Turning Readily Available Acrylates into Cyclic Xanthates for Radical Ring-Opening Polymerizations
Abstract Cyclic sulfur-containing monomers represent a promising class of comonomers for radical ring-opening polymerization, but only a limited number of examples have been reported to date. Here, the cyclic xanthate tert-butyl 2-thioxo-1,3-oxathiolane-5-carboxylate (Oxa) was sy...

Kinetic Monte Carlo (kMC) simulations are fundamental for modeling atomistic surface morphology evolution, but their inherently sequential execution of atomic steps creates severe computational bottlenecks. This computational burden restricts accessible time-and length scales, ma...

Single-step decreases in the three-row Chomp diagonal sequence: A uniform bound below one half
Let dn be the unique first-row length for which (dn, n, n) is a losing position in three-row Chomp, and let gn = max{0, dn − dn+1}. For every integer n ≥ 6, we prove gn ≤ 83n/168 and the signed bound dn − dn+1 ≤ 83n/168 − 125/84. More precisely, the signed upper bound is 83n/168...

Near-rectangular P-positions in three-row Chomp with deficit at most six
We classify the losing positions (n,n,n-g) in three-row Chomp for every integer n>g and 1<=g<=6. There are exactly eight such positions. The proof combines a counting bound for the row at which a value becomes constant with a uniform bound obtained from Zeilberger's published low...

Carbonic Acid (H2CO3) Decomposes to Its Monohydrate (H2CO3·H2O) and CO2 on Decompression
Abstract The presence of H2O and CO2 on the icy moons in our solar system and in potentially habitable water worlds makes the understanding of phase stabilities and structure–property relations of phases in the H2O–CO2 system highly relevant for astrophysical research. Here we sh...

Palaearctic grasslands are among the most species-rich ecosystems of the Northern Hemisphere, but their conservation depends on continued management that must be reconciled with agricultural production, rural livelihoods and other socio-economic demands. Introducing a special iss...

A Computer-Assisted Proof of a First-Player Win in Infinite Freestyle Gomoku
We present a computer-assisted proof that the first player wins freestyle Gomoku on the infinite integer lattice. Players alternately occupy an empty lattice point, and a consecutive run of at least five stones in any of four directions wins immediately; neither player has forbid...

Accelerating Identification of Relevant Polarons in Batteries
Abstract Many of the materials under consideration as battery electrodes are known to exhibit polarons─charge carriers localized through polarizing their environments, which are unfortunately quite costly to tackle by theory. Next to costly ab initio methods and geometry optimiza...

Amid widespread biodiversity loss and alarming rates of tropical deforestation, the potential of secondary forest succession in restoring β-diversity is still widely unexplored. To investigate β-diversity along naturally recovering forests, we collected the functionally diverse g...

Afghanite: A New Silicate‐Matrix Reference Material for In Situ Halogen and Sulfur Microanalysis
Sulfur (S) and the halogens (F, Cl, Br, I) play key roles in geochemical processes that govern volatile cycling, redox evolution, phase reactions and ore formation in the Earth's crust and mantle. Quantifying these elements in situ requires well‐characterised reference materials...

Abstract The production of hydrogen via acidic water electrolysis requires efficient oxygen evolution reaction (OER) at high current densities. However, this is often limited by oxygen bubble accumulation, which blocks active sites and restricts water access. Although bubble rele...

Community assembly on inland cliffs is context‐dependent
Abstract Under harsh environmental conditions, community assembly processes are expected to drive pronounced functional convergence, with communities dominated by stress‐tolerant species. Integrating local communities with their regional species pools enables evaluating environme...

Abstract The intensity of environmental stressors increases due to global change. Under natural conditions, insect pollinators are experiencing multiple stressors simultaneously which may exacerbate the negative effects of individual stressors. Using a fully crossed factorial des...

ABSTRACT In this study, Fe or Ni‐anchored silicon carbo(xy)nitride (SiCN(O)) fibre mats were synthesized via the polymer‐derived ceramics (PDC) approach to investigate their electrocatalytic performance toward alkaline OER. The resulting fibrous‐supported pre‐catalysts formed por...

Critical raw materials underpin the energy transition, defense, and digitalization, yet criticality assessments remain diagnostic: they quantify supply risk and vulnerability without prescribing how to act. This gap is addressed through a structured review, from which 139 mitigat...

Abstract Pollinators like bumblebees are exposed to microplastics (MP) pollution during foraging. After returning to the colony foragers may subsequently spread MP in the nest or transfer ingested MP to larvae during cooperative brood care. Experimental studies have shown that MP...
