Core/shell CdS/Bi 2 S 3 heterostructures have been synthesized through in situ cation-exchange method. These heterostructures exhibit enhanced photostability and visible light photocatalytic activity.
Charge generation and recombination dynamics in a blend film of a crystalline low-bandgap polymer, poly[(4,4-bis(2-ethylhexyl)dithieno[3,2-b:2',3'-d]silole)-2,6-diyl-alt-(4,7-bis(2-thienyl)-2,1,3-benzothiadiazole)-4,7-diyl] (PSBTBT), and [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) were studied by transient absor…
Nanodiamonds (NDs) and carbon-dots (CDs) suspensions exhibit significant NLO response under both ps and ns laser excitation. NDs exhibit important optical limiting action under nanosecond visible (532 nm) and infrared (1064 nm) laser excitation.
Biopolymer-based nanogels have great potential in the field of tissue regenerative medicine. In this work, a magnetic biopolymer nanogel via specific nucleobase pairing was developed for vectoring delivery of cell growth factors. The biopolymer based nanogels chitosan and heparin were established by the Watson-Crick b…
The light absorption performance, surface chemistry and photoreactivity of the MWCNT@TiO 2 core–shell in CO 2 reduction were studied.
Magnetic Fe3O4 nanoparticles embedded in graphene oxide (Fe3O4@GO) behave as a highly efficient and reusable heterogeneous nanocatalyst for alkene hydrogenation in EtOH at 80 °C temperature using hydrazine hydrate as the hydrogen source to deliver the corresponding alkanes in good to excellent yields together with hig…
Silver nanoparticles-anchored reduced graphene oxide (Ag-RGO) is prepared by simultaneous reduction of graphene oxide and Ag(+) ions in an aqueous medium by ethylene glycol as the reducing agent. Ag particles of average size of 4.7 nm were uniformly distributed on the RGO sheets. Oxygen reduction reaction (ORR) is stu…
A label-free approach to selective detection of 3,3',4,4'-tetrachlorobiphenyl (PCB77) using aptamer modified silica-Au/core-shell nanoparticles (denoted as SiO2@Au core/shell NPs) through surface enhanced Raman scattering (SERS) spectroscopy was proposed. The devised system consisted of SiO2@Au core/shell NPs fixed on…
The structure of native squid pen (gladius) was investigated in two different species on different length scales. By combining microscopy, atomic force microscopy (AFM), and X-ray diffraction, the experiments probed length scales from millimetres down to nanometres. The gladii showed a hierarchical, self-similar struc…
Fast and selective laser sintering is efficient for the treatment of TiO 2 nanoparticle film for flexible DSC applications.
Templated from the bristles on Papilio maacki wings, single porous SnO 2 microtubes (SPSMs) have been synthesized by soaking and sintering.
Sandwich-like hybrid nanosheets consisting of graphene wrapped SnO/SnO 2 nanocrystals anchored on graphene have been synthesized via a facile layer-by-layer self-assembly approach.
A robust and orthogonal approach to access modular block-copolymer poly(ionic liquid)s.
The copper–isonicotinate metal–organic frameworks [Cu(INA) 2 ] (INA = isonicotinate) (MOFs) has been prepared by a highly efficient and environmentally benign technique involving mixing and heating of solid reactants without milling. The adsorption of fluorescein dye on the as-synthesised [Cu(INA) 2 ] was also investi…
3D mesoporous BiOBr microspheres via a one-step solvothermal process without templates were synthesized. The as-synthesized material was characterized by XRD, XPS, FESEM, TEM, UV-Vis and nitrogen adsorption techniques. The photodegradation behavior of the non-steroid anti-inflammatory drug (NSAID) ibuprofen (IBP) in a…
Styrene was successfully hydrogenated to ethylbenzene in alcoholic suspensions of a Pd–TiO 2 photocatalyst.
PdNiP alloy nanoparticle networks (PdNiP NN) were prepared by simultaneous reduction of PdCl2, NiCl2 and NaH2PO2 with NaBH4via a gas-liquid interface reaction at room temperature using N2 bubbles. PdNiP NN had markedly higher activity and durability for ethanol oxidation than PdNi nanoparticle networks and PdNiP grain…
GO/noble metal (Au, Pt, and Pd) NP composites were synthesized and the corresponding NLO and optical OL properties were investigated.
In the study, an HPW–PDMAEMA–SiO 2 (phosphotungstic acid (HPW); poly- N , N -dimethylaminoethyl methacrylate (PDMAEAM)) catalyst was successfully synthesized.
So far, organic semiconductors have been mainly proposed as detectors for ionizing radiation in the indirect conversion approach, i.e. as scintillators, which convert ionizing radiation into visible photons, or as photodiodes, which detect visible photons coming from a scintillator and convert them into an electrical…
