AI Article Synopsis
- The study focuses on light scattering techniques for analyzing polydisperse spheroids, specifically using cellulosic nanowhiskers (CNW), by applying mathematical models within the Rayleigh-Gans-Debye limit.
- Polydispersity indices were determined through fitting theoretical models to experimental data, resulting in length polydispersity of 2.3 and diameter polydispersities of 2.1 and 3.0 for samples treated with sulfuric and hydrochloric acids, respectively.
- The results enabled the calculation of average dimensions for CNW, yielding lengths of 244 nm for hydrochloric acid and 272 nm for sulfuric acid, highlighting a new efficient methodology for characterizing
Article Abstract
Mathematical treatment of light scattering within the Rayleigh-Gans-Debye limit for spheroids with polydispersity in both length and diameter is developed and experimentally tested using cellulosic nanowhiskers (CNW). Polydispersity indices are obtained by fitting the theoretical formfactor to experimental data. Good agreement is achieved using a polydispersity of 2.3 for the length, independent of the type of acid used. Diameter polydispersities are 2.1 and 3.0 for sulfuric and hydrochloric acids, respectively. These polydispersities allow the determination of average dimensions from the z-average mean-square radius (

Injuries involving the Atlas (C1) and Axis (C2) vertebrae of the cervical spine present significant clinical challenges due to their complex anatomy and potential for severe neurological impairment. Traditional imaging methods often lack the detailed visualization required for precise surgical planning. This study aimed to develop high-resolution 3D models of the C1 and C2 vertebrae to perform a comprehensive morphometric analysis, identify gender differences, and assess bilateral symmetry to enhance surgical accuracy.

: The parallel stent graft endovascular aortic repair (PGEVAR) technique is an off-the-shelf option used for elective complex abdominal aortic aneurysm repair with acceptable outcome results, as reported so far. The PGEVAR technique, using chimney or periscope parallel grafts, can also be used for patients with ruptured complex abdominal aortic aneurysms. However, only few data about the mid- to long-term outcomes are available.

The number of revision anterior cruciate ligament reconstruction (RACLR) procedures is increasing in proportion to the increase in the number of anterior cruciate ligament reconstruction (ACLR) procedures. Although approximately 50-75% of these procedures can be performed in a single-stage procedure, not all of them can. The choice of graft may influence the results of RACLR.

Pultruded carbon fiber-reinforced composites are attractive to the wind energy industry due to the rapid production of highly aligned unidirectional composites with enhanced fiber volume fractions and increased specific strength and stiffness. However, high volume carbon fiber manufacturing remains cost-prohibitive. This study investigates the feasibility of a pultruded low-cost textile carbon fiber-reinforced epoxy composite as a promising material in spar cap production was undertaken based on mechanical response to four-point flexure loading.

This study explores the potential of using underutilized materials from agricultural and forestry systems, such as rice husk, wheat straw, and wood strands, in developing corrugated core sandwich panels as a structural building material. By leveraging the unique properties of these biobased materials within a corrugated geometry, the research presents a novel approach to enhancing the structural performance of such underutilized biobased materials. These biobased materials were used in different lengths to consider the manufacturing feasibility of corrugated panels and the effect of fiber length on their structural performance.
