Biomass DNA: An Emerging Building Block for Advanced Materials

open access: yesAdvanced Materials, EarlyView.
Biomass DNA is rapidly emerging from its traditional role as a genetic blueprint to serve as a versatile abundant, highly programmable polymeric building block. This review highlights the transformation of macroscopic bulk biomass DNA into next generation of functional materials, spanning from dynamic hydrogels, sustainable bioplastics, and high ...

Vitamin C‐Induced Photo‐Redox Threshold Enables High‐Fidelity Volumetric Printing of Collagen

open access: yesAdvanced Materials, EarlyView.
Tomographic volumetric printing (TVP) of native proteins is limited by uncontrolled background crosslinking. Here, vitamin C is introduced as a biocompatible redox regulator to establish a tunable nonlinear polymerization threshold response for TVP.

Synthesis of Ti2B2Clx MBenes in Molten Salts From Theoretical and Experimental Perspectives

open access: yesAdvanced Materials, EarlyView.
By integrating a theoretical framework with experiments, Ti2InB2 was selectively etched with ZnCl2 to produce a multilayer (ml) Ti2B2Clx MBene. The In atoms are completely removed, with simultaneous incorporation of chlorine surface terminations. in situ x‐ray diffraction indicates a direct biphasic transformation from Ti2InB2 to ml‐MBene, with no ...

Mechanically‐Driven Reconstruction of Lithium Metal for Stable All‐Solid‐State Batteries

open access: yesAdvanced Materials, EarlyView.
Mechanical reconstruction reorganizes commercial Li from surface to bulk by refining surface topography, renewing the native passivation layer, and establishing a strongly (200)‐preferred texture. Native‐passivation renewal promotes interfacial Li‐ion transport, whereas texture homogenization regulates the spatial distribution of Li flux and supports ...

The Solar Neighborhood LV: Spectral Characterization of an Equatorial Sample of 580 K Dwarfs

open access: yesThe Astronomical Journal
We present a spectroscopic characterization of 580 K dwarfs within 33 pc, observed with the CHIRON echelle spectrograph ( R = 80,000) on the SMARTS 1.5 m telescope. This volume-limited sample is part of the RKSTAR survey of ∼4400 K dwarf primaries within

Programmable Microgel Degradation in Dynamic Granular Hydrogels Guides Extracellular Matrix Assembly During Tissue Repair

open access: yesAdvanced Materials, EarlyView.
This study reports on the chemical modification of hyaluronic acid to create hydrogels with hydrolytic degradability ranging from 2–28 days. Granular hydrogels that undergo timed degradation to increase porosity enhance cell invasion and provisional ECM remodeling in a muscle injury model, leading to reduced fibrosis and improved regeneration ...

Lithium abundances in Bulge-like SMR stars [PDF]

open access: yes, 2017
We analyze a sample of 21 super-metal-rich (SMR) stars, using high-resolution échelle spectra obtained with the FEROS Spectrograph at the 1.5m ESO telescope. The metallicities are in the range 0.15 < [Fe/H] < 0.5, 3 of them in common with Pompéia et al. (

Anchored Fluoro‐Shielded Solvation for Lithium Metal Batteries

open access: yesAdvanced Materials, EarlyView.
Anchored fluoro‐shielded solvation reconstructs PVDF‐based polymer electrolytes by coupling polyanionic Li+‐solvate sites with fluorinated shielding segments. This design organizes anion‐rich solvation networks, strengthens selective Li+ transport, and generates LiF‐rich solid electrolyte interphase, enabling high conductivity, wide oxidative tolerance,
