Uniform silica-protected and N-doped TiO 2 hollow spheres are facilely prepared using inorganic–organic silica as self-removed templates.
Three-dimensional (3D) TiO2-SnO2-graphene aerogels (TTGs) were built up from the graphene oxide nanosheets supported with both TiO2 and SnO2 nanoparticles (NPs) via a facile hydrothermal assembly process. The resulting TTGs exhibit a 3D hierarchical porous architecture with uniform distribution of SnO2 and TiO2 NPs on…
CZTS nanorods with a kesterite structure and a diameter of 6.8 nm were successfully synthesized using a nanocasting route. A sol–gel process is proposed for the impregnation and crystallization of the quaternary compound during nanocasting synthesis.
The diboraanthracene bis(oxyquinolinato) complexes were employed for the construction of efficient green OLEDs.
Highly crystalline Fe 2 GeS 4 nanocrystals were synthesized via a facile, solvent-free mechanochemical process. The post-annealed Fe 2 GeS 4 nanocrystals showed an absorption edge at 1.43 eV and a PL emission at 1.41 eV.
Hierarchical ZnFe 2 O 4 /graphene hybrid films are deposited on copper foils as a promising binder-free lithium-ion battery anode.
In an effort to impart light gas (i.e., H2 and He) barrier to polymer substrates, thin films of polyethylenimine (PEI), poly(acrylic acid) (PAA), and montmorrilonite (MMT) clay are deposited via layer-by-layer (LbL) assembly. A five "quadlayer" (122 nm) coating deposited on 51 μm polystyrene is shown to lower both hyd…
The regeneration of fibrocartilage at the tendon-bone insertion site in rotator cuff tears (RCTs) is challenging due to the complexity of its composition and mechanical properties. In this study, hierarchical, stretchable and stiff fibrous scaffolds composed of microfibers of poly(ε-caprolactone) (PCL) and nanofibers…
A high V OC of 1V is achieved in the bulk heterojunction solar cell using the solution-processed small molecule donor p-DTS(FBTTh 2 ) 2 and indene-C60 bis-adduct acceptor.
The Gaussian Diffusion Approximation proposes that the distribution of displacements Δx for a particle diffusing through a complex fluid has a Gaussian dependence on Δx. We demonstrate from experimental evidence and computer simulations that this approximation is generally incorrect in complex fluids. As a result, exp…
Abstract A new perovskite‐like coordination polymer [(CH3)2NH2][Cd(N3)3] is reported which undergoes a reversible ferroelastic phase transition. This transition is due to varied modes of motion of the [(CH3)2NH2]+ guest accompanied by a synergistic deformation of the [Cd(N3)3]− framework. The unusual two‐staged switch…
BiOCl nanosheets with different thickness have been successfully synthesized via a solvothermal process with the mediation of metal ions (Fe 3+ , Co 2+ and Na + ) and exhibited thickness-dependent photosensitization activity for RhB degradation.
(a) TEM image of FeS 2 /RGO-C; (b) curves of friction reduction properties for (1) the paraffin oil, (2) oil with 7 wt% RGO, (3) oil with 7 wt% FeS 2 , (4) oil with 7 wt% FeS 2 /RGO-A, (5) oil with 7 wt% FeS 2 /RGO-B, (6) oil with 7 wt% FeS 2 /RGO-C.
The degradation pathway of 2,4-DCP was deduced by reference to similar studies of other scholars and mass spectrometry analysis.
We study the electronic structure and lattice dynamics in the ferromagnet MnBi using first-principles calculations and a tight-binding model. The band structure around the Fermi level is dominated by Bi-p states which are the primary contributors to the magnetic anisotropy energy in the low temperature structure. A ti…
The inhalation of zinc oxide engineered nanomaterials (ENMs) has been linked to cardiorespiratory dysfunction in mammalian models but the effects of aquatic ENM exposure on fish have not been fully investigated. Nano-zinc oxide (nZnO) is widely used in consumer products such as sunscreens and can make its way into aqu…
A series of [Mn(Ln)Cl] complexes 1–4 are obtained and shown to be effective catalysts in epoxide and anhydride ring-opening copolymerizations.
An ideal scaffold for bone tissue engineering should have interconnected porous structure, good biocompatibility, and mechanical properties well-matched with natural bones. Collagen is the key component in the extracellular matrix (ECM) of natural bones, and plays an important role in bone regeneration. The biological…
Chitosan is a desirable material for several reasons, including its biocompatibility, biodegradability, non-toxicity, and excellent absorption. Rapid progress in material science has resulted in the development and widespread use of chitosan in the textile industry primarily because it is polycationic and can inhibit…
Abstract A molybdenum L‐edge X‐ray absorption spectroscopy (XAS) study is presented for native and oxidized MoFe protein of nitrogenase as well as Mo‐Fe model compounds. Recently collected data on MoFe protein (in oxidized and reduced forms) is compared to previously published Mo XAS data on the isolated FeMo cofactor…
