Herein we correlate secondary structure perturbation with changes in the solid-state molecular architectures of an elongated hexagonal plate-shaped foldecture derived from the self-assembly of rigid 12-helical β-peptide foldamers to which a flexible C-terminus α-leucine moiety has been appended. This study provides the first complete characterization of the directional molecular packing patterns of individual foldamer components within a foldecture, from which a 3D molecular-level picture of the entire foldecture was unambiguously constructed.

This article presents the authors' design of an electronic stethoscope intended for use during online medical consultations for patient auscultation. The goal of the project was to design an instrument that is durable, user-friendly, and affordable. Existing electronic components were used to create the device and a traditional single-sided chest piece.

Statement Of Problem: The mechanical properties and microstructure of cobalt chromium (Co-Cr) alloys should be considered when choosing the best alloy for each clinical situation. More information is needed on the digital manufacturing methods of metals in dentistry, such as computer numerical control (CNC), and direct laser metal sintering (DMLS).
Purpose: The aim of this study was to investigate the effect of the 3 different Co-Cr manufacturing processes on the mechanical properties and microstructure of Co-Cr dental alloys.

In this study, zinc oxide (ZnO) nanoparticles were prepared and modified using a wet chemical method with different concentrations of Ag and Cu nanoparticles. The objective was to improve the mechanical, optical, and antibacterial properties of the coated paper by using the prepared pigments. The long-term antimicrobial effects of the coated paper were evaluated over 25 years.

Article Synopsis
- The fungus Puccinia helianthi causes rust disease in Helianthus annuus, leading to significant economic losses, and this study uniquely examines its spore structure.
- The research utilizes light microscopy (LM), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) to analyze the development and morphology of pycniospores and aeciospores.
- Findings highlight the complex structure of these spores and their similarities and differences with other Puccinia species, contributing valuable insights for mycologists in rust identification and understanding plant-fungi interactions.

The present study aimed to provide comprehensive morphological features of the bronchial and parabronchial systems using cast, histological, histochemical, and scanning electron microscopy techniques, with new insights into the parabronchial topographic distribution system on 22 white Pekin ducks. Casting illustrated that the medioventral secondary bronchi (MVSB) were the largest, but the posterior (POSB) ones were the smallest. The primary (PB) and secondary bronchi (SB) were lined with thin pseudostratified, ciliated columnar epithelium.
