Knut and Alice Wallenberg Foundation is almost doubling the annual budget of the research initiative Wallenberg Centre for Quantum Technology, WACQT, based at Chalmers University of Technology, Sweden. This will allow the centre to shift up a gear and set even higher goals - especially in its development of a quantum computer. Two international workshops will kick-start this new phase. Quantum technology has enormous potential and it is important that Sweden has the necessary skills in the area. During the short time since the center was founded, WACQT has built up a qualified research environment, established collaborations with Swedish industry and succeeded in developing qubits with proven problem-solving ability. We can look ahead with great confidence at what they will go on to achieve, says Peter Wallenberg Jr, Chair Knut and Alice Wallenberg Foundation.

Copper nanomaterials with a cubic shape so perfect that they form neatly aligned stacks when brought together have been created by researchers at KAUST. The cuboid copper nanoclusters, developed by rational design, are a new member of an exotic nanomaterial family that has shown many promising properties but has remained very hard to make. Copper nanomaterials are a class of materials that exhibit useful properties for the fields of photoluminescence and catalysis, says Ren-Wu Huang, a postdoc in Osman Bakr s lab, who led the research. There is great interest in synthesizing new copper nanomaterials to understand how their structure influences their function.

Modeling - Urban climate impacts
Researchers at Oak Ridge National Laboratory have identified a statistical relationship between the growth of cities and the spread of paved surfaces like roads and sidewalks. These impervious surfaces impede the flow of water into the ground, affecting the water cycle and, by extension, the climate. We ve shown that there is a specific mathematical shape to the relationship between a city s population and the total paved area, ORNL s Christa Brelsford said. Using that, we examined climate model predictions and determined they correctly represent some important attributes we know about cities.

Tokyo, Japan - Scientists from Tokyo Metropolitan University have developed a new method for making ordered arrays of nanoholes in metallic oxide thin films using a range of transition metals. The team used a template to pre-pattern metallic surfaces with an ordered array of dimples before applying electrochemistry to selectively grow an oxide layer with holes. The process makes a wider selection of ordered transition metal nanohole arrays available for new catalysis, filtration, and sensing applications.

Optical-resolution photoacoustic microscopy (OR-PAM), a new hybrid imaging technique, allows us to listen to the sound of light and see the color of biological tissue itself. It can be used for live, multicontrast functional imaging, but the limited wavelength choice of most commercial lasers and the limitations of the existing scanning methods have meant that OR-PAM can obtain only one or two different types of contrast in a single scan. These limitations have made multicontrast functional imaging time-consuming, and it s been difficult to capture the dynamic changes of functional information in biological tissues.
