The Space Within: How Architected Voids Promote Tissue Formation

open access: yesAdvanced Materials, Volume 38, Issue 7, 2 February 2026.
This review explores the role of void spaces in tissue engineering scaffolds and examines four key methods for introducing porosity into hydrogels at different scales. It discusses sacrificial templating, microgels, phase separation, and 3D printing, highlighting principles, advantages, and limitations. It also addresses emerging strategies integrating

Sustainable Structural Hot‐Melt Adhesives Enabled by Functionalized Crystalline Lamellae

open access: yesAdvanced Materials, Volume 38, Issue 8, 6 February 2026.
A high‐performance, recyclable hot‐melt adhesive is developed from renewable materials. It features functional crystalline lamellae that enhance shear strength and enable closed‐loop recycling. The adhesive also provides excellent water and oxygen barrier properties, meeting both sustainability and performance demands for advanced bonding and sealing ...

Electrically Tunable Friction: From Sticky to Slippery with Ionic Hydrogels

open access: yesAdvanced Materials, Volume 38, Issue 8, 6 February 2026.
This work demonstrates electrically tunable friction “from sticky to slippery” using ionic hydrogels, achieving reversible more‐than‐fifty‐fold modulation without liquid lubricants. An electric field extracts a salt‐rich interfacial layer that dramatically reduces friction.

N‐(Heptafluoroisopropylthio)saccharin as a Practical Reagent for Electrophilic –SCF(CF3)2 Installation

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 3, 3 February 2026.
A bench‐stable saccharin electrophilic reagent enables the direct installation of the heptafluoroisopropylthio group onto diverse (hetero)arenes and amines under mild conditions. The method forms CSRF and NSRF bonds in a single step and allows subsequent oxidation to sulfonamides.

Untargeted Metabolomics Reveals Seasonal and Tissue‐Specific Metabolic Shifts in Holothuria cinerascens

open access: yesChemistry &Biodiversity, Volume 23, Issue 2, February 2026.
Untargeted metabolic profiling of three body tissues from Holothuria cinerascens in South Africa using 1H‐NMR and UPLC–QTOF–MS revealed distinct tissue‐specific and seasonal metabolic variations, with the body wall and gut/mesentery exhibiting high metabolite diversity.
