Carbon Fiber from Direct Carbonization of Pedot:Pss Precursor Fibers

Carbon Trends
An important factor limiting widespread carbon fiber utilization is the immense energy required for its manufacture. Specifically, the pre-carbonization stabilization processing step required for polyacrylonitrile and pitch fiber precursors accounts for a large portion of the total processing time and embodied energy associated with carbon fiber ...

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

FEBS 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.

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

Molecular 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

Journal 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 ...

Wide-Range Tunable Dynamic Property of Carbon Nanotube-Based Fibers

, 2015
Carbon nanotube (CNT) fiber is formed by assembling millions of individual tubes. The assembly feature provides the fiber with rich interface structures and thus various ways of energy dissipation, as reflected by the non-zero loss tangent (>0.028--0.045)

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials

Advanced Engineering Materials, EarlyView.
Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting
