Salt hydrates are promising candidates for the long-term thermochemical heat storage (TCES) in thebuilding environment. In such storage systems, the surplus of energy will be exploited in an endothermicreaction to dehydrate the salt hydrates. Once it is demanded, the stored energy will be released throughan exothermic reaction by hydrating the...

Potassium carbonate, K2CO3, has been identified as one of the most promising thermochemical storagematerials for the built environment. Where a lot of knowledge has been gained on hydration/dehydrationbehavior at atmospheric (open system) conditions, little is known of this process under pure water vaporconditions (closed vacuum system). In this...

Thermochemical energy storage (TCES) is an emerging technology promising for domestic applications. Recently, K2CO3 was identified and studied as a TCES material. In this work, the composite “K2CO3 in expanded vermiculite” (69 wt. % of the salt) was prepared and studied for thermochemical energy storage bearing in mind its application for space...

Water oxidation catalysis plays a pivotal role in the context of the worldwide interest for sustainable energy. Finding cost-effective and robust catalysts to replace the state-of-the-art noble metal materials is hence urgent. In this work, we develop a molecular iridium complex that selectively and uniformly anchors on the surface of manganese...

The visibility on New Year's nights in the Netherlands is low during stagnant weather. This is due to the scattering and absorption of light by the aerosol-smoke from the fireworks. We made an assessment of the responsible aerosol-species. The investigation took place during the New Year's night of 2009. Measurements were made at a regional site...

BACKGROUND: Epidemiological evidence on the association between ambient air pollution and breast cancer risk is inconsistent. OBJECTIVE: We examined the association between long-term exposure to ambient air pollution and incidence of postmenopausal breast cancer in European women. METHODS: In 15 cohorts from nine European countries, individual...

Previously we showed in the osjar1 mutants that the lodicule senescence which controls the closing of rice flowers was delayed. This resulted in florets staying open longer when compared with the wild type. The gene OsJAR1 is silenced in osjar1 mutants and is a key member of the jasmonic acid (JA) signaling pathway. We found that K...

Non-encapsulated CIGS solar cells with different contents of sodium (Na) and potassium (K) were simultaneously exposed to damp heat and illumination. The solar cells with higher alkali (Na, K) content exhibited higher initial conversion efficiencies, but degraded severely within 100 hours, while samples with a lower alkali content retained their...

Unencapsulated CIGS solar cells with high and low contents of sodium (Na) and potassium (K) were simultaneously exposed to damp heat and illumination. The solar cells with a high alkali (Na, K) content exhibited higher initial conversion efficiencies, but degraded severely within 100-h, while the alkali poor samples kept relatively stable...

Asymmetric flat-sheet membranes made of poly(vinyltrimethylsilane) (PVTMS) were studied for the regeneration of amine-based absorption solvents in a membrane gas-liquid contactor at 100°C. It was shown that PVTMS membrane possesses good mechanical and chemical stability in contact with 4 M monoethanolamine (MEA) and 2 M potassium taurate (PT)...

Trace and major elements concentrations in PM10 and PM2.5 were measured at 20 sites spread in the Barcelona metropolitan area (1 rural background, 6 urban background, 13 road traffic sites) and at 1 reference site. Three 2-week samples per site and size fraction were collected during 2009 using low volume samplers, adding a total of 120 samples....

Background:As sodium, potassium and fluid intake are related to hypertension, an established risk factor for renal cell cancer (RCC), they may be independent risk factors for RCC.Methods:The Netherlands Cohort Study (NLCS) with case-cohort design included 120 852 participants aged 55-69 years. At baseline, diet and lifestyle were assessed with...

BACKGROUND: Negative effects of long-term exposure to particulate matter (PM) on lung function have been shown repeatedly. Spatial differences in the composition and toxicity of PM may explain differences in observed effect sizes between studies. METHODS: We conducted a multicenter study in 5 European birth cohorts - BAMSE (Sweden), GINIplus and...

A major consideration for post-combustion CO2 capture is the adverse effect of the presence of SO2 on the absorption desorption process. The most common approach is to remove the SO2 from the flue gases in a flue gas desulfurization (FGD) unit prior the CO2 recovery process. This paper reports the experimental and modeling results of a new...

The need for sodium reduction in our diet is clear to consumers, dieticians and food manufacturers. As sodium concentration has a strengthening effect on gluten, sodium reduction decreases dough mixing tolerance, dough resistance and induces dough stickiness. In particular, the latter may cause problems in mechanical processing of dough. In...

Polarization curves are of paramount importance for the detection of toxic components in microbial fuel cell (MFC) based biosensors. In this study, polarization curves were made under non-toxic conditions and under toxic conditions after the addition of various concentrations of nickel, bentazon, sodiumdodecyl sulfate and potassium ferricyanide....

Insulin signaling in the central nervous system (CNS) is required for the inhibitory effect of insulin on glucose production. Our aim was to determine whether the CNS is also involved in the stimulatory effect of circulating insulin on the tissue-specific retention of fatty acid (FA) from plasma. In wild-type mice, hyperinsulinemic-euglycemic...

This work describes the conceptual design of a novel separation process for CO2 removal from flue gas based on precipitating solvents. The process here described (DECAB) is an enhanced CO2 absorption based on the Le Chatelier's principle, which states that reaction equilibrium can be shifted by removing one of the constituents in the reaction. A...

OBJECTIVE - Insulin inhibits endogenous glucose production (EGP) and stimulates glucose uptake in peripheral tissues. Hypothalamic insulin signaling is required for the inhibitory effects of insulin on EGP. We examined the contribution of central insulin signaling on circulating insulin-stimulated tissue-specific glucose uptake. RESEARCH DESIGN...
