Radiation‐Based 3D Dual‐Mode Thermal Management Devices: Advances in Active/Passive Switching for Energy‐Saving Applications

Small, EarlyView.
Heating and cooling energy demand account for nearly half of the global energy consumption. SH and RC offer sustainable, zero‐energy strategies, but single‐mode devices lack adaptability. 3D dual‐mode devices, exploiting axial, flipping, and bending deformations, provide reversible switching with dynamic or passive control, representing a promising ...

Super‐High Sodium‐Ion Conductivity of Na2.9Sb0.9W0.1S4 at Low Pressures by Systematic Pressure and Temperature Treatments

Small, EarlyView.
Systematic pressure and temperature treatment of the sodium ion electrolyte Na2.9Sb0.9W0.1S4 enabled deep insight into the effects of these parameters on the sodium conductivities and their impedance‐spectroscopic measurements, and afforded a material exhibiting a record superionic conductivity of 44.7 mS cm−1 at pressures down to 18 MPa and an ...

Influences of Ambient Temperature on Dual-Temperature-Zone Pulse Tube Refrigerator with Acoustic Power Recovery Phase Shifter

Zhileng xuebao
Pulse tube refrigerators are widely used in space detection and quantum computing due to their low vibration output at the cold end and high reliability. Dual-temperature-zone pulse tube refrigerators can simultaneously achieve dual cooling temperatures.

Response of Remote Tropical West Pacific Islands to Climate Variability: A Multiproxy Record From T‐Lake, Palau, Spanning the Early Holocene to Present

Archaeometry, EarlyView.
ABSTRACT Lake sediments are natural archives of past environmental dynamics and how these systems have responded to past climate variability. Sediment geochemistry, governed by local geology and climate processes, is unique to each lake‐catchment and geochemical proxies must be validated for each study site.

Improving fatigue resistance of translucent 4Y‐PSZ zirconia through glass gradation

European Journal of Oral Sciences, EarlyView.
Abstract To evaluate the effect of graded glass infiltration on the fatigue behavior and mechanical reliability of translucent 4Y‐PSZ zirconia before and after hydrothermal aging, disc‐shaped specimens were fabricated by uniaxial pressing and divided into control and glass‐graded groups (n = 36/group).
