Tunneling microscopy and spectroscopy of multiwalled boron nitride nanotubes

, 2003
Atomic resolution images of multiwalled boron nitride nanotubes have been obtained using scanning tunneling microscopy operating at tunneling currents below 20 pA and biases of approximately –2.5 V.

Enhancing Blood Circulation With Epsilon‐Near‐Zero (ENZ) Materials via the Far‐Infrared Window of Human Skin

Advanced Science, EarlyView.
Epsilon‐near‐zero (ENZ) silicon carbide enables a selective far‐infrared emitter spectrally aligned with the human skin window around 10 µm for wavelength‐matched thermal therapy. In 25 within‐subject trials (50 hands) monitored by laser speckle contrast imaging, SiC increases blood perfusion by 30.2% versus a broadband graphite emitter while ...

Influence of carrier gas flow rate on carbon nanotubes growth by TCVD with Cu catalyst

Journal of Saudi Chemical Society, 2016
Carbon nanotubes (CNTs) were grown on copper catalyst by thermal chemical vapor deposition (TCVD) using H2 and N2 as carrier gases. CNTs with different morphologies were observed using different carrier gas flow rates.

Junction Physics and Architectural Paradigms in Optoelectronic Semiconductor Fibers

Advanced Science, EarlyView.
Optoelectronic fibers are emerging as a key platform for distributed sensing, energy harvesting, and optical communication in deformable systems. Their performance is fundamentally governed by junction formation under confined, dynamic processing conditions.

TDP‐43 Aggregation: The Healthy‐Toxic Balance of the Prion‐Like Domain

Advanced Science, EarlyView.
TDP‐43 function relies on a delicate balance between reversible phase‐separated states and irreversible aggregation. Under physiological conditions, TDP‐43 forms dynamic droplets and oligomers that support normal cellular functions. In pathological contexts, this balance shifts toward aberrant aggregation, leading to toxic species.

Miro1 Enhances Mitochondria Transfer from Multipotent Mesenchymal Stem Cells (MMSC) to Neural Cells and Improves the Efficacy of Cell Recovery

Molecules, 2018
A recently discovered key role of reactive oxygen species (ROS) in mitochondrial traffic has opened a wide alley for studying the interactions between cells, including stem cells. Since its discovery in 2006, intercellular mitochondria transport has been

CCT4 promotes tunneling nanotube formation

FEBS Letters
Tunneling nanotubes (TNTs) are membranous tunnel‐like structures that mediate cell‐to‐cell communication, although the molecular mechanisms of TNT formation are not fully understood. T‐complex protein 1 subunit delta (CCT4) serves as a component of the chaperonin‐containing TCP1 complex (TRiC) and also functions as a monomer.

Electronic spectra of commensurate and incommensurate DWNTs in parallel magnectic field

, 2009
We study the electronic spectra of commensurate and incommensurate double-wall carbon nanotubes (DWNTs) of finite length. The coupling between nanotube shells is taken into account as an inter-shell electron tunneling. Selection rules for the inter-shell
