The influence of the shape anisotropy of magnetic particles on the isotropic-nematic phase transi- tion was studied in ferronematics based on the nematic liquid crystal 4-(trans-4-n-hexylcyclohexyl)- isothiocyanato-benzene (6CHBT). The liquid crystal was doped with spherical or rod-like magnetic particles of different…
A rare earth mineral is defined as a mineral containing rare earth elements (REE: Sc, Y and lanthanoids) as essential constituents. So far, more than 280 species of RE minerals, as independent species, have been described after the official IMA-CNMNC approval. The chemical bonds between REE and anions possess largely…
To avoid the release of chrome from leather into post tanning effluents and the generation of chrome shavings, an inverse chrome tanning technology based on wet white was investigated. Conventional bated pelt was firstly tanned using an amphoteric organic tanning agent (Tingjiang white tanning agent, TWT) without pick…
Coping with plant diseases and pests are among the most critical problems of agriculture sector. “Fusarium oxysporum f. sp. lycopersici”, the fusariumwilt agent in tomato plant, is one of the important plant pathogens, which enjoys a global significance due to it severe damages. Taking into account the mutation of pat…
Carbonaceous nanocups attached on free-standing microtubes were prepared and used to trap MoS <sub>2</sub> nanosheets. Excellent cyclability and rate performance were achieved owing to efficient contact between the nanocups, nanosheets and electrolyte.
We present experimental studies of both local and macroscopic electrical effects in uniform single- (1LG) and bi-layer graphene (2LG) devices as well as in devices with non-uniform graphene coverage, under ambient conditions. DC transport measurements on sub-micron scale Hall bar devices were used to show a linear ris…
Nanostructured GaN-based light-emitting diode (LED), with its high performance on light extraction efficiency, has attracted significant attention for the potential application in solid state lighting. However, patterning structures at nanoscale feature size with large area and low cost is of great importance and hard…
A series of well-crystallized praseodymium oxide (Pr 6 O 11 ) nanoparticles are synthesized via a highly scalable process from praseodymium nitrate. Praseodymium hydroxide is synthesized through a modified polyol process and subsequent calcination in air at 600°C for 2 h to transform the precursor material into Pr 6 O…
New hybrid materials of polyaniline and hexaniobate nanoscrolls were prepared by the mixture of the dispersions. These materials show high doping of polyaniline and high thermal stability.
To study and locate partial discharge(PD) and analyze the transient state of power transformer, there is a need for a high frequency model of transformer winding and calculation of its parameters. Due to the high frequency nature of partial discharge phenomenon, there is a need for an accurate model for this frequency…
We investigated the influence of the composition of a 1,4-butanediol–water mixed solvent on the structural and particulate properties in the synthesis of well-dispersed YBO3:Ce3+,Tb3+ nanocrystals, without assembly, using a solvothermal method. YBO3:Ce3+,Tb3+ nanocrystals were synthesized from trimethyl borate and ace…
Density Functional Theory (DFT) was used to analyse and explain spin state energetics of first-row transition metals (Mn(II), Fe(II), Co(II); Cr(III), Mn(III), Fe(III), Co(III); Mn(IV)) in polypyrazolylborato complexes. We explored the effects of substitutions at the 3 and 5 positions of the pyrazolyl rings, as well a…
Glycosylated fluorescent organic nanoparticles (FONs) based on aggregation induced emission (AIE) dyes were fabricated for the first time through one-pot ring-opening reaction. These glycosylated AIE dye based FONs showed uniform morphology, high water dispersibility, strong red fluorescence and excellent biocompatibi…
Nanocomposites of colloidal quantum dots (QDs) integrated into conjugated polymers (CPs) are key to hybrid optoelectronics, where engineering the excitonic interactions at the nanoscale is crucial. For such excitonic operation, it was believed that exciton diffusion is essential to realize nonradiative energy transfer…
The main focus of this paper is aimed at a description of the relationship between the air permeability of woven fabric and its structure. The porosity of the fabric is divided into two basic types: horizontal and vertical porosity. The horizontal porosity is considered as a complement to the woven fabric cover factor…
A pH-responsive, multiple chemotherapeutic agent derived nanocarrier has been synthesized by conjugating doxorubicin, indomethacin, and folate to the backbone of norbornene polymer. Drug molecules are connected to the norbornene backbone by an ester linker to demonstrate the pH-responsive capabilities. The complete ch…
In this work we perform mechanical stretching tests while monitoring optical and ionic transport properties of ion-intercalated semi-crystalline polyethylene-oxide (PEO) electrolytes in-situ. Utilizing ionic liquid (EMIBF 4 ) – PEO electrolytes, we demonstrate a correlation between the degree of crystallinity, which d…
We have studied the magnetocaloric effect in high-energy ball-milled (Fe70Ni30)95Mn5alloy nanoparticles. The partial substitution of Fe and Ni by Mn decreases the Curie temperature (TC) of the alloy to 338 K from 443 K. The change in entropy (Δ SM) occurs over a broad range of temperatures, which results in high relat…
Solid–liquid mechanochemical ball-milling to produce tuneable Si nanoparticle sizes to improve hydrogen storage system reaction kinetics.
The natural antitumor drug camptothecin was found to self-assemble into helical nanoribbons in aqueous solution. The formation and disappearance of the helical nanoribbons can be tuned reversibly through changing the pH value of the solution.
