Endogenous growth of 2D boehmite nanosheets on a 3D Al-fiber network via steam-only oxidation has been demonstrated, showing substantial potential for structured catalysts verified by several hot-topic reactions.
A series of five benzoyltrifluoroacetone Er( iii ) complexes with various azacyclo-auxiliary ligands exhibit unique NIR luminescence and may be potential materials in optical amplifiers.
Thermally stable ferrocene-DPP dyads exhibit non-zero dipole moments as well as negative solvatochromism and show structure dependent second-order nonlinear polarizabilities.
The effects of regioisomerism on the self-assembly and luminescence of polycatenars have been investigated.
A microporous polymer with sulfide and thiol groups was synthesized using the thiol-yne reaction. Au nanoparticles were prepared by in situ reduction reaction inside the polymer and were found to be well dispersed. The Au-containing polymer showed catalytic activity in the reduction of 4-nitrophenol.
The multifunctionalities of near-infrared upconversion luminescence, optical temperature sensing and long persistent luminescence are demonstrated in La 3 Ga 5 GeO 14 :Cr 3+ ,Yb 3+ ,Er 3+ and their potential coupling are discussed in detail.
Contrary to common belief, hollow precipitation tubes form in the absence of silicate if sodium hydroxide solution is injected into solutions of various metal ions. In many cases, the growth speed has a power law dependence on the flow rate. For vanadyl, we observe damped oscillations in the tube height.
We report that decomposition pathway of Ca(BH4)2 can be efficiently controlled by reaction temperature. That is, it decomposes into CaB6 at a lower temperature range of 320 to 350 °C, but into amorphous boron at 400 to 450 °C. We identified the formation of CaB2H6 as the crucial intermediate step on the way to CaB6 th…
Hierarchically nanoporous La 1.7 Ca 0.3 Ni x Cu 1−x O 4−δ layered perovskite oxides prepared by a citrate-modified evaporation-induced self-assembly method are demonstrated to be potential cathodes for Ni–YSZ anode supported IT-SOFCs with high power density.
Graphene oxide has been extracted from low grade coal or wood charcoal. The clenched and open fist forms of GO are related to pH and enable GO to act as Trojan horse in carrying and delivering a drug molecule under a physio-compatible environment.
Cardiomyogenesis and neurogenesis were tested on polyaniline films. Polyaniline in pristine forms without any further modification can be applied in a variety of biomedical fields.
Composites of sulphur polymers with nanoparticles such as PbS, with tunable optical properties are reported. A hydrothermal route incorporating pre-formed nanoparticles was used, and their physical and chemical properties evaluated by transmission and scanning electron microscopy, thermogravimetric and elemental analy…
Preparation of raspberry-like particles (RPs) and the subsequent fabrication of superhydrophobic films with tunable adhesion derived from fluorinated RPs.
It is currently a very active research area to develop new types of substrates which integrate various nanomaterials for surface-enhanced Raman scattering (SERS) techniques. Here we report a unique approach to prepare SERS substrates with reproducible performance. It features silicon mold-assisted magnetic assembling…
Promoting the effect of indium( iii ) on activated carbon supported gold–cesium( i ) catalyst in acetylene hydrochlorination.
Adhirons are robust, well expressing, peptide display scaffold proteins, developed as an effective alternative to traditional antibody binding proteins for highly specific molecular recognition applications. This paper reports for the first time the use of these versatile proteins for material binding, and as tools fo…
A novel kind of BaFe 12 O 19 /Fe 3 C/CNTs composite was developed by the acetylene chemical vapor deposition process. The composites perform great improvement in the microwave absorbing properties compared with pure BaFe 12 O 19 ferrite in 2–18 GHz range.
Hydrogel nanofibers with high swelling ratio are prepared by electrospinning polyvinylpyrrolidone and poly(acrylic acid) blend followed by subsequent heat treatment.
An efficient surface enhanced Raman scattering (SERS) substrate of graphene-isolated Ag nanoparticle (G/AgNP) has been developed by using excimer laser to ablate the ordered pyrolytic graphite in high vacuum onto Ag nanoparticles.
In this paper, we reported a facile strategy to fabricate a PDMS film-coated Au nanoparticle monolayer film (Au MLF) composite substrate for improving SERS detection of aromatic molecules in water and in the atmosphere.
