Carbon emission assessment of tunnel infrastructures: From construction to operation

open access: yesDeep Underground Science and Engineering, EarlyView.
This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...

Crystal Orientation Regulation and Dynamic Protection via Dual Interface Engineering for Dendrite‐Free Zinc Deposition

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A dual‐interface engineering strategy is innovatively proposed to achieve dendrite‐free Zn anodes through crystallographic orientation regulation and adaptive interfacial protection. By pre‐coating eco‐friendly di‐pentaerythritol, horizontal growth of ZHS along the (001) plane is induced, which in turn guides epitaxial Zn deposition on the (002) plane.

The mechanical properties of thin alumina film deposited by metal-organic chemical vapour deposition [PDF]

open access: yes, 1995
Amorphous alumina films were deposited by metal-organic chemical vapour deposition (MOCVD) on stainless steel, type AISI 304. The MOCVD experiments were performed in nitrogen at low and atmospheric pressures. The effects of deposition temperature, growth

Comparative performance of risk prediction indices for mortality or readmission following heart failure hospitalization

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1227-1236, April 2025.
Comparative performance of 7 risk prediction indices in patients hospitalized for heart failure. In this cohort of 1206 patients, the LENT index offered the greatest discrimination, calibration, and overall accuracy in predicting 30‐day composite all‐cause mortality or readmission following hospitalization for heart failure.

Finite Element Modelling of Rocking and Hybrid Precast Walls under Seismic Loading

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT In recent years, self‐centring systems have received considerable research interest in the seismic design of precast concrete structures for their ability to limit damage and satisfy resilience requirements. Rocking and hybrid structural walls, characterised by the formation of a single gap at the wall–foundation interface, mitigate damage by ...

Shaking Table Tests and Numerical Analysis of Rocking Vault‐Shaped Segmental Piers Equipped With an Annular Double Sliding System

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT To enhance the structural robustness of bridges, a rocking arch‐shaped segmental pier with a double sliding system was previously proposed as a low‐cost solution to protect bridges in developing countries. The rocking behavior is triggered by halting the sliding motion, which increases the horizontal load‐bearing capacity and limits ...
