Deterministic formation of carbon-functionalized quantum emitters in hexagonal boron nitride

Scalable fabrication of quantum emitters with precise spatial positioning remains challenging. Here the authors present a scalable method for the deterministic fabrication of high-quality single-photon emitter arrays in hexagonal boron nitride, using nano-indentation to enable site-specific impurity insertion.

Structure and dynamics of endogenous cardiac troponin complex in human heart tissue captured by native nanoproteomics

The heterogenous nature and dynamics of endogenous protein complexes pose challenges for conventional structural biology techniques. Here, the authors develop a native nanoproteomics strategy for the enrichment and subsequent native top-down mass spectrometry (nTDMS) analysis of endogenous cardiac troponin (cTn) complex directly from human heart tissue.

Pseudo-magnetic field-induced slow carrier dynamics in periodically strained graphene

The effect of strain-induced pseudo-magnetic fields on the optical properties of graphene has not been experimentally explored yet. Here, pseudo-magnetic fields reaching values of 100 T are shown to increase by more than an order of magnitude the relaxation lifetime of hot carriers in periodically strained graphene.

Role of flexible spacers in achieving photoinduced phase transitions of azobenzene-based liquid-crystalline polymers at room temperature

This work shows that the length of flexible spacers in azobenzene (Azo)-based polymers is crucial for achieving room-temperature photoliquefaction (i.e., UV light-induced solid‒liquid phase transition). By adjusting the length of dithiol-functionalized flexible spacers, the melting temperature (T_m) of Azo polymers can be effectively modulated. Incorporating longer spacers decreases the T_m to a temperature achievable by the photothermal effect of Azo molecules, thus enabling photoliquefaction of Azo polymers at room temperature.
