Fundamentals of Thermal Transport and Energy Conversion in Ultra‐High Temperature Ceramics: From Microscale Mechanisms to Macroscopic Properties

Advanced Science, Volume 13, Issue 47, 24 August 2026.
This review critically examines thermal transport and radiative properties of ultra‐high temperature ceramics for hypersonic flight, advanced nuclear systems, and next‐generation energy conversion devices. It explores phonon–photon–electron interactions, microstructural engineering, thermoelectric conversion, and machine learning‐accelerated multiscale

Studies on Migration Behavior of Fallout Nuclides in Lake Hinuma. (I).

Japanese Journal of Health Physics, 1993
Deposition of 134Cs, 137Cs and other fallout nuclides was observed at PNC O-arai Engineering Center in May 1986 after Chernobyl accident. The fallout radionuclides, especially 90Sr and 137Cs in lake water, sediments and fish have been measured in Lake Hinuma located 2km north-west of the Center since 1986 in order to investigate migration behavior of ...

Spatial variability of denudation rates and transient landscape adjustment in low‐deforming mountains (the Strengbach catchment, Vosges Mountains, France)

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
Erosion across the landscape is described at first order by a limited number (nine) of homogenous geomorphological and lithological domains. Using a dense set of basin wide denudation rates, it is possible to retrieve the contribution of each litho‐morpho‐domains as a function of their respective surface.

Experimental approach for understanding the dynamic behaviors of bentonite buffer piping erosion

Mechanical Engineering Journal, 2020
In Japan, as in other countries, bentonite-based buffer materials are expected to play roles in reducing stress from rock masses and mitigating nuclide migration in the geological disposal of high-level radioactive waste.

Temperature fluctuations controlled episodic rockfall activity in the Rwenzori Mountains (Uganda) during the Holocene

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
The alignment between rockfall deposit surface exposure 10Be ages and Holocene temperature records suggests that major rockfall events occurred episodically in response to climatic fluctuations. We conclude that temperature and its evolution enabled mechanical, chemical or bio‐chemical enhancement of fracture progression.

Migration of transuranic nuclides in earthen burial trenches at the Savannah River Plant [PDF]

, 1979
The objectives, incentives and benefits derived from the data collected at the Savannah River Laboratory on waste migration were discussed, and encapsulated transmission waste burial data were presented. Factors influencing radionuclide migration were characterized. A map of the burial ground was included. The trench sampling strategy was summarized. A

Feasibility of convection‐enhanced delivery of unlabeled 225Ac for glioblastoma: Transport, dosimetry, and clonogenic survival modeling

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Glioblastoma (GB) is an aggressive primary brain tumor with local recurrence rates exceeding 90% and a five‐year survival rate of approximately 5%. Standard treatments such as surgical resection, external beam radiotherapy (EBRT), and chemotherapy often leave residual tumor cells that are resistant to therapy.

Multiple Coupled Mathematical Model for Radionuclide Electromigration Experiments in Granites

He huaxue yu fangshe huaxue
Granite is considered an ideal medium for geological disposal of nuclear waste due to its unique stability and wide distribution. When the repository media barrier fails, granite serves as the peripheral rock medium.
