Optimized ITO back contact with pre‐Ga supply growth and Ag incorporation suppresses GaOx formation and interface recombination in bifacial CIGS solar cells. The devices achieve 17.25% front and 5.77% rear efficiency, delivering record bifacial power density up to 32.26 mW cm−2 in 4T perovskite/CIGS tandem architectures under enhanced albedo ...

High-strength high-performance lightweight concrete : a review (Invited)
In the last two decades, there are developments that lead to greater understanding on how and why lightweight concretes (LWC) may achieve similar or higher performance than their normal weight counterparts. The present paper reviews some of these aspects

Self-compacting lightweight aggregate concrete: design and experimental study
This study focuses on the production of self-compacted lightweight structural concrete. For this purpose, lightweight concrete was produced by replacing normal aggregate with pumice aggregate obtained from the Kayseri region.

In order to study the dynamic characteristics of the self-compacting lightweight aggregate concrete (SCLC) under uniaxial compression, 10 different strain rates (10−5–10−1/s) were set up to examine the uniaxial compressive dynamic performance of ordinary

The realization of reducing concrete self-weight is mainly to replace ordinary aggregates with lightweight aggregates; such replacement usually comes with some intrinsic disadvantages in concrete, such as high brittleness and lower mechanical properties.

A Novel Multilevel Conceptual Framework for Flood Risk Governance
ABSTRACT Globally, flood risk is increasing as climate change progresses. Contemporary flood risk management practice often utilises hydrodynamic modelling (for hazard risk assessments), social vulnerability assessments, and risk communications in silo, which fragments evidence‐based decision‐making for effective flood risk management. We hence develop
