Transforming Grain‐Boundary Brittle Precipitates to Ductility Pathways in Complex Concentrated Alloy

Advanced Science, Volume 13, Issue 19, 2 April 2026.
By engineering graded BCC/L12 interfaces, brittle precipitates in a complex concentrated alloy enable sequential deformation, realizing gigapascal strength with >20% elongation to solve the strength‐ductility trade‐off. ABSTRACT Conventional wisdom holds that hard grain‐boundary (GB) precipitates embrittle structural alloys by acting as crack ...

Leveraging Digital Advanced Manufacturing to Enable Polymer Electrolyte Fuel Cells With Ultrahigh Gravimetric Power Density

Advanced Energy Materials, Volume 16, Issue 13, 1 April 2026.
This study employs digital advanced manufacturing to develop lightweight, compact porous distributors as alternatives to conventional bipolar plates in PEM fuel cells. A graphene‐coated nickel foam achieves a power density of 1.52 W cm−2, while titanium‐based designs deliver lightweight solutions: an LPBF‐fabricated Gyroid lattice reaches 1.36 W cm−2 ...

Structural Aspects of Lithium‐Ion Conduction in the Phosphidotitanate Li8TiP4 and Its Comparison With Li7+5xTa1−xP4 and Li8−xTi1−xTaxP4

Chemistry – A European Journal, Volume 32, Issue 13, 1 April 2026.
ABSTRACT The chemical system Li/Ti/P has previously been subject to intensive investigation. However, reliable structural data for the reported phases have remained elusive. Motivated by the growing interest in phosphorus‐based lithium‐ion conductors, we have reinvestigated the synthesis, crystal structure, and physical properties of Li8TiP4.

A Database of Low‐Temperature Thermochronology in East Asia

Geoscience Data Journal, Volume 13, Issue 2, April 2026.
Spatial distribution of low‐temperature thermochronology samples in East Asia. ABSTRACT The low closure temperature of the dating system in low‐temperature thermochronology allows shallow crustal movements to be recorded. In recent decades, this approach has been used extensively in studies of orogenic belt exhumation, sedimentary basin evolution, and ...

Real‐time energy measurement of clinical carbon ion beams using a cross‐correlation time‐of‐flight method with parallel‐plate chambers

Medical Physics, Volume 53, Issue 4, April 2026.
Abstract Background In carbon‐ion radiotherapy (CIRT), the beam energy determines both the particle range and the overall dosimetric quality. Range‐verification QA devices such as Zebra and Giraffe, which are based on multilayer ionization chambers (MLICs), can verify the range but only under dedicated QA conditions, leaving any energy deviations ...

Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

Fortschritte der Physik, Volume 74, Issue 4, April 2026.
Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

A Review on Cracking in Laser Additive Manufacturing of Nickel‐Based Superalloys: Types, Formation Mechanisms, and Suppression Strategies

Rare Metals, Volume 45, Issue 4, April 2026.
ABSTRACT Nickel‐based superalloys (Ni‐based superalloys) have attracted extensive attention in laser additive manufacturing (LAM) due to their capability to directly fabricate complex and high‐performance structural components. However, the rapid melting and solidification inherent to LAM result in intense thermal cycling, which induces high residual ...
