The effect of hydrogen sulfide ions (HS − ) on the passivity of type 316L stainless steel was investigated in pH 8.4 boric acid-borate buffer solution. Galvanostatic polarization of a silver microelectrode covered with Ag 2 S generated both OH − and HS − above the stainless steel surface. During potentiostatic polariz…
Discovery and Understanding of the Ambient-Condition Degradation of Doped Barium Cerate Proton-Conducting Perovskite Oxide in Solid Oxide Fuel Cells, Yan, Ning, Zeng, Yimin, Shalchi, Babak, Wang, Wei, Gao, Tong, Rothenberg, Gadi, Luo, Jing-li
A gram-scale approach has been developed to prepare highly pure graphene quantum dots (GQDs) from Vulcan XC-72 carbon black refluxed with concentrated nitric acid using a home-built experimental system.
In this work, (1 - x)(K0.48Na0.52)(Nb(0.95-y-z)Ta(z)Sb(y))O3-xBi0.5(Na0.82K0.18)0.5ZrO3, {abbreviation: KNNST-BNKZ-x-y-z} lead-free piezoceramics were prepared by a conventional solid-state reaction method, and the composition dependence of their phase structures and electrical properties was systematically discussed.…
Proton–dopant interactions in the exciting new SOFC electrolyte material, Y and Sn co-doped BaZrO 3 , are shown to be potentially detrimental to its electrochemical performance.
This paper presents a study of adsorption and vibrational features of folic acid, using surface-enhanced Raman scattering (SERS). A gold-capped silicon nanopillar (Au NP) with a height of 600 nm and a width of 120 nm was utilized to study the vibrational features of FA molecules adsorbed on the nanopillars within the…
Solid lines denote the main pathways of CH 4 formation by syngas obtained in this work. E a denotes the activation barrier for the corresponding step. Δ H represents the relevant reaction energy (unit: eV).
Here, we report the synthesis of silicone nanoparticles by a facile means of hydrolysing trichloromethylsilane in toluene under ambient conditions in the absence of a catalyst, and their application in the fabrication of superhydrophobic surfaces.
Hollow CuFe 2 O 4 nanospheres show high catalytic activity on the thermal decomposition of RDX and FOX-7.
Thrombosis and neointimal hyperplasia are the main causes for the failure of small diameter vascular grafts, and a complete and functional endothelium is essential in preventing these problems. Therefore, grafts that could be endothelialized rapidly are highly desirable. This study constructed a vascular graft with ca…
Novel Au@Ag core-shell nanocubes (NCs) were successfully prepared by the controlled epitaxial growth of Ag shells onto Au nanoellipsoids (NEs) in the presence of surfactants. The growth mechanism of the Au@Ag core-shell NCs was systematically investigated by analyzing their morphology, optical properties, and crystall…
This study was conducted to evaluate the potential of peanut meal (PM) to produce plywood adhesives via sodium dodecyl sulfate (SDS) and ethylene glycol diglycidyl ether (EGDE) modification.
A chiral spin crossover complex was obtained in the form of nanoparticles and gels that undergo a cooperative spin state switch around room temperature.
Schottky contacts, formed at metal/semiconductor interfaces, always have a large impact on the performance of field-effect transistors (FETs). Here, we report the experimental studies of Schottky contacts in two-dimensional (2D) transition metal dichalcogenide (TMDC) FET devices. We use scanning photocurrent microscop…
The control of the charge distribution in a monolayer of switchable cobalt-dioxolene complexes undergoing Valence Tautomerism (VT) has been achieved by means of thermal and optical stimuli. Thiol-derivatised VT molecules have been grafted on polycrystalline gold surface as monolayers from solution. X-ray photoelectron…
The first examples of homo- and hetero-polymetallic organophosphates of gadolinium are reported. Magnetic measurements reveal a higher magnetic entropy change for the isotropic {Gd(III)5} complex (25.8 J kg(-1) K(-1)) as compared to the heterometallic {Gd(III)4Co(II)} complex (20.3 J kg(-1) K(-1)), which is attributab…
The proliferation of nano-enabled products (NEPs) renders human exposure to engineered nanomaterials (ENMs) inevitable. Over the last decade, the risk assessment paradigm for nanomaterials focused primarily on potential adverse effect of pristine, as-prepared ENMs. However, the physicochemical properties of ENMs may b…
A roller electrospinning system was used to produce nanofibres by using different solution systems. Although the process of electrospinning has been known for over half a century, knowledge about spinning behaviour is still lacking. In this work, we investigated the effects of salt for two solution systems on spinning…
Water interactions of ultra-thin films of wood-derived polysaccharides were investigated by using surface sensitive methods, Quartz Crystal Microbalance with Dissipation (QCM-D) and Atomic Force Microscopy (AFM). These approaches allow systematic molecular level detection and reveal information on the inherent behavio…
The optical properties of multi-component metal nanostructures (or nanoalloys) are the subject of an intense and rapidly growing experimental and theoretical activity. In this perspective article, we first provide a survey of the most recent developments in the field, concerning both theoretical methods, especially at…
