To obtain much higher accurate jetting dispensing, an investigation on a jetting valve with ball needle and conical nozzle is done in this paper. The theoretical model on the relationship among needle, nozzle, and adhesive during the impact process is established first. The experiments are done on a jetting valve prot…
The UV‐excitable fluorescent poly(lactic acid) (PLA) fibers were spun by the traditional melt spinning process, and the effects of the fluorescent powder content (w(FP)) and draw ratio (DR) on the structure and properties of the fluorescent PLA fibers were investigated, respectively. The results showed that the emissi…
A non-volatile four-state magnetic memory is achieved in a Co/(011)Pb(Mg1/3Nb2/3)O3-PbTiO3 heterostructure. The in-plane magnetization of ferromagnetic Co film in the heterostructure can be controlled both electrically and magnetically. Electric field mediated magnetism is caused by piezostrain effect, which displays…
Bridge damage due to over-height vehicle collisions is a major issue throughout the transportation network with damages ranging from minor distortion or spalling in fascia girders to almost complete bridge destruction. Repairing such damages resulted from over-height vehicle collisions is expensive, and it includes co…
Abstract The synthesis and characterization of a family of compounds (pipzH2)[CrIII2LnIII4(µ4‐O)2(µ3‐OH)4(H2O)10(µ3‐SO4)4(SO4)2]·2H2O [hereafter abbreviated as Cr2Ln4; Ln = Tb (1), Ho (2), Er (3), Yb (4), and Y (5); pipz = piperazine] are reported. The compounds were obtained from hydrothermal reactions of Ln(NO3)3·6H…
In this paper, the crystallization behavior of nitrogen‐doped SbSe films was investigated as a function of nitrogen content. We found that the SET resistance and crystallization temperature of nitrogen‐doped SbSe films were higher than those of un‐doped SbSe films. Moreover, the crystallinity and average grain area de…
This work aims to develop a rapid and efficient strategy for preparing supported metal catalysts for catalytic applications. The sonication-assisted reduction–precipitation method was employed to prepare the heterogeneous mono- and bi-metallic catalysts for photocatalytic degradation of methyl orange (MO) and preferen…
This study described the utility of green analytical chemistry in the synthesis of gelatin-capped silver, gold and bimetallic gold-silver nanoparticles (NPs). The preparation of nanoparticles was based on the reaction of silver nitrate or chlorauric acid with a 1.0 wt% aqueous gelatin solution at 50°C. The gelatin-cap…
In the present study, we investigate the structural, morphological and magnetic properties of sol–gel spin-coated PZT thin films on alumina substrate. The morphotropic phase boundary (MPB) of PZT [Pb (Zr 1−x Ti x )0 3 ] between the tetragonal and rhombohedral phases occurs at the Zr/Ti ratio of 52/48. At the MPB the p…
Structural evolution and ferroelectric (FE)-to-antiferroelectric (AFE) transition behaviors were observed in Bi1-δFe0.95Mn0.05O3 (100)-textured films with a carefully controlled Bi deficiency concentration δ. Raman spectra revealed an orthorhombic structural transition induced by Mn substitution. The polarization-elec…
Functionalized graphene promises to become a key component of novel solar cell architectures, owing to its versatile ability to act either as transparent conductor, electron acceptor, or buffer layer. In spite of this promise, the solar energy conversion efficiency of graphene-based devices falls short of the performa…
A facile route for the synthesis of high-quality Fe3O4 nanoparticles (FNPs) has been successfully confirmed by employing a co-precipitation technique and then was stabilized onto wool fabric through a simple “impregnating” process. Here, the synergistic effect of BTCA and synthesized FNPs on magnetic and antifungal ch…
Uniformly aligned ZnO nanorod (NR) arrays grown on GaN quantum dots (QDs) as preferred nucleation sites are imperative for designing field emission emitters, ultraviolet photodetectors and light-emitting diodes for a wide range of new optoelectronic applications. In a recent study (2015 Nanotechnology 26 415601), Qi e…
Porphyrins are a ubiquitous large class of naturally occurring macrocyclic compounds with many significant biological representatives comprising heme and chlorophyll. Some novel adaptable methods for the synthesis of free-based porphyrins as promising sensitizers for the use in photo-dynamic therapy by the virtue of t…
ABSTRACT The novel inorganic SiO2–MgO–CaO whiskers (SMCWs) were incorporated into nano hydroxyapatite (HA) contained polylactic acid (PLA) system to prepare the reinforced PLA/HA/SMCWs nanocomposite. Maleic anhydride grafted PLA (PLA‐g‐MAH) was then used to modify the interface between filler and matrix. The morpholog…
The Hall effect and the diagonal resistance, which indicates a residual resistivity ρxx≈h/4e2, are experimentally examined over the p ↔ n transition about the nominal neutrality point in chemical vapor deposition (CVD) grown graphene. A distribution of neutrality potentials is invoked in conjunction with multi-carrier…
Ultraviolet ozone (UVO) surface treatment of graphene changes its sp 2 -hybridized carbons to sp 3 -bonded carbons, and introduces oxygen-containing components. Oxidized graphene has a finite energy band gap, so UVO modification of the surface of a four-layered graphene anode increases its surface ionization potential…
Monolayer black phosphorus (MBP) is a strong candidate for applications in emerging electronic devices. In this work, we report theoretical calculations of impurity limited carrier mobility of MBP using a state-of-the-art first principles quantum transport method where density functional theory is carried out within n…
In situ Ti2AlC/TiAl composite was first fabricated by reactive hot-pressing technique at low temperature of 1150°C for 2 h using Ti3AlC2 and Ti–Al alloy powders. The composite with fine-grained structure consisted of TiAl, Ti3Al and Ti2AlC phases. The Vickers hardness, flexural strength and fracture toughness of the T…
Ultraviolet (UV) micro-Raman measurements are reported of diamond grown on GaN using chemical vapor deposition. UV excitation permits simultaneous investigation of the diamond (D) and disordered carbon (DC) comprising the polycrystalline layer. From line scans of a cross-section along the diamond growth direction, the…
