Experimental Investigation of the Dynamic Response of Squeeze Film Dampers Made of Steel and Glass/Epoxy

Shock and Vibration, 2008
This work is devoted to the fabrication and investigation of the Squeeze Film Dampers (SFDs) which are widely used in many applications. This include the fabrication of a test rig and several dampers with different sizes and two different materials which

Structural characterization and optimum machining parameters of jute/carbon fibre hybrid reinforced epoxy composite laminates

Polymer International, EarlyView.
Hybrid jute/carbon epoxy laminates have better mechanical performance and less drilling damage by the use of optimized stacking sequence and machining parameters. Abstract Three composite laminate systems were produced using the standard hand lay‐up method: jute‐fibre‐reinforced polymer (JFRP), carbon‐fibre‐reinforced polymer (CFRP) and a hybrid of the

Synthesis of Poly(Itaconate)s With High Monomer Conversion Applying Emulsion Polymerization

Journal of Polymer Science, Volume 63, Issue 6, Page 1284-1296, 15 March 2025.
Itaconic acid and its derivatives are a promising and bio‐based substitute for oil‐based polymers such as acrylates. In this study, the optimization of polymerization of itaconic acid esters is described by applying emulsion polymerization leading to high reaction conversions and low residual monomer contents. ABSTRACT Itaconic acid and its derivatives

Dynamic Performance of a Squeeze Film Damper with a Cylindrical Roller Bearing under a Large Static Radial Loading Range

Machines, 2019
Turbomachine rotors, supported by little damped rolling element bearings, are generally sensitive to unbalance excitation. Accordingly, most machines incorporate squeeze film damper technology to dissipate mechanical energy caused by rotor vibrations and

Transforming Paper into Plasmonic Sensors: One‐Step Fabrication of High‐Enhancement SERS Nanosubstrates via Surface Energy Control

Small Methods, EarlyView.
Cellulose paper is transformed into a high‐performance plasmonic sensor through a process called SILVERED, which involves single‐step vapor deposition onto fluorosilanized fibers. Surface‐energy contrast drives uniform silver nanoparticle growth with sub‐10 nm hot‐spot gaps, achieving 2 pM detection of rhodamine B.

Posidonia oceanica Leaves as a Natural Filler for Poly(Butylene Succinate‐Co‐Adipate) Composites: Characterization and Biodegradation Assessment in Seawater

Journal of Vinyl and Additive Technology, EarlyView.
This study shows that incorporating 5–10 wt.% Posidonia oceanica, with or without micro‐talc, in PBSA preserves thermal stability, modifying crystallization behavior, and maintains good filler dispersion and interfacial adhesion. Mechanical properties are moderately stiffened.

No Charging but Protection: Lifetime Prolongation of Spontaneously‐polarized Electrets for Energy Harvesting Applications

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
A bilayer protection approach is proposed for slowing down the surface potential decay of thin films of spontaneously‐polarized electret materials. The electret and the protective films are characterized, and the protection effectiveness is investigated under the effects of light illumination, water contact and mechanical impact.

Stability Analysis of a Gear Pair System Supported by Squeeze-Film Dampers

International Journal of Rotating Machinery, 2001
This paper examines the stability of the steady-state periodic response of a gear pair system supported by squeeze-film dampers. The steady-state response of the system is obtained by using the hybrid technique of Harmonic Balance Method and Time ...
