We propose a new superhydrophobic surface that contains a carbon nanotube (CNT)-implanted poly(dimethylsiloxane) (PDMS)/adhesive multilayer. The adhesive provides very strong adhesion between the CNT-implanted PDMS layer and the substrate, and the CNTs on the surface exhibit superhydrophobicity. Therefore, the CNT-implanted PDMS/adhesive (CIPA) layer provides a highly reliable surface for superhydrophobicity.

However, because the needle tip is invisible during injection using the CT approach, precise localization requires a high level of experience, and mastering this approach involves a steep learning curve. To overcome current limitations, we conceptualized a novel technique: real-time light-guided VFI (RL-VFI), which enables simultaneous VFI under direct visualization of the lighted needle tip.

- - The eglC gene in Aspergillus nidulans, which is related to a beta-1,3-endoglucanase enzyme, shows a significant similarity to a similar enzyme found in yeast and its expression relies on the nsdD gene, a transcription factor.
- - Deleting the eglC gene does not impact growth or development rates in fungal cells, but makes the cell wall more resistant to certain enzymes, suggesting changes in its structure.
- - Other gene deletions, like fadA and sfaD, do not affect eglC expression, while deleting flbA reduces its transcript level; importantly, eglC is not impacted by carbon-catabolite repression.
