AgCl semiconductor nanocrystals (NCs) with trapezohedral (TPH) and concave hexoctahedral (HOH) structures have been successfully synthesized for the first time in high yield by a direct one-pot solvothermal method. The as-prepared TPH, concave HOH AgCl NCs with unconventional polyhedral shapes and smooth surfaces were…
We report the synthesis, X-ray diffraction, thermal, magnetic, Raman and IR studies of three heterometallic MOFs, [(CH3)2NH2][Fe(III)M(II)(HCOO)6] with M = Zn (DMFeZn), Ni (DMFeNi) and Cu (DMFeCu), crystallizing in the niccolite type structure. DMFeZn and DMFeNi crystallize in the trigonal structure (space group P3[co…
Upconversion is a promising way to trigger high-energy photochemistry with low-energy photons. However, combining upconversion schemes with non-radiative energy transfer is challenging because bringing several photochemically active components in close proximity results in complex multi-component systems where quenchi…
Results of investigation of the incorporation of zirconia and silica nanoparticles into the coatings formed on magnesium alloy by plasma electrolytic oxidation are presented. Comprehensive research of electrochemical and mechanical properties of obtained coatings was carried out. It was established that the polarizati…
A dispersive Raman spectrometer was used with three different excitation sources (Argon-ion, He-Ne, and Diode lasers operating at 514.5 nm, 633 nm, and 782 nm, resp.). The system was employed to a variety of Raman active compounds. Many of the compounds exhibit very strong fluorescence while being excited with a laser…
Films made from starches are colorless, tasteless, non-toxic, biodegradable, and economical, besides having a low permeability to oxygen. Moreover, the cross-linking modification (phosphatation) could improve its physicochemical properties by reinforcing the hydrogen links inside the granules. The goals of this study…
In nature, polysaccharide glycosidic bonds are cleaved by hydrolytic enzymes for a vast array of biological functions. Recently, a new class of enzymes that utilize an oxidative mechanism to cleave glycosidic linkages was discovered; these enzymes are called lytic polysaccharide monooxygenases (LPMO). These oxidative…
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.
