Bio‐Based Transparent Self‐Healable Polyimides Enabled by Isosorbide‐Derived Dianhydride Design and Aliphatic Chain‐Mobility Regulation

open access: yesSmall, EarlyView.
Transparency, toughness, and self‐healing rarely coexist within a single polyimide. This bio‐based aliphatic–aromatic film resolves that conflict. An isosorbide‐derived dianhydride and a fatty diamine cooperatively suppress charge‐transfer complexes, yielding a colorless film that heals rapidly under mild heat, retains its toughness, and restores ...

Polypyrrole Nanofibrous Aerogel for Pressure Sensing and Anionic Contaminant Remediation

open access: yesSmall, EarlyView.
Nanofibrous aerogels (NFAs), highly porous ultralow‐density networks of entangled nanofibers, are conformally coated with polypyrrole (PPy) to provide a multifaceted material platform. Leveraging NFA's high surface area and mechanically robust structure with the conductive properties of PPy enables pressure‐responsive sensing for flexible electronics ...

Ultralow‐Loading Ir Single Atoms Ligated by Multiple Bimetal Selenides in Spindle Heterostructures Derived From Porous Ni─Fe Metal‐Organic Frameworks for Efficient and Durable H2 Production via Water Splitting

open access: yesSmall, EarlyView.
We report ultralow‐loading Ir single atoms ligated through multiple nickel selenide and iron selenide sites within porous spindle heterostructures (Ir‐NS/FS), derived from porous nickel–iron metal–organic frameworks through hydrothermal reconstruction followed by chemical vapor deposition of Ir and Se.

Wrinkling Pickering Emulsions via Endospore Germination

open access: yesSmall, EarlyView.
This study presents a method for creating Pickering emulsions with long shelf life using bacterial endospores as stabilizers. Upon exposure to favorable conditions, spores germinate, swelland trigger wrinkling on droplet surfaces. The resulting patterns depend on initial interfacial coverage, enabling the change of droplet morphology on demand.

Stimuli‐responsive nanostructured hydrogen sulfide donors for enhanced cancer treatments

open access: yesSmart Molecules, EarlyView.
Three typical kinds of stimuli‐responsive nanostructured hydrogen sulfide (H2S) donors are reviewed. The nanostructures ensure precise delivery of H2S to the lesion site and regulate the release behavior. The H2S‐based gas therapy has been used to synergize with other cancer treatment modalities, achieving enhanced efficacy while reducing side effects.

Investigation of the Reoxidation and Material Behavior of Directly Reduced Pellets and Fines Under Simulated Rail Transport Conditions

open access: yessteel research international, EarlyView.
The study investigates the reoxidation behavior of DRI pellets (Midrex and H2‐reduced) under realistic conditions, considering the test parameters of temperature, humidity, storage duration, particle size (including fine fraction), and container geometry. The samples are analyzed based on mass changes.
