Katalys är ryggraden i många processer i vardagen. Även människokroppen styrs huvudsakligen av katalysatorer. Detta viktiga koncept tillåter oss att på ett miljövänligt sätt konvertera råmaterial som råolja och naturgas till värdefulla och oersättliga produkter, till exempel motorbränslen, läkemedel och agrokemikalier. En katalysprocess drivs av en katalysator, vilket således är en substans som, uNew classes of N-heterocyclic carbene-palladium(II) complexes containing either a vinyl group in different positions or an anthracene tag in the backbone of the N-heterocycle were synthesized and fully characterized. The vinyl based complexes were copolymerized with divinylbenzene to fabricate robust polymer-supported NHC-Pd(II) systems, while the anthracene based complexes were π-stacked onto the

Parkinson’s disease is a neurodegenerative affliction to which researchers have long striven to find a cure. The human embryo is a source of vital cells used in regenerative medicine, as well as a powerful symbol of life. Using foetal cells from aborted embryos for transplantation to the brains of Parkinson patients is an avenue that has been explored by neuroscientists on and off for the last thi

PurposeThe aim of the present study was to identify the most physically demanding work tasks for Swedish ground combat soldiers through the development and application of a questionnaire survey. This is the first in a series of studies aiming to describe the development process and validation of physical selection standards in the Swedish armed forces.MethodsBased on procedural documentation, comb

The setting (distance between mantle and concave ring) of the Hydrocone cone crusher is altered, even with the crusher operating at full load, by lifting or lowering the mantle by means of a hydraulic piston (Hydroset). Modern developments in the field of electronics and microcomputers have made it possible to design a small, reliable and very sophisticated system for automatic regulation of the s

Changes in farming practices over the past century have had negative influence on farmland biodiversity. Organic farming excludes most agrochemicals, such as inorganic fertilisers and synthetic pesticides, and can be an alternative to conventional farming. A recent meta-analysis indicates that there is on average 30% higher species richness on organically managed farmland compared to conventionall

A novel S-scheme photocatalytic heterojunction composite nanomaterial is developed by integrating zero-dimensional WO3 quantum dots (WQDs) on two-dimensional ultrathin CdIn2S4 (CIS) nanosheets with the aim of fostering carrier separation, enhancing the performance of carrier interface transport, minimizing carrier distance transport, and achieving effective photocatalytic CO2 reduction. The compos

BACKGROUND: (Z,E)-9,12-tetradecadienyl acetate (ZETA, Z9,E12-14:OAc) is a major sex pheromone component for many stored-product moth species. This pheromone is used worldwide for mating disruption, detection, monitoring, and mass trapping in raw and processed food storage facilities. In this study, we demonstrate the biological production of ZETA pheromone by engineered yeast Saccharomyces cerevis

There has been a strong quest for mapping and assessing ecosystem services (ES) to support governance. Yet, the institutional landscape that governs ES provision across multiple contexts has received less attention. We fill this research gap by developing and operationalising a framework for the analysis of policy documents that address European forest ES provision. By coding and analysing referen

We consider the pebble game on DAGs with bounded fan-in introduced in [Paterson and Hewitt '70] and the reversible version of this game in [Bennett '89], and study the question of how hard it is to decide exactly or approximately the number of pebbles needed for a given DAG in these games. We prove that the problem of deciding whether s pebbles suffice to reversibly pebble a DAG G is PSPACE-comple

Sustainably produced renewable biomass has the potential to replace fossil-based feedstocks, for generation of biobased fuels and chemicals of industrial interest, in biorefineries. In this context, seaweeds contain a large fraction of carbohydrates that are a promising source for enzymatic and/or microbial biorefinery conversions. The thermoanaerobe Thermoanaerobacterium AK17 is a versatile ferme

How to maintain and enhance cognitive functions for both aged and young populations is a highly interesting subject. But candidate memory-enhancing reagents are tested almost exclusively on lesioned or aged animals. Also, there is insufficient information on the type of memory these reagents can improve. Working memory, located in the prefrontal cortex, manages short-term sensory information, but,

Sb-based semiconductors are critical p-channel materials for III-V complementary metal oxide semiconductor (CMOS) technology, while the performance of Sb-based metal-oxide-semiconductor field-effect transistors (MOSFETs) is typically inhibited by the low quality of the channel to gate dielectric interface, which leads to poor gate modulation. In this study, we achieve improved electrostatics of ve

We provide evidence of a positive effect of major infrastructure development on international trade, using the opening of the fixed link between Denmark and Sweden in 2000 (The Oresund Bridge) as a quasi-natural experiment. Our Synthetic Control Method (SCM) constructs a counterfactual Danish-Swedish trade relationship, which represents bilateral trade in the absence of the bridge. Evaluating actu

Popular Abstract in Swedish Moder natur har i tusentals år varit en fantastisk källa till biologiskt aktiva substanser mänskligheten utnyttjat för att bota och förebygga sjukdomar. Från början användes olika beredningar och avkok från växter funna i närområdet som erfarenheten visat hade effekt mot åkomman man ville behandla. Detta har i modern tid utvecklats till att vi idag på ett systematiskt sIn 2005 two research groups independently reported the isolation of a series of structurally intriguing C-19 terpenolides from the plants Thapsia transtagana and Thapsia garganica. The compounds were shown to be potent inhibitors of the sarco/endoplasmic reticulum Ca2+-ATPases. The interesting biological properties and the unique structural characteristics of the transtaganolides/basiliolides (the

The present research was focused on the phytochemical research of Bolivian plants; a) two medicinal ones Aniba canelilla and Iryanthera juruensis, both plants showed to have compounds with biological activity in different fields. Even though Aniba canelilla was studied before, new compounds were identified in this investigation. The different active compounds found in Iryanthera juruensis seems to
