Theoretical Study of the CO2 Hydrogenation into Formic Acid on Lewis Acidic Zeolites
Conversion of carbon dioxide (CO2) to more valuable chemicals has nowadays received the increasing attention from an environmental and industrial point of view. Herein, we computationally investigate the CO2 hydrogenation to formic acid on Lewis acidic zeolites by means of the density functional the...

Synthesis of N-arylsulfonamides via Fe-promoted reaction of sulfonyl halides with nitroarenes in an aqueous medium
A fascinating Fe-promoted protocol for the synthesis of N-arylsulfonamides has been developed. Starting from commercially available nitroarenes and sulfonyl chlorides, moderate to excellent yields of the corresponding N-arylsulfonamides can be obtained. In particular, Fe dust serves as the sole redu...

Cytotoxicity studies of selected cadmium-based quantum dots on 2D vs. 3D cell cultures
In our work, the cytotoxicity of selected, cadmium-based quantum dots with various surface architectures was studied on 3D spheroids. A specially designed microsystem as a tool for three-dimensional cell culture and nanoparticle toxicity evaluation was used for this aim. Two types of hydrophilic qua...

Fast, low-cost preparation of hackmanite minerals with reversible photochromic behavior using a microwave-assisted structure-conversion method
A microwave-assisted structure-conversion (MASC) method was used to obtain photochromic hackmanites (M,Na)8Al6Si6O24(Cl,S)2 (M: Li, Na, and K) in a fast (12 to 20 min) one-step process. Structural conversion from Zeolite A to hackmanite minerals has been proven to be very effective through an alumin...

Incorporation of Sb5+ into CeO2: Local Structural Distortion of the Fluorite Structure From a Pentavalent Substituent
Hydrothermal crystallisation of CeO2 from aqueous sodium hydroxide solution at 240 ○C using CeCl3·7H2O in the presence of hydrogen peroxide with addition of either SbCl3 or SbCl5 yields polycrystalline samples of antimony-containing ceria directly from solution. Powder X-ray diffraction shows a cont...

One-pot synthesis of highly fluorescent Fe2+-doped carbon dots for dual-emissive nanohybrid to detection of zinc ions and histidine
Metal ions-doping is paid a little attention comparing with the nonmetallic-element doping to improve the fluorescence intensity of carbon dots (CDs). Herein, Fe2+-doped CDs was facilely synthesized at 80 °C instead of hydrothermal method for the first time. Fe2+ was confirmed to be the only definit...

Ab initio identification of the Li-rich phase in LiFePO4
A recent discovery of anionic redox activity in Li-rich layered compounds opens a new direction for the design of high-capacity cathode materials for lithium-ion batteries. Here using extensive ab initio calculations, the thermodynamic existence of the Li-rich phase in LiFePO4 to form Li1+xFe1-xPO4 ...

Facile in situ fabrication of oriented titania submicrorods embedded into a superelastic nickel-titanium alloy fiber substrate and their application in solid-phase microextraction
A nickel-titanium oxide (NiO/TiO2) coating was in situ grown on a nickel-titanium alloy (NiTi) fiber substrate by anodic oxidation. After annealing, a uniform and dense Ni-free coating of rutile phase TiO2 submicrorods (TiO2SRs) was formed. In particular, TiO2SRs were embedded into the NiTi fiber su...

On the gas-phase formation of the HCO? anion: Ac- curate quantum study of the H?+CO radiative associ- ation and HCO radiative electron attachment
The hydrogen anion has never been observed in the interstellar medium, but it is most likely present in some interstellar regions. Since a direct detection appears especially difficult, im- proving the knowledge of the astrochemical processes involving this anion should be valuable in defining a way...

Unveiling the complex vibronic structure of canonical adenine cation
Adenine, a DNA base, exists under several tautomers and isomers that are closely lying in energy and that may form a mixture upon vaporization of solid adenine. Indeed, it is challenging to bring adenine in the gas phase, especially as a unique tautomer. The experimental conditions were tuned to pre...

Controlled morphology of ZnSe nanostructures by varying Zn/Se molar ratio: The effects of different morphologies on optical properties and photocatalytic performance
The effects of Zn/Se molar ratios on the morphology and photocatalytic performance of ZnSe nanostructures, which were synthesized by a co-precipitation method, were investigated. To intensively investigate the effects of the Zn/Se ratios, we performed a series of controllable experiments with differ...

A benzimidazole-based highly selective colorimetric and far-red fluorometric pH sensor for intracellular imaging
A turn-on fluorescent probe (E)-4-(2-(1H-benzo[d]imidazol-2-yl)vinyl)-N,N-diphenylaniline (BVD) was facilely synthesized via the ethylene bridging of triphenylamine and benzimidazole. The probe exhibited strong emission enhancement in the vis-NIR fluorescence region at 605 nm with pKa 4.14 and linea...

Fabrication of novel few-layer WS2/Bi2MoO6 plate-on-plate heterojunction structure with enhanced visible-light photocatalytic activity
In this study, a novel few-layer WS2/Bi2MoO6 heterojunction with greatly enhanced visible light photocatalytic performance was synthesized via a facile hydrothermal method. The results indicated that Bi2MoO6 nanosheets were directly grown on the surface of few-layer WS2 and form the plate-on-plate h...

Highly responsive hydrazine sensors based on donor-acceptor perylene diimides: impact of electron-donating groups
Three high-performance hydrazine sensing devices have been developed based on donor-acceptor perylenediimides (PDIs) with strongly electron-donating piperidinyl (PDI-PY), pyrrolidinyl (PDI-PI) and n-hexylamino (PDI-HE) as substituents at perylene core. These PDIs devices, compared with reported PDIs...

Sustainable approach to recycling of multilayer flexible packaging using switchable hydrophilicity solvents
Multilayer Flexible Packaging Waste (MFPW) represents the largest fraction of packaging waste and is composed mainly from multiple plastic films (80 wt. %) laminated with Al foil (5 wt.%). Mechanical and chemical recycling technologies are usually used in EU to separate polymeric fraction from Al, h...
