Solution‐Processable, Ladder‐Branched Polyimides of Intrinsic Microporosity by [4+4] Cycloaddition for Membrane Gas Separation

open access: yesAdvanced Materials, Volume 38, Issue 4, 16 January 2026.
An effective post‐synthetic modification strategy utilizing [4+4] cycloaddition is demonstrated to fabricate ladder‐branched polyimides of intrinsic microporosity (PIM‐PIs) with significantly enhanced performance characteristics for membrane‐based gas separation.

Speech Recognition with Cochlea‐Inspired In‐Sensor Computing

open access: yesAdvanced Intelligent Systems, Volume 8, Issue 1, January 2026.
Traditional speech recognition methods rely on software‐based feature extraction that introduces latency and high energy costs, making them unsuitable for low‐power devices. A proof‐of‐concept demonstration is provided of a bioinspired tonotopic sensor for speech recognition that mimics the human cochlea, using a spiral‐shaped elastic metamaterial. The

Polyethylene Shows No Concerning Evidence of Material Changes or Stress Cracking After Exposure to Chlorhexidine Gluconate and Povidone‐Iodine Irrigation Solutions

open access: yesJournal of Orthopaedic Research, Volume 44, Issue 1, January 2026.
ABSTRACT Chlorhexidine‐gluconate (CHG) and povidone‐iodine (PI) are used as irrigation solutions to prevent infection in arthroplasty. This study to aimed to determine whether exposing ultra‐high molecular weight polyethylene (UHMWPE) implants to different concentrations of CHG or PI solutions would result in material or mechanical changes.
