Multifunctional carrageenan/gelatin nanocomposite film incorporating carbon dot-silica nanohybrid and anthocyanins from red cabbage for intelligent shrimp packaging.

Hybrid nanoparticles loaded with licorice root-derived carbon dots (LCDs) on silica nanoparticles extracted from rice straw (SiNPs) were integrated into a carrageenan/gelatin (Car/Gel) polymer blend matrix, and anthocyanin extracted from red cabbage was added to create active and intelligent packaging films designed for monitoring shrimp freshness and extending shelf life. The films exhibited remarkable color changes with pH variations, particularly under alkaline conditions, and demonstrated high sensitivity to volatile ammonia. Additionally, the films showcased strong UV-blocking, antioxidant, and antibacterial properties, along with excellent mechanical strength and water vapor barrier performance, making them suitable for intelligent food packaging materials.

Lys-CQD catalyzed synthesis of thiourea, amide, and formamide compounds using renewable and competitive feedstocks.

The use of renewable and cheap precursors in chemical synthesis is highly beneficial, yet challenging due to their inert chemistry and the need for complex catalysts to enhance their reactivity.

FEM modeling of lateral collateral & medial collateral ligaments for use in total knee arthroplasty surgery simulation.

The objective of this study is to model the lateral collateral ligament (LCL) and medial collateral ligament (MCL) around the artificial knee joint in such a way that the virtual ligaments have the same behavior as the native ligaments around the artificial knee joint in reality. This study provides more accuracy in knee biomechanical simulation by introducing a nonlinear model for MCL and LCL ligaments and improved the modeling of ligaments by assigning nonlinear elastic behavior through achieving the force-displacement relationship in nonlinear form and assigned this relationship to the uniaxial connectors that represent the ligament bundles. The results showed that the virtual ligaments can only bear tensile loads and have the same behavior as the native ligaments that surround the artificial knee joint.

Aryana-bs: context-aware alignment of bisulfite-sequencing reads.

Background: DNA methylation is essential in various biological processes, including imprinting, development, inflammation, and numerous disorders, such as cancer.
