In this communication, we report a general strategy for the production of carbon nanodots (CDs) by microwave irradiation amino acids in presence acid or alkali. The resultant CDs exhibit strong photoluminescence and intense chemiluminescence enhancement NaIO(4)-H(2)O(2) system.
Abstract Herein we report the study of electrochemiluminescence (ECL) generation by tris(2,2′‐bipyridyl)ruthenium (Ru(bpy) 3 2+ ) and five tertiary amine coreactants. The ECL distance lifetime coreactant radical cations were measured self‐interference spectroscopy. And reactivity coreactants was quantitatively evaluated in terms integrated intensity. By statistical analysis images single Ru(bpy) ‐labeled microbeads, propose that codetermine emission intensity thus sensitivity immunoassay....
Uniform and monodisperse CuO nanorods have been synthesized by directional aggregation crystallization of tiny nanoparticles generated from a solid−liquid arc discharge process under ambient conditions in the absence any surfactants. with sharp ends are formed via that involves rapid oxidation Cu nanoclusters, spontaneous nanoparticles, Ostawald ripening process. The oriented attachment contributed obviously to formation these kinds nanostructures. By choice suitable reducing agent prevent...
This paper presents an accurate analysis of (i) the electronic transition energies ${E}_{22}^{S}$ and ${E}_{11}^{M}$, (ii) radial breathing mode (RBM) frequencies ${\ensuremath{\omega}}_{\mathrm{RBM}}$, (iii) corresponding RBM intensities from 40 small-diameter single-wall carbon nanotubes (SWNTs) in diameter range $0.7<{d}_{t}<1.3\phantom{\rule{0.3em}{0ex}}\mathrm{nm}$. The $({E}_{ii})$ are initially considered nonorthogonal tight-binding total-energy calculations. To account for...
Using the extended tight-binding model that allows bond lengths and angles to vary, optical transition energies Eii in single-wall carbon nanotubes are calculated as a function of inverse tube diameter. After geometrical structure optimization, 2n+m=constant family behavior observed photoluminescence (PL) experiments is obtained, detailed agreement between calculations PL achieved after including many-body corrections.
An ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIM][BF4]) solution system has been designed for the morphogenesis and crystallization of Bi2S3 nanostructures at low temperature ambient atmosphere. Uniform flowers with a size 3−5 μm, which are composed nanowires diameter 60−80 nm, can be prepared in large scale by template effect solution, vesicles formed as confirmed laser light scattering (LLS) analysis. The formation mechanism proposed. With prolonged aging time,...
The global rise of antimicrobial resistance (AMR) that increasingly invalidates conventional antibiotics has become a huge threat to human health. Although nanosized antibacterial agents have been extensively explored, they cannot sufficiently discriminate between microbes and mammals, which necessitates the exploration other antibiotic-like candidates for clinical uses. Herein, two-dimensional boron nitride (BN) nanosheets are reported exhibit activity AMR bacteria. Interestingly, BN had...
Abstract While hypoxia promotes carcinogenesis, tumour aggressiveness, metastasis, and resistance to oncological treatments, the impacts of hyperoxia on tumours are rarely explored because providing a long-lasting oxygen supply in vivo is major challenge. Herein, we construct micro factories, namely, photosynthesis microcapsules (PMCs), by encapsulation acquired cyanobacteria upconversion nanoparticles alginate microcapsules. This system enables through conversion external radiation into...
The method for quantifying the amount of each carbon nanotube specie, as defined by its diameter and chiral angle, well semiconducting-to-metallic ratio in any type sample is discussed. Single-wall nanotubes grown cobalt-molybdenum catalyst based (CoMoCAT) process are characterized. found to be 11:1. A single semiconducting named (6,5) represents $2∕5$ sample, while most abundant metallic (7,4), which exhibits a similar (6,5).
Well-defined inorganic–organic hybrid semiconductor nanobelts (see Figure) are produced by large-scale solvothermal synthesis through tuning the composition of a ternary solution composed diethylenetriamine (DETA), hydrazine hydrate, and deionized water. A suitable amount hydrate is essential for formation elegant uniform [ZnSe](EDTA)0.5 nanobelts.
Abstract The Joint Automated Repository for Various Integrated Simulations (JARVIS) is an integrated infrastructure to accelerate materials discovery and design using density functional theory (DFT), classical force-fields (FF), machine learning (ML) techniques. JARVIS motivated by the Materials Genome Initiative (MGI) principles of developing open-access databases tools reduce cost development time discovery, optimization, deployment. major features are: JARVIS-DFT, JARVIS-FF, JARVIS-ML,...
The higher lying bright exciton energies $({E}_{11}^{M},{E}_{33}^{S},{E}_{44}^{S},{E}_{22}^{M},{E}_{55}^{S},{E}_{66}^{S},{E}_{33}^{M})$ of single-wall carbon nanotubes are calculated by solving the Bethe-Salpeter equation within an extended tight binding method. For smaller diameter nanotubes, some ${E}_{ii}$ excitonic states missing. In particular, ${E}_{ii}$'s on one-dimensional Brillouin zone (cutting line) no longer relevant to formation excitons and skipped in listing order values. Thus...
A new surface oxidation mechanism that enhances the luminescence of Au nanoclusters is discovered in synthesized with disulfide lipoic acid. The quantum efficiency increased from 1 to 2% up 10% upon sulfur at Au–ligand interface. Relatively low has been a bottleneck barrier exploit appealing near-infrared molecular-like gold for broader and effective applications. Combined IR, XPS, NMR analysis reveals outer atoms on ca. half acid ligands were partially oxidized accompanying enhancement....
Hydroxylation, an extensive post‐translational modification on proline, is critical for the modulation of protein structures, further dominating their functions in life systems. However, current mass spectrometry‐based identification, could hardly distinguish hydroxylation from neighboring oxidation due to same shifts, as well challenges posed by low abundance and exogenous during sample preparation. To address these, engineered nanopore was designed, capable discriminating single hydroxyl...

Conventional protein engineering methods for modifying nanopores are typically limited to 20 natural amino acids, which restrict the diversity of in structure and function. To enrich chemical environment inside nanopore, we employed genetic code expansion (GCE) technique site-specifically incorporate unnatural acid (UAA) into sensing region aerolysin nanopores. This approach leveraged efficient pyrrolysine-based aminoacyl-tRNA synthetase-tRNA pair a high yield pore-forming protein. Both...
