Analysis and Suppression Method of Drag Torque in Wide-Speed No-Load Wet Clutch
Under no-load conditions, the wet clutch of vehicles generates drag torque across a wide speed range, which increases power loss in the transmission system and significantly impacts its efficiency and reliability.

Resolving the Structural Duality of Graphene Grain Boundaries
Advanced Materials, EarlyView.Cantilever ncAFM resolves the atomic structure of grain boundaries in graphene, revealing coexisting stable and metastable types. Both contain pentagon/heptagon defects, but metastable GBs show irregular geometries. Modeling shows metastable GBs form under compression, exhibiting vertical corrugation, while stable GBs are flat.

Atomistic Mechanisms Triggered by Joule Heating Effects in Metallic Cu‐Bi Nanowires for Spintronics
Advanced Materials, EarlyView.Bi doped metallic Cu nanowires are promising for spintronics thanks to the stabilization of a giant spin Hall effect. However, heat resulting from current injection forces Bi to leave solution, forcing segregation into monoatomic decorations which evolve into coherent crystalline aggregates.

Torqued and anti-torqued vector fields on hyperbolic spaces
FilomatIn this paper, we study the existence of torqued and anti-torqued vector fields on the hyperbolic ambient space Hn. Although there are examples of proper torqued vector fields on open subsets of Hn, we prove that there is not a proper torqued vector field globally defined on Hn.

Improved direct torque control using Kalman filter: application to a doubly-fed machine
, 2009 Direct Torque Control (DTC) has been extensively researched and applied during the last two decades. However, it has only first been applied to the Brushless Doubly Fed Reluctance Machine (BDFRM) a few years ago in its basic form inheriting its intrinsic

Torque and workspace analysis for flexible tendon driven mechanisms
, 2010 Tendon driven mechanisms have been considered in robotic design for several decades. They provide lightweight end effectors with high dynamics. Using remote actuators it is possible to free more space for mechanics or electronics.

Advanced Materials, EarlyView.Ionic epoxy networks are prepared using ammonium salts as hardeners, leading to a two‐stage curing process with a thermoplastic‐like intermediate. This uncommon behavior enables extrusion and fabrication of thermoplastic prepregs that can be cured into thermoset composites.

Advanced Materials, EarlyView.Magnetic tunnel junctions (MTJs) using MgO tunnel barriers face challenges of high resistance‐area product and low tunnel magnetoresistance (TMR). To discover alternative materials, Literature Enhanced Ab initio Discovery (LEAD) is developed. The LEAD‐predicted materials are theoretically evaluated, showing that MTJs with dusting of ScN or TiN on ...
