Oxygen‐Tolerant Photo‐Induced Miniaturized Accelerated Atom Transfer Radical Polymerization (OPTIMA‐ATRP) for High‐Throughput Synthesis of Polymer Bioconjugates

open access: yesAngewandte Chemie, EarlyView.
Oxygen‐tolerant photo‐induced miniaturized accelerated atom transfer radical polymerization (OPTIMA‐ATRP) in water was developed for the polymerization of hydrophilic (meth)acrylate monomers under ambient or sub‐ambient (4°C) temperature and atmospheric conditions, without prior degassing, in less than 10 min, at an ultra‐small scale (< 50 µL) in ...

Anisotropic Nanofiber Architectures for Strain‐Insensitive Pressure Sensing and Stretchable Interconnects

open access: yesAdvanced Electronic Materials, EarlyView.
Electrospun PEDOT/PAAm nanofiber mats exhibit anisotropic electromechanical behavior, maintaining stable resistance under tensile strain while showing pressure‐responsive resistance modulation under vertical loading. This direction‐dependent response highlights their potential as tensile‐stable, pressure‐responsive components for deformable sensing and

On‐Demand Deconstructable Thermosets Through Cleavable Comonomer and Thermolatent Base Synergy

open access: yesAngewandte Chemie, EarlyView.
Thermosets, valued for their chemical and mechanical properties, resist recycling due to their cross‐linked structure. Weak bonds via comonomers enable degradability, but diffusion limits effectiveness. We incorporate thermolatent bases before polymerization (thermal or 3D‐VAT printing).

Ultrathin Aluminum–Air Batteries via Hygroscopic Electrolytes for Continuous Operation of Imperceptible On‐Skin Electronics

open access: yesAdvanced Energy Materials, EarlyView.
This study presents ultrathin, high‐capacity aluminum‐air batteries (AABs) for self‐sustaining, skin‐conformal electronics. By utilizing ambient moisture and oxygen alongside a LiCl‐based hygroscopic hydrogel electrolyte, the design significantly reduces battery thickness while preventing dehydration and Al self‐corrosion.

Water, Alcohols, Amines, and Amides as Formal Hydrogen‐Atom‐Transfer Reagents Through Activation With Redox‐Active Lewis Acids

open access: yesAngewandte Chemie, EarlyView.
Protic molecules containing strong O─H or N─H bonds typically resist hydrogen‐atom abstraction because of the high reactivity of the resulting heteroatom‐centered radicals. However, association of the protic molecules with redox‐active Lewis acids can provide powerful hydrogen‐atom donors or proton‐coupled‐electron‐transfer reagents.

3D‐Printable Nanoporous Thermosets via Disulfide‐Based Polymerization‐Induced Microphase Separation

open access: yesAngewandte Chemie, EarlyView.
α‐Lipoic acid‐derived degradable macro‐chain transfer agents (macroCTAs) with tunable hydrophilicity drive polymerization‐induced microphase separation (PIMS) in photocurable resins. Selective etching via disulfide cleavage then generates interconnected nanoporous thermosets, and compatibility with liquid‐crystal display (LCD) 3D printing enables the ...

Automated Alignment Powered by Computer Vision Streamlines the Two‐Photon Polymerization‐Based Micro 3D Printing of Multiscale and Multimaterial Structures

open access: yesAdvanced Intelligent Discovery, EarlyView.
Two‐photon polymerization enables high‐resolution microfabrication, but performing alignment when printing multiple structures is difficult. Here, we present a fast, robust, and open‐source protocol for automated alignment on Nanoscribe systems. Achieving ≈0.4 μm accuracy in under 5 s, our protocol reduces time and error in multimaterial printing. This

Multi‐Property Machine Learning Models to Accelerate the Transition Toward Bio‐Based Emulsion Polymers

open access: yesAdvanced Intelligent Discovery, EarlyView.
A machine learning framework simultaneously predicts four critical properties of monomers for emulsion polymerization: propagation rate constant, reactivity ratios, glass transition temperature, and water solubility. These tools can be used to systematically identify viable bio‐based monomer pairs as replacements for conventional formulations, with ...
