Stabilized Intermediate Phase Via Pseudo‐Halide Anions Toward Highly Efficient and Light‐Soaking Stable Perovskite Solar Cells

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
The formate pseudo‐halide anion is strategically introduced at the buried interface to stabilize the intermediate phases formed during perovskite crystallization. The controlled crystallization enhances crystallinity and alleviates tensile strain, eliminating residual PbI2 near the buried interface.

Changement climatique et conflits de genre dans l’agriculture paysanne dans l’Ouest Cameroun : cas de Batcham

open access: yesVertigO, 2017
In the Batcham subdivision family farms are ruled by a former land tenure that organizes the relationship of household members to the land. This reduces conflicts to a minimum threshold.

Climate Change Sceptics [PDF]

open access: yesEuropean Review, 2013
By predicting a global change of the Earth's climate, scientists are delivering an uncomfortable message. The release of the fourth IPCC report in 2007 has led to a surge of scepticism and criticism of both the science and the scientists. All this has received a lot of press coverage. Here I discuss the roots of climate change scepticism and how it has

Photo‐Assisted Zn‐Iodine Battery via Bifunctional Cathode with Iodine Host and Solar Response Boost

open access: yesAdvanced Functional Materials, EarlyView.
A bifunctional cathode based on BiOI materials is developed for photo‐assisted Zn‐iodine batteries, serving as both an iodine host and a solar‐responsive material. This design enables dual reaction routes involving vacancy‐based iodine storage and reversible two steps iodine redox.

Engineering the Hierarchical Porosity of Granular Hydrogel Scaffolds Using Porous Microgels to Improve Cell Recruitment and Tissue Integration

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
By fabricating and covalently assembling gelatin methacryloyl (GelMA) porous microgels, a new class of granular hydrogel scaffolds with hierarchical porosity is developed. These scaffolds have a significantly higher void fraction than their counterparts made up of nonporous microgels, enhancing cell recruitment and tissue integration. This research may
