We describe a high-throughput characterization of near-infrared thermochromism in V1-xNbxO2 combinatorial thin film libraries. The oxide thin film library was prepared with a VO2 crystal structure and a continuous gradient in composition with Nb concentrations in the range of less than 1% to 45%. The thermochromic pha…
Single crystal silicon nanoparticles (Si-NPs) of 20 nm were produced via laser pyrolysis with a virtually complete conversion from SiH4 to Si-NPs. SF6 was used as the photosensitizer to transfer laser beam energy to silicon precursors, dramatically enhancing crystallinity of Si-NPs and their production efficiency. By…
Abstract New experimental measurements of the phase diagram and the mixing enthalpy of liquid phase along with the previous experimental data were used in a reassessment of the Ni–Ga system. A set of self‐consistent thermodynamic parameters of the Ni–Ga system is obtained using the calculation of phase diagram (CALPHA…
ABSTRACT Blends were obtained from poly(vinyl alcohol‐ co ‐ethylene) and water‐soluble biopolymers isolated from the alkaline hydrolysate of two materials sampled from an urban waste treatment plant: that is, an anaerobic fermentation digestate and a compost. The digestate biopolymers contained more lipophilic and ali…
We measure biexciton Auger recombination (AR) in colloidal graphene quantum dots (GQDs) by transient absorption spectroscopy. AR is reflected in GQDs with 132 and 168 sp2-hybridized C atoms as a decay with a ∼0.3 ps time constant and an amplitude depending superlinearly on pump fluence. Despite the orders-of-magnitude…
In this study, discarded denim fabric was adopted to enhance the mechanical and thermal properties of polypropylene (PP). The composites with different fiber weight fractions were designed and fabricated by using a hand layup and hot pressing method. The tensile, impact, and flame-retardant properties of the composite…
A facile synthetic strategy was developed for a hollow Ru octahedral nanocage via an in situ generated metastable facet-controlled Cu nanooctahedron. Co-decomposition of Cu and Ru precursors forms a metastable core-shell Cu@Ru nanoparticle, and a subsequent in situ dissolution of the core Cu phase results in a hollow…
ABAB-type Zn(II) phthalocyanines, crosswise-functionalized with two and four iodine atoms, respectively, have been efficiently prepared using statistical condensation procedures. Key to the selective preparation of the opposite ABAB isomers versus the adjacent AABB ones is the use of bulky 3,6-(3',5'-bis(trifluorometh…
ABSTRACT A green composite with good mechanical properties and acceptable biodegradability was developed using wood flour and soybean protein that was modified by thermal‐caustic degradation and chemical crosslinking with glyoxal and polyisocyanate (PMDI). Fourier transform infrared (FTIR) spectroscopy and scanning el…
We have investigated the direct laser interference patterning (DLIP) of tetrahedral amorphous carbon (ta-C) thin films in the nanometer region. In this paper we achieved texturing of ta-C from a surface swelling either by a phase change from sp 3 to sp 2 or thin film delamination. In contrast to surface ablation, the…
This review is focused on consideration of the influence of ligands and synthetic conditions on the structure and optical properties of a variety of metal complexes based on derivatives of quinoline, quinoxaline, and quinazoline. It has been established that changing of substituents in a given ligand provides an oppor…
Cadmium oxide nanoparticles synthesised by a simple sol–gel synthesis method showed luminescence properties in the visible region of the electromagnetic spectrum. Both green and blue emissions were observed in photoluminescence spectra. We have investigated luminescence properties by changing the synthesis conditions.…
Cubical ZrO 2 phosphor doped with the europium synthesized by conventional solid state synthesis method. The prepared phosphor was characterized by X-ray diffraction (XRD) technique, field emission gun scanning electron microscopy (FEGSEM) and transmission electron microscopy (TEM). In this paper, we focused on the th…
This photophysical study characterizes the generality of intermolecular electronic interactions present within nanomaterials derived from self-assembling oligopeptides with embedded π-conjugated oligophenylenevinylene (OPV) subunits stilbene and distyrylbenzene that in principle present two distinct β-sheet motifs. Tw…
Ionic liquids have become a popular solvent for cellulose pretreatment in biorefineries due to their efficiency in dissolution and their reusability. Understanding the interactions between cations, anions, and cellulose is key to the development of better solvents and the improvement of pretreatment conditions. While…
The main photophysical properties of a series of recently synthetized 1,2- and 1,3-squaraines, including absorption electronic spectra, singlet-triplet energy gaps, and spin-orbit matrix elements, have been investigated by means of density functional theory (DFT) and time-dependent DFT approaches. A benchmark of three…
Bicrystalline materials have wide applications from silicon chips to photocatalysis, but the controlled synthesis of nanocrytals with ordered phase junction has been challenging, in particular via chemical synesthetic routes. Here, we propose a general strategy to design biphase crystals formed via partial solid-to-so…

ZnO nanomaterials with large surface area are desired particularly for the gas sensor, biosensor and photocatalyst applications. In this study, ZnO hexagonal nanodisks with thickness to diagonal aspect ratio (∼1/80) were successfully synthesised via sol–gel approach. By using aluminium sulphate as a complexing agent a…
