Self‐Cooling Molecular Spin Qudits

open access: yesAdvanced Materials, EarlyView.
A material made of [GdEr] molecular dimers can encode a qudit and perform as a magnetic refrigerant. Microwave resonant pulses coherently manipulate its 16 spin states, while direct demagnetization measurements cool the material and a device down to temperatures below 1 K.

Polyimide‐Linked Hexaazatriphenylene‐Based Porous Organic Polymer with Multiple Redox‐Active Sites as a High‐Capacity Organic Cathode for Lithium‐Ion Batteries

open access: yesAdvanced Materials, EarlyView.
A high‐capacity polyimide‐linked porous organic polymer (HAT‐PTO) incorporating numerous redox‐active centers is synthesized via a hydrothermal reaction, delivering a high theoretical capacity of 484 mAh g−1. In situ hybridization with carboxyl‐functionalized multiwalled carbon nanotubes enhances conductivity and stability, achieving 397 mAh g−1 at C ...

Harnessing Self‐Sensitized Scintillation by Supramolecular Engineering of CsPbBr3 Nanocrystals in Dense Mesoporous Template Nanospheres

open access: yesAdvanced Materials, EarlyView.
Perovskite CsPbBr3 nanocrystals exhibit bright emission, fast response, and solution processability, but their nanoscale size limits efficient radiation detection. Organizing them into porous SiO2 mesospheres enhances radioluminescence up to 40 times, achieving an optimal combination of light yield, fast scintillation, and processability, providing a ...

Neoclassical vs Evolutionary Theories of Financial Constraints : Critique and Prospectus [PDF]

open access: yes
Complicated neoclassical models predict that if investment is sensitive to current financial performance, this is a sign that something is "wrong" and is to be regarded as a problem for policy.

Adaptive Twisting Metamaterials

open access: yesAdvanced Materials, EarlyView.
This work introduces torque‐controlled twisting metamaterials as a transformative platform for adaptive crashworthiness. By combining multiscale predictive modeling with experimental validation on additively manufactured gyroids, it demonstrates tunable stiffness, collapse stress, and energy absorption.

Advanced Porous Materials for Maritime Carbon Capture

open access: yesAdvanced Materials, EarlyView.
Carbon capture from emission sources, such as marine vessels, has attracted significant attention over the years. To achieve this goal, sorbents such as metal–organic frameworks (MOFs), porous polymer networks (PPNs), covalent organic frameworks (COFs), and their post‐synthetic modifications are currently being explored.
