A methodology to delimit the large Stokes shifts in the donor–acceptor (D–A) design by studying D and A in para -relationship with solution processed blue OLED device application is reported.
A thermally activated delayed fluorescence material 2,6-bis(9,9-diphenylacridin-10(9H)-yl)pyrazine was designed and synthesized. The twisted configuration made it possesses very small singlet-triplet splitting. A red electroluminescent device based on this new host material is able to achieve ∼26% external quantum eff…
Low cost Co 3 O 4 /N-KB was proposed as a high performance catalyst for Al-air battery. The full battery using this catalyst in air electrode displayed a high discharge voltage plateau of ~1.52 V, comparable to that of the commercial Pt/C (20wt%).
A tandem Diels–Alder addition and lactonisation between bio-derivable itaconic anhydride and furfuryl alcohol can be used to prepare novel monomers for ROMP.
Improved structure–property relationships for activated carbon were obtained by devising realistic, large-scale, structural models.
Three highly porous Zr(iv)-based metal-organic frameworks, UBMOF-8, UBMOF-9, and UBMOF-31, were synthesized by using 2,2'-diamino-4,4'-stilbenedicarboxylic acid, 4,4'-stilbenedicarboxylic acid, and combination of both linkers, respectively. The mixed-linker UBMOF-31 showed excellent hydrogen uptake of 4.9 wt% and high…
Advances in shape-dependent nanoparticle (NP) research have prompted a close scrutiny of the behaviour of nanostructures in vitro and in vivo. Data pertaining to cellular uptake and site specific sequestration of different shapes of NPs will undoubtedly assist researchers to design better nano-probes for therapeutic a…
Pd nanoparticles with a trace of SnO 2 are prepared on a novel graphene-based porous carbon and they show dramatically improved electrocatalytic activity and durability for methanol oxidation compared to porous carbon supported Pd catalysts with SnO 2 or graphene-based porous carbon supported Pd catalysts without SnO…
Concave nanocubes are enclosed by high-index facets and have negative curvature; they are expected to have enhanced reactivity, as compared to nanocubes with flat surfaces. Herein, we propose and demonstrate a new strategy for the synthesis of concave Pt nanocubes with {hk0} high-index facets, by using a hydrogen adso…
The supramolecular chemistry of the bis-imidazole ligand 1,4-bis(imidazol-1-ylmethyl)benzene, popularly known as bix, has been explored by various researchers in order to synthesize functional coordination polymers (CPs). The flexibility of the bix ligand, its unpredictable conformation and its coordination behaviour…
Herein, we provide a new easy-to-do protocol for preparing luminescent rubber-like materials based on a wide palette of compounds, such as small-molecules, quantum dots, polymers, and coordination complexes.
Electrostatic interaction of chitosan-based silver nanoparticles with human serum albumin leads to inhibition of fibrillogenesis.
PURPOSE: Chitin is a potent adjuvant in the development of immune response to inhaled allergens in the airways. According to other studies, chitin is known as multi-faced adjuvants which can induce Th2 responses. Recently, we found that TNF-α is a key mediator in the development of Th2 cell response to inhaled allerge…
In a normal electrochemical metallization (ECM) switch, electrochemically active metals, such as Ag and Cu are used to provide mobile ions for the conducting filament. In both ECM and valence change memory (VCM) devices, platinum group metals, such as Pt and Pd, are typically used as the counter electrode and assumed…
A method is presented to partition the 3N-dimensional space of a many-electron wavefunction into hyper-regions related by permutation symmetry. These hyper-regions represent unit cells, or "tiles" of the wavefunction from which the wavefunction may be regenerated in its entirety upon application of the set of permutat…
Reduced graphene oxide (r-GO)powder has been prepared from coconut shells by carbonization process at 400°C for 3, 4 and 5 hours.Theresulted sample mass was reduced to be 60% relativelycompared to the starting material. The longer heating duration has also led to the rGO with reduced crystalinity according to the X-ra…
A DFT based characterization of tungsten oxide supported on amorphous hydroxylated silica is presented.
High activity of post-synthetically synthesized Sn-beta, producing novel caprolactone polymer building blocks, is demonstrated in Meerwein-Ponndorf-Verley (MPV), Oppenauer (OPO), Baeyer-Villiger (BV) and cascade reactions thereof with biomass-derived molecules.
Porous gold nanoparticle/graphene oxide composites obtained through freeze-drying method show superior continuous catalytic performance in the reduction of 4-nitrophenol.
The development of efficient oxygen reduction reaction (ORR) electrocatalysts composed of low cost and earth abundant elements is imperative for several energy systems.
