MoS 2 decoration by Mo-atoms and the MoS 2 –Mo–graphene heterostructure: a theoretical study
Here we propose a completely new covalent heterostructure based on graphene and self-decorated MoS2 monolayers. Detailed investigation of the decoration process of the MoS2 surface by Mo adatoms was performed using first principles DFT methods. Comparison between valence-only and semicore pseudopotentials was performe…
Thermally flexible epoxy/cellulose blends mediated by an ionic liquid
Blends between the widely used thermoset resin, epoxy, and the most abundant organic material, natural cellulose are demonstrated for the first time.
The role of substrate purity and its crystallographic orientation in the defect density of chemical vapor deposition grown monolayer graphene
Here, we are reporting about the role of the copper substrate purity and its crystallographic orientation in the quality of the graphene grown using a low pressure chemical vapor deposition technique.
Extensional viscosity of copper nanowire suspensions in an aqueous polymer solution
Suspensions of copper nanowires are emerging as new electronic inks for next-generation flexible electronics. Using a novel surface acoustic wave driven extensional flow technique we are able to perform currently lacking analysis of these suspensions and their complex buffer. We observe extensional viscosities from 3…
A catalyst-free amorphous silicon-based tandem thin film photocathode with high photovoltage for solar water splitting
A catalyst-free and stable p-type a-SiC:H protected a-Si/a-SiGe tandem photocathode with high photovoltage is demonstrated for efficient solar water splitting.
Characterization and properties of organo-montmorillonite modified lignocellulosic fibers and their interaction mechanisms
In this study, cellulose fiber/flour (CF) and lignin flour (LF) separated from poplar wood flour (WF) as well as xylan as a representative of hemicellulose flour (HF), were modified with organo-montmorillonite (OMMT) through a two-step method.
Hydrothermal stability investigation of micro- and mesoporous silica containing long-range ordered cobalt oxide clusters by XAS
This work investigates the hydrothermal stability of cobalt doped silica materials with different Co/Si molar ratios (0, 0.05, 0.10, and 0.25). The resultant materials were characterized by N2 sorption and chemical structures by Raman and X-ray absorption spectroscopy before and after a harsh hydrothermal exposure (55…
Diindenothienoacene–tetrathiafulvalene redox systems
The redox properties and cation associations of extended tetrathiafulvalenes with diindenothienoacene cores are strongly dependent on the number and regioisomeric structural orientation of the central thiophene units.
Direct electrochemistry and bioelectrocatalysis of horseradish peroxidase entrapped in a self-supporting nanoporous gold electrode: a new strategy to improve the orientation of immobilized enzymes
In an air/water-stable IL, a self-supporting NPGE was first prepared for improving the orientation and biosensing ability of immobilized HRP.
Ultra-sensitive tandem colloidal quantum-dot photodetectors
The solution-processed PbSe colloidal quantum-dot (CQD) infrared photodetector with tandem architecture is proposed to address the high dark current issue. The electrical transport mechanism in tandem has been fundamentally changed in which the recombination of carriers at an intermediate layer becomes dominant rather…
A family of [Mn III 6 Ln III 2 ] rod-like clusters
Employment of H3L (= 2-(β-naphthalideneamino)-2-hydroxymethyl-1-propanol) in mixed-metal manganese-lanthanide cluster chemistry has led to the isolation of five new octametallic heteronuclear isostructural [Mn(III)6Ln(III)2] complexes. More specifically, the reaction of Mn(ClO4)2·6H2O with H3L and the corresponding la…
An impurity intermediate band due to Pb doping induced promising thermoelectric performance of Ca 5 In 2 Sb 6
Band engineering is one of the effective approaches for designing ideal thermoelectric materials. Introducing an intermediate band in the band gap of semiconducting thermoelectric compounds may largely increase the carrier concentration and improve the electrical conductivity of these compounds. We test this hypothesi…
Dipolar capillary interactions between tilted ellipsoidal particles adsorbed at fluid–fluid interfaces
Capillary interactions have emerged as a tool for the directed assembly of particles adsorbed at fluid-fluid interfaces, and play a role in controlling the mechanical properties of emulsions and foams. In this paper, following Davies et al. [Adv. Mater., 2014, 26, 6715] investigation into the assembly of ellipsoidal p…
Li 7 (BH) 5 + : a new thermodynamically favored star-shaped molecule
The potential energy surfaces (PESs) of Lin(BH)5(n-6) systems (where n = 5, 6, and 7) were explored using the gradient embedded genetic algorithm (GEGA) program, in order to find their global minima conformations. This search predicts that the lowest-energy isomers of Li6(BH)5 and Li7(BH)5(+) contain a (BH)5(6-) penta…

Doping Graphene by Chemical Treatments Using Acid and Basic Substances
We prepared single-layer graphene films through mechanical exfoliation of Kish graphite and chemical vapor deposition techniques. These samples were treated in nitric acid, sulfuric acid, sodium hydroxide and ammonium hydroxide solutions to induce doping. We used Micro Raman Spectroscopy before and after the chemical…
Microstructure and Mechanical Properties of Large-Scale Ingots of the Zr-1Mo Alloy
