Biodeterioration affecting efficiency and lifetime of plastic-based photovoltaics
(2020-09-16)The low environmental impact of electricity generation using solar cells crucially depends on high energy-conversion efficiencies, long lifetimes and a minimal energy and material demand during production. Emerging thin-film ... -
Renewable Energy from Finite Resources: Example of Emerging Photovoltaics
(2020)Renewable energies, such as sunlight, wind and geothermal heat, are resources that are replaced rapidly by natural processes. However, wind, hydro and solar installations strictly require raw materials that are, in fact, ... -
Renewable Energy from Finite Resources: Example of Emerging Photovoltaics.
(2019-11-01)Renewable energies, such as sunlight, wind and geothermal heat, are resources that are replaced rapidly by natural processes. However, wind, hydro and solar installations strictly require raw materials that are, in fact, ... -
Environmental glucocorticoids corticosterone, betamethasone and flumethasone induce more potent physiological than transcriptional effects in zebrafish embryos.
(2019-07-01)Many glucocorticoids occur in the aquatic environments but their adverse effects to fish are poorly known. Here we investigate effects of the natural glucocorticoid corticosterone and the synthetic glucocorticoids betamethasone ... -
Improved phosphoric acid recovery from sewage sludge ash using layer-by-layer modified membranes
(2019-10-01)We report an advanced treatment method for phosphoric acid recovery from leached sewage sludge ash. Layer-by-layer (LbL) polyelectrolyte deposition has been used as a tool to modify and convert a hollow ultrafiltration ... -
Phosphorus recovery in an acidic environment using layer-by-layer modified membranes
(2019-07-15)Phosphorus (P) is a limited natural resource and essential for global food supply, particularly given our ever-growing world population. However, natural P deposits are restricted to just a few countries and the quality ... -
Glucocorticoid mixtures of fluticasone propionate, triamcinolone acetonide and clobetasol propionate induce additive effects in zebrafish embryos
(2019-07-15)Many synthetic glucocorticoids from medical applications occur in the aquatic environment. Whether they pose a risk for fish health is poorly known. Here we investigate effects of glucocorticoids fluticasone propionate ... -
Fungicides chlorothanolin, azoxystrobin and folpet induce transcriptional alterations in genes encoding enzymes involved in oxidative phosphorylation and metabolism in honey bees (Apis mellifera) at sublethal concentrations.
(2019-09-05)Fungicides are highly used for plant protection but their molecular and chronic effects are poorly known. Here, we analyse transcriptional effects in the brain of honey bees of three frequently applied fungicides, azoxystrobin, ... -
A VITELLOGENIN ANTIBODY IN HONEY BEES (APIS MELLIFERA) Characterization and application as potential biomarker for insecticide exposure: Vitellogenin as potential biomarker for insecticide exposure
(2019-02)The insect yolk precursor vitellogenin is a lipoglycoprotein synthesized and stored in the fat body and secreted into the hemolymph. In honey bees, vitellogenin displays crucial functions in hormone signaling, behavioral ... -
Mixtures of Aluminum and Indium Induce More than Additive Phenotypic and Toxicogenomic Responses in Daphnia magna.
(2019-01)Aquatic systems are contaminated by many metals but their effects as mixtures on organisms are not well understood. Here, we assessed effects of aluminum with fairly well-known modes of actions and indium, an understudied ... -
Potential for water reuse in Vietnam
(2018)Southeast Asian countries and Vietnam in particular are facing water security challenges; water reclamation is increasingly being considered as a favorable solution. Despite the availability of suitable technologies, several ... -
Anaerobic digestion of biowastes in India: Opportunities, challenges and research needs
(2019-04-15)The quest for improved living conditions in rapidly growing Indian communities puts pressure on natural resources and produces emissions which harm the environment, society and the economy. Current municipal solid waste ... -
Continuous flow adsorption of phenolic compounds from olive mill wastewater with resin XAD16N: life cycle assessment, cost–benefit analysis and process optimization
(2019)Olive mill wastewaters (OMWs) represent a major environmental concern due to their high organic loadand phytotoxic activity. The selective recovery of phenolic compounds (PCs) from OMW is promising, thanks to the antioxidantand ... -
Layer-by-layer membrane modification allows scandium recovery by nanofiltration
(2019-07)Aluminium scandium (Sc) alloys are stronger, more corrosion resistant and more heat tolerant than classical aluminium alloys and allow for 3D printing. In particular, the aerospace industry benefits from better fuel efficiency ...
