures and materials having n…
Potassium–sodium niobate ( KNN )‐based piezoelectric ceramic coatings with single perovskite phase and dense morphology were obtained by thermal spray processing. The structure, morphology, and properties of the coatings deposited at different conditions were investigated, and excellent piezoelectric performance prope…
The polyacrylonitrile/polymethyl-methacrylate (PMMA/PAN) porous fibers, core-shell hollow fibers, and porous thin films are prepared by coaxial electrospinning, single electrospinning, and spin-coating technologies, respectively. The different morphologies arising from different processes display great influences on t…
Multi-walled carbon nanotubes (CNTs) were directly used as a sustainable and green catalyst to convert ethanol into acetaldehyde in the presence of molecular oxygen. The C=O groups generated on the nanocarbon surface were demonstrated as active sites for the selective oxidation of ethanol to acetaldehyde. The transfor…
A series of dinuclear lanthanide complexes, [Dy 2 (LH) 2 (µ 2 ‐Piv‐κ 2 O , O ′) 2 (NO 3 ‐κ 2 O , O ′) 2 ] ( 1 ), [Tb 2 (LH) 2 (µ 2 ‐Piv‐κ 2 O , O ′) 2 (NO 3 ‐κ 2 O , O ′) 2 ] ( 2 ), [Gd 2 (LH) 2 (µ 2 ‐Piv‐κ 2 O , O ′) 2 (NO 3 ‐κ 2 O , O ′) 2 ] ( 3 ), and [Ho 2 (LH) 2 (µ 2 ‐Piv‐κ 2 O , O ′) 2 (NO 3 ‐κ 2 O , O ′) 2 ] (…
Electrospun poly-l-lactic acid (PLLA) nanofiber mats carrying surface amine groups, previously introduced by nitrogen atmospheric pressure nonequilibrium plasma, are embedded into aqueous solutions of oligomeric acrylamide-end capped AGMA1, a biocompatible polyamidoamine with arg-gly-asp (RGD)-reminiscent repeating un…
The development of alternative testing strategies (ATS) for hazard assessment of new and emerging materials is high on the agenda of scientists, funders, and regulators. The relatively large number of nanomaterials on the market and under development means that an increasing emphasis will be placed on the use of relia…
The aim of our research activity was to obtain a biocompatible nanostructured composite based on naturally derived biopolymers (chitin and sodium alginate) loaded with commercial antibiotics (either Cefuroxime or Cefepime) with dual functions, namely promoting wound healing and assuring the local delivery of the loade…
Proteins often possess highly specific biological activities that make them potential therapeutics, but their physical and chemical instabilities during formulation, storage, and delivery have limited their medical use. Therefore, engineering of nanosized vehicles to stabilize protein therapeutics and to allow for tar…
Various techniques and approaches have been designed to synthesize precipitated calcium carbonate. We used a continuous sprayed-mist technique that induced spontaneous precipitation reaction of the droplets with the higher surface area when in contact with the gas. The effects of optimum reactant concentration, gas fl…
This report is the first describing experimental evaluation of Fano factor for diamond detectors. High‐quality self‐standing chemical vapor deposited diamond samples were produced using lift‐off method. Alpha‐particle induced charge measurements were taken for three samples. A 13.1 ±0.07 eV of the average electron–hol…
Understanding the details of the electronic structure in face-to-face arranged tetrathiafulvalenes (TTFs) is very important for the design of supramolecular functional materials and superior conductive organic materials. This article is a comprehensive study of the interactions among columnar stacked TTFs using trimer…
Dual-component microcapsules were synthesized by solvent evaporation technique using epoxy resin and hardener as core materials and polymethyl methacrylate (PMMA) as shell wall materials. Morphology, core content, and size distribution of microcapsules were monitored by controlling the various processing parameters su…
