A thin-film optical coating exhibits Fano resonance showing promising applications in structural colouring of transparent objects and hybrid thermal and photovoltaic power generation.
Tackling obesity from different angles might result in better therapeutic outcomes. Here the authors present a virus-like particle targeted to adipose tissues that combines photodynamic therapy and adipose browning induction to induce weight loss in animal models, and use photoacoustic imaging to monitor the treatment progress.
Stochastic orbital dynamics of individually coupled Co atoms on black phosphorus enables the realization of a Boltzmann machine capable of self-adaption.
Tumour relapse after resection undermines the efficacy of surgical treatment for glioblastoma multiforme. Here the authors present a hydrogel that can be injected in the tumour cavity after resection and that promotes antitumour immunity, reducing postoperative cancer growth in animal models.
The careful optimization of all components of a quantum emitter single photon source yields over 50% end-to-end efficiency, a benchmark for optical quantum technologies.
High efficiency, coherence and indistinguishability are key requirements for the application of single-photon sources for quantum technologies, but hard to achieve concurrently. A gated quantum dot in an open, tunable microcavity now can create single photons on-demand with an end-to-end efficiency of 57%, preserving coherence over microsecond-long trains of single photons.
Targeting of the peptide hormone relaxin to injured mouse liver, via a nanoparticle/gene therapy approach, switches pro-fibrotic hepatic macrophages to a restorative phenotype that orchestrates tissue repair.
The hormone peptide relaxin attenuates liver fibrosis by inducing quiescence of activated hepatic stellar cells. In this paper the authors show that hepatic macrophages play a key role in mediating the antifibrotic effects of relaxin in animal models and propose a nanotechnology-based approach to alleviate liver fibrosis.
Broken inversion symmetry in a type-II Weyl semimetal TaIrTe4 enables observation of the room-temperature nonlinear Hall effect as well as wireless radiofrequency rectification.
Increasing the fatigue life of shape memory alloys often compromises other mechanical properties such as yield strength and plastic deformation behaviour. Introducing a mixed nanostructure of crystalline and amorphous phases can enable superelasticity in NiTi micropillars with recoverable strain of 4.3%, yield strength of 2.3 GPa and 108 reversible-phase transition cycles under a stress of 1.8 GPa.
This Review summarizes the development history of Pt-based nanocatalysts and recent analytical studies to identify the technical issues in the automobile application, proposing promising strategies for overcoming the trade-offs among the efficiency,power density, and durability of polymer electrolyte fuel cells.
Self-assembled nanoribbons with extensive and collective intermolecular interactions exhibit robust mechanical properties, enabling their translation to macroscopic solid-state threads.
Spin–orbit torque in heavy metal/ferromagnet heterostructures is promising for all-electric control of magnetic memory, but has so far required an additional symmetry breaking in the design to switch perpendicular magnetization. Instead, a low symmetry at the interface can give rise to out-of-plane spin torque and switch the magnetization deterministically.
Typically, quasiparticles are injected into superconductors at energies comparable to the pairing energy in order to gain insights into quasiparticle dynamics. Tunnelling spectroscopy of a mesoscopic superconductor under high electric field now provides insights into a regime where electrons impinge with 106 times the pairing energy.
Flexibly designed nanomaterials can trigger specific immune responses and might offer promising alternatives to traditional immunosuppressive therapies, cancer immunotherapies and vaccine formulations.
Chemoresistant cancer stem-like cells (CSCs) can be selectively killed by a nanoparticle, which releases an agent under hypoxic conditions that induces CSC differentiation, and a chemotherapeutic drug in response to reactive oxygen species in differentiating CSCs.
