Optical properties of hexagonal multiferroic oxides $R\mathrm{Mn}{\mathrm{O}}_{3}$, where $R=\mathrm{Ho}$, Er, Tm, Yb, and Lu, have been studied in the far-infrared spectral range between 100 and 2000 cm${}^{\ensuremath{-}1}$ and temperatures between 1.5 and 300 K by means of several experimental techniques: Mueller m…
Random copolyesters of poly(l-lactic acid) (PLLA) and [poly(1,4-cyclohexylenedimethylene-1,4- cyclohexanedicarboxylate)] (PCCD) incorporating varying mol ratios of perylene bisimide (PBI) were developed via a high-temperature solution-blending approach. PCCD incorporating PBI was developed by melt polycondenzation fol…
Ball milling experiments were conducted with and without ultrasound wave assistance in deionized water using NiCO3·2Ni(OH)2·4H2O as raw materials. In the reaction process of NiFe2O4 prepared by ultrasound-assisted aqueous solution ball milling, some influencing factors including raw materials, ultrasonic frequency, ba…
The understanding that common broad-spectrum antimicrobials disrupt natural microbial flora important in acquiring nutrients and preventing infection has resulted in a paradigm shift favoring more selective antimicrobials. This work explores silver nanoparticles conjugated with ceragenin, or cationic antimicrobials (C…
Ni-assisted thermal chemical vapor deposition (TCVD) is one of the most common techniques for the growth of carbon nanofibres/nanotubes (CNFs/CNTs). However, some fundamental issues related to the catalytic growth of CNFs/CNTs, such as the low-limit growth temperature, the limiting steps and the state of Ni, are still…
We have investigated the molecular orientation and magnetic properties of vanadyl phthalocyanine (VOPc) deposited on ferromagnetic Fe, Co, and Ni films, which were epitaxially grown on Cu(001) using X-ray absorption spectroscopy and X-ray magnetic circular dichroism. The results reveal that the VOPc framework lies fla…
Ge 2 Sb 2 Te 5 (GST) phase change nanowires have been fabricated using a top-down spacer etch process. This approach enables controls over the dimension and location of the nanowires without affecting the electrical properties. Phase change devices based on these nanowires have been used to systematically investigate…
We investigated the interface between hexagonal ZnO films and cubic MgO (001) substrates, fabricated via molecular beam epitaxy. X-ray diffraction and (scanning) transmission electron microscopy revealed that growth follows the single [0001] direction when the temperature of the substrate is above 200 °C, while when t…
Low-loss lenses are required for submillimeter astronomical applications, such as instrumentation for CCAT, a 25 m diameter telescope to be built at an elevation of 18,400 ft in Chile. Silicon is a leading candidate for dielectric lenses due to its low transmission loss and high index of refraction; however, the latte…
Simple methodology for evaluating availability of self-healing agent has been established from the investigation on the relationship between oxidation behavior of self-healing agent and self-healing phenomena. The consistency of the established methodology was discussed by comparison in the lower bound of the availabl…
We present a detailed study of the evolution of the electrical, galvanomagnetic, and thermodynamic properties of polycrystalline Ag x Mo 9 Se 11 compounds for 3.4 ≤ x ≤ 3.8 at low temperatures (2–350 K). In agreement with density functional theory calculations, the collected data show an overall gradual variation in t…
ABSTRACT The PP Composites containing Xanthoceras sorbifolia Bunge husks fibers with different surface treatments were prepared. The mechanical properties such as tensile properties and impact properties of the composites were investigated. It is revealed that the composites with fibers treated by alkali and the follo…
We demonstrated an efficient and robust approach for the preparation of polymer/quantum dot (QD) nanocomposite thin films in nonpolar media. By employing photopolymerization based on the thiol-ene reaction, thiol-containing polymer with affinity groups for CdSe@CdS QDs was produced for the buildup of the polymer/CdSe@…
A novel aggregation-induced emission active dye consisting of a simple and highly solvatochromic D-π-A type 1,1′-binaphthyl chromophore was synthesised. The new dye exhibited dual-mode fluorescence in response to different types of restriction of intramolecular rotation; aggregation induces green emission, and blue em…
Diatoms are an ecologically successful group within the phytoplankton, and their special feature is a biofabricated silica cell encasement called a frustule. These frustules attract interest in material technology, and one potential application is to use them in solar cell technology. The silica frustule with its nano…
The atomic and magnetic structure of the 1/1 Tb(14)Au(70)Si(16) quasicrystal approximant has been solved by combining x-ray and neutron diffraction data. The atomic structure is classified as a Tsai-type 1/1 approximant with certain structural deviations from the prototype structures; there are additional atomic posit…
Attaching a self-complementary zwitterionic supramolecular binding site to the amino groups of polyethyleneimine leads to a pH switchable hydrogel as dimerization of the zwitterions introduces additional crosslinks between the polymer chains. This gel responds to both the addition of either acid or base, as only the z…
Thermoelectric (TE) modules utilize available temperature differences to generate electricity by the Seebeck effect. The current study investigates the merits of employing thermoelectrics to harvest additional electric energy instead of just cooling concentrating photovoltaic (CPV) modules by heat sinks (heat extracto…
Abstract An iodine molecule was successfully inserted into the inner cavity of a tiara‐like octanuclear palladium thiolate complex, [Pd(μ‐SCH2CO2Me)2]8. The included iodine molecule coordinated weakly to six palladium atoms in both linear and bent modes, as confirmed by X‐ray crystallography and DFT calculations. The…
with tagging errors on pages 3 and 6. On page 3, the eleventh line of the second paragraph in the left-hand column should read as "production (M ll < 1 GeV=c 2 ) [4]. Their vacuum"; on page 6, the eleventh line of the right-hand column should read as "pairs, and the p T suppression factor on the single electron".
