Decoupling Dynamics and Crosslink Stability in Supramolecular Hydrogels Using Associative Exchange

open access: yesAdvanced Materials, EarlyView.
How does reorganization impact the stability of supramolecular hydrogels? In contrast to dissociative crosslink exchange, implementing associative exchange in macroscale DNA hydrogels enables decoupling of reorganization dynamics from thermal and mechanical stability.

Ammonium Salts as Curing Agents to Obtain Ionic Epoxy Resins With a Thermoplastic‐to‐Thermoset Transition

open access: yesAdvanced Materials, EarlyView.
Ionic epoxy networks are prepared using ammonium salts as hardeners, leading to a two‐stage curing process with a thermoplastic‐like intermediate. This uncommon behavior enables extrusion and fabrication of thermoplastic prepregs that can be cured into thermoset composites.

LEAD: Literature Enhanced Ab Initio Discovery of Nitride Dusting Layers for Enhanced Tunnel Magnetoresistance and Lower Resistance Magnetic Tunnel Junctions

open access: yesAdvanced Materials, EarlyView.
Magnetic tunnel junctions (MTJs) using MgO tunnel barriers face challenges of high resistance‐area product and low tunnel magnetoresistance (TMR). To discover alternative materials, Literature Enhanced Ab initio Discovery (LEAD) is developed. The LEAD‐predicted materials are theoretically evaluated, showing that MTJs with dusting of ScN or TiN on ...

Chromatic‐Invariant Photothermal Fabrics Enabled by Narrow‐Bandgap Organic Semiconductors for Wearable Solar Energy Harvesting

open access: yesAdvanced Materials, EarlyView.
A chromatic‐invariant photothermal fabric is fabricated for outdoor activewear, realizing 4°C–8°C heating within 5 min under 1000 W m−2 illumination via NIR absorption, retaining high visible‐light reflectivity and original fabric functions, and achieving >95.3% sterilization in 20 min.

Now we’re Cooking with Gas! How Experimental Archaeology Challenges Modern Assumptions about Metal Recycling

open access: yesEXARC Journal, 2017
It is accepted knowledge that when re-melting alloys, some of the metal with a lower melting temperature is lost through oxidation, and more metal must be added in order to maintain the desired alloy proportions.
