Unsaturated biobased polyesters from bicyclic α‐pinene‐based diols

open access: yesPolymer International, EarlyView.
We present the synthesis of four biosourced unsaturated polyesters made from chiral terpene‐based diols and esters of renewable diacids. The resulting materials harbor a bicyclic pinene ring in their backbones which leads to enhanced thermal properties while still conferring susceptibility to enzyme hydrolysis for chains having a cis alkene.

Bio‐Inspired Mesoporous Solar Evaporator Enabled by Upcycled PET

open access: yesSmall, EarlyView.
Upcycled PET waste is converted into graphite‐containing porous foam for compound‐eye‐inspired solar evaporation. The resulting three‐dimensional evaporator combines a moldable porous framework with a hemispherical multi‐surface architecture, enabling angle‐insensitive solar exposure, capillary water transport, and efficient freshwater production under

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Self‐Powered Broadband High‐Responsivity Photodetectors: p‐(CuS)x(ZnSe)1−x/p‐Si Isotype Heterojunction

open access: yesSmall, EarlyView.
This study reports a self‐powered broadband photodetector based on compositionally tuned p‐(CuS)x(ZnSe)1−x/p‐Si isotype heterojunctions. Increasing the CuS ratio improved the film crystallinity and produced a denser, more homogeneous nanopillar morphology, enhancing light absorption.

A Hodge–Tate decomposition with rigid analytic coefficients

open access: yesForum of Mathematics, Sigma
Let X be a smooth proper rigid analytic space over a complete algebraically closed field extension K of $\mathbb {Q}_p$ . We establish a Hodge–Tate decomposition for X with G-coefficients, where G is any commutative locally p-divisible rigid group.

Unlocking n‐alk‐1‐ynes conformers: Quantum “trigger finger” versus “stiff joint” conformations

open access: yesSmart Molecules, EarlyView.
Quantum chemical analysis reveals the unique function of n‐alk‐1‐yne terminus as a Quantum “Trigger Finger,” exhibiting two near‐isoenergetic conformers (Cs ${\mathrm{C}}_{s}$and C1 ${\mathrm{C}}_{1}$) locked by a symmetric high barrier. This contrasts with the lower asymmetric barrier of the conventional asymmetric “Stiff Joint” alkyl chain.

Some remarks on the companions conjecture for normal varieties

open access: yesComptes Rendus. Mathématique
Drinfeld in 2010 proved the companions conjecture for smooth varieties over a finite field, generalizing L. Lafforgue’s result for smooth curves. We study the obstruction to prove the conjecture for arbitrary normal varieties.

The Influence of the Pretreatment of Tool Steel on the Running‐In Phase of Diamond‐Like Carbon Coatings

open access: yessteel research international, EarlyView.
The influence of tool steel pretreatment on the running‐in behavior of TiNb‐diamond‐like carbon (DLC) coatings is investigated. Ion etching promotes carbide protrusion and increases coating roughness, while post‐deposition polishing reduces surface asperities.

Formation of Distance‐Based Orientation: Political Identity through Relational Positioning in Israel

open access: yesSymbolic Interaction, EarlyView.
Distance‐based orientation describes how pejorative labels may serve as anchor points for political identity. Existing research on political labeling has largely emphasized stigmatization, overlooking how labels may acquire durability and orienting capacity without losing pejorative force. Drawing on publicly circulating discourse, we trace positioning
