Microwave-assisted heating instead of conventional heating can reduce the extraction time of chitosan, thus reducing energy consumption. Therefore, it is a more efficient and environmentally friendly method (Mohammadi et al., 2023). 3.2. Chemical process Homogeneous oligosaccharide molecules obtained by ...
Solution crystallization techniques of hybrid lead halides for perovskite photovoltaics, while remaining the most common method for fabricating solar cells, are inevitably complicated by the formation of numerous intermediate solvates that predetermine the morphology and properties of the final perovskite light...
Also, the unit cell volume (V) is estimated by the following formula from the lattice constant (a) values:(3)V=a3 The X-ray density (dX) values are estimated by means of the cubic lattice coordination number (Z), Avogadro's number NA = 6.022 × 1023, and unit cell volume (V) fro...

To date, a number of water-triggered synthetic hybrid SMPs have been reported6–9, such as shape memory polyurethanes filled with cotton cellulose nanowhiskers, cupric sulphate pentahydrate, pyridine moieties, poly(vinyl alcohol) and chitosan with polyethylene glycol, respectively. Even more, co-block...

Mice that had Cal-27 tumors got various nano formula intratumoral injections to investigate therapeutic processes using therapeutic processes photoactivation in vivo. In order to activate endosomal escape, siRNA release, and 1O2 production, mice were exposed to a 980 or 808 nm NIR laser. Tumor ...
The average crystallite size of the Sb2S3 powder was calculated using the Gaussian fit of the main observed (022) plane according the well-known Scherrer's formula. D = 0.9λ∕βcosθ (2) where D is the crystallite size, λ is the wavelength of the X-ray, β is full ...
