MAPbBr perovskite solar cells a two-step deposition process.

Organometal halide perovskite solar cells are becoming one of the most competitive emerging technologies. They have reached a power conversion efficiency (PCE) of 22.7% in 10 years.

[Erythermalgia and type 1 diabetes: diagnosis and management issues. A case report].

Erythermalgia is a very rare acrosyndrome mainly characterized by lower limbs pain. It is either primitive or secondary. Concomittence of erythermalgia and diabetes is a coincidence and since the latter induces neuropathic and vascular lesions, erythermalgia is then considered as a consequence.

Thermal desorption mass spectrometer for mass metrology.

This article presents a device for the study of physisorbed elements on polished surfaces (diameter ⩽56 mm) of the kind used in mass metrology. The technique is based on mass spectrometry of molecules desorbed after heating under vacuum of the analyzed surface. We describe a first application of the device to study current and future mass standards in order to understand how their surface reactivity depends on storage conditions, cleaning processes, and polishing methods.

Compound heterozygosity for dominant and recessive GJB2 mutations in a Tunisian family and association with successful cochlear implant outcome.

Objectives: Mutations of GJB2 encoding connexin 26 are the most common cause of hearing loss. They are responsible for up to 50% of ARNSHL. The pathogenic mutations in this gene are generally inherited recessively.

Apparatus to measure adsorption of condensable solvents on technical surfaces by photothermal deflection.

This article describes an instrument for the measurement of the mirage effect as a tool to determine the molar adsorption per unit surface area Y(1) of condensable solvents in the presence of a non-condensable carrier gas. The present apparatus is a much improved version of previous prototypes developed in our laboratory and elsewhere with a higher surface bake-out temperature (150 °C rather than 40 °C), lower residual vacuum (3 Pa versus 100 Pa), greater sample surface (40 mm diameter instead of 10 mm), more powerful optical pump beam (150 W cf. 50 W), and larger saturated vapour preparation volume (4 L instead of 1 L).

Linkage disequilibrium in inbred North African families allows fine genetic and physical mapping of triple A syndrome.

Triple A syndrome (Allgrove syndrome, MIM No. 231550) is a rare autosomal recessive disorder characterised by ACTH-resistant adrenal insufficiency, achalasia of the cardia, and alacrimia. The triple A gene has been previously mapped to chromosome 12q13 in a maximum interval of 6 cM between loci D12S1629 and D12S312.
