Structural performance of steel-concrete sandwich beams with carbon nanofiber reinforcement [PDF]

open access: yes, 2019
Cementitious materials such as concrete are typically characterised as quasi-brittle with low tensile strength and low strain capacity, which hence affect the long-term durability of the structure.

The Recycling of Carbon Components and the Reuse of Carbon Fibers for Concrete Reinforcements

open access: yesApplied Sciences, 2023
Carbon fiber reinforced plastics are increasingly used in all areas of industry. With the increasing number of components and semi-finished products, more and more new carbon fibers will be produced.

High-Ampacity Power Cables of Tightly-Packed and Aligned Carbon Nanotubes

open access: yes, 2014
We characterize the current-carrying capacity (CCC), or ampacity, of highly-conductive, light, and strong carbon nanotube (CNT) fibers by measuring their failure current density (FCD) and continuous current rating (CCR) values.

Chemical Characterization of Stabilized and Carbonized Polyacrylonitrile (PAN) Fibers Treated with Oleic Acid.

open access: yesMATEC Web of Conferences, 2014
Polyacrylonitrile (PAN) fiber is the best precursor for carbon fibers due to high carbon content after heat treatment. After the polymer was spun into fibers, the fibers will undergo pretreatment process with chemical solution known as post spinning ...

Alcohol decomposition on basic/acid lignin-derived submicron diameter carbon fibers [PDF]

open access: yes, 2018
The use of lignin, the second most abundant polymer in nature, along with a simple and versatile technique, electrospinning, represents an advantageous and promising approach for the preparation of carbon fibers.

The epithelial barrier theory proposes a comprehensive explanation for the origins of allergic and other chronic noncommunicable diseases

open access: yesFEBS Letters, EarlyView.
Exposure to common noxious agents (1), including allergens, pollutants, and micro‐nanoplastics, can cause epithelial barrier damage (2) in our body's protective linings. This may trigger an immune response to our microbiome (3). The epithelial barrier theory explains how this process can lead to chronic noncommunicable diseases (4) affecting organs ...

RhoA and Rac1 as Mechanotransduction Mediators in Colorectal Cancer

open access: yesAdvanced Biology, EarlyView.
Analysing RhoA and Rac1 protein levels in Colorectal cancer (CRC) samples under mechanical strain highlights their potential as diagnostic markers. Monitoring their activity could offer valuable insights into how cancer spreads, paving the way for new approaches to better understand and diagnose colorectal cancer.

Influence of the carbonization temperature on the properties of carbon fibers based on technical softwood kraft lignin blends

open access: yesCarbon Trends, 2021
Lignin is an interesting renewable resource for carbon fibers. In this work we investigate the usage of unpurified softwood kraft lignin Indulin AT for melt-spinning of lignin-fibers and the properties of resulting lignin and carbon fibers. Indulin AT is

Mechanical Properties of Domestic T700 Grade Carbon Fibers/QY9611 BMI Matrix Composites

open access: yesJournal of Aeronautical Materials, 2017
The morphologies,surface energies and surface chemical properties of the domestic T700 grade carbon fiber and the T700S carbon fiber were characterized by using scanning electronic microscopy (SEM), inverse gas chromatography(IGC) and X-ray photoelectron
