1. 1. Molecular Copper and Ruthenium Water Oxidation Electrocatalysts for Light-Driven Water Splitting

   Författare :Ludovico Riccardi; Sascha Ott; Rene Janssen; Jarl Van der Vlugt; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Water oxidation; Molecular catalyst; Electrocatalyst; Water splitting; Electrolyzer; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

   Sammanfattning : In recent years, there has been a growing awareness of the need to transition to renewable energy to mitigate the effects of climate change and reduce greenhouse gas emissions. Governments, businesses, and individuals are investing in renewable energy infrastructure and technologies to create a more sustainable energy future. LÄS MER

3. 2. P-adic dynamical systems and van der Put basis technique

   Författare :Ekaterina Yurova Axelsson; Andrei Khrennikov; Franco Vivaldi; Linnéuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dynamical systems; p-adic; 1-Lipschitz; measure-preserving; ergodicity; spheres; uniformly differentiable; Tillämpad matematik; Applied Mathematics;

   Sammanfattning : Theory of dynamical systems in fields of p-adic numbers is  an important part of algebraic and arithmetic dynamics. The study of p-adic dynamical systems is motivated by their applications in various areas of mathematics, e.g., in physics, genetics, biology, cognitive science, neurophysiology, computer science, cryptology, etc. LÄS MER

4. 3. On thermodynamic and kinetic constraints in autotrophic metabolism

   Författare :Markus Janasch; Elton P. Hudson; Bas Teusink; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; autotrophic metabolism; cyanobacteria; microbial metabolic engineering; computational systems biology; biochemical thermodynamics; kinetic modelling; Bioteknologi; Biotechnology;

   Sammanfattning : Earth has entered a new geological epoch, the Anthropocene, defined by humanity’s impact on the environment with increased emissions of CO2 due to burning of fossil resource as a major contributor. To ensure a sustainable future, humanity has to move towards a circular economy, where released CO2 is re-captured and turned into resources. LÄS MER

5. 4. Stroke during cardiac surgery : risk factors, mechanisms and survival effects

   Författare :Magnus Hedberg; Karl Gunnar Engström; Patrik Boivie; Jan van der Linden; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; stroke; cardiac surgery; adult; risk factors; mortality; embolism; aortic cross-clamp; aortic cannulation; Thoracic surgery; Thoraxkirurgi; kirurgi; särskilt thoraxkirurgi; Thoracic and Cardivascular Suregery;

   Sammanfattning : Introduction: Neurological complications and stroke in association with cardiac surgery is a serious problem. The stroke event can occur during surgery (early stroke) or in the postoperative period with a symptom free interval (delayed stroke). LÄS MER

7. 5. Thoracic Aortic Surgery : Epidemiology, Outcomes, and Prevention of Cerebral Complications

   Författare :Christian Olsson; Stefan Thelin; Jan van der Linden; Uppsala universitet; []
   Nyckelord :Surgery; Aorta; Thoracic; Aortic aneurysms; Aortic disease; Cardiovascular surgical procedures; Epidemiology; Registries; Treatment outcome; Survival analysis; Cerebral infarction; Near-infrared spectroscopy; Quality of life; Perfusion; Kirurgi;

   Sammanfattning : The mortality of thoracic aortic diseases (mainly aneurysms and dissections) is high, even with surgical treatment. Epidemiology and long-term outcomes are incompletely investigated. Stroke is a major complication contributing to mortality, morbidity, and possibly to reduced quality of life. LÄS MER
