A great effort has been focused on the development of a new alloy that can operate over $700 \, \mathrm{ยฐC}$ and can be processed by normal industrial wrought techniques, mainly for aircraft engines and gas turbine applications. VDM Alloy 780, a Ni-based superalloy (NiCoTiAlNbCrMoNiFe), is a promising candidate for this high-temperature application that require e.g. good mechanical properties....

Organic solar cells have attracted increased attention due to their advantages in tunable characteristics, low-cost manufacturing processes and flexibility, which opens up a promising alternative for conventional photovoltaics. Recently the most widely investigated bulk heterojunction donor-acceptor system of P3HT:PCBM was doped with iron oxide nanoparticles, resulting in an increase of...

phospholipid-based bilayers are widely used as model systems for studying the more complicated biological cell membranes, providing information about their structure and interactions. In particular, we are interested in understanding the effect of drugs on phospholipid-based membranes, i.e. the action mechanism, and the eventual toxicity when administered at high concentrations. This knowledge...

Electricity is needed in many situations of our daily life at many different locations around the globe. Solar energy has the major advantage that the conversion process light/energy is simply available during daylight. It does not have to be actively transported or stored and is free of political control. Therefore, a strong interest in solar energy conversion has manifested over the last...

Blends of semiconducting polymers and inorganic semiconductor nanocrystals, like quantum dots (QDs), have started to attract intensive interests because of their inexpensive costs and the abilitiy of being solution processed. Both facts render them very promising candidates for next generation organic photovoltaics. Hybrid bulk heterojunction (BHJ) solar cells integrated with CuInSexS2-x...

Many present problems regarding the safety of liquid electrolytes in lithium-ion batteries may potentially be overcome by the use of solid-state polymer electrolytes. Polystyrene-block-polyethylene oxide PS-b-PEO diblock copolymer (DBC) electrolyte have been recently investigated as a membrane for Li-ion battery. The performance of these DBC electrolytes strongly depends on its morphology,...

Organometal halide perovskites mark a paradigm shift in photovoltaic research, as they combine high power conversion efficiencies with easy processing and cheap, abundant precursor materials making them a promising contender for other photovoltaic technologies. The commercial application of perovskite solar cells, however, is so far impeded by fundamental understanding lacking behind this fast...

Organometal halide perovskite based solar cells have emerged as the fastest-advancing photovoltaic technology to date, reaching certified solar cell efficiencies of up to 22.1%. Recently, the focus of research broadened beyond high efficiencies to key values like prolonged device lifetime and stability that are required for industrial implementation. A novel perovskite cell architecture...

Thermoelectric generators are a promising approach in renewable energies, as they are able to convert waste heat into electricity. Possible applications are large scale applications like recovering the waste heat of a car engine as electricity as well as niche applications like using the heat emitted by human skin to drive a watch.[1]
In practice, a thermoelectric generator traditionally...

As the need for sustainable energy sources is steadily increasing, the concept of photovoltaics has attracted both scientific and economic interest. Whereas conventional semiconductor-based solar cells are already well researched and their efficiencies are promising, their energy need for the mere production and their lack of versatility remain a major drawback. Therefore, concepts are needed,...

Organic light emitting diodes (OLED) are reaching inner quantum efficiencies close to 100%, but the overall efficiency of conventional devices is limited to about 20% mainly by the photon extraction. One approach to overcome this issue is the implementation of an additional scattering layer into the device. A standard OLED is used to study the impact of such layer. This layer can either be...

Organic materials have been found to offer various, promising advantages
for photovoltaic (PV) devices like flexibility and the potential
of low-cost/large scale production. Hybrid devices combine these advantages
with the chemical/physical stability of inorganic materials
and, thus, overcome the issue of limited lifetimes of purely organic
cells. Poly(styrene-block-ethylene oxide)...

Organometal halide perovskites have been shown to be great candidates for photovoltaics, owing to the strong absorption, and high mobility and diffusion length of photo-generated charge carriers. Subsequently, solar cells employing perovskite thin films have reached efficiencies of more than 20%, making them comparable with commercially available silicon solar cells. The performance of...

Neutron Depth Profiling (NDP) is a non-destructive, near-surface analytical technique to selectively study the distribution of several light elements with high lateral and depth resolution [1]. Upon capture of a neutron, the investigated elements emit charged particles, which carry the depth information of the parent nuclei and are detected via surface barrier detectors. NDP offers a wide...

Multi-responsive polymers have gained a lot of attention, mainly due to the huge array of applications [1] they can be used for, such as sensors, drug delivery systems or tissue engineering. In this work, core-shell micelles with a pH-responsive shell, whose shell blocks undergo a phase transition from expanded to collapsed as a response to changes on the pH, are investigated. At higher...

The pretreatment of wood in ionic and complementary liquids is studied in and ex situ by small angle neutron scattering studies. We detect different stages of decomposition and connections to morphological stages. The general aim of the pretreatment is the accessibility of the cellulose to enzymatic scission of the chains such that valuable oligomers are obtained for further chemical reactions.
