Prospects for using carbon-carbon composites for EMI shielding [PDF]

open access: yes
Since pyrolyzed carbon has a higher electrical conductivity than most polymers, carbon-carbon composites would be expected to have higher electromagnetic interference (EMI) shielding ability than polymeric resin composites.

Bioresorbable and Wireless Rechargeable Implanted Na‐ion Battery for Temporary Medical Devices

open access: yesAdvanced Functional Materials, EarlyView.
An all‐solid‐state bioresorbable Na‐ion battery is developed, composed entirely of bio‐eliminable materials. In vivo and ex vivo tests confirmed harmless disintegration of this implanted battery. Lifetime of the implanted battery can be precisely controlled by adjusting the dissolvable encapsulation layer's thickness.

One-pot synthesis of lignin-based electrospun oxygen reduction reaction electrocatalysts [PDF]

open access: yes, 2018
Owing to their adequate combination of high surface area, electrical conductivity and electrochemical resistance, carbon fibers has been used for a long time as a catalyst supports and gas diffusion layers in the electrodes of fuel cells.

Wearable Haptic Feedback Interfaces for Augmenting Human Touch

open access: yesAdvanced Functional Materials, EarlyView.
The wearable haptic feedback interfaces enhance user experience in gaming, social media, biomedical instrumentation, and robotics by generating tactile sensations. This review discusses and categorizes current haptic feedback interfaces into force, thermal, and electrotactile stimulation‐based haptic feedback interfaces, elucidating their current ...

Applicability of FT-IR Techniques and Goniometry on Characterization of Carbon Fiber Surfaces

open access: yesJournal of Aerospace Technology and Management, 2016
Carbon fibers have been widely used as structural reinforcement in aeronautical composites, because of their exceptional mechanical properties. However, carbon fibers present few polar groups on their surfaces inducing a weak interaction with some ...

Pilot–Scale Production of Carbon Hollow Fiber Membranes from Regenerated Cellulose Precursor-Part II: Carbonization Procedure

open access: yesMembranes, 2018
The simultaneous carbonization of thousands of fibers in a horizontal furnace may result in fused fibers if carbonization residuals (tars) are not removed fast enough. The optimized purge gas flow rate and a small degree angle in the furnace position may

Evaluating the System Compliance in Testing Carbon Nanotube Fibers [PDF]

open access: yesarXiv, 2017
System compliances of two testing machines (Keysight T150 and Instron 3365) were studied for the tensile testing of carbon nanotube (CNT) fibers. Due to the different gripping methods, the T150's system compliance was nearly zero, while that of the Instron was nonnegligible.

Graphite fiber surface treatment to improve char retention and increase fiber clumping [PDF]

open access: yes
Composites containing carbon and graphite fibers can release fibers into the atmosphere during a fire. This release can potentially cause failure in some types of electrical equipment.

The effect of fiber oxidation on the friction and wear behaviors of short-cut carbon fiber/polyimide composites

open access: yeseXPRESS Polymer Letters, 2007
Pitch-based short-cut carbon fibers were treated by HNO3 oxidation, thereafter the treated (CFN) and untreated carbon fibers (CF) were incorporated into polyimide (PI) matrix to form composites.
