Background: Different types of intersomatic fixation systems are available for use in the treatment of cervical disc pathologies. In this paper, we report our experience using carbon fiber cages (Brantigan I/F cage, De Puy Acromed, Raynham, MA; Mikai distrib.) for acute and chronic cervical disc pathologies.
Methods: Between 1997 and 2001, 97 patients underwent surgical treatment for cervical disc pathologies. Follow-up ranged from 1 to 60 months. In all cases a microdiscectomy according to Caspar was performed; anterior stabilization was performed in cases with evidence of instability and in post-traumatic disc herniations.
Results: A total number of 119 carbon fiber cages, ranging in height from 4 to 8 mm, were employed as well as 10 anterior plates with screws. The type of material used to fill the cages was homologous bone (50.5%), heterologous bone (22.3%), hydroxyapatite (21.1%), and autologous bone (6%). In all cases, follow-up radiograms performed after at least 6 months demonstrated bone fusion. None of the patients had either spontaneous displacement of the implant or symptoms from nerve compression.
Conclusions: These preliminary results suggest that anterior cervical fusion with carbon fiber cages are valid to restore intervertebral disc height and to promote bone fusion with low complications rate.

This study investigates the feasibility of using nano-thermal rod for deicing tunnel pavements in cold region. The heating performance of the nano-thermal rod was compared with that of carbon fiber heating wire under low voltage conditions. Experimental studies were conducted in a controlled environmental chamber to evaluate the effects of arrangement parameters (spacing, buried depth, input power) and environmental factors (ambient temperature and moisture) on heating rate and effectiveness.

Car accidents, infections caused by bacteria or viruses, metastatic lesions, tumors, and malignancies are the most frequent causes of chest wall damage, leading to the removal of the affected area. After excision, artificial bone or synthetic materials are used in chest wall reconstruction to restore the skeletal structure of the chest. Chest implants have traditionally been made from metallic materials like titanium alloys due to their biocompatibility and durability.

Background: Scanning electrochemical microscopy (SECM) is a kind of scanning probe technology that enables the obtainment of surface morphology and electrochemical information by recording changes in Faraday current triggered by the movement of probe.
Results: In this work, flexible disk ultramicroelectrode (UME) with highly repeatable geometry are fabricated through a simple and universal strategy that involves vacuum pulling the glass capillaries inserted with platinum wire (gold wire, carbon fiber, etc.), followed by a rapidly heated sealing and polishing process.

The durability and flame retardancy of cotton fabrics have been the focus of long-term research. In this paper, a method for preparing flame retardants through the direct modification of biomass was proposed, and the durable flame retardant of homologous cottonseed meal modified biomass flame retardants for cotton fabrics was achieved through biomass composition analysis and modeling. In this study, a cottonseed meal-phosphoric acid-boric acid synergistic bio-based flame retardant (CPB) was synthesized and characterized.

Background: Carbon fiber custom dynamic orthoses have been used to improve gait mechanics after lower limb trauma in military service members, with the goal of restoring function and improving outcomes. However, the effects of commercially available carbon fiber orthoses available to civilians on lower extremity joint kinetics and kinematics are poorly understood.
Research Question: The aim of this study was to examine the effect of two commercially available orthoses on lower extremity kinematics and kinetics in individuals with lower limb trauma.
