3D Printing Innovations in Polymeric Porous and Patterned Architecture

Advanced Functional Materials, EarlyView.
Polymeric foams occupy a unique structural space between dense solids and open networks, where engineered void fraction governs mechanical compliance, thermal resistance, and mass transport. Additive manufacturing now enables precise spatial control over cellular architecture, unlocking designer foam structures across applications spanning crash ...

Investigations on the Dynamic Response of Adjacent Buildings Connected by Viscous Dampers

Buildings, 2022
This paper investigates the seismic performance of two adjacent buildings connected by viscous dampers. Three types of damper placement are discussed, including installing dampers within a single building, connecting two buildings at the same floor level,

Behaviour of a Torsional Vibration Viscous Damper in the Event of a Damper Fluid Shortage

Polish Maritime Research, 2023
Abstract This article presents the analysis of a damping fluid deficiency in a torsional vibration viscous damper. The problem is analysed both qualitatively and quantitatively. Experimental results are presented, showing what happens to the damper in a situation where the design of the housing is inadequate and the inertia forces ...

Pull‐and‐Push Nanotherapeutic Hydrogels: Scavenging Inflammatory Triggers While Driving Tissue Regeneration in Burn Wounds

Advanced Functional Materials, EarlyView.
A nanounit‐assembled hydrogel employing a “pull‐and‐push” strategy simultaneously scavenges pro‐inflammatory cell‐free DNA (cfDNA) and delivers regenerative therapeutics in response to burn‐induced hyperthermia. By repolarizing macrophages and promoting angiogenesis, this multifunctional platform accelerates burn wound healing, offering a blueprint for

Investigating the effect of horizontal dampers arrangement pattern in the steel moment frame structure on the progressive collapse potential

Discover Civil Engineering
Dampers are effective tools for dissipating energy and reducing structural displacement. This study investigates the role of viscous and magneto-rheological (MR) dampers, applied with a passive control approach, in improving the progressive collapse ...

Study on viscous-friction series damper for industrial facilities (Mechanism and basic performance of damper)

Nihon Kikai Gakkai ronbunshu, 2016
This study proposes a viscous-friction series damper. The series damper consists of an oil damper and a friction damper connected in series. Long period and long time seismic waves were recognized as new problems by the Great East Japan Earthquake.

Influence of Internal Rubber Damper on Cable External Viscous Damper Effectiveness

Eng, 2022
In practice, the internal rubber dampers are widely installed inside the cable guide pipe between the external viscous damper and the cable anchorage. In order to study the effect of the internal damper on the performance of the external viscous damper, the theoretical analysis model of a taut cable with an internal rubber damper and an external ...

Intelligent Acousto‐Electrical Metamaterials (IAM) for Sound Source Detection

Advanced Materials, EarlyView.
Our proposed metamaterial concept enables sound source detection using a single material, in contrast to conventional arrays that require dozens or even hundreds of transducers. We show that the coupled acoustic–vibrational–electrical responses in piezoelectric metamaterials give rise to topology‐governed charge transport, producing distinct voltage ...
