We have developed a facile dip-coating method for fabricating ordered two-dimensional (2D) self-assembled block copolymer (BCP) micelle templates on substrates. Through point-to-point adsorption on these micelle templates, 2D non-close-packed, short-range ordered gold nanoparticle (AuNP) arrays were successfully obtained. The study elucidates the governing principles of critical processing parameters: the effects of withdrawal speed and micelle concentration on template morphology, as well as the influence of nanoparticle size and micelle corona thickness on the electrostatic adsorption process, thereby enabling the controllable fabrication of large-area 2D non-close-packed nanoparticle arrays. When employed as nanoscale floating gates in non-volatile memory devices, these BCP@AuNP composite arrays demonstrate superior performance—specifically, the incorporation of AuNPs broadens the memory window and enhances device operational stability compared to pure BCP micelle template layers. This strategy offers distinct advantages including operational simplicity, high efficiency, broad applicability, and cost-effectiveness, without requiring additional pre- or post-treatment steps. The entire process demonstrates substantial potential for industrial-scale fabrication of controllable 2D non-close-packed nanoparticle arrays.

The Sloan Digital Sky Survey (SDSS) has officially launched its twentieth data release (DR20), marking the third data release for the fifth phase of the survey (SDSS-V).

Keeping hydrogen liquid at about 20 K demands exceptional insulation, since small heat leaks generate boil-off gas and raise tank pressure. A new study used 3D multiphase simulations to evaluate a semi-active system in which a secondary cryogenic coolant, liquefied natural gas or liquid nitrogen, circulates through embedded insulation channels, intercepting heat before it reaches the inner tank. In optimized configurations, simulated heat ingress fell by 43.6% with both coolants, guiding cooling-channel placement and design.

This review systematically bridges non-resonant and resonant metasurfaces, highlighting their complementary roles in shaping next-generation photonic devices. It covers physical mechanisms, key structures, and transformative applications in imaging, color routing, and displays. The fusion of both paradigms promises multifunctional, chip‑integrated meta‑devices.

This review synthesizes collective insights from the 1st China–Australia–New Zealand Water Quality Modeling Symposium (CANWaS 2024) and outlines a roadmap for strengthening international collaboration in surface water quality modeling. Organized by Jiping Jiang from Harbin Institute of Technology and Danlu Guo from Australian National University, an international research team identifies shared priorities, mutual interests, and actionable pathways—including best-practice guidelines, open knowledge sharing, and joint technological innovation—to advance predictive capacity and policy impact for global freshwater management.

Researchers have produced the first systematic map of the fluid acceleration inside the quark–gluon plasma (QGP)—the hottest fluid in nature—revealing acceleration fields of several hundred MeV, among the strongest ever achieved on Earth, with far-reaching implications for the phase structure and transport phenomena of strong-interaction matter.
