Mimicking High-Silica Zeolites: Highly Stable Germanium- and Tin-Rich Zeolite-Type Chalcogenides

Abstract: High-silica zeolites, as exemplified by ZSM-5, with excellent chemical and thermal stability, have generated a revolution in industrial catalysis. In contrast, prior to this work, high-silica-zeolite-like chalcogenides based on germanium/tin remained unknown, even after decades of research. Here six crystalline high-germanium or high-tin zeolite-type sulfides and selenides with four different topologies are reported. Their unprecedented framework compositions give these materials much improved thermal and chemical stability with high surface area (Langmuir surface area of 782 m2/g–1) comparable to or better than zeolites. Among them, highly stable CPM-120-ZnGeS allows for ion exchange with diverse metal or complex cations, resulting in fine-tuning in porosity, fast ion conductivity, and photoelectric response. Being among the most porous crystalline chalcogenides, CPM-120-ZnGeS (exchanged with Cs+ ions) also shows reversible adsorption with high capacity and affinity for CO2 (98 and 73 cm3 g–1 at 273 and ...

Barriers to Mental Health Care Utilization for U.S. Cambodian Refugees

Abstract: Asian Americans encounter barriers to mental health care, some of which are structural, whereas others may be cultural. Using data from a probability sample (N = 490) drawn from the largest Cambodian refugee community in the United States, the authors assessed the extent to which structural and cultural barriers were experienced. Surprisingly, a relatively small proportion endorsed commonly cited cultural barriers such as distrust of Western care (4%) and greater confidence in alternative care (5%), whereas most endorsed structural barriers such as high cost (80%) and language (66%). Among those with a probable diagnosis, a similar pattern was found. Findings suggest that structural, not culturally based, barriers are the most critical obstacles to care in this U.S. Cambodian refugee community.

A meta-analysis of the effects of attending religious schools and religiosity on black and hispanic academic achievement

Abstract: Using meta-analysis, this study sought to determine the effects of religious schooling and personal religious commitment on African American and Hispanic students’ academic achievement. The results indicate that religious schooling and religious commitment each have a positive effect on academic achievement and school-related behavior. In the case of religious schooling, the effect sizes that emerged for religious schooling tended to be larger for older children. The effect sizes for religious schooling were evenlarger for school-related behavior thanthey were for academic achievement. The significance of these results is discussed.

Automated unmanned rental system and method

Abstract: An automated unmanned rental system enables the automatic tracking of rental activity and equipment movement Each unmanned rental site has a computer system that monitors rental activity and monitors the available inventory and the rented, or checked out, inventory, and automatically generates invoices for items rented The computer system controls an RFID tracking system that utilizes the RFID tags on each piece of audio visual equipment in cooperation with one or more antennas The antennas send and receive signals that interact with the RFID tags when the equipment containing the RFID tag passes through a portal The computer system has a user interface to allow for associating equipment rental activity with a user and a reference document A reporting module may automatically communicate equipment movements A security alarm module may trigger an audible alarm under defined circumstances

Framework Cationization by Preemptive Coordination of Open Metal Sites for Anion-Exchange Encapsulation of Nucleotides and Coenzymes.

Abstract: Cationic frameworks can selectively trap anions through ion exchange, and have applications in ion chromatography and drug delivery. However, cationic frameworks are much rarer than anionic or neutral ones. Herein, we propose a concept, preemptive coordination (PC), for targeting positively charged metal-organic frameworks (P-MOFs). PC refers to proactive blocking of metal coordination sites to preclude their occupation by neutralizing ligands such as OH(-) . We use 20 MOFs to show that this PC concept is an effective approach for developing P-MOFs whose high stability, porosity, and anion-exchange capability allow immobilization of anionic nucleotides and coenzymes, in addition to charge- and size-selective capture or separation of organic dyes. The CO2 and C2 H2 uptake capacity of 117.9 cm(3) g(-1) and 148.5 cm(3) g(-1) , respectively, at 273 K and 1 atm, is exceptionally high among cationic framework materials.
