SiC, Al2O3 and Graphene are the major reinforcement in aluminium-based composites, which have been developing rapidly in recent years. This paper focuses on the effect of ball milling & reinforcement percentage on mechanical properties of aluminium alloy metal matrix composites. The average particle size of matrix met…
Reactive oxygen species (ROS) are involved in the pathophysiology of ischemia/reperfusion injury. To protect mouse hepatocytes from ischemia/reperfusion injury, we prepared two different sizes of citric acid-protected platinum nanoparticles (Pt-NPs), which exhibited ROS-scavenging activities and selective delivery to…
Traditional asphalt mixture design practices recognize the need for laboratory parameters, which relate to field performance throughout the life of the pavement. However, many design methodologies consider volumetric proportions and strength characteristics of the mixtures, which may not provide adequate insight into…
Investigation of the effect of Ti surface roughness on the formation, organization, hexagonal arrangement and length of TiO 2 NTs.
Previous studies of methacrylate based nanoparticle have demonstrated the excellent pattern forming capability of these hybrid materials when used as photoresists under 13.5 nm EUV exposure. HfO2 and ZrO2 methacrylate resists have achieved high resolution (∼22 nm) at a very high EUV sensitivity (4.2 mJ/cm2). Further i…
C60 fullerenol was found to be a highly active, selective and stable catalyst for cycloaddition between CO2 and epoxides to produce various cyclic carbonates with excellent yields (89-99%). A solid/liquid interfacial hydrogen-bond assisted mechanism was proposed to account for its high efficiency.
A Michael addition activated chemodosimeter was designed with a carbazole donor and a dicyanovinyl acceptor. The design features an acceptor–donor–acceptor (A–D–A) molecular configuration and the cyanide addition on the electron-deficient alkene bridge breaks the donor–acceptor interaction and produces a blue shift in…
Solution-processable hole-transporting layers (HTLs) capable of cross-linking are especially important in solution-processed organic light-emitting diodes (OLEDs) to achieve multilayer structures with separated charge-transporting layers and emitting layers. In this work, we report the first example of photo cross-lin…
Delafossite CuFeO2 hexagonal platelets/rings and graphene composites were synthesized by a low temperature hydrothermal method. The formation mechanism of CuFeO2 hexagonal platelets/rings follows the combined effects of both GO and NaOH. The obtained composites as anode materials display a good battery performance wit…
Three-dimensional (3D) nanoporous architectures, possessing high surface area, massive pores, and excellent structural stability, are highly desirable for many applications including catalysts and electrode materials in lithium ion batteries. However, the preparation of such materials remains a major challenge. Here,…
The phenol mineralization ability of TCNQ–g-C 3 N 4 is enhanced by the lower valence position and the charge transfer.
Heavy metal recovery by the fabrication of mixed-Fe 3 O 4 @SiO 2 /metal oxide magnetite photocatalysts from electroplating wastewater.
A WO 3 –WO 3 ·H 2 O mixture phase hollow sphere photocatalyst created through a template-free process demonstrated enhanced visible light photocatalytic activity.
In this work, we report some preliminary results concerning the fabrication of quaternary semiconductor Cu2ZnSnS4 (CZTS) thin films on a flexible substrate through the simultaneous electrodeposition of elements having different standard electrochemical potentials. CZTS thin films were obtained by potentiostatic deposi…
A charge-transfer-featured naphthalimide derivative with a small exchange energy but a lower lying (3)ππ* state than (3)CT state is found to contribute to triplet harvesting through a P-type rather than an E-type delayed fluorescence, and could act as a quite promising host to achieve highly efficient OLEDs.
This letter presents the design and results of low-loss discrete dielectric flat reflectarray and lens for E-band. Using two different kinds of feed, 3-D-pyramidal (wideband) horn and 2 × 2 planar microstrip array (narrowband) antenna, the radiation performances of the two collimating structures are investigated. The…

Molybdenum (Mo) is the most used back contact in Cu2ZnSn(S1-xSex)4 based solar cells. However, it has been suggested recently that Mo is not stable at the interface with Cu2ZnSn(S1-xSex)4. In addition, to the best of our knowledge, no experimental study has been carried out so far to test whether solar cells built on…
Here, we report the facile synthesis of a highly ordered luminescent ZnO nanowire array using a low temperature anodic aluminium oxide (AAO) template route which can be economically produced in large scale quantity. The as-synthesized nanowires have diameters ranging from 60 to 70 nm and length ∼11 μm. The photolumine…
Adsorption of two representative anionic dyes (Acid Fuchsine (AF) and Acid Orange II (AO)) using MCM-41 functionalized with amine groups in a mesoporous silica framework (NH 2 –MCM-41) as the adsorbent was investigated.
