Long‐term outcomes of microsurgical interdental papilla reconstruction: 13‐year and 18‐year case follow‐ups

open access: yesClinical Advances in Periodontics, EarlyView.
Abstract Background Loss of the interdental papilla compromises esthetics, speech, and hygiene, significantly affecting quality of life and psychological well‐being. Reconstruction has long been considered unpredictable, particularly in Cairo RT3 cases with advanced interproximal bone loss.

Effect of Clay on Crystallization Kinetics of Polyamide 6

open access: yes, 2016
Polyamide 6 has two phases: α phase and ɣ phase. Adding fillers should not change any phase. However, adding clay nanoparticles to polyamide 6 changes its phase from stable α phase to meta-stable ɣ phase. We would like to know why this happens.

Friction And Wear Performance Of Polyamide 6 And Graphite And Wax Polyamide 6 Composites Under Dry Sliding Conditions

open access: yes, 2012
The friction and wear performance of pure polyamide-6 (PA-6), 5 wt%, 15 wt% graphite filled polyamide-6 and 4 wt% wax filled polyamide-6 (PA-6+4% wax) sliding against stainless steel under dry sliding conditions were studied using a pin-on-disc ...

Peroxodisulfate‐Enhanced Leaching of Deep‐Sea Manganese Crusts and Sulfides

open access: yesChemie Ingenieur Technik, EarlyView.
Ammonium peroxodisulfate enables efficient leaching of deep‐sea manganese crusts and massive sulfides while offering electrolytic recycling. High leaching yields for V, Mn, Co, Mo, Sn, and W, along with complete leaching of As and Sb, highlight its potential as a powerful and sustainable oxidant for marine resource processing.

Microwave‐assisted catalytic pyrolysis of textile wastes: Synergistic effects and product characteristics

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study examines the microwave‐assisted catalytic pyrolysis (MACP) of individual and blended textiles (cotton, polyester, nylon 6) using ZnO and a ZnO/natural zeolite catalyst. In a custom‐built microwave reactor operated at 500°C, 1 kW power, and a 15‐min residence time, textile wastes were pyrolyzed.
