Most recently, manganese oxides nanomaterials, including MnO and MnO2, have attracted great interest as anode materials in lithium‐ion batteries (LIBs) for their high theoretical capacity, environmental benignity, low cost, and special properties. Up to now, manganese oxides nanostructures with excellent properties an…
An understanding of nanocrystal growth mechanisms is of significant importance for the design of novel materials. The development of liquid cells for transmission electron microscopy (TEM) has enabled direct observation of nanoparticle growth in a liquid phase. By tracking single particle growth trajectories with high…
A real-time colorimetric and ratiometric fluorescent probe based on modulating the intramolecular charge transfer (ICT) of the coumarin platform for selective detection of sulfite is presented. This reaction based probe utilized the Michael addition to the dicyano-vinyl group with the detection limit of 5.8 × 10(-5) M…
The possibility of producing chemical fuel (hydrogen) from the solar-thermal energy input using an isothermal cycling strategy is explored. The canonical thermochemical reactive oxide, ceria, is reduced under high temperature and inert sweep gas, and in the second step oxidized by H2O at the same temperature. The proc…
Belt-persistent tubular cycloarylenes possessing extended sp2-networks of finite single-wall carbon nanotubes (SWNT) have been synthesised from an abundantly available pigment possessing the dibenzo[def,mno]chrysene (anthanthrene) framework. The introduction of bulky substituents allowed for the diastereoselective pro…
The reaction conditions for the synthesis of Cu-BTC (BTC = benzene-1,3,5-tricarboxylic acid) were elucidated using a continuous-flow microreactor-assisted solvothermal system to achieve crystal size and phase control. A high-rate synthesis of Cu-BTC metal-organic frameworks with a BET surface area of more than 1600 m(…
We report microwave assisted bottom-up fabrication of flat two-dimensional carbon nitride from formamide (HCONH2). Microwave irradiation of HCONH2 produces carbon nitride dots (CNDs) which are used as precursors for synthesis of carbon nitride (C3N4). The two-dimensional (2D) carbon nitride sheets are formed by evapor…
In the quest to improve the performance of polymer solar cells (PSCs) with a view to realizing economic viability, various solvent additives such as 1,8-octanedithiol (ODT), 1,8-diiodooctane (DIO), diphenylether (DPE) and 1-chloronaphthalene (CN) are used in easily obtainable poly(2,3-bis-(3-octyloxyphenyl)quinoxaline…
We show that the MOF NU-111 exhibits equally high volumetric and gravimetric methane uptake values, both within ≈75% of the DOE targets at 300 K. Upon reducing the temperature to 270 K, the uptake increases to 0.5 g g(-1) and 284 cc(STP) per cc at 65 bar. Adsorption of CO2 and H2 is also reported. Simulated isotherms…
Polymeric organic photovoltaic (OPV) cells are promising candidates for low-cost, high-performance energy sources due to their low material and processing costs, flexibility, and ease of manufacturing by solution processes. However, low power-conversion efficiency (PCE) has impeded the development of OPV cells. The lo…
Worldwide, plant protein contributes substantially as a food resource because it contains essential amino acids for meeting human physiological requirements. However, many versatile plant proteins are used as medicinal agents as they are produced by using molecular tools of biotechnology. Proteins can be obtained from…
Film processing and patterning techniques are a prerequisite to fully exploit the potential of metal–organic frameworks (MOFs) in integrated applications. We report a solvent-free approach for the synthesis of ZIF-8 thin films and patterns through the reaction of ZnO films with melted 2-methylimidazole.
Coarse grained molecular dynamics simulations are conducted to study the interaction of graphene nanosheets with a lipid bilayer, focusing on the effects of graphene thicknesses (single/multi-layered graphene), oxidation and surface absorption by lipid molecules. The results show that a hydrophobic corner of graphene…
Graphene-loaded sodium alginate (NaAlg) nanocomposite membranes have been prepared to enhance the pervaporation (PV) dehydration of isopropanol. The effect of graphene loading on the physico-chemical properties, micro-morphology and barrier performance of the derived nanocomposite membranes was investigated as a funct…
A new bifunctional tetrazolate-5-carboxylate ligand has been prepared and employed in assembling 2-D Eu(III)–Zn(II) and Tb(III)–Zn(II) isostructural heterometallic MOFs with a (3,6)-connected kgd topology. The ligand in Tb3+ MOFs not only shows an antenna effect to transfer absorbed energy to Tb3+ centers to emit char…
We report a unique approach of using a water soluble polymer (a cellulose derivative) to generate organogels via a facile, low temperature process. This finding is an important step towards the development of liquid oil-based soft matter systems for applications in non-bio and bio-related fields.
The excited-state dynamics, luminescence, and redox properties of a series of hexanuclear molybdenum cluster complexes, (nBu4N)2[Mo6X14] and (nBu4N)2[Mo6X8(CF3COO)6] (X = Cl, Br, or I), were investigated. Substitution of the apical halogen ligands for the trifluoroacetate ligands increased the oxidation potentials and…
Optimization of the physical and electronic properties of organic semiconductors is a key step in improving the performance of organic light emitting diodes, organic photovoltaics, organic field effect transistors, and other electronic devices. Separate tuning of the physical and electronic properties of these organic…
Microbial fuel cells (MFC) are a promising system to simultaneously accomplish the goal of energy production and wastewater treatment.
