In this work, phosphorus-doped graphene quantum dots (P-GQDs) with a high phosphorus doping content (>7 at%) are synthesized <italic>via</italic> an electrochemical approach.
Three different carbon dots with high quantum yields were prepared via microwave method within 2 min. The hydroquinone-derived CDs could easily penetrate cells in 30
The synthesis of the bulky divalent (polyphenylcyclopentadienyl)lanthanoid sandwich complexes [Ln(C5Ph5)2] (Ln = Sm, Eu) and [Ln(C5Ph4H)2(solv)] solv thf; Ln Eu, dme)], from redox-transmetalation/protolysis (RTP) reactions, has been achieved. An analogous reaction with Yb afforded solvent-separated ion pair [Yb(dme)4][C5Ph4H]2. In addition, rare samarium halide [Sm(C5Ph5)(μ-Br)(thf)2]2 [Sm(C5Ph4H)I(thf)3], were also prepared, either by RTP or ligand rearrangement. X-ray studies showed that...
Doping carbon dots with nitrogen atoms considerably enhances their fluorescence properties. However, the mechanism by which are doped is not fully understood. We developed a facile bottom-up hydrothermal carbonization (HTC) process that uses glucose and glycine as precursors for synthesis of photoluminescent nitrogen-doped dots. The as-prepared were mono-dispersed spherical particles diameter -2.8 nm. assumed pyridinic type pyrrolic configurations to participate in nanocrystal structure It...
A Ag–graphene quantum dots (GQDs)–ZnO ternary photocatalyst was prepared using GQDs as both a reducing agent and cation solvent. Photodegradation performance improved because of the synergic effect Ag GQDs.
In this work, we develop a facile one-step strategy for rapidly (within 1 min) preparing four kinds of nitrogen doped carbon dots (N-CDs) and construct label free sensor array protein discrimination. The monodispersed blue emitting N-CDs, with quantum yield (QY) about 7.6% (calibrated quinine sulfate as the reference), were systematically characterized by using fluorescence spectroscopy, atomic force microscopy (AFM), dynamic light scattering (DLS), X-ray photoelectron spectroscopy (XPS)...
The performance state of lithium-ion batteries directly impacts the stability energy storage system operations. With prolonged use, undergo complex electrochemical changes, leading to capacity degradation and reduced performance. To accurately estimate health (SOH) for in application scenarios, this study conducts aging tests on under different charging voltages develops an online model-based SOH estimation method. First, excitation response analysis extended Kalman filter algorithm are used...
This work prepared three kinds of CDs with blue, yellow and red emissions further in-depth investigated their luminescence mechanisms through theoretical calculations together experimental data. Afterwards, a sensor array by using these for fast discriminating different types sulfur-containing species was constructed.
CQDs are separated on a C18 column by binary gradient elution <italic>via</italic> HPLC.
The Atherton-Todd-type reaction of pentacoordinate hydrospirophosphoranes with amines was investigated, and a novel CO2 insertion into the P-N bond under mild conditions developed. mechanism stereochemistry between secondary were proposed via carbon-13 labeling experiment, (31)P NMR tracing X-ray diffraction analysis. chlorinated spirophosphorane intermediate first generated stereoretention configuration at phosphorus subsequently attacked by carbamate anion formed from amine. It found that...
Nowadays, tissue engineering vascularisation has become an important means of organ repair and treatment major traumatic diseases. Vascular endothelial layer regeneration functionalisation are prerequisites components vascularisation. The present researches mainly focus on scaffold preparation implant surface modification. Few studies have reported the interaction scaled materials, especially nanomaterials. Magnesium (Mg), as essential cytotropic active element in human body, should promote...
GQDs surface modified ZnO + Cu heterostructure photocatalysts was prepared <italic>via</italic> a simple spin-coating and annealing process, which exhibits enhanced photocatalytic performance.
