Tannic acid is not mutagenic in germ cells but weakly genotoxic in somatic cells of Drosophila melanogaster [PDF]

open access: yes, 2017
Tannic acid (TA) was tested for genotoxic activity in three different assays (1-3) in Drosophila melanogaster by feeding of larvae or adult flies. TA did not induce sex-linked recessive lethals (1) nor sex-chromosome loss, mosaicism or non-disjunction (2)

Designing Scalable Mechano‐Virucidal Nanostructured Acrylic Surfaces for Enhanced Viral Inactivation

open access: yesAdvanced Science, EarlyView.
Can a surface be designed to physically break viruses? This study explores how nanoscale geometry—specifically the spacing of tiny pillars—can determine whether viruses remain intact or rupture. Using flexible acrylic and a scalable fabrication process, the authors develop nanopillared, transparent surfaces that show strong antiviral activity without ...

A Universal Metal–Flavonoid Coating Strategy: Engineering Biomaterials for Diabetic Bone Regeneration

open access: yesAdvanced Science, EarlyView.
Construction of metal–flavonoid functionalized coatings on conventional bone repair materials. A one‐pot method is used to directly construct multifunctional metal–flavonoid coatings on the surface of traditional bone repair materials by selecting metal ions with osteogenic/angiogenic properties and flavonoids with reactive oxygen species scavenging ...

Reprogrammable Hydroplastic Latex Films and Water‐Driven Phase Separation

open access: yesAdvanced Science, EarlyView.
Hydroplastic latex films with discontinuous hydrophobic phases surrounded by continuous hydrophilic phases, are prepared. Upon immersion in water, the latex films have water‐driven phase separation. ABSTRACT Thermoplastics are a class of plastic polymers that can be remolded repeatedly by heating and cooling.

Improved Direct Ink Writing of Liquid Metal Foams via Liquid Additives

open access: yesAdvanced Electronic Materials, EarlyView.
The ability to pattern liquid metal is useful for making soft electrical and thermal devices. Dispensing liquid metal from a nozzle naturally results in the formation of spheroidal droplets, making direct‐write printing challenging. Liquid metal foams containing pockets of air can extrude as filaments, albeit inconsistently.

Stage‐Specific Roles of Deep Eutectic Solvents in Recycling of Spent Lithium‐Ion Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Deep eutectic solvents (DESs) offer tunable acidity, redox, and coordination properties for selective recycling of spent lithium‐ion battery cathodes. Through co‐dissolution, single‐ and two‐metal separations, DESs enable sustainable recovery of critical metals for closed‐loop regeneration of battery‐grade materials, advancing a circular economy for ...
