In this study, rhodium and antimony doped nanorod (RS-TONR) was prepared by a molten salt solid state chemical reaction, and TiO2 nanorod and titanate nanotube (RS-TONR/TiNT) composite photocatalyst was synthesized by a hydrothermal method for different reaction times. The structural and chemica...

Copper-based titanate intercalation electrode materials (referred as Cu–TO) were achieved by electrochemical reduction of the intercalated cupric ions that were ion exchanged on the layer structured titanate films by using n-propylamine as an exfoliating agent. The copper-based titanate interca...

Combined water pollution with the coexistence of heavy metals and organic contaminants is of great concern for practical wastewater treatment. In this study, a jaboticaba-like nanocomposite, titanate nanotubes supported TiO2 (TiO2/TiNTs), was synthesized by a two-step hydrothermal treatment. TiO...

For the first time, photosensitization of selected alkaline titanates with surface charge transfer complexes has been proven. Activation of BaTiO3, SrTiO3 and CaTiO3 to visible as well as ultraviolet light has been achieved by impregnation with catechol, salicylic acid and 2,3-naphthalenediol. S...

Titania and titanate nanotubes were evaluated as adsorbents for the removal of Hg(II) from aqueous solution. Commercial titanium dioxide (TiO2-P25, Evonik), a synthesized anatase sample obtained by the sol-gel method (TiO2-SG) and titanate nanotubes (TNT) prepared via hydrothermal treatment were...

With different functional groups and hydrophobic/hydrophilic properties, natural organic matters (NOMs) displayed different combining capacities with metal ions. By using XAD-4 and DAX-8 resins, NOMs in natural lake were isolated into three fractions, i.e., HoB (hydrophobic base), HoA (hydrophob...

Impregnation with alkali metals is a convenient and attractive way to enhance the CO2 sorption uptake of hydrotalcite. In this study, NaNO3 was used as a novel alkali metal precursor to increase the basicity of commercial hydrotalcite. Also, the influence of NaNO3 on the structural and textural ...

A series of hydrotalcites (HTCs) samples with different compensating anions was prepared (several anions never used before). The physicochemical characterization of these materials was realized through several techniques (including XRD and SEM/EDS). The CO2 sorption capacities of the HTCs were a...

CO2 hydrogenation, in which CO2 conversion to methanol plays a key role, is of increasing importance in mitigating the climate crisis. However, high reaction pressures are required to conduct methanol synthesis because of poor catalytic performance of conventional catalysts, leading to high ener...

CuAl hydrotalcite-SBA-15 composite materials are prepared by precipitation-deposition method. The CO2 adsorption and regeneration process are carried out in a fixed bed reactor. This composite has thermal stability derived from hydrotalcite and moderate regeneration temperature from the porous m...

The structure of the very reactive, yet fairly long-lived, FClO molecule has been determined experimentally for the first time. Analysis of the high-resolution infrared spectrum of its ν1 band provided the spectroscopic constants needed. FClO was obtained as the main product of the reaction bet...

The standard enthalpies of formation of some samarium alloys in the binary systems SmX (where X = C, Si, Ge, Sn) have been determined by direct synthesis calorimetry at 1273±2 K. The following values of ΔH°1 (kJ mol−1 of atoms) are reported; SmC2 = −25.7 ± 1.1; SmSi = −79.7 ± 2.9; SmSi2 =...

Using analytical transmission electron microscopy techniques, nanocrystals embedded in 4H–SiC are studied which formed after high dose samarium (Sm), cobalt (Co), and Sm-and-Co-ion implantations and annealing. SmSi2, Sm5C2, Co2Si and SmCo-rich nanocrystals have been identified in terms of their...

Hemostatic macroporous polymer foams synthesized via high internal phase emulsion (HIPE) templating were loaded with iodine to impart broad-spectrum antimicrobial activity. The effects of kaolin loading and iodine content on structure and antimicrobial activity were identified. ATR-FTIR, Raman, ...

In this work, a kind of slow-release and water-retention fertilizer was fabricated by free radical copolymerization of potato starch, acrylic acid, acrylamide, and β-cyclodextrin modified by maleic anhydride, accompanying halloysite nanotubes whose cavities were enlarged by acidification and lo...

Optical characterization and simulations have been applied to study formamidinium + cesium lead triiodide (FA1-xCsxPbI3) perovskite based thin films and solar cells. Near infrared to ultraviolet complex dielectric function (ε = ε1 + iε2) spectra of varying cesium-to-formamidinium ratios in so...

Halodeboronation of organotrifluoroborates using commercially available tetrabutylammonium tribromide (TBATB) or cesium triiodide in aqueous medium is reported. The mild, transition metal-free method has proven to be tolerant of a wide range of functional groups. High regio- and chemoselectivity...

Hybridization of Caesium and Formamidinium is considered as a promising approach to fabricate methylammonium-free perovskites for photovoltaic applications. Typically, CsxFA1-xPbI3 perovskite solar cells employ the normal device structure, which incorporates a high temperature processed rigid me...

New anti-cancer therapy with boron neutron capture therapy (BNCT) is based on the nuclear reaction of boron-10 with neutron irradiation. The median survival of BNCT patients with glioblastoma was almost twice as long as those receiving standard therapy in a Japanese BNCT clinical trial. In this ...

The successful treatment of cancer by boron neutron-capture therapy (BNCT) requires the selective delivery of relatively high concentration of 10B compounds to malignant tumor tissue. This study focuses on a new tumor-targeting drug delivery system for BNCT that uses small (less than 200 nm in d...
