Abstract Many species of fungi naturally produce light, a phenomenon known as bioluminescence, however, the fungal substrates used in chemical reactions that light have not been reported. We identified compound luciferin 3‐hydroxyhispidin, which is biosynthesized by oxidation precursor hispidin, and plant secondary metabolite. The does share structural similarity with other eight luciferins. Furthermore, it was shown 3‐hydroxyhispidin leads to bioluminescence extracts from four diverse...
Abstract Detonation nanodiamonds (NDs) were deposited on the surface of aligned carbon nanotubes (CNTs) by immersing a CNT array in an aqueous suspension NDs dimethylsulfoxide (DMSO). The structure and electronic state obtained CNT–ND hybrid material studied using optical electron microscopy Infrared, Raman, X-ray photoelectron near-edge absorption fine spectroscopy. A non-covalent interaction between preservation vertical orientation CNTs revealed. We showed that current-voltage...
The particle size is one of critical parameters influencing the biodistribution detonation nanodiamonds (DND) after their administration into body. As DNDs are prone to aggregation, difference between sizes in aqueous and physiological solutions has be taken account. Radioactive I125-BSA molecules were covalently immobilized on divided three fractions different average size. DND-BSAI125 conjugates intravenously administrated adult mice allocation animal's organs blood was evaluated based...
The antiwear performance of the modified nanodiamond (ND) as an additive to commercial oils was studied. surface modification and ultrasonic treatment allow introduction ND into without significant agglomeration. in displayed a high colloidal stability for prolonged times. Two fractions with average particle sizes 96 270 nm were used. A block-on-ring test setup used investigate wear reduction capability additives at various load conditions friction pairs. results showed that 0.01 wt%...

We report on the optical limiting (OL) in stable aqueous suspensions of detonation nanodiamond (ND) clusters with average size 50, 110, and 320 nm. The nanosecond Z-scan measurements at wavelength 532 nm revealed that larger cluster size, better OL performance higher ray stability ND suspension. Our analysis showed nonlinear scattering absorption are dominant mechanisms suspensions.
A focused He – Ne laser beam is shown to cause local blackening of semitransparent detonation nanodiamond (DND) films at incident power densities above 600 W cm-2. Data obtained with a Raman spectrometer and low-power 632.8-nm source indicate that the accompanied by decrease in broadband background luminescence emergence sharp peaks corresponding structures sp2 carbon. The feasibility image recording on DND demonstrated.
Canine parvovirus (CPV) is now recognized as a serious threat to the dog breeding industry worldwide. Currently used CPV vaccines all have their specific drawbacks, prompting search for alternative safe and effective vaccination strategies such subunit vaccine. VP2 protein major antigen targeted developing vaccine, however, its production in baculovirus expression system remains challenging due insufficient yield. Therefore, our study aims increase by using an improved evaluate...
AbstractDetonation nanodiamond powders produced by different manufacturers were surface modified to reduce the amount of impurities and impart particles a high colloidal stability in aqueous suspensions. Modified DNDs (MDNDs) separated into fractions evaluated zeta potential, size distribution elemental composition. MDNDs retain after hydrosols are dried resulting resuspended. Sedimentation fraction composition proposed as parameters for standardization commercial nanodiamonds.Keywords:...
The regiospecificity of hydroxylation C2-halogenated phenols by Rhodococcus opacus 1G was investigated. Oxidative defluorination at the C2 position ortho with respect to hydroxyl moiety preferred over non-fluorinated C6 for all 2-fluorophenol compounds studied. Initial 2,3,5-trichlorophenol resulted in exclusive formation 3,5-dichlorocatechol. These results indicate that, contrast other phenol ortho-hydroxylases studied so far, hydroxylase from R. is capable catalyzing preferential oxidative...
