Article Abstract
Historically, amorphous solid water (ASW) films have been created by physical vapor deposition both naturally on interstellar particles and in the laboratory. The present study focuses on the role of the mobile surface layer, which can be observed during vapor deposition and characterized by dielectric relaxation techniques. It is shown that the mobility of the surface layer can determine whether an as-deposited film is porous (p-ASW), collapsed (c-ASW), or crystallized to cubic ice (I_{c}). The latter case occurs when the fictive temperature of the surface reaches deep into the so-called "no man's land", whereas the actual temperature remains below that of the glass transition at T_{g}. The dynamics of this surface layer is independent of deposition temperature in the 15 to 120 K range.

Ni-Fe (oxy)hydroxides are among the most active oxygen evolution reaction (OER) catalysts in alkaline media. However, achieving precise control over local asymmetric Fe-O-Ni active sites in Ni-Fe oxyhydroxides for key oxygenated intermediates' adsorption steric configuration regulation of the OER is still challenging. Herein, we report a two-step dealloying strategy to fabricate asymmetric Fe-O-Ni pair sites in the shell of NiOOH@FeOOH/NiOOH heterostructures from NiFe Prussian blue analogue (PBA) nanocubes, involving anion exchange and structure reconstruction.

The detection of biological nanoparticles (NPs), such as viruses and extracellular vesicles (EVs), plays a critical role in medical diagnostics. However, these particles are optically faint, making microscopic detection in complex solutions challenging. Recent advancements have demonstrated that distinguishing between metallic and dielectric signals with twilight off-axis holographic microscopy makes it possible to differentiate between metal and biological NPs and to quantify complexes formed from metal and biological NPs binding together.

Undesired ice accumulation on infrastructure and transportation systems leads to catastrophic events and significant economic losses. Although various anti-icing surfaces with photothermal effects can initially prevent icing, any thawy droplets remaining on the horizontal surface can quickly re-freezing once the light diminishes. To address these challenges, we have developed a self-draining slippery surface (SDSS) that enables the thawy droplets to self-remove on the horizontal surface, thereby facilitating real-time anti-icing with the aid of sunlight (100 mW cm).

Transcranial alternating current stimulation (tACS) enables non-invasive modulation of brain activity, holding promise for cognitive research and clinical applications. However, it remains unclear how the spiking activity of cortical neurons is modulated by specific electric field (E-field) distributions. Here, we use a multi-scale computational framework that integrates an anatomically accurate head model with morphologically realistic neuron models to simulate the responses of layer 5 pyramidal cells (L5 PCs) to the E-fields generated by conventional M1-SO tACS.

Distinctive polymer brushes (PBs) play a crucial role in providing a nonpreferential (neutral) surface for vertical orientation of block copolymers (BCPs). This bottom-up approach effectively aligns the formation of vertical lamellar and cylinder lattice structures from the BCP, which is crucial for nanopatterning and other applications. In conventional BCP self-assembly techniques, random copolymer brushes are commonly employed to achieve substrate neutrality.
