3D‐Printed Gradient Shape‐Memory Strain Sensors With Rewritable Gauge Factors

open access: yesAdvanced Functional Materials, EarlyView.
A 3D‐printed shape‐memory strain sensor combines thermomechanical programming with gradient architectural design. Preset strain rewrites the gauge factor (GF), while the gradient geometry amplifies the response through strain redistribution. Reprogrammable sensitivity enables the same sensor to detect weak pulse signals and monitor large‐amplitude ...

Phosphine-Catalyzed Asymmetric Cycloaddition Reaction of Diazenes: Enantioselective Synthesis of Chiral Dihydropyrazoles

open access: yes, 2019
Although carbon–carbon, carbon–nitrogen, and carbon–oxygen double bonds or their combinations have extensively been applied in phosphine-catalyzed asymmetric cycloaddition, a nitrogen–nitrogen double bond has never been investigated in chiral phosphine ...

Phase Engineering of Atomically Precise Nanoclusters (APNCs) of Gold and Beyond

open access: yesAdvanced Materials, EarlyView.
Engineering the structural phase of materials is of paramount importance for both fundamental research and practical applications. In this Review, we summarize the recent progress in controlling the phases of atomically precise nanoclusters (APNCs) of gold, silver and copper, as well as bimetallic systems. The phase‐enabled material properties of APNCs

Phosphine-Dependent Photoinitiation of Alkyl Thiols under Near-UV Light Facilitates User-Friendly Peptide Desulfurization

open access: yes, 2023
Peptides are steadily gaining importance as pharmaceutical targets, and efficient, green methods for their preparation are critically needed. A key deficiency in the synthetic toolbox is the lack of an industrially viable peptide desulfurization method ...

Soft Yet Tough Tanglemers Through Rapid Photopolymerization for DLP 3D Printing

open access: yesAdvanced Materials, EarlyView.
Soft yet tough tanglemers are produced through low‐initiator free radical photopolymerization and translated to DLP 3D printing. Systematic control over light intensity, initiator loading, and crosslink density reveals processing windows that balance printability, elasticity, toughness, and feature fidelity. ABSTRACT Additive manufacturing of compliant
