Leading edge erosion (LEE) is one of the most critical degradation mechanisms that occur with wind turbine blades (WTBs), generally starting from the tip section of the blade. A detailed understanding of the LEE process and the impact on aerodynamic performance due to the damaged leading edge (LE) is required to select the most appropriate...

Knowledge on environmental plastic emission and spatial and temporal accumulation is vital for the development of successful mitigation strategies and risk assessments of plastics. In this study, emissions of both micro and macro plastic from the plastic value chain to the environment were assessed on a global level through a mass flow analysis ...

The degradation mechanisms of the molybdenum (Mo) back contact for Cu(In,Ga)Se2 solar cells in the presence of atmospheric species have been investigated. Mo/MoSe2 films on glass were immersed in water purged with the gases oxygen (O2), nitrogen (N2), carbon dioxide (CO2), air, in non-purged water, and exposed to air. It was found that the...

The degradation of photovoltaic (PV) systems is one of the key factors to address in order to reduce the cost of the electricity produced by increasing the operational lifetime of PV systems. To reduce the degradation, it is imperative to know the degradation and failure phenomena. This review article has been prepared to present an overview of...

In the case of an incident with nerve agents, the timely and ready detection and identification of such a substance on suspected surfaces is essential. However, the detection of low levels of nerve agents on a surface is a considerable challenge for conventional detection equipment, especially with VX, a highly toxic nerve agent with low...

The electrification of the transport industry is rapidly becoming a solution to mitigate the greenhouse emissions problem. However, this electrification faces multiple challenges related to higher operational cost and limited charging capacity. To cope with these challenges, within the European project URBANIZED, an optimization algorithm has...

Proprotein convertase subtilisin kexin type 9 (PCSK9) inhibits the clearance of low-density lipoprotein (LDL) cholesterol (LDL-C) from plasma by directly binding with the LDL receptor (LDLR) and sending the receptor for lysosomal degradation. As the interaction promotes elevated plasma LDL-C levels, and therefore a predisposition to...

CIGS (CuInGaSe2) solar cells are electronic devices that directly transform sunlight into electricity and fall into the category of thin film photovoltaic devices. Currently, this type of solar cell has reached the record in photovoltaic conversion efficiency of around 23.35%. However, the maturity of a PV technology also requires reliability...

An extensive post-mortem analysis was conducted on a commercial copper-(indiumgallium)-diselenide (CIGS) photovoltaic module that degraded after exposure to the high voltage stress of a standardized potential induced degradation (PID) test. We employed a custom-developed coring technique to extract samples from the full-size field module, which...

Novichoks are a novel class of nerve agents (also referred to as the A-series) that were employed in several poisonings over the last few years. This calls for the development of novel countermeasures that can be applied in protective concepts (e.g., protective clothing) or in decontamination methods. The Zr metal−organic framework MOF-808 has...

This paper describes mechanical degradation experiments carried out to simulate possible bending effects of flexible CIGS modules when mounted on flexible floaters on sea. In an offshore environment the PV modules are subjected to millions of deformations per year. It is concluded that the strain induced by the bending can lead to serious...

System voltages can cause significant degradation in photovoltaic modules. Polarization-type potential-induced degradation (PID) is accompanied by decreases in the short-circuit current density and the open-circuit voltage. The system voltage causes a polarization and surface charge accumulation, increasing the interface recombination. The...

After a 13,000-hour test campaign with aqueous 30 wt% MEA (2-aminoethanol) solvent at the CO2 capture pilot plant at Niederaussem, another long-term test was carried out as part of the ALING-CCUS project. This test ran for more than 12,275 hours with aqueous AMP/PZ (2-Amino-2-methyl-1-propanol/piperazine) solvent, named CESAR1 (3.0 molar AMP (~...

Oxide/metal/oxide (OMO) layer stacks are promising replacements for conventional transparent conductive oxides in thin-film photovoltaics. They can provide colouration of the solar cells by adjusting their thickness to optimised optical resonances. Green OMO multistacks were deposited on glass by subsequent sputtering of aluminium doped zinc...

An important surveillance task during naval military operations is early risk assessment of vessels. The potential risk that a vessel poses will depend on the vessel type, and vessel classification is therefore a basic technique in risk assessment. Although automatic identification by AIS is widely available, the AIS transponders can potentially...

This work aims to understand oxygen solubility in pure and aqueous amine solvents for CO2 capture. Commercially available dissolved oxygen sensors were studied to evaluate whether these can be used for measuring oxygen solubility in the carbon capture processes. It also aims to understand the possible discrepansies from realistic concentrations...

The performance of military tasks is often exacerbated by additional load carriage, leading to increased physical demand. Previous studies showed that load carriage may lead to increased risk of developing musculoskeletal injuries, a reduction in task speed and mobility, and overall performance degradation. However, these studies were limited to...
