Tracing the Dynamic Chemical Transformations of Spiro‐OMeTAD in Operating Perovskite Solar Cells

open access: yesAdvanced Science, EarlyView.
Mapping of Spiro‐OMeTAD layer's chemistry and electronic properties in PSC: Advanced cluster ion‐beam sputtering depth profile XPS reveals that environmental stressors (light, potential, and moisture) trigger the decomposition of LiTFSI dopants in Spiro‐OMeTAD.

Bidirectional Photoswitching of a Tailored Azobenzene with Red and Far‐Red Light Involving Triplet Sensitization in an Aqueous System

open access: yesAdvanced Science, EarlyView.
The action spectrum of a tailored azobenzene is shifted toward bio‐optical window through the chemical modification of its singlet and triplet energy levels. Consequently, the bidirectional photo‐switching of azobenzene in physiological conditions is achieved when excited by red and far‐red light, which offers greater tissue penetration.

Enhancing Atomic‐Resolution in Electron Microscopy: A Deep Learning Denoiser Operating in the Frequency Domain

open access: yesAdvanced Intelligent Systems, EarlyView.
The newly developed AI‐automated Fast Fourier Transform denoising algorithm surpasses conventional real‐space methods by revealing even light atoms otherwise hidden in noisy backgrounds. Atomic resolution electron microscopy has become an essential tool for many scientific fields, when direct visualization of atomic arrangements and defects is needed ...

A q-rious positivity

open access: yes, 2010
The $q$-binomial coefficients $\qbinom{n}{m}=\prod_{i=1}^m(1-q^{n-m+i})/(1-q^i)$, for integers $0\le m\le n$, are known to be polynomials with non-negative integer coefficients.

Biallelic Germline Inactivation of HROB Causes Primary Gonadal Insufficiency and is Potentially Associated with Colonic Polyposis Predisposition

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT The Homologous Recombination Factor With OB‐Fold (HROB) plays a role in homologous recombination and DNA replication, where it enhances the MCM8‐MCM9 helicase complex activity. Recent findings link biallelic germline HROB variants to primary gonadal insufficiency (hypergonadotropic hypogonadism), a phenotype also associated with MCM8/MCM9 ...
