Two new phosphorescent platinum( ii ) cyclometallates with flexible phenoxy moieties were prepared whose broad excimeric emissive states in the solid state allow the fabrication of high color-rendering two-emitter WOLEDs.
Recently, nanoscale (<100 nm) inorganic materials, especially spherical shaped zinc oxide (ZnO-QDs), have received a lot of attention from the broad community because of their potential utilization in various technologies.
A ternary nano-architectural photocatalyst has been designed to investigate whether the intrinsic magnetic property of photo-catalysts has an effect on the charge transfer and its photo-catalytic H2 evolution reaction (HER) properties under visible light irradiation. The electron transfer and visible-light-driven hydr…
Elemental sulfur was successfully impregnated in an activated carbon (AC) matrix obtained from sisal fibers.
It is found from the earlier studies that the structure-dependency of total π -electron energy Eπ heavily relies on the sum of squares of the vertex degrees of the molecular graph. Hence, it provides a measure of the branching of the carbon-atom skeleton. In recent years, the sum of squares of the vertex degrees of th…
An ultralight nickel scaffold is designed to enhance the electrochemical performance of NiCo 2 O 4 nanowire electrodes.
magnetic core and the current passing through the molecular system in the Coulomb blockade regime, thus showing that the use of graphene is a promising way forward in addressing single molecules.
Microparticulate drug delivery systems have been explored across the globe due to their various advantages. In 1987, Won developed microsponge systems (Micsys), also known as solid-phase porous microspheres, having numerous interconnected voids, which serve as non-collapsible residence for bioactive compounds. A Micsy…
Solution-processed oxo-functionalized graphene is used to substitute hydrophilic PEDOT:PSS as an anode interfacial layer for perovskite solar cells. The resulting devices exhibit a reasonable PCE of 15.2% and improved stability.
Based on a review analysis of empirical fuel cell polarization curve models in the literature, an improved model that can predict fuel cell performance with only measured current-voltage data is developed. The fitting characteristics of this new model are validated by fitting bench test data and road test data. In the…
Hollow PtAg alloy nanospheres were synthesized via galvanic replacement reaction between silver nanoparticles and K 2 PtCl 4 at 60 °C.
We report three hole transport materials featuring “X” swivel-cruciform structures for stable perovskite solar cells.
A screening procedure for identifying eletronically and structurally matched interfaces based on bulk properties is developed and applied to perovskite solar cells.
A Cd(II)-based metal-organic framework, [Cd2(DPDC)2(BTB)]∞ (Cd-MOF, DPDC = 2,2'-diphenyldicarboxylate and BTB = 1,4-bis(1,2,4-triazol-1-yl)butane) was successfully constructed via a hydrothermal reaction. Structural analysis shows that the synthesized Cd-MOF is a three-dimensional (3D) architecture crystallized in the…
Through anchoring polar polymer Triton X-100 on carbon materials, the MAC/S manifests excellent electrochemical performance as the cathode for Li–S batteries.
Salicylaldehyde-functionalized nano-objects are prepared via RAFT-mediated polymerization-induced self-assembly. Their simultaneous stabilization and fluorescence modification can be achieved by one-step reaction.
This paper describes the fabrication of TiO2 overlayers by atomic layer deposition to passivate the surface states on Ta3N5 thin film anodes for photoelectrochemical water oxidation. The removal of surface states reduces the overpotential and decreases the density of surface recombination centers, resulting in enhance…
[1-(13)C]pyruvate is the most widely used hyperpolarized metabolic magnetic resonance imaging agent. Using a custom-built 7.0 T polarizer operating at 1.0 K and trityl radical-doped [1-(13)C]pyruvic acid, unextrapolated solution-state (13)C polarization greater than 60% was measured after dissolution and rapid transfe…
A new member of the 2D carbon–nitrogen-rich family of nanomaterials was synthesized by polycondensation of triaminoguanidine hydrochloride with glyoxal. This new polymer (TAGP) and its transition metal complexes (TAGP–Ms) were found to be energetic and insensitive.
A PCE of 9.02% for a two-dimensional polymer as donor applied in solar cells was obtained without any additive treatment.
