Surface-enhanced Raman scattering (SERS) signals strongly rely on the interactions and distance between analyte molecules metallic nanostructures. In this work, use of a gold nanoparticle (AuNP)-embedded metal–organic framework was introduced for highly sensitive SERS detection. The AuNPs were in situ grown encapsulated within host matrix MIL-101 by solution impregnation strategy. as-synthesized AuNPs/MIL-101 nanocomposites combined localized surface plasmon resonance properties...
Accurate and rapid differentiation authentication of agricultural products based on their origin quality are crucial to ensuring food safety control. However, similar chemical compositions complex matrices often hinder precise identification, particularly for adulterated samples. Herein, we propose a novel method combining multiplex surface-enhanced Raman scattering (SERS) fingerprinting with one-dimensional convolutional neural network (1D-CNN), which enables the effective category, origin,...
Abstract The present study deals with the theoretical investigation of mechanistic and regiochemical aspects Pd(II)‐catalyzed dehydrogenative Heck olefination selenophenes. detailed reaction mechanism was established, roles catalyst regioselectivity were well rationalized. Our results clearly showed that whole involves a concerted metalation‐deprotonation (CMD) process between C 2 site selenophene Pd(OAc) in first catalytic cycle. Afterward, olefin coordinates to palladium, followed by...
A novel method for highly selective recognition of UO22+ is proposed based on a [Eu(pyridine-2,5-dicarboxylic acid N-oxide)] (Eu-PDA) metal-organic framework. Benefiting from the unique chemical structure Eu-PDA, energy transfer PDA to was enabled, resulting in up-regulated fluorescence UO22+. The Eu-PDA probe showed excellent specificity over numerous interfering species, as intrinsic emissions were triggered.
Accurate determination of Ag+ released by silver nanoparticles (AgNPs) is vital for elucidating the environmental behaviors and defining exposure risks nanosilver. However, this remains challenging due to limitations in...
A series of new D–A−π–A indoline-based metal-free dyes, which are derived from the reported dye WS-9, have been designed and characterized theoretically for application in future dye-sensitized solar cells (DSSCs). The absorption, light harvesting efficiency, kinetics charge injection, recombination all chromophores systematically investigated via first-principles calculations. We find that featuring quinoxaline auxiliary acceptor instead benzothiadiazole modification on −A (2-cyanoacrylic...
A novel porous Au@MIL-100 (Fe) core-shell structure in which a Au nanoparticle (AuNP) core is coated with controllable uniform metal-organic framework shell has been fabricated by using facile step-by-step procedure. The as-synthesized takes advantage of the high adsorption capability MIL-100 and localized surface plasmon resonance properties AuNP core, was used as hybrid enhanced Raman scattering (SERS) substrate. We discussed fabrication, physical characterization, SERS activity our...
Blown films of poly(lactic acid) (PLA)/poly(butylene adipate‐co‐terephthalate) (PBAT) blends were prepared, bis(tert‐butyl dioxy isopropyl) benzene (BIBP) as crosslinking agent. From wide‐angle X‐ray diffraction results, PLA/PBAT/BIBP involved all the peaks consistent with PLA and PBAT. For DSC curves films, there two glass transition temperature melt temperature, existed step decomposition in thermogravimetric curves. Both Han plots Cole–Cole indicated high homogeneity 40/60/0.1 blend. SEM...
To study the effects of zirconium (Zr) addition on microstructure, hardness and tensile properties oxide dispersion strengthened (ODS) ferritic–martensitic steels, two kinds 9Cr-ODS steels with nominal compositions (wt.%) Fe-9Cr-2W-0.3Y2O3 Fe-9Cr-2W-0.3Zr-0.3Y2O3 were fabricated by mechanical alloying (MA) premixed powders then consolidated hot isostatic pressing (HIP) techniques. The experimental results showed that average grain size decreases Zr addition. trigonal δ-phase Y4Zr3O12 oxides...
