Inhalation exposure during spray application and subsequent sanding of a wood sealant containing zinc oxide nanoparticles.

Nano-enabled construction products have entered into commerce. There are concerns about the safety of manufactured nanomaterials, and exposure assessments are needed for a more complete understanding of risk. This study assessed potential inhalation exposure to ZnO nanoparticles during spray application and power sanding of a commercially available wood sealant and evaluated the effectiveness of local exhaust ventilation in reducing exposure.

[Ischemic stroke: the cardiac workup].

The cardiac workup of stroke often includes a 24 hours Holter and an echocardiography looking for cardiac sources of emboli (atrial fibrillation (AF), intracardiac thrombus, mitral stenosis, recent myocardial infarction, endocarditis, dilated cardiomyopathy...

Doping of polycrystalline CdTe for high-efficiency solar cells on flexible metal foil.

Roll-to-roll manufacturing of CdTe solar cells on flexible metal foil substrates is one of the most attractive options for low-cost photovoltaic module production. However, various efforts to grow CdTe solar cells on metal foil have resulted in low efficiencies. This is caused by the fact that the conventional device structure must be inverted, which imposes severe restrictions on device processing and consequently limits the electronic quality of the CdTe layer.
