“…1 This novel category of materials are composed of biodegradable polymers or natural fibers, resulting in an innovative material possessing mechanical characteristics akin to those of conventional glass fiber-based composite materials. 2 These eco-friendly, lightweight, and sustainable materials hold the promise of revolution of various industries, such as aerospace, 7 construction and building material, 6 oil and gas industry, 227 marine and shipbuilding, 8 electrochemical, 5 textile and apparel manufacturing, electronics, 3 and pharmaceuticals. 4 Although smart biocomposites hold significant achievements, the prediction of their deformation mechanism remains a challenge because they may damage differently by compressive or tensile strain unlike metals or traditional composites.…”

“…Plastic materials are widely used for their versatility, low production cost, and easy manufacturing. Furthermore, plastic materials possess a wide range of properties, so it is possible to find them in almost all production sectors, such as packaging, clothing, medicine, and electronics. − On the other hand, the massive production and use of plastics have led to one of the main problems of the last decades: plastic waste and its disposal. − Another negative aspect is that these plastic materials are petroleum derivatives, which increases the emission of CO 2 into the atmosphere and affects climate change . To overcome this problem, recycling these plastic materials to obtain value-added products has been used to manage issues associated with their disposal. − Additionally, producing and using materials with lower environmental impact is an alternative. ,,, …”

Aliphatic polyesters are widely studied due to their excellent properties and low-cost production and also because, in many cases, they are biodegradable and/or recyclable. Therefore, expanding the range of available aliphatic polyesters is highly desirable. This paper reports the synthesis, morphology, and crystallization kinetics of a scarcely studied polyester, polyheptalactone (PHL). First, we synthesized the η-heptalactone monomer by the Baeyer−Villiger oxidation of cycloheptanone before several polyheptalactones of different molecular weights (in the range between 2 and 12 kDa), and low dispersities were prepared by ringopening polymerization (ROP). The influence of molecular weight on primary nucleation rate, spherulitic growth rate, and overall crystallization rate was studied for the first time. All of these rates increased with PHL molecular weight, and they approached a plateau for the highest molecular weight samples employed here. Single crystals of PHLs were prepared for the first time, and hexagonal-shaped flat single crystals were obtained. The study of the crystallization and morphology of PHL revealed strong similarities with PCL, making PHLs very promising materials, considering their potential biodegradable character.

In the last few years, metal nanoparticles (NPs) have become one of the major components in the field of nanotechnology. NPs with fascinating and tunable properties (size and shape) have provided solutions for many problems including water pollution which has now become alarming in the current era. Herein, natural polymer-supported AgSr bimetallic NPs have been synthesized. For this purpose, sodium alginate (Na-Alg) was used as a stabilizer along with sodium borohydride (NaBH4) as a reducing agent. The synthesized Na-Alg-supported AgSr NPs were characterized employing UV–Vis, FTIR, SEM, and XRD techniques. The spectrophotometric analysis confirmed the formation and SEM and XRD confirmed the size of NPs up to 24.18 and 12.95 nm, respectively. These NPs were tested for catalytic degradation potential against malachite green (MG) and methyl orange (MO) dyes in the aqueous medium. The catalytic activity of NPs was evaluated in terms of kinetics and percent removal of the dyes. The results revealed that the MO dye was degraded in 21 min with a removal efficiency of 86.45% and MG dye in 24 min with 91.74%. Catalytic degradation of MO and MG dyes was also monitored in the absence of AgSr NPs which showed no catalytic degradation of dyes even after half an hour. The study has confirmed that biopolymer-supported NPs can be synthesized with suitable morphology for catalytic applications and these NPs can be further used for the removal of dyes from aqueous medium.
