A Platinum (II) Polyyne Oligomers Donor for Efficient Ternary Organic Solar Cells

Solar RRL, EarlyView.
Platinum (II) polyyne oligomers P5 are used as a donor in a ternary organic solar cell. The average power conversion efficiency of 16% surpasses the international record for [Pt] (II) polyyne oligomers. PC71BM speeds up the rise time for electron transfer and slows down the recombination time.

Performance analysis of strengthening reinforced concrete beams under pure torsion using galvanized steel sheets: Experimental and numerical investigation

Structural Concrete, EarlyView.
Abstract Reinforced concrete (RC) beams can be subjected to torsion, and failure due to torsion is brittle and poses a significant risk to occupants. Moreover, strengthening of existing RC beams in torsion may be required due to the upgrade of the structures or as part of structural rehabilitation.

Modeling the response of UHPC shear‐critical beams: Integrating nonlinear finite element analysis and artificial neural network

Structural Concrete, EarlyView.
Abstract An analytical framework suited for the analysis of shear‐critical ultra‐high performance concrete (UHPC) members is presented. The numerical methodology utilizes a nonlinear finite element analysis formulation integrated with an artificial neural network (ANN) that characterizes the UHPC tension response based on its mix design. In addition, a

A new smooth failure criterion for concrete inspired by Lubliner's condition

Structural Concrete, EarlyView.
Abstract A new failure criterion with 10 parameters is proposed, based on Lubliner's idea of joining two Drucker–Prager cones. The novelty lies in the way of introducing deviatoric shape variation: through two Podgórski's functions. This feature allows for improving plane stress cross‐section's compatibility with experimental data.

Impact of half‐joint failures on RC girder bridges: A robustness quantification study

Structural Concrete, EarlyView.
Abstract The robustness of bridge structures is critical to ensuring safety and service continuity, particularly in aging infrastructure exposed to degradation and unexpected loads. Reinforced concrete (RC) half‐joint bridges—widely built in Italy between the 1950s and 1970s—exhibit specific vulnerabilities due to inspection challenges, durability ...

Dual potential capacity model for short and deep reinforced concrete members containing steel fibers

Structural Concrete, EarlyView.
Abstract This study presents an analytical model for estimating the shear strength of short and deep steel fiber‐reinforced concrete (SFRC) members with a shear span‐to‐depth ratio less than 2.5. To this end, a dual potential capacity model (DPCM) is developed based on the demand‐capacity approach for evaluating the shear strength of SFRC beams that ...

Numerical analysis of the effects of corrosion on the punching shear capacity of reinforced concrete flat slabs with openings

Structural Concrete, EarlyView.
Abstract The reinforcement corrosion is one of the main degradation mechanisms in reinforced concrete structures. Its effects can harm structural elements by reducing mechanical capacity, mainly due to diminished reinforcement properties and expansive reactions within the concrete.

Performance enhancement of reinforced concrete columns using stainless steel and galvanized steel plates: Experimental and numerical investigation

Structural Concrete, EarlyView.
Abstract This study introduces an innovative approach to strengthening defected reinforced concrete (RC) columns using externally bonded stainless steel and galvanized steel plates. Unlike conventional strengthening methods, this technique replaces traditional transverse stirrups with steel sheets, providing enhanced confinement and ductility.
