Molecular hydrogen was encapsulated in the cages of clathrasil decadodecasil 3R (DD3R) during the hydrothermal synthesis of this microporous silicate. The crystalline structure of DD3R facilitates high-density hydrogen storage at ambient conditions.

The feasibility of the sodalite-type (SOD) structures, Si 6 O 12 :(all–Si), Na 3 Si 3 Al 3 O 12 :(Na–AlSi(3:3)), Al 3 P 3 O 12 :(AlP(3:3)), and Ge 6 O 12 :(all–Ge), as hydrogen storage media is assessed by calculating the hydrogen uptake isothe

The anisotropic self-diffusion of molecular hydrogen in the multiple cage clathrasil losod (LOS) is modeled by means of molecular dynamics (MD) simulations of up to 1 micros for the temperature range 900-1200 K while treating the framework as fully f

Porous, crystalline solids, built up from TO 4 (T = Al, Si, Ge, P) tetrahedra, are potentially attractive materials for the safe storage of significant amounts of hydrogen. In this study we concentrate on the large void volume sodalite framework type

The effect of UV-irradiation on (0 0 1) rutile wafers, used as a model support for in-situ zeolite A layer growth on TiO2-coated membrane supports, is reported. From previous studies it is known that UV-radiation increases the number of defect sites

Storage and transport of hydrogen constitutes a key enabling technology for the advent of a hydrogen-based energy transition. Main research trends on hydrogen storage materials, including metal hydrides, porous adsorbents and hydrogen clathrates, are

The synthesis of esters is an essential part of first- and second-year organic chemistry laboratory classes. To highlight the differences between two standard approaches towards esters, a set of experiments was developed. With these experiments the s
