Sustainable Harnessing of SiO2 Nanoparticles from Rice Husks
Rice husks, as a residue from agriculture, had been largely used as a source of power through direct incineration in major rice-producing countries. However, rice husks present an intriguing opportunity as a renewable source of SiO2, offering a low-cost adsorbent with a high surface area and ease of functionalization that can be transformed into diverse mesoporous silica structures or composites, enabling applications in catalysis, drug delivery, water treatment, etc. This dual potential of rice husks can be harnessed by combining bio-oil and syngas production through pyrolysis with the efficient extraction of SiO2, ensuring the comprehensive utilization of the biomass.

Electronics Applications of P(VDF-TrFE) Composites
Piezoelectric polymers are a class of material that belong to carbon–hydrogen-based organic materials with a long polymer chain. They fill the void where single crystals and ceramics fail to perform. This characteristic of piezoelectric polymers made them unique. Their piezoelectric stress constant is higher than ceramics and the piezoelectric strain is lower compared to ceramics.

Bright and Stable Nanomaterials for Imaging and Sensing
Optical techniques for imaging and diagnosis are at the center of the wonderous developments in the biomedical field, which are paving the way to personalized medicine. Fluorescence-based techniques, in particular, have allowed dramatic progress in the analysis of biological systems and other complex processes. This is because they present better specificity, sensitivity, contrast, and versatility than techniques based on the absorption/reflection of light. Their performance is closely related to the brightness and photostability of the light-emitting materials: the amount of light emitted for a given illumination and the ability to withstand high-power illumination without degrading.

Traditional Group-IV Material Batteries through Ion Migration
Ion migration refers to the process of ions moving within a medium driven by an external electric field or a chemical gradient. The prerequisite for the implementation of ion migration technology lies in the construction of suitable electrodes, electrolytes, and media. Group-IV materials, due to their abundant raw materials, low production costs, non-toxic nature, and excellent electrochemical properties, serve as ideal anode materials for various ion migration-based batteries. Group-IV materials, as crucial components of ion migration-driven energy storage technologies, have been a focal point of research for decades. Various studies encompass the design and fabrication of rational structures, as well as selecting metal ions with different valence states (Li+, Na+, K+, Zn2+, Mg2+, Al3+, etc.) to enhance the performance of ion batteries.

Properties of Pectic Polysaccharides
Pectin consists of many active functional groups of polysaccharides, enabling them to have much more excellent modification properties than other biopolymers. Pectin is a hydrophilic natural polymer that can absorb or retain much water and exhibit swelling properties. Hydrogels and composite materials can be formed by crosslinking and other techniques, and the matrix structure can be incorporated with various bioactive compounds. Pectin-based smart composites with physical-sensitive (light, temperature, electricity), chemical-sensitive (pH, redox, glucose), and biological-sensitive (enzymes) properties are suitable in the delivery system of bioactive compounds in addition to their suitable biodegradable and biocompatible properties. Due to its broad availability, pectin has become a prominent branch of the research and development of nature-based biomedical and healthcare areas.
