We employed the integral equation method (IEM) to simulate optical scattering by a randomly rough surface for spectroscopic ellipsometry. An explicit Mueller-matrix expression of the IEM for single scattering by moderately small surface roughness makes it possible to calculate the depolarization effect. The IEM allows a relatively rigorous assessment of the surface-scattering effect in a wide spectral range.

Objective: To evaluate the influence of in situ acid erosion on the structural and optical properties of nanoparticulate bisacrylic resin with different surface treatments, evaluating surface roughness (Ra), knoop microhardness (KHN), color change (ΔE, ΔL, ΔC, ΔH), contrast (CR) and translucency (TP).

Methods: Eighty specimens were made (n = 10 per group) and the following surface treatments were applied: U-unpolished; A-polishing with Astropol rubber tips (Ivoclar); S-Biscover LV surface sealant (Bisco) and S-Palaseal surface sealant (kulzer). For the in situ experiment, 10 volunteers wore an intraoral appliance containing eight specimens (two specimens per experimental group), with only one specimen from each experimental group being subjected to the acid process.

Annealing plays a crucial role for in enhancing the gas sensing properties of MOF-derived TiO (MIL-125). Generally, TiO transforms into different polymorphs (anatase, rutile, and brookite) during annealing, each with unique crystal structures and gas sensing properties. The aim of this research was to investigate the impact of annealing (500-650 °C) on the properties of MIL-125, which had not been previously studied.

Numerous naturally occurring biological structures have inspired the development of innovative biomaterials for a wide range of applications. Notably, the nanotopographical architectures found in natural materials have been leveraged in biomaterial design to enhance cell adhesion and proliferation and improve tissue regeneration for biomedical applications. In this study, we fabricated three-dimensional (3D) chitin-glucan micro/nanofibrous fungal-based spheres coated with collagen (type I) to mimic the native extracellular matrix (ECM) microenvironment.
