Beyond Conventional Cooling: Advanced Micro/Nanostructures for Managing Extreme Heat Flux

Advanced Materials, Volume 38, Issue 5, 22 January 2026.
This review examines the design, application, and manufacturing of biomimetic or engineered micro/nanostructures for managing high heat‐flux in multi‐level electronics by enhancing conductive, convective, phase‐changing, and radiative heat transfer mechanisms, highlighting their potential for efficient, targeted thermal management, and future prospects.

Spacecraft Telemetry Monitoring Method Based on Dimensionality Reduction and Clustering

JOURNAL OF THE JAPAN SOCIETY FOR AERONAUTICAL AND SPACE SCIENCES, 2011
Development of intelligent system monitoring and fault detection techniques for spacecraft is of a great interest in the space engineering. In this paper, we propose a “data-driven” anomaly detection framework for spacecraft telemetry data using dimensionality reduction and clustering techniques.

Open‐ and Closed‐Loop Recycling of Polyesters and Post‐Consumer Waste Under Industrially Relevant Conditions Using Bisguanidine Organocatalysts

ChemSusChem, Volume 19, Issue 1, January 2026.
The chemical recycling of polylactide (PLA), polyethylene terephthalate (PET), and polycaprolactone (PCL) is performed using bisguanidine organocatalysts. Intensive kinetic studies of the methanolysis and ethanolysis of PLA were performed. The most active organocatalyst was successfully applied in the depolymerization of ternary plastic mixes of PLA ...

The Effect of Tip Design on Technological Performance During the Exploration of Earth, Lunar, and Martian Soil Environments

Journal of Field Robotics, Volume 43, Issue 1, Page 387-408, January 2026.
ABSTRACT This paper investigates the penetration performance of soil‐burrowing probes with different tip designs during shallow‐depth penetration in various media, including terrestrial soils (Hostun sand) and well‐characterized planetary soil simulants (LHS‐1 Lunar regolith simulant and MGS‐1 Martian regolith simulant).

Analysis of Field-Aligned Currents in the High-Altitude Nightside Auroral Region: Cluster Observation

Journal of Astronomy and Space Sciences, 2019
In this paper we present analysis of current density when the Cluster spacecraft pass the nightside auroral region at about 4-5 RE from the center of Earth. The analysis is made when the inter-spacecraft separation is within 200 km, which allows all four

Evolution of kinklike fluctuations associated with ion pickup within reconnection outflows in the Earth's magnetotail

, 2009
Magnetic reconnection (MR) in Earth's magnetotail is usually followed by a systemwide redistribution of explosively released kinetic and thermal energy.
