In the present work, our investigation is to study the optical anisotropic properties of the binary mixture of cyano-benzilidene-p-n-octyl-oxy-aniline (CBOOA), cholesteryl nonanoate (CN), which exhibits a very interesting liquid crystalline Cho-TGB-SmC-SmA-SmB phases sequentially when the specimen cooled from its isot…
The isothermal and thermo‐mechanical fatigue behavior of the ferritic–austenitic duplex stainless steel X2CrNiMoN22‐5‐3 is investigated in the temperature range of 100–600 °C. Furthermore, isothermal and thermo‐mechanical fatigue tests on single‐phase ferritic and austenitic reference steels are carried out within the…
A novel coordination polymer [(VIVO)2(OH)2(C10H6(COO)2)]∞ based on vanadium(IV) and 2,6-naphthalenedicarboxylato ligand has been prepared by hydrothermal synthetic method. The compound was characterized by elemental analysis, thermogravimetric analysis, Fourier Transform infrared spectroscopy, room-temperature magneti…
"Lab on a particle" architecture is employed in designing a light nanosensor. Light-sensitive protecting groups are installed on DNA, which is encapsulated in silica particles, qualifying as a self-sufficient light sensor. The nanosensors allow measuring light intensity and duration in very small volumes, such as sing…
The radical polymerization of 1-vinylpyrrolidin-2-one (NVP) in poly(lactic-co-glycolic acid) (PLGA) 50:50 at 100 °C leads to amphiphilic PLGA-g-PVP copolymers. Their composition is determined by FT-IR spectroscopy. Thermogravimetric analyses agree with FT-IR determinations. Saponification of the PLGA-g-PVP polyester p…
The pressure effect on the ferroelectric (FE) properties of the multiferroic compounds GdMn2O5and TmMn2O5was studied up to 18.2 kbars. A new FE phase was observed at a higher temperature in GdMn2O5above a critical pressure, Pc≈10 kbars. Our results indicate that pressure decouples the Gd moment from Mn spin system and…
Ni1-xZnxFe2O4nanoparticles (x = 0.0 -1.0) were successfully prepared via sucrose-assisted autocombustion method. Thermal analysis measurements indicated that the ferrite nanoparticles could be synthesized in this self-propagating combustion process. The microstructure and magnetic properties were investigated by means…
This work explores a cost-effective route to enhance the tuning range of the optical response of metal nanostructures on substrates beyond the ranges that are achievable through the nanostructure dimensions, composition or dewetting processes. The new route (laser seeding) uses single nanosecond laser pulses to induce…
As a new type of topological poly(ethylene glycol) (PEG) analogue, a series of polygonal PEGs with digonal to hexagonal structures were developed. Polygonal PEGs with structures between the digonal and tetragonal types showed molecular-level dispersion in water at 20 °C, whereas the pentagonal and hexagonal PEGs aggre…
Ce-Nd-Fe-Mo nitrides with tetragonal ThMn12-type structures are promising compounds for hard magnetic applications. The key to enhance magnetic performance is the insertion of a light element, such as N into the 2b site of the crystal lattice. However, the nitrogenation also changes the thermodynamic stability of Ce-N…
Halogenated chalconyl derivatives of novel homologues of esters are synthesized and studied with a view to evaluate their liquid crystal (LC) properties and their dependence on molecular structure with reference to molecular rigidity and flexibility. Novel homologous series of chalconyl esters comprises 12 homologues.…
The multicomponent system of cholesteryl linolenate (CL), sodium oleate (Naol), and orthophosphoric acid (H3PO4) exhibits liquid crystalline mesophases, like cholesteric and smectic phases, such as SmA, SmC, SmB, and SmG sequentially when the specimen is cooled from its isotropic phase. These phases have been observed…
Fulminates containing the CNO(-) ion have been widely utilized as high-energy density materials (HEDMs) for more than 120 years. Yet no purely covalently bound CNO molecule, i.e., nitrile oxide, is known to behave as an HEDM. In this study, we performed a thorough investigation of the potential energy surface of nitri…
This paper discusses the investigation of the dipole formation at In2O3|TiO2 heterojunctions depending on preparation conditions, i.e., cleaning methods. In2O3 films were deposited using atomic layer deposition (ALD) onto solvent and in situ cleaned anatase and rutile film substrates. The interface dipole strength and…
In the present study, we report the dielectric behavior of a high temperature nematic liquid crystal (NLC) in both the planar as well as homeotropic alignments. To understand the mechanism of such high temperature NLC, we have performed dielectric spectroscopy in frequency range 100 Hz to 10 MHz. The different dielect…
In this work, a facile one-pot reaction for the formation of metal nanoparticles in a water solution through the use of n-(2-aminoethyl)-3-aminosilanetriol is presented. This compound can be used to effectively reduce and complex metal salts into metal core nanoparticles coated with the compound. By controlling the co…
We use a micromagnetic model based on the kinetic Monte-Carlo approach to investigate theoretically the magnetic properties of advanced recording media. The model is employed to examine the impact of the magnetostatic and exchange interaction between grains of realistic perpendicular recording media on the angular-dep…
A vanadium hydride for Kubas-type H2 storage is presented. Calorimetry shows that adsorption is thermodynamically neutral, meaning the material can be used in tanks without heat-management systems. More information can be found in the Full Paper by D. M. Antonelli et al. on page 822 in Issue 6, 2016 (DOI: 10.1002/cphc…
We present the results of high-pressure transport measurements on the anion-mixed molecular conductors (DIETSe)${}_{2}M{\mathrm{Br}}_{2}{\mathrm{Cl}}_{2}$ [DIETSe = diiodo(ethylenedithio)tetraselenafulvalene; $M=\mathrm{Fe}$, Ga]. They undergo a metal-insulator (M-I) transition below 9 K at ambient pressure, which is…
Joining experiments using different adhesives were carried out. In addition to the adhesive, the specimens were also treated with ultrasonic waves to improve the load carrying capacity of the joined parts. Lap joint shear tests have been conducted to quantify this improvement.
