Summary: Injection molding leads to layered anisotropic morphology across sample thickness due to varying shear and cooling rates. This study used scanning small-angle X-ray scattering to observe and quantify the hierarchical structure distribution in injection-molded low-density polyethylene (LDPE) parts with different viscosities. The combination of scattering data, injection molding simulations, and tensile testing revealed that oriented shish-kebab structures and elongated spherulite structures consisting of semicrystalline ellipsoids contribute to high ultimate tensile strength in the flow direction. Moreover, a higher degree of orientation is found near the injection gate and in LDPE with higher viscosity, caused by elevated shear and cooling rates during the injection molding process.

Summary: Gold nanoparticles (AuNPs) were incorporated beneath the ZnO thin films and were found to affect the electrical and optical properties of the films. The presence of AuNPs increased the carrier concentration and the films exhibited different emission and Raman spectra. This study provides a simple method to control the properties of ZnO thin films by incorporating AuNPs.

Summary: This paper systematically studied the effects of defects such as carbon antisite, vacancy, interstitial, and substitution of carbon by nitrogen and boron on the structural, mechanical, and electrical properties of 2D SiC using first-principles calculations. It was found that defects did not cause structural reconstruction for 2D SiC, and carbon antisite and interstitial were likely to be formed spontaneously. The bandgap of 2D SiC was slightly reduced by most defects except for nitrogen substitution, and prominent additional charge states were generated in the bandgap. Moreover, these defects significantly reduced the overall carrier mobility of 2D SiC.

Summary: This study provides a molecular interpretation of the relationship between structural changes in fibers and mechanical properties of fabrics under different heat exposures. Changes in crystallinity and lamellar spacing of fabrics were observed, impacting mechanical properties. Thermal decomposition occurs at temperatures above the degradation point, potentially posing a danger to users.

Summary: The properties and applications of NTC oxides, NixMn3-xO4, are influenced by the Ni:Mn ratio, valence states, defects, and cation distribution in the spinel structure. This study improved the accuracy of determining the distribution of nickel and manganese cations in the spinel structure of Ni0.66Mn2.34O4 oxide by considering the presence of tetrahedral vacancies. Additionally, the stability of cubic Ni0.66Mn2.34O4 under pressure was investigated, and the bulk modulus and its derivative were determined using X-ray powder diffraction and a diamond anvil cell.

Summary: Postoperative peritoneal adhesions, a common complication of abdominal and pelvic surgery, can greatly impact patients' quality of life and financial burden. This study developed chitin-based crosslinked hydrogels with excellent properties, such as biocompatibility, resistance to protein adsorption, and integration into the extracellular matrix. These hydrogels effectively inhibited postoperative peritoneal adhesions in rat models and provide a new anti-adhesion strategy.

Summary: The research introduces alkalization of Sunn Hemp fiber with different alkali concentrations and soaking periods, finding that the 10% treated composite soaked for 6 hours has lower dielectric constant and loss. AC conductivity increases with concentrations and soaking time, with the 20 K10 composite showing the highest ε' and tan δ due to the formation of more amorphous components.

Summary: The study aims to develop and investigate kapok husk-reinforced epoxy composite, focusing on characterizing both the kapok husk and its reinforced composite. Different treatment methods (chemical/physical) were studied to make the kapok husk filler compatible with hydrophobic epoxy resin. The structural characterization of kapok husk revealed higher crystallinity in the treated fillers, with microwave-treated fillers showing better mechanical properties in composite testing. The dielectric characterization showed that chemical and microwave-treated fillers had higher and lower dielectric constants, respectively.

Summary: This paper investigates the chemical treatment of Sunn Hemp fiber using potassium hydroxide (KOH) to reduce noncellulosic components on its surface. The experimental results show that a high concentration of KOH solution can increase the crystallinity and crystalline size of cellulose, as well as alter the surface morphology and functional group elements of the fiber. The mechanical and dielectric studies reveal that the increased crystallinity leads to enhanced flexural and tensile strength in the composite material, and the conduction process follows the overlapping large polaron tunneling (OLPT) mechanism.

Summary: This study conducted experimental research on Sunn Hemp fiber and its reinforced composite, focusing on the structural and physical properties of the fiber and composite. The research found that the treated fiber showed increased crystallinity and crystallite size, while its basic crystallinity remained unchanged. The morphology of the treated fiber exhibited fibrillation and rough surfaces, but a higher degree of treatment made the fiber more brittle and carbonized. Changes in hydrophilicity and crosslinking density affected the flexural and tensile properties of the treated composites.

Summary: The present study aims to establish a correlation between macromolecular parameters obtained from small angle X-ray scattering (SAXS) analysis of pretreated sunn hemp fibers and the dielectric and mechanical properties of their composites. Different pretreatment methods, including dewaxing, alkalization, and microwave irradiation, were used to modify the structure of the fibers, which in turn influenced the macromolecular parameters. The modified fibers showed improved mechanical and electrical properties in the reinforced composites.
