One-Step Densification of Carbon/Carbon Composites Impregnated with Pyrolysis Fuel Oil-Derived Mesophase Binder Pitches

open access: yesC, 2020
Carbon/carbon (C/C) composites are conventionally manufactured by liquid-phase impregnation (LPI), in which the binder pitches and phenolic resins are impregnated into the composites, and by chemical vapor infiltration (CVI).

Machinability of 3D printed peek reinforced with short carbon fiber

open access: yes, 2023
The new manufacturing technologies are advancing and developing rapidly, gradually causing some conventional processes used until now to become obsolete or relegated to second place.

Linking neurogenesis, oligodendrogenesis, and myelination defects to neurodevelopmental disruption in primary mitochondrial disorders

open access: yesFEBS Letters, EarlyView.
Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

Carbon Fibers [PDF]

open access: yes, 2015
Remarkably, truly novel structures are still being found for materials made of a single element: carbon. Perhaps there is a ‘revolution’ in carbon-only materials. Indeed, recently, two Nobel prizes were awarded for new forms of carbon: for fullerenes in 1996, and for graphene in 2010.

Evolution of Frictional Wear Behavior of C/C-CuNi Composites by Arc Discharge

open access: yesLubricants
This study fabricated a C/C-CuNi composite using the hydrothermal co-deposition method and investigated its friction and wear behavior as well as the underlying mechanisms after being subjected to arc discharge ablation.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Tailoring ablation resistance of (Hf,Zr,Ta)C coatings above 2000 °C: Critical role of Ta content

open access: yesJournal of Advanced Ceramics
Multicomponent (Hf,Zr,Ta)C ceramics are promising candidates for ablation-resistant coating materials applied in ultrahigh-temperature environments. However, the influence of compositional variations on their ablation behavior remains insufficiently ...

Effect of Laser Deoxidation on Adhesive‐Bonded Aluminum in an Oxygen‐Free Atmosphere

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates laser ablation of aluminum under oxygen‐free conditions. The goal is to produce oxide‐free substrates that enable improved adhesive bonding with epoxy. Optimized laser parameters (90% overlap, 300 µJ) combined with oxide‐free substrates result in the highest tensile strength of the adhesive bond.

Andic oxidation of high-modulus carbon fibers in sulfuric acid under different electric fields

open access: yesCailiao gongcheng
The inert surface of high-modulus carbon fiber leads to the weak interface between it and the resin matrix, which limits the performance of high-modulus carbon fiber composite in many application scenarios.
