The fluorescent N-doped carbon dots (N-CDs) obtained from C3N4 emit strong blue fluorescence, which is stable with different ionic strengths and time. fluorescence intensity of N-CDs decreases the temperature increasing, while it can recover to initial one decreasing. It an accurate linear response temperature, may be attributed synergistic effect abundant oxygen-containing functional groups hydrogen bonds. Further experiments also demonstrate that serve as effective in vitro vivo...

A combustion flame method is developed for the convenient and scalable fabrication of single- dual-doped carbon quantum dots (CQDs) (N-CQDs, B-CQDs, P-CQDs, S-CQDs B,N-CQDs, P,N-CQDs, S,N-CQDs), doping contents can be easily adjusted by simply changing concentrations precursors in ethanol. These single/dual-doped CQDs, especially show high catalytic activities oxygen reduction reaction.

Developing light-driven acid catalyst will be very meaningful for the controlled-acid catalytic processes towards a green chemical industry. Here, based on scanning electrochemical microscopy (SECM) and ΔpH testing, we demonstrate that 5–10 nm carbon quantum dots (CQDs) synthesized by ablation of graphite have strong light-induced proton properties under visible light in solution, which can used as an catalyst. The CQDs' activity is strongly dependent illumination intensity temperature...

Carbon dots (CDs) were synthesized by refluxing glucose, as efficient fluorescence probes, which show convenient and sensitive detection of norfloxacin (NOR) over a wide concentration range. It is worth noting that because the hydrogen bond interactions between CDs NOR, intensity was remarkably enhanced in presence indicates are capable rapid, stable determination NOR. Compared with high-performance liquid chromatography, enhancement method considerably simpler faster, will pave new way for

Future energy systems with a large share of fluctuating renewable energies demand thermal storages that are flexible and reliable. Sodium acetate trihydrate (SAT) has been investigated for many years as heat storage materials but the focus investigations were mostly on short-term applications. SAT high density supercooling degree which make it an ideal material. Heat utilizing stable can store almost loss free in both long-term, offers great benefits system. A review is presented this...

Abstract Dual‐active‐sites atomically coupled on ultrafine 1D nanowires (NWs) can offer synergic atomic heterojunctions (AHJs) and high atomic‐utilization toward multipurpose superior catalysis. Here, ≈2‐nm‐thick PtIr/IrO x hybrid NWs are elaborately synthesized with equilibrated Pt/IrO AHJs as high‐efficiency bifunctional electrocatalysts for overall water splitting. Mechanism studies reveal the Pt–IrO dual‐sites favorable facilitating dissociation, alleviating binding of H* Pt sites...

Global warming has heightened the severity and frequency of extreme high-temperature events, presenting challenges to fish survival negatively affecting production fishery. Gymnocypris eckloni, native Tibetan Plateau, is widely cultured in southwest China. Its sensitivity heat makes it a suitable model for studying impact high temperatures on fish. The heart vital organ survival, while relatively understudied concerning hearts. In this study, G. eckloni was subjected seven-day exposure 27 °C...

The interaction between carbon quantum dots (CQDs) and a single living cell was explored in real time. Here, we provide the quantitative data on permeability of HeLa membrane presence CQDs with different surface functional groups (CQDs terminated –OH/–COOH (CQD–OH), –PEG (CQD–PEG), –NH2 (CQD–NH2)). Although these have very low toxicity towards cells, they still increase by 8%, 13%, 19% for CQD–PEG, CQD–OH, CQD–NH2, respectively, this kind irreversible. These observations are valuable...

Carbon dots (CDs) with abundant functional groups (–OH, –COOH, CO) on their surface were specially designed to enhance the adsorption capacity and catalytic activity of gold nanoparticles (AuNPs). The CDs stabilized (AuNPs-CDs) greenly synthesized by a one-step reduction HAuCl4 which used as both reductant stabilizer under visible light irradiation. resulting AuNPs-CDs exhibit high towards 4-nitrophenol, good linear correlation ln(Ci/C0) versus time kinetic rate constant about 0.68 min−1....
