Nano-scale hydroxyapatite particle network with uniform morphology and good crystallinity was fabricated on silica fiber by using carbon nanofibers as templates and with a methanol solution of Ca(NO3)2 x 4H2O-H3PO4. Field emission scanning electron microscopy, coupled with X-ray diffraction analysis confirmed the template effect and the existence of hydroxyapatite on silica fiber. It was clearly verified that by tuning the formation of carbon nanofibers on silica fiber, it was possible to control the properties of the resulting hydroxyapatite on silica fiber. In addition, the formation mechanism of hydroxyapatite on silica fiber via the template route was proposed.

Polylactic acid (PLA) composites with high straw content face several challenges, primarily due to the inherent brittleness of straw and its poor compatibility with the polymer matrix. In this study, scanning electron microscopy (SEM) was used to analyze the microscopic structure of wheat straw chemically modified by NaOH and the silane coupling agent, and it was concluded that both treatments effectively removed waxes and silica from the surface of the straw, enhanced fiber roughness, and improved interfacial adhesion. Notably, the silane coupling agent treatment not only facilitated the formation of chemical bonds between the straw fibers and the PLA matrix but also filled the interfiber pores, significantly increasing the structural density.

Due to intrinsic defects in blue-light-emitting perovskite materials, the charge carriers are prone to being trapped by the trap states. Therefore, the preparation of efficient blue-light-emitting perovskite materials remains a significant challenge. Herein, CsPb(Cl/Br) nanocrystal (NCs)@SiO structures were fabricated through hydrolyzing (3-aminopropyl)-triethoxysilane (APTS).

Bamboo culm has been widely used in engineering for its high strength, lightweight, and low cost. Its outermost epidermis is a smooth and dense layer that contains cellulose, silica particles, and stomata and acts as a water and mechanical barrier. Recent experimental studies have shown that the layer has a higher mechanical strength than other inside regions.
