Although wafer-level camera lenses are a very promising technology, problems such as warpage with time and non-uniform thickness of products still exist. In this study, finite element simulation was performed to simulate the compression molding process for acquiring the pressure distribution on the product on completion of the process and predicting the deformation with respect to the pressure distribution. Results show that the single-gate compression molding process significantly increases the pressure at the center of the product, whereas the multi-gate compressing molding process can effectively distribute the pressure. This study evaluated the non-uniform thickness of product and changes in the process parameters through computer simulations, which could help to improve the compression molding process.

Polysaccharides from Ganoderma lucidum (GLPs) exhibit unique bioactivity, but traditional cultivation yields low quantities and unstable quality, limiting their research and application. This study highlights how submerged fermentation processes enable the directed acquisition of structurally defined high molecular weight (MW) bioactive intracellular polysaccharides (IPS). The results showed that inoculation amount and fermentation scales had a significant effect on the content of high MW IPS.

Natural materials are valued for their lightweight properties, high strength, impact resistance, and fracture toughness, often outperforming human-made materials. This paper reviews recent research on biomimetic composites, focusing on how composition, microstructure, and interfacial characteristics affect mechanical properties like strength, stiffness, and toughness. It explores biological structures such as mollusk shells, bones, and insect exoskeletons that inspire lightweight designs, including honeycomb structures for weight reduction and impact resistance.

Article Synopsis
- The human microbiome consists of microorganisms like bacteria and fungi that impact health, with imbalances (dysbiosis) linked to diseases such as asthma and obesity.
- Current research is exploring how the gut microbiome specifically affects joint health and diseases like osteoarthritis through inflammatory responses triggered by dysbiosis.
- The review aims to enhance our understanding of the microbiome's role in disease and emphasizes the need for further studies on the joint microbiome's impact on conditions like periprosthetic joint infection.

As a special kind of supramolecular compound with many favorable properties, pillar[]arene-based supramolecular polymer networks (SPNs) show potential application in many fields. Although we have come a long way using pillar[]arene to prepare SPNs and construct a series of smart materials, it remains a challenge to enhance the mechanical strength of pillar[]arene-based SPNs. To address this issue, a new supramolecular regulation strategy was developed, which could precisely control the preparation of pillar[]arene-based SPN materials with excellent mechanical properties by adjusting the polymer network structures.
