The Czech BIORAF project employs the techniques of green chemistry for biomass utilization to high added-value products and energy sources. Refining it results in food supplements, fodders and fertilizers, new-generation biofuels and energy from the biomass of microbial, plant or animal origin. Biorefining is a unique approach for a new sustainable substitution of fossil fuels minimizing an adverse effect on the environment while exploiting the whole volume of biomass. and Pavel Topka.
The oldest and largest Czech scientific society in the field of chemistry, the Czech Chemical Society (ČSCH), is a constituent member of the European Association for Chemical and Molecular Sciences (EuCheMS) and has a wide range of activities. The society´s web pages http://www.csch.cz and its journal pages http://chemicke-listy.vscht.cz/ offer more information. and Bohumil Kratochvíl.
The International Year of Chemistry 2011 attracted chemistry women worldwide for a breakfast meeting on January 18, 2011. In addition to networking, the aim was to commemorate the fundamental role Marie Curie attained in chemistry on the 100th anniversary of her being awarded the Nobel Prize for Chemistry in 1911. The event was held in various centers worldwide including Prague. and Zuzana Sedláková.
We feature an interview in this issue with Professor Josef Michl, acclained chemist, who received his Ph.D. at the Czechoslovak Academy of Sciences in 1965 but left Czechoslovakia three years later. He became a full professor in 1975 at University of Utah. Professor Michl has held nearly one hundred visiting professorships and named lectureships, delivered hundreds of invited lectures at institutions and conferences, has served on many professional and editorial boards, advisory councils, and committees, and has organized several international meetings. Since 2006, he also has held an appointment at the Institute of Organic Chemistry and Biochemistry of the ASCR. He is a laureate of Wichterle Award, the Schrödinger and Porter Medals, the J. Heyrovský Gold Medal of the ASCR and Charles University, the Czech government Patria Award for Czech scientists working abroad, and the Marinus Smith Award from the University of Colorado for his work with undergraduates. He is also a member of the US National Academy of Sciences, the American Academy of Arts and Sciences, and the International Academy of Quantum Molecular Science and is an honorary member of the Czech Learned Society. and Sylva Daníčková.
"Člověk jako badatel nehraje se Satanem o svou duši, ale s přirodou o poznání a moc." William Crookes. Sir William Crookes (1832-1919) byl jedním z nejvýznamějších britských fyziků a chemiků druhé poloviny devatenáctého a začátku dvacátého století. Tento text se zabývá jeho životem a vědeckým odkazem, kterým je například objev thallia, zkoumání čtvrtého stavu hmoty, podíl na objevování řady vzácných plynů, vynález prvního radiometru a také spinthariskopu, jednoho z prvních detektorů ionizujícího záření. Některé Crookesovy myšlenky si ještě za jeho života našly cestu také k českému čtenáři a právě tyto texty jsou hlavním tématem našeho článku., Sir William Crooker (1832-1919) was one of the most notable British physicists and chemists active in the second half of the 19th century. The subject of this article is his life and scientific legacy, e.g. the discovery of thallium, exploration of the fourth state of matter, participation in discovering certain rare gases, or invention of the first radiometer and spinthariscope. Some ot his ideas vere presented to the Czech audience during the course of his life and it is these texts which are "the golden thread" of this article., Pavel Pecháček, Petr Průša., and Obsahuje seznam literatury
Článek ukazuje, jak nám zdánlivě jednoduché přístupy a nástroje založené na fyzikálních a chemických principech a poznatcích umožní přežít v nehostinných podmínkách mimo civilizaci. obecné úvahy jsou ilustrovány konkrétními příklady - rozděláváním ohně, čištěním a dezinfekcí vody atp., This article deals with using physics and chemistry to make possible our survival in the wilderness. Contemporary physics and chemistry is responsible for progress in the field of outdoor pursuits. Outdoor equipment and skills have become high-tech. Thus, use of basic physical and chemical principles in outdoor activities is now often overlooked although they can be of great use at moments when we lose technological superiority because of unexpected situations and events at extreme conditions. Then we are forced to improvise. Usefulness of applying physical and chemical principles is demonstrated on flame-resistant fiberglass wick, simple lighters, thermos used for cooking and sperilizing water, utilization electrolysis of brine for generating chlorine for water disinfection, use of PET bottles as simple pressurized filtration device for water purification, and so on., Ladislav Sieger., and Obsahuje bibliografii
