Lately the effect of global warming has been generally accepted and the interest of renewable resources is constantly increasing. Hydrogen would serve this purpose as an alternative fuel; however, storage is a challenging task and there is a need for new materials, with higher hydrogen capacity and lower cost. The concept of high-entropy alloys (HEAs) […]
Proton conducting oxides, and in particular acceptor doped BaZrO3, are materials of great interest because of their huge potential as electrolyte in several energy related technologies, such as hydrogen sensors, membrane reactors, steam electrolyzers, and intermediate-temperature (200 – 500 °C) solid oxide fuel cells. A key requirement for the electrolyte is a high proton conductivity […]
Many low molecular weight drugs, like classical surfactants, contain both hydrophobic and hydrophilic groups. However, due to their lower molecular weight and less distinct separation into hydrophobic and hydrophilic regions, the self-assembly of such drugs in aqueous solutions is less easy to describe in general terms. To gain more understanding of the interaction between such […]
In recent year, new therapeutic modalities involving delivery of biological molecules such as RNA, peptides and oligonucleotides have shown promising results to treat diseases that are currently hard to tackle with standard small molecules approaches. As an example, last year Alnylam announced the first therapy using small interference RNA (siRNA) approved by the Federal Drug […]
The transition from the current two-dimensional data storage and logic schemes to three-dimensional data structures could significantly improve the performance and capacity of electronic devices. Instead of simply storing and manipulating data in a two-dimensional array of elements, one can envisage stacking data bits on top of each other, thus greatly enhancing the data density. […]
Multilayered Graphene Oxide (GO) materials such as membranes and thin films are known for their potential for selective ion permeation, nano-filtration, water desalination and gas barrier properties. Many recent studies have aimed at demonstration of selective permeation of certain ions and molecules through GO membranes. Membrane tests were demonstrated to be successful for relatively thin […]
Ionic liquids (ILs) have been identified as promising replacements for conventional lubricants. Their ionic nature and wide electrochemical windows present a new horizon for electrical energy storage solutions and tribotronic lubrication, whereby the friction coefficient is controllable though use of an electric field. However, due to the high production costs the commercialisation of IL lubricants […]
The overall goal of the Super ADAM project is to provide state of the art neutron reflectivity to the Swedish research community. Thanks to a major upgrade started in 2013, Super ADAM has crucial features required to meet contemporary challenges in reflectometry. Super ADAM is operated by Uppsala University and is financed by the Swedish […]
Lipids are the main components of cellular membranes. The main building blocks of the membranes that surround cells are lipid mixtures that form lamellar phases. However, lipids have a rich phase behaviour ranging from micellar, hexagonal or cubic to lamellar and, further, to the reversed counterparts, which are also utilised in many biological systems. The […]
Rapid growing demands on electric-power based automotive transportation, grid applications and electronic devices require development of sustainable rechargeable batteries. This also arises from an urgent need to decrease CO2 emissions and to implement renewable energies into society. Unfortunately, improvements to battery materials has been slow and discovery of new materials with improved properties even slower. […]
Why is it so that individuals with good cholesterol values develop cardiovascular disease, whilst other individuals with poor values remain healthy? Cholesterol and other fats are transported through the blood via specific transporters called lipoproteins. The most well-known are the so called “good” and “bad” cholesterol. Understanding these particles in structure and composition and the way they interact with artery wall is crucial in understanding this disease, the main killer of the West. Such knowledge would aid in improving diagnostic tools as well as in development of new drugs.
Professor Martin Andersson (Chalmers) — Today, water purification typically includes a size-exclusion based filter that is specialized in removing a certain number of common water pollutants. But these filters do not remove all the pollutants present in water. So why not develop a filter that produces clean water regardless of pollutant? Guess what – nature already did.
Professor Adrian Rennie (UU) –– New research using the INTER reflectometer at ISIS Neutron and Muon Source has revealed how plant proteins can be used to stick particles to solid surfaces, opening up a plethora of potential industrial applications.
