Phase‐Pure and Size‐Tunable Tin Halide Perovskite Quantum Dots

Advanced Materials, EarlyView.
A trioctylphosphine oxide modulated protocol allows for the synthesis and study of the optical properties of a broad library of tin halide perovskite quantum dots across multiple A‐ and X‐site compositions with precise size tuning while eliminating unwanted 2D phases.

Rethinking Charge Transport and Recombination in Donor‐Diluted Organic Solar Cells

Advanced Materials, EarlyView.
Organic solar cells with 1–45% PM6 content in Y12 were studied to link structure and charge dynamics to performance. The conductivity follows a 3D percolation model without a sharp threshold. Donor dilution preserves the photogeneration yield, but limits the fill factor due to transport resistance losses.

Gene trapping identifies transiently induced survival genes during programmed cell death

, 2001
Background: The existence of a constitutively expressed machinery for death in individual cells has led to the notion that survival factors repress this machinery and, if such factors are unavailable, cells die by default.

Xer-mediated site-specific recombination in vitro

, 1996
The Xer site-specific recombination system acts at ColE1 cer and pSC101 psi sites to ensure that these plasmids are in a monomeric state prior to cell division.

Function of bacteriophage orf recombinasesin genetic exchange [PDF]

, 2006
Recombination events in bacteriophages frequently occur by illegitimate exchange at short tracts of sequence homology, enabling these viruses to acquire novel genes and serve as vehicles for horizontal gene transfer.

Control of directionality in bacteriophage mv4 site-specific recombination: functional analysis of the Xis factor.

, 2010
International audienceThe integrase of the temperate bacteriophage mv4 catalyzes site-specific recombination between the phage attP site and the host attB site during Lactobacillus delbrueckii lysogenization.

Designable van der Waals Crystal for Artificial Neuronal Cell Mimicking

Advanced Materials, EarlyView.
Designable van der Waals crystal has been demonstrated for device‐scale neuronal cell mimicking. The structural similarity between ion‐channel in biological membranes and layered vdW lattices is realized with nano‐crystallization via Ar + H2S plasma sulfurization.

Variable orthogonality of serine integrase interactions within the ϕC31 family

Scientific Reports
Serine integrases are phage- (or mobile element-) encoded enzymes that catalyse site-specific recombination reactions between a short DNA sequence on the phage genome (attP) and a corresponding host genome sequence (attB), thereby integrating the phage ...

Ultra‐High‐Throughput Discovery of Multifunctional Polyphenolic Coatings on Droplet Microarrays

Advanced Materials, EarlyView.
An ultra‐high‐throughput (UHT) combinatorial strategy enables the miniaturized synthesis and screening of ≈30 000 polyamine‐polyphenolic (PaPp) coatings using droplet microarrays (DMA). This approach reveals hundreds of previously unknown fluorescent, redox‐active, and antibacterial materials, including multifunctional, cell‐compatible surfaces ...
