A Different Perspective on the Solid Lubrication Performance of Black Phosphorous: Friend or Foe?
Researchers investigate black phosphorous (BP) as a standalone solid lubricant coating through ball‐on‐disc linear‐reciprocating sliding experiments in dry conditions. Testing on different metals shows BP doesn't universally reduce friction and wear. However, it achieves 33% friction reduction on rougher iron surfaces and 23% wear reduction on aluminum.

Reflection and Exclusion of Shear Zones in Inhomogeneous Granular Materials [PDF]
Shear localization in granular materials is studied experimentally and numerically. The system consists of two material layers with different effective frictions. The presence of the material interface leads to a special type of "total internal reflection" of the shear zone.

Mechanisms of De‐icing by Surface Rayleigh and Plate Lamb Acoustic Waves
Ice accretion impacts daily life, renewable energy generation, maintenance, and security in industries and aeronautics. Acoustic waves (AW) are a promising method for ice removal, although de‐icing mechanisms require further investigation to optimize energy efficiency.

Geology of late-Variscan Sàrrabus pluton (south-eastern Sardinia, Italy)
This paper deals with the geological mapping of the late-Variscan Sàrrabus pluton, (south-eastern Sardinia), a shallow multiple and composite igneous complex dominated by several generations of granodiorites, metaluminous and peraluminous granites and ...

Strain localization in a shear transformation zone model for amorphous solids [PDF]
We model a sheared disordered solid using the theory of Shear Transformation Zones (STZs). In this mean-field continuum model the density of zones is governed by an effective temperature that approaches a steady state value as energy is dissipated. We compare the STZ model to simulations by Shi, et al.(Phys. Rev. Lett. 98 185505 2007), finding that the

Kinematics of the Phippsburg Shear Zone at Hermit Island and the Wood Islands, Small Point, Maine [PDF]
The Phippsburg Shear Zone is located within the Casco Bay restraining bend associated with the Norumbega fault zone in south central Maine. Mapping of the shear zone was conducted at Hermit Island during the summer of 2011 as part of an EDMAP grant.

Using novel probe‐based metrics, this study evaluates lattice structures on criteria critical to cellular solid optimization. Triply‐periodic minimal surface (TPMS) lattices outperform other lattices, offering more predictable mechanical behavior in complex design spaces and, as a result, higher performance in optimized models.

Shear transformation zone analysis of shear reversal during granular flow [PDF]
Experimental measurements of the onset of granular flow are directly compared to predictions of the "shear transformation zone" (STZ) theory of amorphous plasticity. The STZ equations make it possible, on a coarse grained level, to incorporate the anisotropy of the particle contact network and its dynamic evolution including changes in the contact ...

Structure and Rheology of the Sandhill Corner Shear Zone, Norumbega Fault System, Maine: a Study of a Fault from the Base of the Seismogenic Zone [PDF]
Determining the structure and rheology of a seismogenic fault at frictional-to-viscous transition (FVT) depths is vital for understanding its strength and behavior. Few studies describe a fault from within this depth level, so the architecture of a shear
