Reinforcing Efficiency of Recycled Carbon Fiber PLA Filament Suitable for Additive Manufacturing.

The use of 3D printing technology for manufacturing new products based on sustainable materials enables one to take advantage of secondary raw materials derived from recycling. This work investigates the structural performances of 3D printing composite filaments based on polylactic acid (PLA), as a matrix, reinforced by recycled carbon fiber (rCF). Carbon fibers were recovered from industrial scraps by a patented thermal process and used to produce thermoplastic composite filaments for additive manufacturing without any additional treatment and additives.

A new easy technique to identify the correct artificial hair implantation site: A case series and preliminary results.

Background: The implantation of artificial hair is a successful standardized procedure to restore bald areas or scarred alopecic surfaces of the scalp in both sexes.

Materials And Methods: Sebometric measurements were taken, pre, 1, 3, and 6 months postimplant in two symmetric frontotemporal areas of the scalp of seven volunteers to be implanted with 50 units of artificial hair. The artificial hair used in this study are Biofibre 4.

An Investigation of the Healing Efficiency of Epoxy Vitrimer Composites Based on Zn Catalyst.

The need to recycle carbon-fibre-reinforced composite polymers (CFRP) has grown significantly to reduce the environmental impact generated by their production. To meet this need, thermoreversible epoxy matrices have been developed in recent years. This study investigates the performance of an epoxy vitrimer made by introducing a metal catalyst (Zn) and its carbon fibre composites, focusing on the healing capability of the system.

Evaluation of short-term face rejuvenation effects of non-ablative bipolar radiofrequency treatment performed by Med-RF device.

Objective: Skin laxity and wrinkling are common signs of the aging process. This physiological condition of the skin is often accompanied by psychological and social concerns, especially for females, entailing considerable expenses for cosmetics and pharmaceuticals to cease or slow down its advancement. The objective of this study was to evaluate the short-term impact of a new non-ablative radiofrequency device available in the skin face cosmetic field.
