“…The radicalscavenging activity of Ag/SC1 nanocomposite was compared with ascorbic acid as stander reference. [49] The ABTS assay is considered one of the most commonly and sensitive techniques to identify antioxidant activity, because of its stability and simplicity of the assay and because the response of antioxidants involves faster reaction kinetics. [50] Moreover, this method uses a diodearray spectrophotometer to measure the loss of color when an antioxidant is added to the blue-green chromophore ABTS + radical that is reduced.…”

“…To perform anti-hemolytic activity, RBC suspension was used to evaluate the anti-hemolytic activity of Ag/SC1 composite and ascorbic acid was used as stander reference. [49,54] The erythrocytes cells (RBCs) were collected and washed three times with isotonic solution. Erythrocyte suspension was prepared at 10% (v/v) with PBS (pH 7.2-7.4).…”

Nanosized supramolecular complex (SC), {[Cu 2 (CN) 3 (phen) 3 ]5H 2 O}, 1, inlaid with silver nanoparticles was synthesized and characterized by X-ray powder diffraction (XRPD), Fourier transform infrared (FT-IR) spectroscopy, thermogravimetric analysis (TGA), scanning electron microscope (SEM), transmission electron microscope (TEM), and inductively coupled plasma (ICP) spectroscopy. The catalytic activity of Ag/SC1 nanocomposite as heterogeneous catalysts against methylene blue (MB) dye exhibits phenomenal degradation efficiency in presence of H 2 O 2 under different conditions better than the nanosized SC1. Scavenger techniques proved that • OH radicals represent the main oxidant species for the mineralization of hazardous dyes. The photoluminescence property of Ag/SC1 nanocomposite demonstrates its remarkable ability to act as a high-performance luminescent sensor towards nitrobenzene, Fe 3+ , Hg 2+ , and Sn 2+ ions. In vitro cytotoxicity and cell viable activity of Ag/SC1 nanocomposite against a set of different human cancer cell lines shows that the highest level was recorded against hepatocellular carcinoma (HEPG-2) cells. DNA binding ability of Ag/SC1 nanocomposite signifies that the composite has weak DNA binding activity. Antioxidant activity demonstrates that Ag/SC1 nanocomposite exhibits weak activity towards scavenging behavior of ABTS •+ and good anti-hemolytic activity of red blood cells comparing with ascorbic acid. The antimicrobial activity of Ag/SC1 nanocomposite against some bacterial strains offered better antibacterial properties than the nanosized SC1.

“…However, glue-type adhesives usually cannot be applied for instant tissue adhesion due to their weak cohesion strength [ 12 , 13 ]. Although numerous efforts have been made to explore bio-adhesives [ 14 , 15 , 16 ], such as cyanoacrylate derivatives [ 11 ], fibrin glues [ 17 ], and 3, 4-dihydroxyphenylalanine (Dopa)-based adhesives [ 18 , 19 , 20 , 21 , 22 ], building glue-type bio-adhesives suitable for tissue adhesions still remains challenging.…”

Glue-type bio-adhesives are in high demand for many applications, including hemostasis, wound closure, and integration of bioelectronic devices, due to their injectable ability and in situ adhesion. However, most glue-type bio-adhesives cannot be used for short-term tissue adhesion due to their weak instant cohesion. Here, we show a novel glue-type bio-adhesive based on the phase separation of proteins and polysaccharides by functionalizing polysaccharides with dopa. The bio-adhesive exhibits increased adhesion performance and enhanced phase separation behaviors. Because of the cohesion from phase separation and adhesion from dopa, the bio-adhesive shows excellent instant and long-term adhesion performance for both organic and inorganic substrates. The long-term adhesion strength of the bio-glue on wet tissues reached 1.48 MPa (shear strength), while the interfacial toughness reached ~880 J m−2. Due to the unique phase separation behaviors, the bio-glue can even work normally in aqueous environments. At last, the feasibility of this glue-type bio-adhesive in the adhesion of various visceral tissues in vitro was demonstrated to have excellent biocompatibility. Given the convenience of application, biocompatibility, and robust bio-adhesion, we anticipate the bio-glue may find broad biomedical and clinical applications.

“…M. H. Benzaama and co-researchers [ 25 ] conducted a comparative study of these models. Hearing loss, sleep disorders, fatigue, heart disease, and other physiological and psychological issues are just a few of the health effects that are now widely recognized as being associated with excessive noise in the workplace and in daily life [ 26 , 27 ]. As a result, it is critical to keep household noise levels under control.…”

A Critical Review on Hygrothermal and Sound Absorption Behavior of Natural-Fiber-Reinforced Polymer Composites

et al. 2022

Increasing global environmental problems and awareness towards the utilization of eco-friendly resources enhanced the progress of research towards the development of next-generation biodegradable and environmentally friendly material. The development of natural-based composite material has led to various advantages such as a reduction in greenhouse gases and carbon footprints. In spite of the various advantages obtained from green materials, there are also a few disadvantages, such as poor interfacial compatibility between the polymer matrix and natural reinforcements and the high hydrophilicity of composites due to the reinforcement of hydrophilic natural fibers. This review focuses on various moisture-absorbing and sound-absorbing natural fiber polymer composites along with the synopsis of preparation methods of natural fiber polymer composites. It was stated in various studies that natural fibers are durable with a long life but their moisture absorption behavior depends on various factors. Such natural fibers possess different moisture absorption behavior rates and different moisture absorption behavior. The conversion of hydrophilic fibers into hydrophobic is deemed very important in improving the mechanical, thermal, and physical properties of the natural-fiber-reinforced polymer composites. One more physical property that requires the involvement of natural fibers in place of synthetic fibers is the sound absorption behavior. Various researchers have made experiments using natural-fiber-reinforced polymer composites as sound-absorbing materials. It was found from various studies that composites with higher thickness, porosity, and density behaved as better sound-absorbing materials.
