Polystyrenes with hydrophobic end groups are synthesized from a series of alkyl or fluorinated ATRP initiators to fine-tune the surface morphologies of honeycomb films prepared by the breath figure method.
Due to the synergistic contributions of graphene and ionic liquid, the as-prepared RGO–Bi 2 WO 6 samples exhibited the remarkably enhanced photocatalytic activities under visible light irradiation.
Eu- and Li-doped yttrium oxide nanocrystals [Y2-xO3; Eux, Liy], in which Eu and Li dopant ion concentrations were systematically varied, were developed and characterized (TEM, XRD, Raman spectroscopic, UV-excited lifetime, and ICP-AES data) in order to define the most emissive compositions under specific X-ray excitat…
The production of a functional cardiac tissue to be transplanted in the injured area of the infarcted myocardium represents a challenge for regenerative medicine. Most cell-based grafts are unviable because of inadequate perfusion; therefore, prevascularization might be a suitable approach for myocardial tissue engine…
Polymers with functional end groups are synthesized using a cyclic lactone ATRP initiator for honeycomb-patterned porous films by the breath figure method.
In this work, the effect of surface hydrogenation of different metal oxides, in particular molybdenum and tungsten oxides widely used to enhance hole extraction and zinc and titanium oxides widely used to enhance electron extraction, on the nanomorphology and the charge generation efficiency of polymer blend solar cel…
BACKGROUND: X-ray scattering is a well-established method for measuring cellulose microfibril angles in secondary cell walls. However, little data is available on the much thinner primary cell walls. Here, we show that microfibril orientation distributions can be determined by small angle X-ray scattering (SAXS) even…
The influence of swelling (i.e. the size of tetraalkylammonium surfactant molecule, the presence of tetrapropylammonium hydroxide (TPAOH), pH) and pillaring (i.e. the ratio between the swollen precursor IPC-1P and tetraethyl orthosilicate) conditions on the structure and textural properties of the resulting materials…
We herein report a theoretical analysis using density functional theory (DFT) and time-dependent DFT (TDDFT) to study the electronic structures and photophysical properties of mixed-ligand Cu(i) complexes. An evaluation of the non-radiative and radiative decay rate constants (knr and kr) is presented. It is found that…
Composites with the addition of alumina nanofillers show improvement in mechanical properties. The PMMA polymer was used as a matrix and two different types of nanofillers, having extremely different shapes were added in the matrix to form the composite. Reinforcements were based on alumina nanoparticles having either…
We develop a new S(DIH) equation based on the difference of isosteric heats (DIH) to calculate the selectivity for CO2 over CH4 in metal–organic frameworks (MOFs) and covalent–organic materials. Using the S(DIH) equation to predict the selectivity requires only the adsorption isotherms of pure components and the DIH o…
A luminescent [Tb 2 (BDC) 3 (H 2 O) 4 ] n film with a leaf-like morphology is fabricated on FTO by electrochemical method, the film exhibits highly selective detection of Cu 2+ .
Doping a small amount of La 3+ (3.66 mol%) into hematite nanostructures narrows the bandgap of hematite, leading to improved photoelectrochemical performance.
Three-dimension (3D) flowerlike β-In 2 S 3 microspheres have been successfully synthesized by a facile solvothermal method using thioacetamide (TAA, CH 3 CSNH 2 ) as both a sulfur source and ligand of In 3+ in the ethanol–water system.
A ternary complex among D2 , DNA and CB[7] can be formed.
A novel hybrid material of chitin–nGO was obtained. nGO reinforces the material by rearrangement of chitin chains, improving its chemical and mechanical properties.
A new tandem catalytic system mediates very efficiently and selectively at room temperature two sequential reactions to produce relevant derivatives in one pot. Remarkably, this new concept of catalysis allows the facile synthesis of polypeptides and provides direct access to cyclic carbonates in high yields, through…
The first anhydrous molecular complexes of uranium(III) chloride, soluble in polar aprotic solvents, are reported, including the structures of the dimeric [UCl3(py)4]2 and the trimetallic [UCl(py)4(μ-Cl)3U(py)2(μ-Cl)3UCl2(py)3].
A three-dimensional (3D) nanoporous coordination polymer, [Pb(4-bpdb)(μ-NO 3 )(μ-SCN)] n ·1.5CH 3 OH ( TMU-15 ), was synthesized. In this compound, we successfully loaded the porous crystals with I 2 by suspending them in a solution of I 2 in cyclohexane.
Morphologies of gold nanoparticles play an important role in determining their chemical and physical (catalytic, electronic, optical, etc.) properties. Therefore, a fundamental understanding of the morphological stability is of crucial importance to their applications. In this article, we employed atomistic simulation…
