We report a universal strategy for the hierarchical assembly of nanoparticles on various 2D materials, resulting in functional 0/2D nanohybrids holding great promise in catalysis, energy storage, and chemical and biological sensing.
New carbazole-triphenylamine end-capped di(thiophen-2-yl)benzothiadiazole showed high thermal and electrochemical stability, and great potential as a solution processed hole-transporting non-doped red emitter for OLEDs. A pure red device with CIE coordinates and a high luminance efficiency of (0.66, 0.33) and 3.97 cd…
Preserved high first triplet energy levels and improved electrical properties of two donor-acceptor type carbazole-phosphine oxide hosts were achieved through short-axis substitution to realize efficient PHOLEDs with extremely low driving voltages of 2.6 V for onset and <3.2 V at 100 cd m(-2).
We demonstrate numerically that photonic crystal dye-sensitized solar cells (DSSCs) can provide at least a factor of one-third enhancement in solar light absorption and power conversion efficiency relative to their conventional counterparts. Our design consists of a lattice of modulated-diameter TiO2 nanotubes filled…
Over the past decade, the low intensity of extreme ultraviolet (EUV) light sources has been the most critical issue in the development of a promising, next-generation, high volume manufacturing (HVM) EUV lithography method. Specifically, enhancing the sensitivity of EUV resists to compensate for this low intensity is…
The syntheses of H2-phbpz, [Cu2(phbpz)]·2DEF·MeOH (CFA-2) and [Ag2(phbpz)] (CFA-3) (H2-phbpz = 3,3',5,5'-tetraphenyl-1H,1'H-4,4'-bipyrazole) compounds and their crystal structures are described. The Cu(I) containing metal-organic framework CFA-2 crystallizes in the tetragonal crystal system, within space group I4(1)/a…
A facile approach was developed to prepare well-dispersed ionic liquid functionalized graphene composites using 1-butyl-3-methylimidazolium 2-amino-3-mercaptopropionic acid salt ionic liquid as a reducing reagent and functionalization reagent. The resulting material showed excellent electrochemical activity to catecho…
The crystal structures are reported of four gallium(III) complexes based on two pairs of 6-substituted-6-amino-perhydro-1,4-diazepine ligands, together with a study of their solution structures examined by (1)H and (71)Ga NMR spectroscopy. In each case, the ligand adopts a twisted chair conformation that creates a fac…
Porous activated graphene sheets have been for the first time exploited herein as encapsulating substrates for lithium ion battery (LIB) anodes. The as-fabricated SnO2 nanocrystals-porous activated graphene sheet (AGS) composite electrode exhibits improved electrochemical performance as an anode material for LIBs, suc…
Small amyloid-β (Aβ) oligomers have much higher membrane affinity compared to the monomers, but the structural origin of this functional change is not understood. We show that as monomers assemble into small n-mers (n < 10), Aβ acquires a tertiary fold that is consistent with the mature fibrils. This is an early and d…
Although the physical mechanism of light trapping property of butterfly wings is well understood, it remains a challenge to create artificial replicas of these natural functional structures. Here, we synthesized a SiO2 inverse replica of a light trapping structure in butterfly wing scales using a method combining a so…
Mesoporous SnO2 with a high surface area of 292.7 m(2) g(-1) has been successfully synthesized via a low-cost NH4Cl-based ionothermal route. When evaluated as a gas sensor, impressive performances towards N2H4 and HCHO are achieved owing to its excellent chemical reactivity towards oxygen.
OBJECTIVES: Current drug therapies for psychological disorders, such as anxiety, are not as effective as expected, and it has been shown that zinc supplements, such as zinc oxide (ZnO), can influence anxiety. ZnO nanoparticles (ZnO NPs) are among the most used nanomaterials produced and applied in many products. MATER…
We have shown, for the first time, that a three component system is capable of aligning gold nanorods (AuNRs) through supramolecular host-guest interactions leading to control over AuNR end-to-end assembly. Viologen end-functionalised AuNRs were prepared that were capable of selectively binding to a cucurbit[8]uril (C…
A strategy for responsively toughening an injectable protein hydrogel has been implemented by incorporating an associative protein as the midblock in triblock copolymers with thermoresponsive poly(N-isopropylacrylamide) (PNIPAM) endblocks, producing materials with a low yield stress necessary for injectability and dur…
In the present work, we show that Cu(0)-mediated controlled radical polymerization is a suitable method to synthesize high molar mass polystyrene-b-poly(ethoxy ethyl acrylate) PS-b-PEEA diblock copolymers. This method, applied at room temperature, is mandatory for complete preservation of ethoxy ethyl protecting group…
A colorimetric probe for the detection of copper(II) ions in aqueous media by the naked eye has been developed based on a supramolecular complex comprised of a cationic polythiophene derivative and ATP with a detection limit as low as 0.05 mM.
A novel surface-enhanced Raman scattering (SERS) method is demonstrated to detect L-histidine based on DNAzyme which can specifically recognize L-histidine. Through a target recycling cascade amplification strategy, the DNAzyme-based SERS sensing system affords very high sensitivity for L-histidine with a detection li…
Natural radiation is the largest contributor to the collective radiation dose to the world population. Relatively constant exposure to the population at a location for a considerable period of time is the cause of radiation hazard to the population. The earth is radioactive since its creation. The radioactive elements…
The inverted micellar cubic Fd3m phase has attracted significant interest in drug delivery and is also of special biological relevance in the early steps of fat digestion. Applying small angle X-ray diffraction (SAXD) the stability of the Fd3m phase with respect to the chain configuration has been examined. In particu…
