Over the last 15-20 years a wide range of new porous catalytic materials has been discovered in the wake of major developments in mesostructured materials and hybrid porous solids such as metal organic frameworks（MOFs）.These two developments have both enormous potential to produce catalyst supports and *** may be argued that most existing industrial catalysts may be revisited for improvement taking advantage of the novel materials.

以介孔硅SBA-15为模板,焦糖和呋喃醇为碳源,通过多种浇注法制备介孔炭材料。采用低温氮吸附、透射电镜和X射线小角衍射分析模板及介孔炭的织构。结果显示合成的介孔炭成功地复制了SBA-15的结构。以制备的介孔炭作载体担载钴钼合成了加氢脱硫催化剂,利用X射线能谱、透射电镜能量分布谱及一氧化氮化学吸附评估了催化剂的活性及活性点分布,结果表明介孔炭担载的催化剂活性高于活性炭担载的同类催化剂。

作者： serge V.NAUGOLNYKH Geological Institute of Russian Academy of Sciences Pyzhevsky per.7119017 MoscowRussia

Field work focused on the Kuedinskie Kluchiki locality, Perm region, Urals, Russia, which contains a rich assemblage of diverse fossil organisms including higher plants(equisetophytes, pteridosperms, ginkgophytes, conifers, vojnovskyans) represented by stems, leaves and reproductive organs;invertebrates(mollusks, arthropods), and tetrapods(temnospondyl amphibians, seymouriamorphs, cotylosaurs, synapsids, diapsids), as well as bony fishes. General characteristics of the taxonomical composition of the Kuedinskie Kluchiki locality are given. A new peltaspermalean pteridosperm taxon, Compsopteris longipinnata sp. nov., and a voltzialean conifer Archaeovoltzia kuedensis sp. nov. are described. General considerations on the paleoecologic and paleogeographic conditions of the Kuedinskie Kluchiki locality origin are given.

The food and nutrition situation in Burkina Faso, like most developing countries in sub-Saharan Africa, is marked by growing food vulnerability. The majority of local dishes are being abandoned in favor of a minority of imported cereal dishes and other ultra-processed foods. This minority of cereal foods is blamed for stunted growth in children, while ultra-processed foods are linked to chronic diseases such as hypertension, certain types of diabetes and cancer. Knowledge of the nutritional value of local foods is needed to determine their nutritional quality. The aim of this study was to determine the nutritional values of local dishes based on millet, sorghum and cowpea in the Centre-North region. The methodology consisted of making an inventory of millet-, sorghum- and cowpea-based dishes using focus groups made up of women and men from three age groups comprising young people, adults and the elderly in the communes of Lebda and Boussouma. The dishes were reproduced, and standard biochemical methods were used for nutritional characterization. A total of 34 dishes were inventoried, including 16 millet/sorghum-based dishes, 8 cowpea-based dishes and 10 dishes composed of millet/sorghum and cowpea or leaves. The mean protein, carbohydrate, ash and iron contents per 100 g DM of the three types of dishes were significantly different (p ≤ 0.05), ranging respectively from 13.61 to 22.63 g, 70.76 to 80.88 g, 1.87 to 5.96 g and 7.67 to 12.06 mg. Those for lipid, energy and zinc were not significantly different, ranging from 5.51 to 6.56 g, from 427 to 433 Kcal and from 2.98 to 3.32 mg respectively. Cowpea-based and mixed dishes cover the nutritional requirements for protein, carbohydrates, iron, zinc and energy recommended for children and adults. The consumption of mixed dishes and cowpea-based dishes could be promoted by nutritional policy to reduce stunting and recommended to obese, hypertensive and diabetic people as part of their diet.
