We report the measurement of conductance and thermopower of C60 molecular junctions using a scanning tunneling microscope (STM). In contrast to previous measurements, we use the imaging capability of the STM to determine precisely the number of molecules in the junction and measure thermopower and conductance continuo…
Scattering-type scanning near-field optical microscopy (s-SNOM) and Fourier transform infrared nanospectroscopy (nano-FTIR) are emerging tools for nanoscale chemical material identification. Here, we push s-SNOM and nano-FTIR one important step further by enabling them to quantitatively measure local dielectric consta…
The epidermal growth factor receptor (EGFR) is a key protein in cellular signaling, and its kinase domain (EGFR kinase) is an intensely pursued target of small-molecule drugs. Although both catalytically active and inactive conformations of EGFR kinase have been resolved crystallographically, experimental characteriza…
Nanoporous polyelectrolyte membranes with hierarchical and unique pore architectures can be readily made via electrostatic complexation between imidazolium-based poly(ionic liquid)s and poly(acrylic acid) in a variety of morphologies. Coating the membrane onto the surface of an optical fiber resulted in a device with…
Metal-oxide semiconductors have attracted considerable attention as next-generation circuitry for displays and energy devices because of their unique transparency and high performance. We propose a simple, novel and inexpensive ‘aqueous route’ for the fabrication of oxide thin-film transistors (TFTs) at low annealing…
The steam reforming of ethanol on a Ni-based CeO 2 -supported catalyst was studied using in situ X-ray diffraction (XRD), operando diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS), and mass spectroscopy (MS) with a focus on the structural characterization of the catalysts, chemical identification o…
Abstract Although Java does not run on some handheld devices, e.g., iPads and iPhones, JavaScript does. The development of JSmol, a JavaScript‐only version of Jmol, is described, and its use in Proteopedia is demonstrated. A key aspect of JSmol is that it includes the full implementation of the entire set of Jmol func…
Advances in the field of boron chemistry have expanded the application of boron from material use to medicine. Boron-based drugs represent a new class of molecules that possess several biomedical applications including use as imaging agents for both optical and nuclear imaging as well as therapeutic agents with antica…
Abstract Structural complexity of minerals is characterized using information contents of their crystal structures calculated according to the modified Shannon formula. The crystal structure is considered as a message consisting of atoms classified into equivalence classes according to their distribution over crystall…
Ten days old seedlings of chickpea (Cicer arietinum L var. HC-1) were foliar sprayed with 1.5 or 10 ppm aqueous solution of zinc oxide (ZnO) nanoparticles and effects were compared with corresponding concentration of zinc sulphate and ZnO of normal size. Maximum promontory response with respect to shoot dry weight was…
Plasmonic metallic nanoparticles (NPs) have recently been identified as a breakthrough route for enhancing the efficiency of organic photovoltaic (OPV) devices. The present review highlights the different strategies of incorporating plasmonic NPs for light trapping into either the active or the buffer layer or at vari…
Organic photovoltaic (OPV) cells represent an exciting class of renewable energy technology; they are lightweight and flexible, and have a low production cost. Over the last two decades, the efficiency of these devices has improved significantly, in particular through the development of solution-processed bulk heteroj…
Single phase Ba0.8Pb0.2TiO3 (BPT) with improved dielectric and ferroelectric properties was synthesized by Mechano-Chemical Activation (MCA). It is also interesting to investigate the change in different electrical parameters of the sample synthesized by MCA. In the present work, we are reporting the Complex Impedance…
Novel low cost deposition technique for p-n junction preparation has been performed for low temperature deposition. The substrate was dipped in a precursor followed by solid state reaction at 200°C. Nano-structured films were produced as multi-layers. The technique has been employed for binary and ternary metal sulfid…
Demetallation of magnesium tetra-4-morpholinyl(piperidinyl)-5-R-substituted phthalocyanines was performed to obtain the corresponding metal-free phthalocyanines. Their electronic absorption spectra were shown to depend on the nature of the solvent. It was found that both the saturated heterocycle and the oxyaryl subst…
In this paper, electroplated Cu was used as substrate to grow graphene by chemical vapor deposition (CVD) with a mixture gas of methane, hydrogen and argon. The different electroplated Cu grain size after annealing was studied. We present the growth temperature, growth time and methane concentration are key parameters…

摘要： 采用增重法和金相显微技术，研究了不同浓度的沉降硫-石油醚溶液对银片的腐蚀作用，以及噻二唑型缓蚀剂TSJ-T6在不同浓度、不同温度下的缓蚀效率。 研究表明，TSJ-T6缓蚀剂对银片具有很好的缓蚀性能，且随着缓蚀剂浓度的增加，缓蚀效率也随之提高，当缓蚀剂浓度达到10.0 μg/g时，缓蚀效率达到94.37%。 经过吸附等温线拟合，得到缓蚀剂TSJ-T6在银片表面的缓蚀符合Langmuir吸附等温式，吸附过程为放热反应过程。
We measured NMR, Raman spectra and AC impedance for BaO-ZnO-P2O5 glasses. The short-range order of these glasses was based on metaphosphate (Q P 2) structure. A part of O-P-O bonding was broken and the mobile proton concentration increased for ternary BaO-ZnO-P2O5 glasses. The protonic conductivity was 2 × 10-7 S/cm f…
The reduction in the operating temperature of solid oxide fuel cells (SOFC) to 800°C or lower allows for the use of metallic alloys as the interconnect material. The most commonly used alloys are ferritic stainless steels, which have a combination of good oxidation resistance and appropriate coefficient of thermal exp…
