For the first time, researchers have demonstrated the creation of a beam of nanodroplets capable of delivering a variety of biological samples, from cell organelles to single proteins, virtually free from any contaminations, to the focus of an X-ray laser which can be used to image them.
Nanosized magnetic particles called skyrmions are considered highly promising candidates for new data storage and information technologies. Now, physicists have revealed new behaviour involving the antiparticle equivalent of skyrmions in a ferromagnetic material. The results are published in Nature Electronics.
In a new article, published in Nature Materials, researchers from Beijing, Uppsala and Jülich have made significant progress allowing very high resolution magnetic measurements. With their method it is possible to measure magnetism of individual atomic planes.
Hydrogen gas has long been proposed as a promising energy carrier for future energy applications, but generating the gas from water has proved inefficient. In an article in the journal Energy and Environmental Science, scientists at Uppsala University now present an alternative, interdisciplinary method based on principles from nature.
Inspired by the way people move at heavy metal concerts, an international team of researchers from Uppsala University and Harvard University have learned how to spot danger zones in mass gatherings before disaster strikes.
Being able to determine magnetic properties of materials with sub-nanometer precision would greatly simplify development of magnetic nano-structures for future spintronic devices. In a new study Uppsala physicists make a big step towards this goal - they propose and demonstrate a new measurement method capable to detect magnetism from areas as small as 0.5 nm2.
For the first time, researchers have revealed the nanostructure of the mesoporous magnesium carbonate Upsalite® and pore size control was achieved without organic templates or swelling agents. By controlling the pore structure of the material the amorphous phase stabilisation exerted on poorly soluble drug compounds can be tuned and the drug delivery rate can be tailored.
Uppsala physicists have in an international collaboration developed a new method for creating laser pulses which are shorter, have much higher intensity and cover the THz frequency range better than current sources. The study is published today in the authoritative journal Nature Photonics and is of great importance to materials research.
Electrochromic windows, so-called ‘smart windows’, share a well-known problem with rechargeable batteries – their limited lifespan. Researchers at Uppsala University have now worked out an entirely new way to rejuvenate smart windows which have started to show signs of age. The study, published in the distinguished science journal Nature Materials, may open the way to other areas of application.
The effect of Internet on our lives and society is a constant topic of interest for politicians, business leaders, the media and the general public, an interest that has generated a substantial body of research on the use of ICT. In a newly published dissertation, ICT researcher Håkan Selg highlights the need for theoretical awareness to strengthen the role of research as a source of knowledge.
Present-day lithium batteries are efficient but involve a range of resource and environmental problems. Using materials from alfalfa (lucerne seed) and pine resin and a clever recycling strategy, Uppsala researchers have now come up with a highly interesting alternative. Their study will be presented soon in the scientific journal ChemSusChem.
More than 80 percent of all drug candidates in the pharma R&D suffer from poor solubility and are therefore rejected early in the drug discovery process. Now Uppsala University researchers show that the new material Upsalite®, has great potential for development of new formulations of these rejected drugs.
In a new study a team of researchers lead from Uppsala University show how lactase persistence variants tell the story about the ancestry of the Khoe people in southern Africa. The team concludes that pastoralist practices were brought to southern Africa by a small group of migrants from eastern Africa. The study is now published in Current Biology.
Researchers at the Division of Nanotechnology and Functional Materials, Uppsala University have developed a paper filter, which can remove virus particles with the efficiency matching that of the best industrial virus filters. The paper filter consists of 100 percent high purity cellulose nanofibers, directly derived from nature.
A novel material with world record breaking surface area and water adsorption abilities has been synthesized by researchers from Uppsala University, Sweden. The results are published today in PLOS ONE.
New research results from Uppsala University instil hope of efficient hydrogen production with green algae being possible in the future, despite the prevailing scepticism based on previous research. The study, which is published today in the esteemed journal PNAS, changes the view on the ability of green algae – which is good news.
A little more than a year ago a research team started to develop a vital part of a Finnish invention – an electric solar wind sail for interplanetary journeys. Now, a prototype has been successfully manufactured and tested.
An advanced chip that swiftly and with extremely high sensitivity can measure 92 different tumour proteins from 92 different patients is now available at SciLifeLab in Uppsala. The new technology will become an important resource for researchers and companies developing diagnostics for different illnesses.
Researchers and doctoral students from Uppsala University have today installed the first 6.7 metre long generator in what will become a wave power farm in Lysekil, Sweden.
Journalists are welcome to the river Dalälven, in the rural Swedish town of Söderfors, when the first experimental plant for marine current power will be installed on March 7. The aim is to develop new technology for utilising renewable marine current power as a means for producing electricity.
