Active Metamaterials with Tunable Shear Nonreciprocity and Nonlinear Dynamics

Advanced Science, EarlyView.
Active gear‐based mechanical metamaterials enable simultaneous control of translational and torsional stiffnesses by 30–100×, break shear reciprocity under positive versus negative loads, broadly tune resonant frequencies, and offer programmable dynamic responses.

Multi-Objective Optimization of Base-Isolated Tanks with Supplemental Linear Viscous Dampers

Infrastructures, 2022
Base isolation of liquid storage tanks has proven to be an efficient seismic protection measure, leading to a drastic reduction of a superstructure’s distress. However, many such tanks are located near seismic tectonic faults, which generate strong pulse-

An investigation of eddy-current damping of multi-stage pendulum suspensions for use in interferometric gravitational wave detectors [PDF]

, 2004
In this article we discuss theoretical and experimental investigations of the use of eddy-current damping for multi-stage pendulum suspensions such as those intended for use in Advanced LIGO, the proposed upgrade to LIGO (the US laser interferometric ...

Socioenvironmental implications of Jatropha curcas cultivation for biodiesel supply in postmining communities

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The long‐term viability of Jatropha curcas as a biodiesel feedstock has been widely debated. Many early initiatives failed to deliver consistent economic returns despite promising environmental attributes. This study re‐evaluated J. curcas‐based systems within an integrated environmental–economic framework, focusing on their potential role in ...

Design and analysis of a three-dimensional seismic isolation device for small modular reactor building

Nuclear Engineering and Technology
Seismic isolation in nuclear power plant (NPP) buildings has been infrequently applied using a rubber-based horizontal seismic isolation system (SIS) without vertical isolation under a peak ground acceleration (PGA) of 0.3 g as the seismic design ...

Research on irregular plane mid story isolation structures in castor earthquake prone areas considering SSI effect

Frontiers in Earth Science, 2023
The rock composition of karst area is mainly limestone, which is easy to be eroded and dissolved by water, forming a complex and fragile tectonics. Under the action of earthquake, the instability of stratum is aggravated.

Sequencing Finance for Climate Resilience: Instruments, Institutions and Hong Kong's Role in Mobilising Private Capital in Southeast Asia

Business Strategy and the Environment, EarlyView.
ABSTRACT This paper investigates innovative financing strategies to mobilise private capital for climate adaptation, emphasising Hong Kong's role in advancing efforts across Southeast Asia. Using expert interviews and case studies, it addresses two key questions: which financial instruments can strengthen public–private collaboration, and what best ...

Geological and geotechnical challenges on the Great Dyke of Zimbabwe and their impact on hardrock pillar design

Deep Underground Science and Engineering, EarlyView.
The Great Dyke of Zimbabwe is notable for its rich platinum group metal deposits but poses significant geological and geotechnical challenges due to its complex rock types and structural features. Traditional pillar design methods are insufficient for addressing these complexities; the study suggests incorporating advanced techniques such as machine ...
