VIP: Two-Color RESOLFT Nanoscopy with Green and Red Fluorescent Photochromic Proteins

Dual-color live-cell RESOLFT superresolution microscopy is demonstrated with green- and red-emitting switchable fluorescent protein tags. The red-emitting tag is a novel reversibly switchable protein, rsCherryRev1.4, enabling a resolution up to four times over the diffraction barrier. Dual-color RESOLFT works with both single and multiple ‘donuts’ using more than 23000 ‘donuts’ in parallel.

Shred the gap: To achieve a highly efficient ZnO-based photocatalyst for hydrogen production by photo-electrochemical water splitting, ZnO is co-doped with compensated and noncompensated n–p pairs. This results in narrowed band-gaps, reduced electron–hole recombination centers, suitable band-edge positions, enhanced optical absorption, and good stability, by comparison with undoped ZnO.

In situ cell concept: A review of the state of the art of dye solar cells (DSCs) evidences a broadening range of new and fundamental topics, such as novel organic dyes and perovskites. An in situ cell-manufacturing concept (see picture) that can be applied to mesoscopic-based solar cells in general is proposed. Recent results from studies on large-area, glass-frit-sealed DSC modules are reported.

A square peg into a round hole? Contactless photoconductivity studies of poly(3-n-hexylthiophene):acceptor bulk heterojunctions indicate that a spherical acceptor shuttles electrons out of the mixed phase. In contrast, a planar acceptor forms a glassy mixed phase, characterized by strong interactions between the donor and acceptor, which results in poor electronic coupling between acceptor molecules, hindered electron transport, and enhanced carrier recombination.
