Monolayers of semiconducting transition metal dichalcogenides hold the promise for a new paradigm in electronics by exploiting the valley degree of freedom in addition to charge and spin. For MoS2, WS2, and WSe2, valley polarization can be conveniently initialized and read out by circularly polarized light. However, t…
Thermoelectric materials enable direct conversion between thermal and electrical energy and provide a viable route for power generation and electric refrigeration. In this paper, we use first-principles based methods to predict a very high figure of merit ( ZT ) performance in hole doped GeSe crystals along the crysta…
Color centers in diamond provide a promising platform for quantum optics in the solid state, but often their desirable properties are spoiled when they are incorporated into actual devices. The authors demonstrate a simple technique to create centers with uniformly high-quality optical properties, even inside nanoscal…
Formulating room-temperature ionic liquid (RTIL) mixed electrolytes was recently proposed as an effective and convenient strategy to increase the capacitive performance of electrochemical capacitors. Here we investigate the electrical double-layer (EDL) structure and the capacitance of two RTILs, 1-ethyl-3-methylimida…
The European Union-United States Communities of Research were established in 2012 to provide a platform for scientists to develop a "shared repertoire of protocols and methods to overcome nanotechnology environmental health and safety (nanoEHS) research gaps and barriers" (www.us-eu.org/). Based on work within the Eco…
Polylactic acid (PLA) is a biodegradable polyester derived from renewable resources, which is a leading candidate for the replacement of traditional petroleum-based polymers. Since the global production of PLA is quickly growing, there is an urgent need for the development of efficient recycling technologies, which wi…
Quantum dots (QDs), nano-carriers for drugs, can help realize the targeting of drugs, and improve the bioavailability of drugs in biological fields. And, a QD nano-carrier system for drugs has the potential to realize early detection, monitoring, and localized treatments of specific disease sites. In addition, QD nano…
Understanding and exploiting the remarkable optical and electronic properties of phosphorene require mass production methods that avoid chemical degradation. Although solution-based strategies have been developed for scalable exfoliation of black phosphorus, these techniques have thus far used anhydrous organic solven…
Rhenium disulfide (ReS 2 ) is attracting more and more attention for its thickness‐depended direct band gap. As a new appearing 2D transition metal dichalcogenide, the studies on synthesis method via chemical vapor deposition (CVD) is still rare. Here a systematically study on the CVD growth of continuous bilayer ReS…
XDSAPP is an expert system and graphical user interface (GUI) for the automated processing of diffraction images using the XDS program suite and other programs. The latest major update and the extension of the program are presented here. The update includes new features, as well as improvements in the GUI and the unde…
Innovative phosphorus and nitrogen dual-doped hollow carbon dots (PNHCDs) have been fabricated for anticancer drug delivery and biological imaging. The functional groups of PNHCDs are introduced by simply mixing glucose, 1,2-ethylenediamine, and concentrated phosphoric acid. This is an automatic method without externa…
A range of numerous corrosion inhibitors, viz. organic molecules with hetero atoms and π-electron clouds, inorganic salts and plant excerpts likewise their corresponding phytoconstituents were reported with success for metals in different corrosive media. Various literature reviews related to corrosion inhibitors have…
The high-efficiency catalyst is the key factor of volatile organic compounds (VOCs) catalytic combustion. Herein, hierarchical core–shell Al 2 O 3 @Pd-CoAlO (Pd-CoAlO-Al) microspheres have been successfully prepared and used for toluene combustion. The experimental results reveal that the core–shell Pd-CoAlO-Al exhibi…
Phosphorene, a novel 2D material isolated from bulk black phosphorus (BP), is an intrinsic p-type material with a variable bandgap for a variety of applications. However, these applications are limited by the inability to isolate large films of phosphorene. Here we present an in situ chemical vapor deposition type app…
Scaling relationships are theoretical constructs that relate the binding energies of a wide variety of catalytic intermediates across a range of catalyst surfaces. Such relationships are ultimately derived from bond order conservation principles that were first introduced several decades ago. Through the growing power…
Here the intergranular and pitting corrosion resistance of super austenitic stainless steel Type UNS31254 was investigated, whose performance declined obviously after aging at 900 C for short terms. Test methods including the nitric acid immersion test and the potentiostatic pulse technique (PPT) were applied respecti…
A new series of isoxazolidine derivatives of aldehyde were synthesized using a nitrone cycloaddition reaction. The corrosion inhibition efficiency of these synthesized compounds on mild steel were determined using a gravimetric method, linear polarization resistance, Tafel extrapolation method, electrochemical impedan…
In the last two decades intensive grow of industry of building materials from renewable resources is observed. Such situation is related to some aspects: global warming, environmental pollution, impact on human health, environmental impact of materials at their end-of-life. In current study development of thermal insu…
Using a scaleable chemical method, the ultrathin MnO 2 nanosheets-decorated CuO nanoneedle arrays@Cu sheet has been synthesized and applied as electrodes, while CuO nanoneedles were obtained via an electrochemical deposition at room temperature. Such binder-free Cu/CuO@MnO 2 electrodes were measured by using X-ray dif…
AZ31B magnesium alloy was anodized in an alkaline electrolyte containing sodium borate, sodium silicate and sodium citrate. Ammonium metavanadate (NH 4 VO 3 ) was used as an additive to improve the anti-corrosion ability of anodization film. The anodization film was characterized by X-ray diffraction and scanning elec…
