Crystallization of Small Molecules in Microgravity Using Pharmaceutical In-Space Laboratory–Biocrystal Optimization eXperiment (PIL-BOX)

open access: yesCrystals
Crystallization in microgravity has measurable benefits, from molecules as simple as sodium chloride to elaborate protein complexes. However, small organic molecules have not been reported.

Separating Hydrogen Evolution From Electroplating in Zn Metal Batteries Using Scanning Electrochemical Microscopy

open access: yesAdvanced Energy Materials, EarlyView.
Operando SECM decouples hydrogen evolution from other degradation pathways in Zn metal batteries by quantifying its contribution during Zn electrodeposition. Although HER is shown to account for only a minor fraction of the irreversible charge loss, it remains a key indicator of interfacial evolution and by‐product formation governing cycling ...

Site Density Governs Switching Reactivity Regimes During Aerobic C─H Oxidation in Mn Single‐Atom Photocatalysts

open access: yesAngewandte Chemie, EarlyView.
Increasing the density of isolated manganese (Mn) atoms in carbon nitride (CNx) photocatalysts does not continuously improve performance. Instead, beyond a critical loading, the polymer support reorganizes, altering charge‐carrier dynamics and oxygen activation while preserving atomic dispersion.

Covalently Locked Donor–Acceptor Block Copolymer Nanoparticles Enable Efficient, Stable and Reproducible Photocatalytic Hydrogen Evolution

open access: yesAdvanced Energy Materials, EarlyView.
To overcome the efficiency–stability trade‐off of traditional donor:acceptor blends, covalently locked all‐conjugated block copolymer nanoparticles are developed for solar hydrogen production. This strategy achieves an outstanding HER rate exceeding 120 mmol cm−2 g−1 h−1, alongside exceptional operational stability (95% retention after 96 h) and high ...

RNA Organelles in DNA‐Based Artificial Cells Provide Spatial Aptamer Functions and Enhanced Signal Processing

open access: yesAngewandte Chemie, EarlyView.
Multiphase DNA–RNA artificial cells integrate a protective DNA shell, a transcriptionally active DNA core, and a functional RNA organelle. Spatial compartmentalization enables signal generation, external protein expression, and selective recapture via RNA aptamers. ABSTRACT Naturally occurring biomolecular condensates orchestrate key cellular processes

Agronomic and Nutritional Perspectives on Vegetable Crops in Africa

open access: yesAgriFood: Journal of Agricultural Products for Food, EarlyView.
Vegetable production plays a key role in food security, nutrition, and livelihoods across Africa. Moreover, African indigenous vegetables emerge as underutilized yet highly valuable crops, rich in macro‐ and micronutrients, as well as bioactive compounds with an array of health benefits.

Elucidating Liquid‐Phase Guest Transport Across MOF Single Crystals: Interplay of Adsorption, Desorption, and Intracrystalline Diffusion

open access: yesAngewandte Chemie, EarlyView.
Guest transport across metal–organic framework (MOF) single crystals disentangles transport occurring through the micropores from contributions at grain boundaries. Even guest molecules with identical kinetic diameters show drastically different transport behavior arising from the distinct modes of adsorption. Neither pore clogging nor surface collapse

Roi cherché, roi montré, roi transfiguré

open access: yesCalenda, 2009
Dans le cadre de l’exposition « Fêtes et crimes à la Renaissance : la cour d’Henri III » présentée au château royal de Blois de mai à août 2010 et consacrée à un souverain soucieux de consolider son pouvoir par la mise en scène du corps monarchique, nous nous proposons de questionner l’élaboration de la représentation du corps du prince, sa diffusion ...

Real‐Time Multicolor Fluorescence Microscopy via Cross‐Channel Acquisition and Deep‐Learning‐Based Inference

open access: yesAdvanced Intelligent Discovery, EarlyView.
Sequential multicolor fluorescence imaging in dynamic microsystems is constrained by acquisition speed and excitation dose. This study introduces a real‐time framework to reconstruct spectrally separated channels from reduced cross‐channel acquisitions (frames containing mixed spectral contributions).
