The synthesis of a series of (formazanate)boron difluorides and their 1-electron reduction products is described. The neutral compounds are fluorescent with large Stokes shifts. DFT calculations suggest that a large structural reorganization accompanies photoexictation and accounts for the large Stokes shift. Reductio…
Site engineering has been employed to modulate the piezoelectric activity of high temperature (1 -x)Bi1.05Fe1-yScyO3-xBaTiO3 lead-free ceramics fabricated by a conventional solid-state method together with a quenching technique. The effects of x and y content on the phase structure, microstructure, and electrical prop…
We report the rationalised design of aluminium initiators and their application for ROP of rac-lactide (rac-LA). A very minor change to the ligand backbone (imine reduction) to give secondary amines was found to have a dramatic effect on activity and selectivity with isotactic PLA being realised.
A long-lived dual phosphorescence triplet photosensitiser: for TTA upconversion and PDT.
The co-modification of LSMO 4 electrode with SDC and NiO is found to increase its oxygen reduction reaction and fuel electro-oxidation catalytic activity, thus the symmetrical SOFC performance.
Amorphous MoSx thin-film-coated carbon fiber paper as a binder-free 3D electrode was synthesized by a facile hydrothermal method. The maximum specific capacitance of a single electrode was 83.9 mF cm(-2), while it was 41.9 mF cm(-2) for the symmetric device. Up to 600% capacitance retention was observed for 4750 cycle…
Recently, self-assembling small dendrimers into supramolecular dendritic systems offers an alternative strategy to develop multifunctional nanoplatforms for biomedical applications. We herein report a dual-responsive supramolecular PEGylated dendritic system for efficient platinum-based drug delivery and near-infrared…
Polyacrylamide embedded silver nanoparticles were synthesized from silver salts in a solvent-free fashion by ball milling mechanochemistry, with lignin as a biodegradable reducer, and used as highly efficient antibacterial plugs.
Four common size analysis techniques were applied to engineered silica nanoparticles suspended in purified water, in physiological buffer and in cell culture medium, and the results were compared using uncertainty estimates.
Efficient delivery of stabilized nucleic acids (NAs) into cells and release of the NA payload are crucial points in the transfection process. Here we report on the fabrication of a nanoscopic cellular delivery carrier that is additionally combined with a label-free intracellular sensor device, based on biocompatible f…
Polyhydroxyalkanoates were first greatly stabilized by an acid wash, and then reaction extruded to produce blends with enhanced interfacial adhesion.
PdO/CeO2 nanosheets encapsulated by a monolayer of a continuous and dense HZSM-5 zeolite membrane were prepared by a facile in situ hydrothermal growth process and used as a highly efficient and thermally stable catalyst for methane combustion. Uncoated PdO/CeO2 suffered severe sintering at high temperature or high ox…
A series of new organometallic carbosilane dendrimers (first and second generation) and the corresponding non-dendritic mononuclear based on ruthenium arene fragments are described. The metallodendrimers were prepared by reactions of the precursor [Ru(η(6)-p-cymene)Cl2]2 with carbosilane dendrimers functionalized with…
Aqueous hybrid capacitors (HCs) suffer from sacrificed power density and long cycle life due to the insufficient electric conductivity and poor chemical stability of the battery-type electrode material. Herein, we report a novel NH4-Co-Ni phosphate with a stable hierarchical structure combining ultrathin nanopieces an…
Some functionalised dipeptides can form hydrogels when salts are added to solutions at high pH. We have used surface tension, conductivity, rheology, optical, confocal and scanning electron microscopy, (1)H NMR and UV-Vis spectroscopy measurements to characterise fully the phase behaviour of solutions of one specific…
We describe a procedure to cheaply manipulate comparatively large amounts of mill scale into Fe 2 O 3 with a porous/hollow morphology with outstanding electrochemical energy storage performance.
Astaxanthin nanoformulation was found appropriate in all measures with strong antioxidant activity against H 2 O 2 induced oxidative stress in PC12 cells. Biodistribution and brain delivery was also found to be superior to conventional dosage form.
3D LSG/CoNi 2 S 4 //LSG interdigitated microelectrodes have been firstly developed by a facile, scalable and low cost process for all-solid-state, flexible integrated asymmetric micro-supercapacitors.
This study was designed to assess the efficacy of hyaluronan (HA) functionalized well-aligned nanofibers of poly-l-lactic acid (PLLA) in modulating the phenotypic expression of vascular smooth muscle cells (vSMCs) for blood vessel regeneration. Highly aligned HA/PLLA nanofibers in core-shell structure were prepared us…
A rationally designed carbon aerogel with a unique cellular structure was obtained, consisting of 1D carbon nanofibers and 2D carbon sheets, and used as an efficient versatile adsorbent and an ideal template for in situ growth of MnO 2 nanosheets to obtain an electrochemically active hybrid aerogel.
