Furan‐Substituted Phosphine‐Oxide as an Efficient Interfacial Modifier for Wide‐Bandgap Perovskite Solar Cells

open access: yesAdvanced Functional Materials, EarlyView.
We report phosphine‐oxide interlayers for wide‐bandgap perovskite solar cells, in which tuned P = O Lewis basicity enables selective passivation of buried NiOx/perovskite interfaces and introduces interfacial dipoles that strengthen the built‐in field.

Solvent‐Free Manufacturing of Multifunctional Gas Diffusion Electrode Architectures for Enhanced CO2 Conversion From Low‐Concentration Streams

open access: yesAdvanced Functional Materials, EarlyView.
A tandem gas diffusion electrode (GDE) leveraging hierarchically engineered microgranules enables efficient CO2 electroreduction under dilute CO2 conditions. A key innovation lies in the solvent‐free precision assembly of metal–organic‐frameworks, carbon nanotubes, and copper nanoparticles.

An oriented-design simplified model for the efficiency of a flat plate solar air collector [PDF]

open access: yes, 2010
In systems design, suitably adapted physical models are required. Different modelling approaches for a solar air collector were studied in this paper. First, a classical model was produced, based on a linearization of the conservation of energy equations.

Experimental and numerical investigations of free convection heat transfer in solar oven [PDF]

open access: yes, 2012
The use of solar energy for baking, heating or drying represents a sustainable way of solar energy applications with negligible negative effects. Solar oven is an alternative to conventional oven that rely heavily on coal and wood or Electric oven that

Plasmonic Enhancement of Fluorescence and Protein Dynamics in Living Mammalian Cells

open access: yesAdvanced Materials, EarlyView.
This study demonstrates plasmonic enhancement of the function of fluorescent voltage sensing proteins (genetically encoded voltage indicators, (GEVIs), QuasAr6) in live mammalian cells. Coupling to plasmonic nanoparticles does not just increase fluorescence, but influences the protein photocycle, creating a hybrid sensor with its response speed to ...
