Abstract Photoassisted steam reforming and dry (CO2) reforming of methane (SRM and DRM) at room temperature with high syngas selectivity have been achieved in the gas‐phase catalysis for the first time. The catalysts used are bimetallic rhodium–vanadium oxide cluster anions of Rh2VO1–3−. Both the oxidation of methane…
We combine experiment and theory to elucidate how small, local, structural changes can impact miscibility in polymer blends. Small-angle neutron scattering (SANS) experiments yield both the phase boundaries and the temperature dependence of the second derivative of the free energy of mixing. We demonstrate here, for t…
The development of lanthanide-doped Y3Al5O12 (Ln:YAG) garnet nanostructures is a hot topic in the field of inorganic nanophosphors due to the current interest in developing small nanoparticles for solid-state lighting (SSL), displays, lasers and scintillation applications. In this study, we report the preparation of h…
We consider a clean layered magnetic superconductor in which a continuous magnetic transition takes place inside a superconducting state. We assume that the exchange interaction between superconducting and magnetic subsystems is weak so that superconductivity is not destroyed at the magnetic transition. A representati…
Scaling commonly occurs at pipe wall during landfill leachate collection and transportation, which may give rise to pipe rupture, thus posing harm to public health and environment. To prevent scaling, this study prepared a low surface energy nanocomposite by incorporating silicone-acrylate polymer and hydrophobically…
We report a bulk phase-encoded surface-enhanced Raman scattering (SERS) tag, which uses a thin pinhole-free bulk phase of a Raman-active polymer other than submonolayer molecules as the signal reporter. With a pinhole-free, highly cross-linked structure, the outer bulk phase shell not only offers ideal protection to t…
Abstract The electrochemical synthesis of mesoporous ruthenium (Ru) films using sacrificial self‐assembled block polymer micelles templates, and its electrochemical surface oxidation to RuOx is described. Unlike standard methods such as thermal oxidation, the electrochemical oxidation method described here retains the…
Abstract Small particle diameter thermally expandable microspheres (TEMs) were obtained for potential utilization in wood, with special attention on their particle diameters and expansion properties. The revolving speed of homogenization (RS) of 800 ~ 3000 r min−1was applied in suspension polymerization under atmosphe…
Abstract The composition dependencies of crystal structure, and electrical and electromechanical properties were systematically investigated for epitaxial films of (1− x )(Bi 0.5 Na 0.5 )TiO 3 – x (Bi 0.5 K 0.5 )TiO 3 [(1− x )BNT– x BKT ( x = 0 –1)] deposited on (100) c SrRuO 3 //(100)SrTiO 3 substrates by a hydrother…
A rapid green synthesis of silver nanoparticles (AgNPs) using plant extract Solenostemo monastachyus (S. monastachyus) with silver nitrate is reported here. The formation of AgNPs was confirmed by a colour change in the plant extract from pale yellow to reddish brown and was further characterized by UV-Vis spectrophot…
Layered hydroxide sulfate (Ln2(OH)4SO4·2H2O) was employed as a new template for (La0.97Yb0.02RE0.01)F3 nanocrystal synthesis via fluorination (RE=Ho, Er), with the course of phase/morphology evolution being studied in detail via systematically varying the reaction temperature (up to 180 °C) and reaction duration (up t…
Glioma is the most aggressive type of brain tumors encountered in medical practice. The high frequency of diagnosed cases and risk of metastasis, the low efficiency of traditional therapy, and the usually unfavorable prognosis for patients dictate the need to develop alternative or combined approaches for an early dia…
Clinically diagnosing low-grade gliomas and microscopic metastatic tumors in the spinal cord using magnetic resonance imaging (MRI) is challenging, as the blood-brain barrier (BBB) almost completely excludes the MRI contrast agent gadopentetate dimeglumine, GdDTPA (Magnevist), from the brain. The development of a more…
A nanoplatform concept was developed to synthesize accessible photoactive magnetic nanoparticles (MNPs) of Fe 3 O 4 coated with silica. This approach was based on the covalent binding of 5,10,15,20-tetrakis(pentafluorophenyl)porphyrin (TPPF 20 ) to aminopropyl-grafted MNPs by nucleophilic aromatic substitution reactio…
Abstract Spin ice is an exotic type of magnetism displayed by bulk rare‐earth pyrochlore oxides. We discovered a spin ice‐like magnetic relaxation of [{Mn(saltmen)} 4 {Mn(CN) 6 }](ClO 4 )⋅13 H 2 O (saltmen 2− =N,N′‐(1,1,2,2‐tetramethylethylene)bis(salicylideneiminate)). This magnetic system can be considered as a two‐…
In scientific work is presented the solution of scientific and practical task – the development and evaluation of the possibility of using difficult combustible epoxyurethane (EU) mastic with increased vibration-damping properties and the necessary physical and mechanical properties for cladding the internal metal sur…
Abstract In this study, amine‐modified starch (AMS) nanoparticles are prepared from native sago starch (Metroxylon sagu) through a facile, economical, and aqueous‐based approach. Dialdehyde starch is initially synthesized by reacting sago starch with sodium periodate and followed by the addition of ethylenediamine for…
Abstract Semiconductor nanomaterials with efficient polarized‐light control in the blue region of the visible spectrum are promising candidates for modern and future photo‐information technology, display devices, and optical sensing applications. New‐type semiconductor Eu(OCN)2 nanocrystals with circularly polarized a…
A new penta‐EuIII sandwiched Dawson‐type selenotungstate (ST) [H2N(CH3)2]10H3{SeO4Eu5(H2O)8[Se2W14O52]2}·40H2O (1) was constructed by an in‐situ self‐assembly strategy. The unique architectural feature of 1 is that two [Se2W14O52]12– segments graft each other by five Eu3+ ions via oxygen linkers. Meanwhile, a disorder…
Abstract Covalently attached liquids provide a liquid–liquid surface interaction for contacting contaminants, typically achieved through use of a polydimethylsiloxane linear polymer bound to the surface at one end. The attached dimethylsiloxane polymer chain retains liquid‐like mobility through bending and rotational…
