Vibrational spectroscopy of zeolite complexes [PDF]
, 1985 Using infrared spectroscopy, studies of the interaction of small molecules {e.g. CO, C(_2)H(_2), CH(_3)CHO) with zeolites have been carried out. The work has resulted in the observation of both stable chemisorbed complexes and reacting species for which

Durable Fuel Cell Cathode Enabled by Pt Embedded Nanoscale Carbon Network via a Scalable Process
Carbon Energy, EarlyView.Platinum nanoparticles embedded nanoscale carbon network (Pt‐e‐Cn) are developed via a scalable flame spray pyrolysis process. Proton exchange membrane fuel cells (PEMFC) employing mesoporous Pt‐e‐Cn cathode electrocatalysts exhibit exceptional durability without compromising performance.

Transitioning Formamide Solvothermal Syntheses of MOFs to Less Toxic Solvents
Chemistry – A European Journal, EarlyView.Metal‐organic Frameworks (MOFs) are commonly synthesized in toxic formamide solvents. This study investigates the synthetic factors required for effective removal of formamides across various classes of MOFs, providing a foundation for designing new sustainable MOF syntheses.

Characterization of Zeolites exchanged with heavy metals as precursors of metal-ceramic composites [PDF]
, 2007 The reduction of metal (Fe3+ and Co2+)-exchanged A and X zeolites was studied by a temperature programmed reduction (TPR tecnique) in order to evaluate the reduction temperature of these samples.

Semiconducting Single‐Wall Antimony Oxide Nanotubes and Oxidotritelluridoantimonate(V) Anions
Chemistry – A European Journal, EarlyView.Antimony(V) binds directly to tellurium(−II) in the (SbOTe3)3− anion. The latter has been found between Sb2O3 nanotubes in a microporous cetineite structure. The Sb2O3 nanotube is positively polarized on its outer surface and negatively polarized on its inner surface, corresponding to a cylindrical capacitor. Substantial charge transfer from the anions

Computer simulation of the adsorption of chlorinated organics in zeolites. [PDF]
, 2006 Computer modelling techniques have been used to study the adsorption of three chlorinated hydrocarbons Dichloromethane, 1,2-Dichloroethane, and Trichloroethene in three different zeolite frameworks MFI, MOR and FAU. Calculations have been performed using

Chemistry – A European Journal, EarlyView.We report a reversible structural phase transition in a metal–organic framework (MOF) triggered by the exchange of coordinative guest molecules. This MOF consists of rigid 1D Pb–O rods as building units, forming a 3D framework with 1D pores. Guest exchange induces pronounced changes in both the Pb–O rod structure and the dimensionality of the framework.

Chemistry – A European Journal, EarlyView.Combining the chiral bispidine ligand L1 with MnCl2 affords coordination polymers (CPs) with an unusual topology for this family of compounds, consisting of orthogonally packed ribbon‐like one‐dimensional (1D) chains. Their behavior was investigated through single‐crystal‐to‐single‐crystal exchange with aromatic volatile organic compounds (VOCs) and ...
