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
A Spray‐Based Technique for the Production of MnS Thin FilmsChemPhysChem - 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 PlatformChemPhysChem - 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.
Biosilica‐Entrapped Enzymes Studied by Using Dynamic Nuclear‐Polarization‐Enhanced High‐Field NMR SpectroscopyChemPhysChem - Tập 16 Số 13 - Trang 2751-2754 - 2015

AbstractEnzymes are used as environmentally friendly catalysts in many industrial applications, and are frequently immobilized in a matrix to improve their chemical stability for long‐term storage and reusability. Recently, it was shown that an atomic‐level description of proteins immobilized in a biosilica matrix can be attained by examining their magic‐angle spin...... hiện toàn bộ
Critical Size for O2 Dissociation by Au NanoparticlesChemPhysChem - Tập 10 Số 2 - Trang 348-351 - 2009
Alberto Roldán, Silvia González, Josep M. Ricart, Francesc Illas
AbstractDensity functional theory calculations predict that the presence of low‐coordination Au atoms is not enough to dissociate O2, that there is a common pathway for O2 dissociation on Au nanoparticles and that there is critical size for Au nanoparticles to dissociate O2 (see f...... hiện toàn bộ
Density Functional Theory Study of Hydrogen Adsorption in a Ti‐Decorated Mg‐Based Metal–Organic Framework‐74ChemPhysChem - Tập 17 Số 6 - Trang 879-884 - 2016

AbstractThe Ti‐binding energy and hydrogen adsorption energy of a Ti‐decorated Mg‐based metal–organic framework‐74 (Mg‐MOF‐74) were evaluated by using first‐principles calculations. Our results revealed that only three Ti adsorption sites were found to be stable. The adsorption site near the metal oxide unit is the most stable. To investigate the hydrogen‐adsorptio...... hiện toàn bộ
Characterization of a Poly‐4‐Vinylpyridine‐Supported CuPd Bimetallic Catalyst for Sonogashira Coupling ReactionsChemPhysChem - Tập 18 Số 14 - Trang 1921-1928 - 2017

AbstractCuPd bimetallic solvated metal atoms (SMA) synthesized by metal vapor synthesis (MVS) technique and supported on poly‐4‐vinylpyridine (PVPy) resin, showed significantly higher catalytic activity in Sonogashira‐type carbon–carbon coupling reactions than the corresponding monometallic Cu and Pd systems as well as their physical mixture. The analysis of the bi...... hiện toàn bộ
