LipoGels: Robust Self‐Lubricating Physically Cross‐Linked Alginate Hydrogels Embedded with Liposomes
Physically cross‐linked alginate hydrogels embedded with 1,2‐dipalmitoyl‐sn‐glycero‐3‐phosphocholine liposomes (LipoGels) are prepared under optimized conditions to avoid shrinkage and achieve structural uniformity. LipoGels demonstrate robust mechanical strength (Young's modulus ≈1 MPa), excellent lubrication (friction coefficient ≈0.021), and ...

A Review on MXene Terminations
Surface terminations play a decisive role in determining the properties of MXenes. Their coordination, composition and stoichiometry can be tuned both during synthesis and through post synthesis methods to tailor MXenes for optimum performance in applications. This review explores the present understanding of surface terminations.

Reconfigurable Metamirrors Based on Compliant Mechanisms
Providing the basis for numerous practical applications, the reconfigurability of metadevices is of great importance. Through the integration of controlled mechanical deformation with chiral meta‐atoms, a compliant mechanism based metamirror is demonstrated for active control over the polarization of electromagnetic waves.

Stryker Osteonics: Prosthetic Knee Joint [PDF]
We examine, within a simple bearing model of a knee joint that only consideres pure sliding, the effect of the presence of a small vertical hole in the load area on the fluid film properties.

Lubricants for Inerted Lubrication Systems in Engines for Advanced Aircraft [PDF]
<div class="htmlview paragraph">The feasibility of using presently available liquid lubricants in advanced, high speed aircraft engines has been investigated with a recirculating inerted lubrication system. Three fluids performed satisfactorily for short durations of 3-10 hr in a full-scale simulated aircraft bearing and seal assembly at an outer

The disordered growth of dendrites, corrosion, parasitic side reactions, slow de‐solvation kinetics, and inherent safety risks significantly hinder the practical deployment of conventional liquid electrolyte zinc‐ion batteries. In contrast, the novel PU‐EG+DMPA‐Zn polyurethane quasi‐solid‐state electrolyte, enriched with abundant polar functional ...

Dry electrode technology revolutionizes battery manufacturing by eliminating toxic solvents and energy‐intensive drying. This work details two promising techniques: dry spray deposition and polymer fibrillation. How their unique solvent‐free bonding mechanisms create uniform microstructures for thicker, denser electrodes, boosting energy density and ...

Sizing criterial for traction drives [PDF]
A simplified traction drive fatigue analysis which was derived from the Lundberg-Palmgren theory is measured and the effects of rotational speed, multiplicity of contacts, and variation in the available traction coefficient on traction drive system life,

Bio‐Inspired Molecular Events in Poly(Ionic Liquids)
Originating from dipolar and polar inter‐ and intra‐chain interactions of the building blocks, the topologies and morphologies of poly(ionic liquids) (PIL) govern their nano‐ and micro‐processibility. Modulating the interactions of cation‐anion pairs with aliphatic dipolar components enables the tunability of properties, facilitated by “bottom‐up ...
