Nanowires have many interesting properties that are of advantage for solar cells, such as the epitaxial combination of lattice-mismatched materials without plastic deformation. This could be utilized for the synthesis of axial tandem-junction nanowire solar cells with high efficiency at low material cost. Electron-beam-induced current measurements have been used to optimize the performance of sing

III-V semiconductor-based planar multi-junction solar cells synthesized to match the solar spectrum, increase absorption, and reduce thermalization loss are today's world-record efficiency solar cells. Realizing similarly performing multi-junction III-V nanowire (NW) solar cells would require significantly less material and is more sustainable at lower cost than planar solar cells. The NW geometry

Despite improvements, lung transplantation remains hampered by both a scarcity of donor organs and by mortality following primary graft dysfunction (PGD). Since acute respiratory distress syndrome (ARDS) limits donor lungs utilization, we investigated cytokine adsorption as a means of treating ARDS donor lungs. We induced mild to moderate ARDS using lipopolysaccharide in 16 donor pigs. Lungs were

When engaging in international collaboration, researchers and research institutions have to relate to a great range of differences in legislation, scientific practices, incentive systems, and cultural norms. The research landscape has become even more complex in the last decade, and the gray zones at the intersections of a diverse set of institutional contexts may be used to push boundaries. The f

Spark ablation is an established technique for generating aerosol nanoparticles. Recent demonstrations of compositional tuning of bimetallic aerosols have led to a demand for on-line stoichiometry measurements. In this work, we present a simple, non-intrusive method to determine the composition of a binary AuAg nanoparticle aerosol on-line using the optical emission from the electrical discharges.

Ammonia (NH3) is a promising carbon-free energy carrier. Co-firing of ammonia in solid fuel-fired facilities is a feasible solution to reduce carbon dioxide (CO2) emissions. Solid fuels, such as coal and biomass, contain various trace elements, such as alkali metals and sulfur, which are released to the gas phase during combustion. Experimental characterization and modeling are used to study the p

PURPOSE: Children with cerebral palsy (CP) are at risk of cognitive impairments and need to be cognitively assessed to allow for individualized interventions, if applicable. Therefore, a systematic protocol for the follow-up of cognition in children with CP, CP Cog, with assessments offered at five/six and 12/13 years of age, was developed. This report presents and discusses assessment practices i

Accessing embedded test and monitoring circuitry (the so-called embedded instruments) in in-field products can reduce maintenance and diagnostics costs. Performing such access can be facilitated when done over an internal system bus, due to that it might be faster and less cumbersome to reach a system processor (on an in-field product) over a network interface, compared with the effort and speed o

This chapter articulates a strategic canvas for degrowth, based on a dialogue with the work of Erik Olin Wright. It argues that degrowth strategies for social- ecological transformation need to combine several strategic approaches, reflecting the plurality of degrowth as a movement. To support the myriad of bottom-up alternatives that are already out there, degrowth actors should put a special emp

Disability scholars have recently proposed that republican theory is relevant to think about justice in relation to disability. Following in their footsteps, this article submits that the republican conception of freedom as non-domination provides a fresh angle to legitimise disability rights in terms of justice and prevent their interpretation as charity or privileges. This proposition takes its
