Self‐Assembled Cobalt Oxide Nanobeads on the Conducting Van der Waals Semi‐Metal PtTe2 for Catalytic Heterostructure

open access: yesAdvanced Materials Interfaces, EarlyView.
Self‐assembled CoO nanobeads on the Van der Waals surface of PtTe2 were synthesized through simple thermal annealing utilizing the residual oxygen in the annealing chamber. In this study, the electrocatalytic effect for oxygen evolution reaction from CoO nanobeads on conducting PtTe2 was confirmed, elucidating the new pathway to design a ...

Development of Artificial Sebaceous Gland‐Integrated In Vitro Human Skin Model

open access: yesAdvanced Materials Interfaces, EarlyView.
Uniform 3D artificial sebaceous gland spheroids, termed SebaSpheres, are generated at high throughput using a microfluidic platform and structurally integrated into a collagen‐based skin construct containing fibroblasts and keratinocytes. This work presents a modular and scalable fabrication and integration strategy for incorporating sebaceous gland ...

Site‐Selective Polyvinylpyrrolidone Adsorption Behavior for 3D Heterogeneous Integration

open access: yesAdvanced Materials Technologies, EarlyView.
Site‐selective adsorption behavior is presented with polyvinylpyrrolidone on a Cu/SiO2 pattern wafer, which enables 3D heterogeneous integration. Owing to the site‐selective adsorption behavior and its corresponding electrostatic interaction between SiO2 nanoparticles and the Cu surface, the selectivity of Cu/SiO2 is arbitrarily controlled ...

The Political System of the Second Polish Republic (1918–1939)

open access: yesCzech Journal of Political Science/Politologický časopis, 2004
This article deals with the complicated and multifaceted topic of Polish politics between the two world wars. This time period was characterized not only by a “classical” political instability but, much more importantly, also by the instability of the whole political system.

Millisecond‐Switching Dual‐Band/Dual‐Polarization Ka‐Band Wavefront Control Enabled by a Complementary Liquid‐Crystal Metasurface

open access: yesAdvanced Materials Technologies, EarlyView.
An LCD‐compatible complementary liquid‐crystal metasurface delivers dual‐band, dual‐polarized Ka‐band wavefront control with millisecond switching via a 10‐µm LC gap. Interlaced patch/slot pairs enable independent phase tuning at 28 and 38 GHz, while strategic 45° slot rotation suppresses parasitic resonances. Measurements on a 160 × 160‐cell prototype
