“…Moving from small-angle to wide-angle scattering, several software packages are available. With SimDiffraction, a tool for analyzing GIWAXS data from textured thin films has been established (Breiby et al, 2008), such as the crystalline structure of active layers of small-molecule solar cells (Gevaerts et al, 2014), and this has been applied to porous films as well (Chavez Panduro et al, 2014;Voss et al, 2014). As an alternative, GIXSGUI has been used for simulating space groups in GIWAXS (Jiang, 2014).…”

The complex nano-morphology of modern soft-matter materials is successfully probed with advanced grazing-incidence techniques. Based on grazing-incidence small-and wide-angle X-ray and neutron scattering (GISAXS, GIWAXS, GISANS and GIWANS), new possibilities arise which are discussed with selected examples. Due to instrumental progress, highly interesting possibilities for local structure analysis in this material class arise from the use of micro-and nanometer-sized X-ray beams in micro-or nanofocused GISAXS and GIWAXS experiments. The feasibility of very short data acquisition times down to milliseconds creates exciting possibilities for in situ and in operando GISAXS and GIWAXS studies. Tuning the energy of GISAXS and GIWAXS in the soft X-ray regime and in time-of flight GISANS allows the tailoring of contrast conditions and thereby the probing of more complex morphologies. In addition, recent progress in software packages, useful for data analysis for advanced grazing-incidence techniques, is discussed.

“…So far mesoporous alumina has been synthesized using both soft templates (including cationic 242 and anionic surfactants, 243 as well as nonionic block copolymers [244][245][246][247][248][249] ) and hard templates. This method to mesostructured materials has also been extended, with continuing success, to non-silica oxides.…”

Mesoporous solid bases are extremely desirable in green catalytic processes, due to their advantages of accelerated mass transport, negligible corrosion, and easy separation. Great progress has been made in mesoporous solid bases in the last decade. In addition to their wide applications in the catalytic synthesis of organics and fine chemicals, mesoporous solid bases have also been used in the field of energy and environmental catalysis. Development of mesoporous solid bases is therefore of significant importance from both academic and practical points of view. In this review, we provide an overview of the recent advances in mesoporous solid bases, which is basically grouped by the support type and each category is illustrated with typical examples. Cooperative catalysts derived from the incorporation of additional functionalities (i.e. acid and metal) into mesoporous solid bases are also included. The fundamental principles of how to design and fabricate basic materials with mesostructure are highlighted. The mechanism of the formation of basic sites in different mesoporous systems is discussed as well.
