To detect POCl3 molecule, adsorption phenomena of this molecule on the pure, Al- and Si-doped BN sheet surfaces were investigated via density functional theory (DFT) approach. The most stable adsorption complexes, including POCl3/BN (O-B), POCl3/Al-BN (O-Al), and POCl3/Si-BN (O-Si), were predicted with the adsorption energies of about -8.64, -37.01 and, -62.01 kcal mol-1, respectively. Upon the...
Complex micro- and nano-structures enable crucial developments in the healthcare remit (e.g., pharmaceutical and biomaterial sciences). In recent times, several technologies have been developed and explored to address key healthcare challenges (e.g., advanced chemotherapy, biomedical diagnostics and tissue regeneration). Electrohydrodynamic atomization (EHDA) technologies are rapidly emerging a...
Dual nano-electrospray for probing solution interactions and fast reactions of complex biomolecules.
A novel nano-electrospray emitter has been developed containing two separated channels running throughout the length of the emitter. The emitters have been fabricated from "theta-shaped" borosilicate capillaries. Loading of different solutions into the two different channels opens up the possibility to study short timescale interactions within a Taylor cone common to both channels. The common ...
Axonal regeneration in the peripheral nervous system is greatly supported by Schwann cells (SCs). After nerve injury, SCs dedifferentiate to a progenitor-like state and efficiently guide axons to their original target tissues. Contact and soluble factors participate in the crosstalk between SCs and axons during axonal regeneration. Here we show that dedifferentiated SCs secrete nano-vesicles kn...
The stability of hydrophobic surface has an important influence on the application superhydrophobic function. destruction micro-nano structures material is main factor leading to loss property. In order improve corrosion resistance surface, Ni-Co-BN nanocomposite coatings with property were prepared 45 steel by two-step jet electrodeposition. morphology, water contact angle, and samples measure...
Cubic boron nitride (c-BN) nucleation takes place on hexagonal boron nitride (h-BN) layers growing perpendicular to the substrate surface during thin film synthesis. Studies focused on the nucleation of the cubic phase suggest the possibility that transient phases and/or defects on these h-BN structures have a role in sp3-bonded cubic phase nucleation. In this study, we have investigated the na...
Hybrid structures of few or single quantum dots (QDs) coupled to single optical antennas are of prime interest for nano-optical research. The photoluminescence (PL) signal from single nanoemitters, such as QDs, can be enhanced, and their emission characteristics modified, by coupling them to plasmonic nanostructures. Here, a self-aligned technique for placing nanoscale QDs with about 10 nm late...
