Control of Drug Release through the In Situ Assembly of Stimuli‐Responsive Ordered Mesoporous Silica with Magnetic Particles
ChemPhysChem - Tập 8 Số 17 - Trang 2478-2483 - 2007
Shenmin Zhu, Zhengyang Zhou, Di Zhang
AbstractA site‐selective controlled delivery system for controlled drug release is fabricated through the in situ assembly of stimuli‐responsive ordered SBA‐15 and magnetic particles. This approach is based on the formation of ordered mesoporous silica with magnetic particles formed from Fe(CO)5 via the surfactant‐template sol‐gel method and co...... hiện toàn bộ
Combined Theoretical and Experimental Investigation of CO Adsorption on Coordinatively Unsaturated Sites in CuBTC MOF
ChemPhysChem - Tập 13 Số 2 - Trang 488-495 - 2012
Miroslav Rubeš, Lukáš Grajciar, Ota Bludský, Andrew D. Wiersum, Philip L. Llewellyn, Petr Nachtigall
AbstractThe adsorption of CO in metal–organic framework CuBTC material is investigated by a combination of theoretical and experimental approaches. The adsorption enthalpy of CO on CuBTC determined experimentally to be −29 kJ mol−1 at the zero‐coverage limit is in very good agreement with the adsorption enthalpy calculated at the combined DFT–a...... hiện toàn bộ
Facile Template‐Free Synthesis of Bi2O2CO3 Hierarchical Microflowers and Their Associated Photocatalytic Activity
ChemPhysChem - Tập 11 Số 10 - Trang 2167-2173 - 2010
Hefeng Cheng, Baibiao Huang, Kesong Yang, Zeyan Wang, Xiaoyan Qin, Qian Zhang, Ying Dai
AbstractHierarchical Bi2O2CO3 flowerlike microstructures have been synthesized for the first time using a facile, template‐free, and low‐temperature solution method. With an average diameter of about 3 μm, the as‐prepared Bi2O2CO3... hiện toàn bộ
Spectroelectrochemical Studies on Quinacridone by Using Poly(vinyl alcohol) Coating as Protection Layer
ChemPhysChem - Tập 16 Số 10 - Trang 2206-2210 - 2015
Sandra Enengl, Christina Enengl, Philipp Stadler, Helmut Neugebauer, Niyazi Serdar Sariçiftçi
AbstractSpectroscopic measurements in the infrared range combined with electrochemistry are a powerful technique for investigation of organic semiconductors to track changes during oxidation and reduction (p‐ and n‐doping) processes. For these measurements it is important that the studied material, mostly deposited as a thin film on an internal reflection element, ...... hiện toàn bộ
Non‐Haloaluminate Room‐Temperature Ionic Liquids in Electrochemistry—A Review
ChemPhysChem - Tập 5 Số 8 - Trang 1106-1120 - 2004
Marisa C. Buzzeo, Russell G. Evans, Richard G. Compton
AbstractSome twenty‐five years after they first came to prominence as alternative electrochemical solvents, room temperature ionic liquids (RTILs) are currently being employed across an increasingly wide range of chemical fields. This review examines the current state of ionic liquid‐based electrochemistry, with particular focus on the work of the last...... hiện toàn bộ
Probing the Reorganization of Ionic Liquids’ Structure Induced by CO2 Sorption
ChemPhysChem - Tập 21 Số 12 - Trang 1230-1234 - 2020
Luiz Fernando Lepre, Margarida F Costa Gomes, Rômulo A. Ando
AbstractThe sorption of CO2 is often used to modify the macroscopic properties of liquids and solids. In the particular case of ionic liquids, different from molecular liquids, the sorption of CO2 may not induce volume expansions due to the strong Coulombic interactions between the ions of the fluid. However, a considerable...... hiện toàn bộ
D- orL-Alanine: That Is the Question
ChemPhysChem - Tập 1 Số 1 - Trang 60-62 - 2000
Jon K. Laerdahl, Ralf Wesendrup, Peter Schwerdtfeger
A Spray‐Based Technique for the Production of MnS Thin Films
ChemPhysChem - Tập 16 Số 2 - Trang 353-359 - 2015
Lilac Amirav, Efrat Lifshitz
AbstractA spray‐based technique, originally developed for the production of semiconductor nanocrystals, is utilized for the preparation of high‐quality nanocrystalline thin films, as demonstrated with manganese sulfide. The films are formed by the use of pneumatic‐assisted thermospray or pneumatic nebulizers. Our simple, low‐cost, and low‐temperature process result...... hiện toàn bộ
Optical Resonator Biosensors: Molecular Diagnostic and Nanoparticle Detection on an Integrated Platform
ChemPhysChem - Tập 13 Số 2 - Trang 427-436 - 2012
Martin D. Baaske, Frank Vollmer
AbstractOptical resonator biosensors are emerging as one of the most sensitive microsystem biodetection technology that does not require amplification or labeling of the analyte. This minireview provides a scholarly introduction to this research area and reviews current advances in molecular diagnostics and nanoparticle detection.
Absorption Spectroscopy Analysis of Calcium–Phosphate Glasses Highly Doped with Monovalent Copper
ChemPhysChem - Tập 17 Số 11 - Trang 1642-1646 - 2016
José A. Jiménez
AbstractCaO–P2O5 glasses with high concentrations of monovalent copper ions were prepared by a simple melt–quench method through CuO and SnO co‐doping. Spectroscopic characterization was carried out by optical absorption with the aim of analyzing the effects of Cu+ ions on the optical band‐gap energies,...... hiện toàn bộ
