ZeroExpander® effectiveness assessment in PEEK or PA12 in a group of paediatric patients with transverse maxillary deficiency.

European Journal of Paediatric Dentistry
AIM The aim of this article is to compare the performance of ZeroExpander® realised using PEEK or PA12 for the expansion of the maxilla in paediatric patients, exploring a new concept for approaching maxillary expansion with a metal-free fixed automatic ...

New perspectives on poly(lauryllactam) PA12: Optimization of process parameters for AROP of ω‐lauryllactam

Journal of Applied Polymer Science
This study focuses on how catalyst concentration, activator concentration, and initial polymerization temperature impact in‐situ anionic ring‐opening polymerization (AROP) of ω‐lauryllactam. Catalyst and activator roles are fulfilled by NaH and toluene‐2,

Comparative study on the thermal and tribological properties of PA12 and PA11 for coating applications

Journal of Applied Polymer Science
In this study, the performance and potential applicability of polyamide‐12 (PA12) as an alternative to polyamide‐11 (PA11), which is currently used in the coating processes of sliding tools present in cardan shafts, was investigated.

A Mechanical Model for Stress Developmentin PA12 Tube Extrusion

International Polymer Processing, 2008
Abstract In polyamide 12 tube extrusion, calibration is the key step of the process that affects the subsequent mechanical properties. In previous work it has been shown that according to the calibration conditions, a very oriented skin layer may be created, which has been correlated to an important decrease of elongation at break.

PA12 Fats and figures: how abnormal lipids unravel the truth

British Journal of Dermatology
Oral isotretinoin is the most effective treatment for severe acne vulgaris. However, its use may be limited by adverse drug reactions, including hyperlipidaemia.
