Configuration‐Encoded Cell Alignment by Light‐Gated Silicon Photovoltaic Microcell Arrays

Advanced Functional Materials, EarlyView.
Light‐gated silicon photovoltaic microcells convert pulsed illumination into localized electrical cues. Arranging otherwise similar microcells into four‐lobed, six‐lobed, or circular patterns directs fibroblasts into corresponding local arrangements without wired stimulation.

Selenium‐Integrated Cyanine Dye With Enhanced Photophysical Properties for Optoacoustic‐Guided Cancer Imaging and Therapy

Advanced Functional Materials, EarlyView.
This study introduces selenium‐integrated cyanine dye (Se‐Cyn), with superior photostability, absorption, and photothermal efficiency, outperforming ICG in NIR window. Its nanoparticle form remains stable in water, accumulates in tumors, and enables strong optoacoustic imaging and effective phototherapy outcomes.

Detailed atmospheric ice accretion surface measurement using micro‐computed tomography

Atmospheric Science Letters, 2020
Surfaces exposed to atmospheric cold temperature and humid environments are prone to ice accretion. Airplanes, electrical power transmission cables, and wind turbines are typical examples for which icing has to be considered.

Heteroengineering‐Induced Electronic Reconstruction for Ammonium‐Ion Energy Storage

Advanced Functional Materials, EarlyView.
An integrated electronic reconstruction behavior is induced by local heteroengineering on VO2(B) electrode material surface of NH4+ supercapacitor, rationally modulating the electronic structure, enabling enhanced intrinsic conductivity and extra driving force for NH4+ intercalation reaction.

Ice Nuclei in the Ultramicroscope and the Atmosphere [PDF]

Journal of Glaciology, 1949
Abstract Various attempts have been made in recent years to overcome the difficulties inherent in the study of clouds by reproducing them on a small scale in the laboratory. The present article briefly reviews some of these experiments, particularly those relating to the formation of ice crystals, and discusses the extent to which the

An airborne in-situ dataset of cloud microphysical properties in supercooled large droplet icing conditions [PDF]

Earth System Science Data
Detailed and comprehensive data sets on microphysical cloud properties in icing conditions are rare. In April 2023, fifteen research flights were performed with the SAFIRE ATR 42 research aircraft during the SENS4ICE-EU airborne measurement campaign over

Engineering Antigen Density on M13 Bacteriophage for Personalized Nanovaccine

Advanced Healthcare Materials, EarlyView.
Increasing antigen density on the phage capsid impacts phage uptake and antigen cross‐presentation by antigen‐presenting cells, leading to enhanced activation of antitumor CD8+ T cells in the draining lymph nodes. These activated CD8+ T cells subsequently recognize the antigen‐expressing tumors and mediate their specific cytotoxic killing, thereby ...
