Carbon Dot‐Based Mechanofluorescent Hydrogel with Tunable Fluorescence for Bioengineering Applications

open access: yesSmall, EarlyView.
Hybrid hydrogels embedded with carbon‐based quantum dots (CQDs) exhibit real‐time fluorescence change in response to compressive force. These hydrogels demonstrate multifunctionality, biocompatibility, and tunable mechanofluorescent behavior, enabling advanced applications in soft robotics.

Universal Fabrication of Graphene/Perovskite Oxide Hybrid Heterostructures

open access: yesSmall Structures, EarlyView.
This study presents a universal, catalyst‐free method for the direct growth of monolayer graphene on perovskite oxides without the need for transfer. The process yielded uniform graphene formation across different insulating substrates under identical conditions, revealing a substrate‐independent growth mechanism.

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

open access: yesStructural 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 ...

Development of a model to predict the skin friction coefficient with application to hydraulic turbines

open access: yes
This project aims to develop a model to predict the impact of surface roughness on frictional losses in hydraulic turbines using machine learning techniques. A neural network was developed and pre-trained using a synthetic dataset, where skin friction coefficients were estimated via three empirical correlations.

Ecotoxicological Evaluation of Organic Sunscreens Used Worldwide, Alone and in Mixture, on Terrestrial Plants

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT The environmental hazards of sunscreens are discussed worldwide. However, there are few ecotoxicological studies on these compounds alone for edaphic organisms, and none for their mixtures. Avobenzone (1 and 10 ng/L), octocrylene (10 and 100 μg/L), and oxybenzone (2 and 20 μg/L), alone and in binary combinations (between the lowest and the ...

Recent advances of non‐invasive sensors for smart wearable respiratory monitoring

open access: yesVIEW, EarlyView.
Respiration contains rich physiological and pathological information, making it one of the most fundamental and continuous vital signs. Respiration monitoring is a non‐invasive and simple, but incredibly powerful, tool for assessing health, managing disease, and tracking fitness.
