In this paper, it is suggested that Young's modulus of pharmaceutical tablets with different porosity can be estimated from terahertz (THz) pulse time delay. We demonstrate such a possibility using a training set of tablets compressed from starch acetate. Once the mechanical properties are taught to the THz measurement system, using an ideal tablet as a reference, it is possible to get information about the Young's modulus of the tablet. Here, we show that there are optical counterparts of classical mechanical laws that couple the Young's modulus and porosity of the tablet.

Proteoglycans, key components of non-collagenous proteins in the bone matrix, attract water through their negatively charged glycosaminoglycan chains. Among these proteoglycans, biglycan (Bgn) and decorin (Dcn) are major subtypes, yet their distinct roles in bone remain largely elusive. In this study, we utilized single knockout (KO) mouse models and successfully generated double KO (dKO) models despite challenges with low yield.

The present study investigated the effect of adding honey on the physicochemical properties, oxidative stability, lipid digestion, and price of margarine produced on a pilot scale. The margarine containing honey (MH) was compared to a control commercial margarine (MC). Honey addition modified margarine color, pH, humidity, and solid fat content, which, however, were within the ranges set for margarine standards.

Tetra-Penta-Deca-Hexa graphene (TPDH) is a new two-dimensional (2D) carbon allotrope with attractive electronic and mechanical properties. It is composed of tetragonal, pentagonal, decagonal and hexagonal carbon rings. When TPDH graphene is sliced into quasi-one-dimensional (1D) structures such as nanoribbons, it exhibits a range of behaviors, from semimetallic to semiconducting.

One of the challenges in carbon fiber production centers around the high cost of raw materials required for fiber precursors or complex production processes involving multiple steps. This research paper delves into the utilization of asphaltene sourced from Alberta oil sands as an alternative precursor material that is low cost for carbon fiber production. We investigated the carbon fiber production process using a blend of different asphaltene types via melt-spinning technology.
