EV charging approaches in remote regions – Analysis of capacity, cost and logistics

With countries across the world finding pathways to counter CO2 emissions, sustainable mobility has become a critical topic for leaders, policymakers, and industries. The development of Battery Electric Vehicles (BEV’s) is seen as an important and effective way through which reliance on fossil fuels and thereby related CO2 emissions can be reduced. Statistics show that the number EV’s on the roads

Dean carrie abstract

Abstract Abstract Key words: biopolymers, polylactic acid, PLA, Mater-bi, renewable packaging, sustainable packaging. This study investigates the possibility of making Tetra Pak non-aseptic packaging more sustainable by replacing the currently used fossil-based low-density polyethylene (LDPE) laminate, with a renewable starch-based polymer laminate. Two starch-based materials are studied: polylact

Effect of carbon dioxide and temperature on H2 producing cultures of the extreme thermophile, Caldicellulosiruptor saccharolyticus

Carbon dioxide could replace nitrogen gas as stripping gas for the production of H2 by the extreme thermophile, Caldicellulosiruptor saccharolyticus, provided that the pH is kept below 7.0. Above this pH, ≥77 mM sodium bicarbonate will be introduced as an extra salt burden to the culture. High concentrations of sugars and salts contribute each to the inhibition of growth and H2 production, which i

PEPPSI-type Complexes of Palladium and Platinum: : Investigation of Properties and Applications in Catalysis

Catalysis is a powerful tool to highly efficient production of desired newchemicals by acceleration of a chemical reaction rate. Special compounds used forthis purpose are called catalysts; they induce a change in the chemicalenvironment without being consumed during the process. Catalysis affects manyfields of life leading to a decrease of the energy use, less pollution, fewer sideproducts and loCatalysis is a powerful tool to highly efficient production of desired newchemicals by acceleration of a chemical reaction rate.

Growth and hydrogen production characteristics of Caldicellulosiruptor saccharolyticus on chemically defined minimal media

Caldicellulosiruptor saccharolyticus is an extreme thermophilic bacterium recognized for its saccharolytic ability and superior ability to produce high yields of hydrogen. However,most studies have been made using yeast extract (YE) as a rich but expensive nutrient source. For the first time, we show that C. saccharolyticus is able to grow on defined minimal media, including essential vitamins, pr

Xenergic

 Xenergic is developing technology intended to reduce electricity consumption by more than half in certain types of memory circuits, with the aim of prolonging battery life in connected products. The technology deals with a new type of SRAM memory developed at the Department of Electrical and Information Technology at Lund University’s Faculty of Engineering. SRAM is a type of computer memory whic

Temperature-dependent Study for Hydrogen Crossover in a Polymer Electrolyte Membrane Used in a PEFC

Significance efforts are underway to improve fuel cell performance, with the Polymer Electrolyte Membrane (PEM) being an essential component of Polymer Electrolyte Fuel Cells (PEFCs). The losses within the PEM can be measured through hydrogen crossover. The temperature is a critical variable that directly affects the hydrogen crossover. In this study, the hydrogen crossover and corrected current d

Theoretical Particle Physics

The Theoretical Particle Physics group is mainly active in particle physics phenomenology. Work which relates theory to quantitative predictions for collider experiments. The group is subdivided into smaller, more informal, research groups centered around different research areas, which again are clustered into different categories, centered around the individual researchers' projects. They includ

Importance of proximal hydrogen bonds in haem proteins.

We have used the density functional B3LYP method to study the effect of hydrogen bonds from the histidine ligand in various haem proteins to carboxyl groups or to the carbonyl backbone. Hydrogen bonds to carbonyl groups (encountered in globins and cytochromes, for example) have a small influence on the geometry and properties of the haem site. However, hydrogen bonds to a carboxyl group (encounter

Carbon capture

Absorption of carbon dioxide occurs in several processes. In the production of biogas or synthetic natural gas from biomass, carbon dioxide must be removed from the produced gas before it can be used as a vehicle fuel or injected into the natural gas network. In the chemical industry, there is often a need to separate carbon dioxide from gas streams. Carbon dioxide capture can also be used for Car

Optical Studies For Synchrotron Radiation Beamlines

Popular Abstract in English Among the large variety of experiments performed in science, a common one is to pass a light beam through a sample, the object to be studied, and to study the outcomes of the light-sample interaction. Many light sources have been used for this purpose, like light bulbs and lasers. A modern light source used nowadays is the so-called storage ring. In the storage rings elSynchrotron radiation sources have greatly contributed to the progress in many fields of science. The development of the storage ring technologies has made possible to obtain very low emittance electron beams, which together with the use of undulators allow guiding a very high photon flux into a very small spot required by the experiments. Development of the sources has been accompanied with equa

Solar energy conversion in molecular and hybrid systems

Molecular-based systems including organic semiconductors (pi-conjugated polymers), metal complexes, organic-inorganic perovskites and other hybrid systems are all of great interest for emerging solar energy conversion applications. Current interests include fundamental investigations of photoinduced processes in a range of applications toward both photovoltaic and photocatalytic applications that
