Spectroscopy and Dynamics of a Two-Dimensional Electron Gas on top of Ultrathin Helium Films on Cu(111)

, 2016
Electrons in image-potential states on the surface of bulk helium represent a unique model system of a two-dimensional electron gas. Here, we investigate their properties in the extreme case of reduced film thickness: a monolayer of helium physisorbed on

Anomalous Stiffening of a Conjugated Polymer During Electrochemical Oxidation

Advanced Functional Materials, EarlyView.
The electromechanical response of a thienothiophene‐based conjugated polymer with triethylene glycol side chains is investigated. Electrochemical nanoindentation and atomic force microscopy reveal a modest and reversible increase in elastic modulus at room temperature upon electrochemical oxidation.

In-situ measurement of the permittivity of helium using microwave NbN resonators

, 2008
By measuring the electrical transport properties of superconducting NbN quarter-wave resonators in direct contact with a helium bath, we have demonstrated a high-speed and spatially sensitive sensor for the permittivity of helium. In our implementation a

Cold Atmospheric Plasma Selectively Disrupts Breast Cancer Growth in a Bioprinted 3D Tumor‐Stroma Co‐Culture Model

Advanced Healthcare Materials, EarlyView.
This research introduces a cold plasma‐based platform for treating breast cancer bone metastases. Using a novel bioprinted 3D tumor‐stroma model, it highlights the selective antitumor effects of plasma‐generated reactive species. The platform aims to advance non‐invasive therapeutic strategies, offering potential clinical applications in controlling ...

Multiple stellar populations and their influence on blue stragglers

, 2010
It has become clear in recent years that globular clusters are not simple stellar populations, but may host chemically distinct sub-populations, typically with an enhanced helium abundance. These helium-rich populations can make up a substantial fraction

Unlocking new contrast in a scanning helium microscope

Nature Communications, 2016
Delicate structures (such as biological samples, organic films for polymer electronics and adsorbate layers) suffer degradation under the energetic probes of traditional microscopies.

The Condensation of Helium [PDF]

Nature, 1908
IN addition to my short note printed in last week's NATURE (p. 559), let me begin by remarking that as recently as last year, in an address to the Dutch Congress of Natural Science and Medicine, I expressed the opinion that it would be scarcely possible to liquefy helium.

Advanced Nanoparticle Therapeutics for Targeting Neutrophils in Inflammatory Diseases

Advanced Healthcare Materials, EarlyView.
This review highlights recent advances in nanoparticle‐based strategies to modulate neutrophil activity in inflammatory diseases. By targeting inflammatory neutrophils, NET formation, and neutrophil apoptosis or recruitment, these approaches aim to improve therapeutic precision.
