Programming of Complex Magnetic Profiles Enforced by 4D Printed Magnetic LCE Actuators

open access: yesAdvanced Materials, Volume 38, Issue 51, 11 September 2026.
A 4D printing‐enabled magnetic programming strategy is introduced in which thermally actuated liquid crystal elastomers are magnetized in their target shape to encode complex three‐dimensional magnetic profiles. The resulting actuators achieve multistate shape morphing and programmable locomotion under low magnetic fields, without requiring specialized

Post mortem MRI of cholinergic white matter pathways across neurodegenerative diseases

open access: yesAlzheimer's &Dementia, Volume 22, Issue 9, September 2026.
Abstract INTRODUCTION Cholinergic white matter pathway (CWMP) degeneration is central in Alzheimer's disease (AD) and Lewy body disease (LBD). CWMP degeneration can be assessed in vivo using magnetic resonance imaging (MRI) proxies, but neuropathological validation is limited.

Tuning Fluorescence and Singlet Oxygen Generation in Heavy‐Atom‐Free BODIPYs Through Charge‐Transfer State Modulation

open access: yesChemistryEurope, Volume 4, Issue 9, September 2026.
Heavy‐atom‐free donor–acceptor BODIPYs reveal how boron substitution, core alkylation, and solvent polarity reshape the balance between locally excited and charge–transfer states. Singlet oxygen yields reach 75% when the charge–transfer state is accessible yet remains energetically close to the triplet manifold, establishing a practical design ...

On the Use of Dispersion Corrections by Default in Computational Catalysis

open access: yescScience, Volume 2, Issue 3, September 2026.
ABSTRACT Accurate adsorption energy predictions are central in computational catalysis. The need for higher accuracy without prohibitive computational costs has led to the development of correction schemes for density functional theory (DFT) predictions.

Toward Safer and Sustainable Lithium Metal Batteries: Fluorine‐Free Solid Polymer Electrolytes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 5, September 2026.
An analysis to assess the impact of fluorine in polymer electrolyte‐based lithium metal batteries has been conducted. It has been demonstrated that fluorine‐free LiTIM salt delivers a electrochemical performance similar to that of its fluorinated analogue salts, given the complete lithium dissociation in coordination with PEO and the restricted anion ...
