Dynamic Behavior of Oil Film between Piston Ring and Cylinder Liner : Visualization of Oil Film Rupture and Measurement of Oil Film Pressure Using Simulating Rig

open access: yesJSME international journal. Ser. C, Dynamics, control, robotics, design and manufacturing, 1995
In order to clarify the behavior of oil film between a piston ring and cylinder liner, pressure measurement and visualization of oil film are carried out simultaneously using a simulation rig. In this rig, the piston ring is simulated by a straight glass bar test piece and the cylinder by a reciprocating flat plate.

Anticorrosive Performance of Smart Epoxy Coatings With Poly(urea‐formaldehyde) Microcapsules Filled With 5‐Ethylidene‐2‐norbornene

open access: yesAdvanced Engineering Materials, EarlyView.
PUF/ENB microcapsules were synthesized based on a sequential factorial design and incorporated into an epoxy matrix. Their anticorrosive action, associated with the self‐healing mechanism, demonstrated that the addition of microcapsules to the coating improved anticorrosive performance compared to pure epoxy coatings, particularly when the encapsulate ...

From Food to Power: Hydrogel Thermoelectrics for Ingestible Electronics

open access: yesAdvanced Functional Materials, EarlyView.
We introduce a fully edible thermoelectric–electrochromic platform that harvests heat from food and converts it into a visible color change. N‐type and p‐type hydrogel thermoelectric generators connected in series power anthocyanin‐based electrochromic displays, demonstrating the feasibility of safe, biodegradable, ingestible systems for on‐food ...
