Polyphenols are known to interact with starch to form the V-type inclusion complex or the noninclusive complex. It is hypothesized that the addition of polyphenols could improve the properties of Chinese yam (Dioscorea opposita Thunb.) starch, and the properties of the complexes could be regulated by controlling the additive amount of polyphenols.

To address the shortcomings of traditional actuators, such as large size, high energy consumption, and slow response, this study developed a conductive and responsive artificial muscle, exploring the operational principles and performance enhancement techniques for artificial muscles made from sodium alginate and graphene oxide. Initially, the research outlined a preparation methodology using sodium alginate, graphene oxide, and nanonickel as primary materials. Subsequent adjustments in the nanonickel content optimized critical performance metrics, including output force, lifespan, and deflection displacement.

In this study, a thorough examination of the chemical, thermal, and mechanical characteristics, as well as shape memory behavior at low temperatures, of blends consisting of polylactic acid (PLA) and polyurethane (TPU) is conducted. The research involves the preparation of PLA/TPU mixtures with varying concentrations of TPU using a high-speed thermo-kinetic mixing approach. Chemical, morphological, and thermal analyses were conducted on pure PLA, TPU, and PLA/TPU mixtures by using Fourier Transform Infrared (FTIR), X-ray diffraction pattern spectroscopy (XRD), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), and dynamic mechanical analysis (DMA).

Recently, significant breakthroughs have been made in the exploration of shale gas in the Lower Cambrian black shale of the Sichuan Basin, indicating a promising commercial extraction potential. However, there remains considerable controversy regarding the pore structural characteristics for this shale formation, especially in the deep-water region. To address this, this paper focused on core samples from two shale gas wells (Xa1 and Xb1) located in the slope-basin facies zone during the Early Cambrian.

Cellulose, the most abundant biopolymer on Earth, is biodegradable, nontoxic, and derived from renewable sources. Its properties and applications depend on the extraction methods and sources, making plant waste reuse a sustainable production option. This study aimed to assess the potential of cowpea pod skin () as a source of microcellulose (CPMC) using a chemical-mechanical process involving ball milling combined with acid hydrolysis.
