Mirror-twin induced bicrystalline inAs nanoleaves

This study reveals the formation of bicrystalline InAs nanoleaves driven by catalyst energy minimization. The relatively low-energy {122} or {133} mirror twins lead to the identical lateral growth of twinned structured, which results in the symmetrical formation of nanoleaves. A bio-inspired nanotechnology design can be created for future electronic or optoelectronic devices by correlating the structure of InAs nanoleaves in the nanoworld and that of real leaves in the natural world.

Novel synthesis of N-doped graphene as an efficient electrocatalyst towards oxygen reduction

N-doped porous graphene was successfully synthesized by a simple and scalable bottom-up method. The subsequent annealing step promoted the conversion of N-containing species from pyrrolic N to pyridinic N, leading to a remarkably improvement of electrochemical performance towards the oxygen reduction reaction. The theoretical simulations indicated that the rapid H transfer and thermodynamic stability of six-membered N structure boost the transformation of N-containing species.

An approach to construct nanorattles based on upconverting lanthanide-doped fluorides

We developed a novel “ship-in-a-bottle” method to fabricate upconverting (UC) luminescent nanorattles by incorporating lanthanide-doped fluorides into hollow mesoporous silica. Furthermore, we employed these nanorattles in proof-of-concept UC-monitoring drug release by utilizing the energy transfer process from UC fluorides to DOX, thus revealing the great potential of the nanorattles as efficient cancer theranostic agent.

Porous spinel cobalt manganese oxides as efficient oxygen reduction reaction electrocatalysts

Three type of spinel CoxMn3-xO4 (CMOs), cubic Co2MnO4 nanorods, tetragonal CoMn2O4 microspheres, and tetragonal CoMn2O4 cubes, were successfully obtained and exhibit brilliant oxygen reduction reaction (ORR) electrocatalysis along with high stability. In particular, the cubic Co2MnO4 nanorods show the best performance with an onset potential of 0.9 V and a half-wave potential of 0.72 V and superior stability after a continuous operation time of 10,000 seconds.

Vertically stacked holey graphene/polyaniline heterostructures with enhanced energy storage for on-chip micro-supercapacitors

Micro-supercapacitors with holey graphene/polyaniline heterostructures were successfully designed and constructed. The capacitance and rate capability of micro-supercapacitors can be improved largely by introducing the holy graphene intermediate layer. This improvement is mainly due to the unique structure of holy graphene, which not only increases the electrical transport of electrodes, but also results in three-dimensional transport for electrolyte ions. Highly efficient energy storage is, thus, realized.

According to a pair of studies, simultaneous inhibition of angiopoietin-2 (Ang-2) and the vascular endothelial growth factor (VEGF) pathway in mouse models of glioblastoma was associated with slowed tumor growth, enhanced blood vessel normalization, and extended survival compared with either Ang-2 or VEGF inhibition alone, and the combination therapy was also associated with an increased fraction of tumor-associated macrophages that exhibited an anti-tumor phenotype.

External stimuli controlled multiferroic charge-transfer crystals

A segregated stack design was carried out to control charge-transfer multiferroic crystal nanostructures, where the interfacial structure and dimensions of the crystals are controlled by all conjugated block copolymer doping to modify the donor-acceptor stacks. Room temperature ferroelectricity and anisotropic magnetism are shown in charge transfer crystals, which can be further controlled by photoexcitation and charge doping through ionic liquids. Furthermore, electric field dependent magnetization reveals the ME coupling effect of charge transfer crystals.

Protease-activated receptors differentially regulate endothelial nitric oxide synthase

It has been established that the activation of protease-activated receptor-2 (PAR-2) phosphorylates endothelial nitric oxide synthase (eNOS)-Ser-1177 through a distinct signaling pathway that leads to the production of the potent vascular vasodilator nitric oxide (NO), while PAR-1 activation phosphorylates eNOS-Thr-495 and decreases NO production through a separate pathway. In this study, we have identified a variance in PAR coupling to the signaling pathways that regulate eNOS phosphorylation and NO production in adult human endothelial cells.

Cardioprotective effects of lysyl oxidase inhibition

The collagen cross-linking enzyme, lysyl oxidase (LOX), is elevated in many cardiac diseases and is associated with fibrosis. Here, we report that inhibition of LOX activity provided significant cardioprotection in a rat model of chronic volume overload (VO) stress. Rats with 8 weeks of established VO-induced disease were treated with a LOX inhibitor for 6 wks. LOX inhibition completely reversed cardiac fibrosis and improved both systolic and diastolic heart function.

Synthesis of pure phase Mg1.2Ti1.8O5 and MgTiO3 nanocrystals for photocatalytic hydrogen production

As hydrogen evolution photocatalyst, pure phase Mg1.2Ti1.8O5 and MgTiO3 nanocrystals were prepared for the first time. In comparison with pure MgTiO3 nanocrystals, the as-prepared Mg1.2Ti1.8O5 nanocrystals present four times promoted photocatalytic hydrogen production activity. Photoelectrochemical results indicated that the enhanced photocatalytic activity of Mg1.2Ti1.8O5 could be attributed to the fast photo-electrons transfer, higher carrier density and efficient charge separation.
