Liquid Crystal Polymers as Intrinsically Magnetic and Programmable Soft Materials for Microrobotics

open access: yesSmall, EarlyView.
Liquid crystal polymers (LCPs) are proposed as intrinsically magnetic, programmable, soft materials for microrobotics. Magnetic torque‐driven manipulation of LCP microobjects is achieved and characterized in terms of the step‐out frequency, reaching ∼0.6 Hz in a ∼250 mT magnetic field. The orientation of LCP microobjects in the magnetic field and their

Drilling the Marathousa palaeo‐lake in Greece (Peloponnese): inferring the environmental context of a Middle Pleistocene archaeological site

open access: yesBoreas, EarlyView.
The Megalopolis Basin is located in the central Peloponnese (Greece), a region that is situated along one of the primary Pleistocene biogeographical corridors for intracontinental hominin migration. The basin comprises several hundred metres of Plio‐Pleistocene sediments alternating between clastics and lignites.

Fluid‐Induced Magnetic Enhancement in Sandstone Friction Experiments: Implications for Coseismic Fault Temperature Estimates

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Constraining peak temperature during seismic slip is essential for quantifying earthquake energy budgets and fault weakening. Rock magnetic methods provide a sensitive means of estimating shear‐induced coseismic temperature rise; however, the role of fluids in friction‐induced magnetic alterations remains poorly constrained.

Paleomagnetic Evidence of Internal Rotation in the Eastern Qiangtang and Its Relation to Distributed Strike‐Slip Faulting in the Southeastern Tibetan Plateau

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The southeastern Tibetan Plateau has undergone complex deformation due to the India‐Eurasia collision. Although late‐stage internal rotations are documented in the Lanping‐Simao Terrane to the south, it remains unclear whether similar processes have affected the north.

Fault Diagnosis of Permanent Magnet Synchronous Motor Based on Wavelet Packet Transform and Genetic Algorithm-Optimized Back Propagation Neural Network

open access: yesWorld Electric Vehicle Journal
In this paper, a fault diagnosis method for permanent magnet synchronous motors is proposed, combining wavelet packet transform (WPT) energy feature extraction and a genetic algorithm (GA)-optimized back propagation (BP) neural network.

Numerical Thermal‐Hydraulic Evaluation of an Integrated Direct‐Indirect Oil Cooling System for an Electric Motor Under Steady‐State Overload Conditions

open access: yesAdvanced Theory and Simulations, Volume 9, Issue 6, June 2026.
This study evaluates an integrated direct‐indirect oil cooling system for electric motor thermal management under steady‐state overload conditions. The results show that the combined cooling architecture improves heat removal from the winding, stator, and housing while balancing pressure drop penalties.
