Upscaling Perovskite Photovoltaics: from 156 cm2 Modules to 0.73 M2 Panels

Advanced Science, EarlyView.
From lab to sunlight: perovskite photovoltaics are scaled from 156 cm² large area modules to 0.73 m² panels. With 17.68% efficiency at module level and a stron 12% PCE in outdoor conditions, this advance represents a significant step toward real‐world deployment, paving the way from innovation to practical application.

Is Nature Generic? [PDF]

Lect.Notes Phys. 592 (2002) 3-15, 2001
An introductory guide to mathematical cosmology is given focusing on the issue of the genericity of various important results which have been obtained during the last thirty or so years. Some of the unsolved problems along with certain new and potentially powerful methods which may be used for future progress are also given from a unified perspective.

Antibacterial Properties of 3 H-Spiro[1-benzofuran-2,1’-cyclohexane] Derivatives from Heliotropium filifolium

Molecules, 2008
A re-examination of cuticular components of Heliotropium filifolium allowed the isolation of four new compounds: 3’-hydroxy-2’,2’,6’-trimethyl-3H-spiro[1-benzo-furan-2,1’-cyclohexane]-5-carboxylic acid(2), methyl 3†...

Ligand‐Dependent Chemoselectivity in Gold‐Catalyzed Reactions between Anthranils and Diynamides. Formation of Spiro Azacyclic Compounds versus 1‐Imino‐1H‐Indene‐3‐Carboximidamides

ChemistryEurope, EarlyView.
Gold catalysts direct anthranil/diynamide reactions: PPh3AuCl/AgNTf2 forms spiro azacycles (indole intermediate confirmed), while P(t‐Bu)2(o‐biphenyl)AuCl/AgNTf2 yields indene carboximidamides via a proposed mechanism. Gold‐catalyzed reactions between anthranils and diynamides have been investigated, and their reaction chemoselectivity relies on the ...

Glucose-derived spiro-isoxazolines are anti-hyperglycemic agents against type 2 diabetes through glycogen phosphorylase inhibition [PDF]

, 2016
International audienceGlycogen phosphorylase (GP) is a target for the treatment of hyperglycaemia in the context of type 2 diabetes. This enzyme is responsible for the depolymerization of glycogen into glucose thereby affecting the levels of glucose in ...

Enhancement of Optical Transparency and Electrical Conductivity of IZO/Ag/IZO Multilayer Film by Intense Pulsed Light and its Effect on the Photovoltaic Performances of Perovskite Solar Cells

Advanced Science, EarlyView.
The highly conductive IZO/Ag/IZO multilayer transparent electrode is successfully fabricated through flashlight annealing (FLA) process. A transient thermal effect of FLA maintains the continuous Ag interlayer and improves the crystallinity of the sandwich IZO layers. This combination increases both electric conductivity and optical transmittance.

Stereoselective Transformation of Cyclodecene-1,4-dione Systems, Derived from Steroids, to the Corresponding spiro-γ-lactones. A Semiempirical MO Study

Molecules, 1999
The thermal and acid-catalyzed intramolecular rearrangement of the (Z)- and (E)-cyclodecene-1,4-dione compounds deriving from steroids, 2a,b and 3a,b, respectively, proceeds stereoselectively to give the corresponding configurationally different spiro ...
