With the initial motivation of optimizing hydrogen storage in beryllium nanocrystals, we have thoroughly and systematically studied the structural, cohesive, and electronic properties of Ben and BenHxn (n = 2-160, x = 0.1-2.4) nanoparticles as a function of both size (n) and hydrogen content (x), using density functio…
Magnetic nanoparticles (MNPs) have great potential in biomedical applications because of their magnetic response offers the possibility to direct them to specific areas and target biological entities. Magnetic separation of biomolecules is one of the most important applications of MNPs because their versatility in det…
We present a simple template carbonization method to produce nanoporous carbons in which potassium biphthalate and magnesium powder serve as the carbon source and hard template, respectively. It reveals that increasing the carbonization temperature can lead to an increase in crystallinity but porosity and the resultan…
Biodegradable copolymers of <sc>l</sc> -lactic acid and ε-caprolactone were prepared in SFBAILs: the effect of ILs and the mechanism.
The luminescence of semiconductor nanostructures is strongly dependent on their size, dimensions, morphology, composition, or defects, and their band emissions can be properly and selectively tailored through the rational manipulation of these parameters during material growth. Using spatially-resolved cathodoluminesc…
As the increasing demands of compact and space-saving electronics, capacitors with high energy-storage density are eagerly desired. One of the greatest challenges in the development of new high energy density materials is to increase dielectric permittivity. In this present work, we present some first results relative…
A 3-D cellular automaton finite difference (3-D CAFD) model to predict the solidification grain structure and the microsegregation was developed. In the present model, a new approach to calculate the solute concentration distribution was developed. Moreover, the CA cell including the grain boundary was newly defined.…
Plasma Electrolytic Oxidation (PEO) is a surface treatment for the production of ceramic oxide coatings with great properties, such as high wear and corrosion resistance, on metal substrates, particularly aluminum and magnesium alloys. Formation of PEO coatings involves complex processes and mechanisms that are diffic…
Graphene platelets (GnPs) were surface modi- fied with a long-chain surfactant B200, and then com- pounded with polymethyl methacrylate (PMMA). B200 provided an anchor into GnPs and a bridge into the matrix, thus creating molecular entanglement between matrix and GnPs. The interface modification promoted the dispersio…
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…
