Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

open access: yesAdvanced Functional Materials, EarlyView.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Active Polypropylene Fibers for Controlling Shrinkage Cracks in Cement-Stabilized Materials

open access: yesCrystals
Conventional polypropylene fibers, characterized by their smooth surfaces, exhibit relatively weak bonding with cement-based materials, limiting their effectiveness in enhancing these materials’ mechanical properties.

The effect of fiber length and composition on the compressive and flexural strength of concrete [PDF]

open access: yesمهندسی عمران شریف
The use of fibers is often aimed at increasing the ductility and load-bearing capacity of the desired concrete, and controlling the spread of cracks by adding fibers to the concrete causes this.

Study of the fresh and hardened properties of fiber self-compacting concrete [PDF]

open access: yesJournal of Structural and Construction Engineering, 2019
Self-compacting concrete (SCC). was developed about four decades before since that time it has been used very scarcely due to a number of problems including : separation, lack of flowability and filling ability, high cracking potential, and thereupon low

Shape‐Morphing Nanoengineered Hydrogel Ribbons as Hemostats

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces a self‐assembling, shape‐morphing nanoengineered hydrogel ribbon system that rapidly forms porous aggregates in situ for efficient hemostasis in trauma and surgical applications. Abstract Rapid and effective hemorrhage control remains a major challenge in trauma and surgical care, particularly for complex or noncompressible wounds.
