Sputtering Mechanism of an Unsintered Organic–Inorganic Sputtering Target for Perovskite Solar Cells

Advanced Energy Materials, EarlyView.
An unsintered MAPbI3 sputtering target fabricated via a mechanochemical route enables large‐area vacuum deposition of perovskite absorber layers, while revealing an ion–photon coupled decomposition mechanism that governs target erosion and film composition under RF plasma exposure.

Kinetic Analysis of Transmetalation at Prototypical Nickel(II) Catalyst Species: Rates, Mechanisms, and Implications for Catalysis

Angewandte Chemie, EarlyView.
A 31P{1H} NMR method enabling direct measurement of transmetalation at Ni(II) is disclosed, providing an extensive kinetic dataset. Rates span five orders of magnitude and exhibit strong ligand dependence, with monodentate ligands promoting transmetalation.

Agricultural Diversification at the Margin. Strategies and Determinants in Italian Mountain and Remote Areas

Agribusiness, EarlyView.
ABSTRACT This paper explores the convergence in on‐farm diversification strategies of agricultural holdings, between remote areas and more central ones. Using Italian farm‐level data, we explore the determinants of diversification strategies across farms.

Beyond Simple Mimicry: Next‐Generation Geometric Architectures and Future Paradigms in Small‐Molecule and Macrocyclic Peptidomimetics

Angewandte Chemie, EarlyView.
Peptide‐to‐Small Molecule Paradigm: Peptidomimetics have evolved from simple mimicry toward drug‐like scaffolds supported by increasing clinical successes. This Perspective highlights the geometric design principles—linear repetition, convergent fusion, and cyclization—defining the next‐generation peptidomimetic architectures capable of targeting ...

The thermosphere at South Pole

The thermosphere at South Pole
P(論文) The Earth's thermosphere provides the first layer of atmosphere to filter the sun's optical radiation on its way to the surface. In addition, it absorbs most of the energetic particles swept up from interplanetary space and guided downwards along magnetic field lines.

Cteno‐Bot: An Untethered Metachronally Swimming Robot With Magnetoactive Propulsors

Advanced Intelligent Systems, EarlyView.
We present Cteno‐bot, an untethered ctenophore‐inspired robot which swims using metachronally coordinated appendages. A single mechanism controls up to 216 magnetoactive propulsors via a dynamically varying magnetic field. We show that the swimming speed of the robot can be increased without a corresponding increase in power requirement, simply by ...

Beyond the Fixed Charge: A New On‐Tissue Derivatisation Strategy Employing Photoionisable Chromophores for Mass Spectrometry Imaging of Amino‐Containing Metabolites

Angewandte Chemie, EarlyView.
We introduce a novel chemical derivatisation strategy for the UV‐activated detection of elusive metabolites. Incorporation of a tocopherol‐active chromophore allows for the detection of tagged analytes as photoionised radical cations, selectively induced by a 266 nm laser.
