Catalyzed Microwave-Assisted Preparation of Carbon Quantum Dots from Lignocellulosic Residues

A lignocellulosic residue from the pulp and paper industry (primary sludge) was employed to obtain carbon-based fluorescent nanomaterials. The unprecedented preparation of the carbon quantum dots (CQDs) was carried out using a microwave-assisted reaction catalyzed by a solid acid catalyst, which induced the formation of CQDs. The obtained CDQs were fully characterized using a number of analytical techniques. HR-TEM images depicted particle sizes of average diameter value of 17.5 nm. UV–visible spectra displayed a characteristic peak at 325 nm associated with the formation of CQDs. Fluorescence measurements recorded at 360 nm (excitation wavelength) exhibited an emission band at ca. 435 nm. This emission signal turned out to be dependent on the excitation wavelength that further confirmed the presence of CQDs

Encapsulated Laccases as Effective Electrocatalysts for Oxygen Reduction Reactions

The efficient electronic wiring of silica-encapsulated laccases has been applied for the first time to the bioelectrocatalytic reduction of oxygen. The synthesized silica/laccase composites were evaluated electrochemically and characterized by UV–vis, Fourier transform infrared (FT-IR), dynamic light scattering, and X-ray photoelectron spectroscopy. FT-IR measurements showed that laccase preserved its native-like structure after the biosilicification process. The one-pot biosilicification synthesis facilitated the accommodation of the enzymes in highly effective orientations for the direct electron transfer of the T1 redox centers. Consequently, the biosilicified laccase deposited on Ni electrodes exhibited an efficient bioelectrocatalytic oxygen reduction, with current densities of up to 0.94 mA/cm²

FGL enhances spatial learning.

<p>(A) Mean distances swam to find the hidden platform in the Morris water maze are represented for control rats (white symbols) and FGL-treated rats (black symbols) over 2 training days (four trials each). <i>N</i>, number of animals. Statistical significance was analyzed with repeated-measures ANOVA. (B) Cumulative frequency distributions of the distances swam by individual rats. Each data point represents the distance swam by one rat in the last trial of each day.</p
