The degradation of residual pesticides and the quality of white clover silage are related to the types and initial concentrations of pesticides

Nippon Nōyaku Gakkaishi (2021)

Jianzhen Ge Wenhui Fu Magaweng Bai Lu Zhang Bolin Guo

In order to understand the degradation of different residual pesticides of white clover silage and their influence on silage quality, three commonly used orchard pesticides with different concentrations were added to the white clover and fermented for 90 days. The results showed that the degradation rate of cypermethrin and its toxic degradation product 3-phenoxybenzoic acid (3-PBA) was the highest after silage, at different concentrations, both were 100%. The degradation rate of Tebuconazole and chloropyridine was 72.47-80.27% and 47.76-64.82%, of which 3,5,6-trichloro-2-pyridinol (TCP) content, poisonous toxic degradation product, increased 0.0525-0.253 mg·kg

Ultrafast Thermodynamic Control for Stable and Efficient Mixed Halide Perovskite Nanocrystals

Advanced Functional Materials (2020)

Chao Luo Cheng Yan Wen Li Fengjun Chun Meilin Xie

Abstract Low photoluminescence quantum yield (PLQY) and spectra instability, the two most difficult challenges in blue‐emitting CsPbBr x Cl 3− x NCs, have not yet been solved. Quickly controlling the reaction thermodynamics is crucial to enhance crystallinity, thus PLQY and spectra stability, but it has been ignored until now. An ultrafast thermodynamic control (UTC) strategy is designed by utilizing liquid nitrogen to instantaneously freeze the superior crystal lattices of CsPbBr x Cl 3− x NCs formed at high temperature. The average cooling rate exhibits a 33‐fold increase compared to conventional ice‐water cooling (from 1.5 to 50 K s −1 ). This UTC can make the reaction thermodynamic energy of the system lower than the threshold very quickly. Therefore, abrupt termination of further crystal growth can be achieved, which also avoids additional nucleation at low temperature. With the assist of defect passivation, the final blue‐emitting CsPbBr x Cl 3− x NCs exhibit an absolute PLQY of 98%, representing the highest value in Pb‐based blue perovskites to date. More importantly, they exhibit superior spectra instability. This UTC strategy not only represents a new avenue to synthesize perovskite NCs with excellent crystal quality and ultrahigh PLQY, but also provides a good reference to deal with the recognized bottleneck of spectra instability.

The 1-Tosylpentan-3-one Protects against 6-Hydroxydopamine-Induced Neurotoxicity

International Journal of Molecular Sciences (2017)

Chien-Jen Kao Wu-Fu Chen Bolin Guo Chien‐Wei Feng Han-Chun Hung

Previous studies have demonstrated that the marine compound austrasulfone, isolated from the soft coral Cladiella australis, exerts a neuroprotective effect. The intermediate product in the synthesis of austrasulfone, dihydroaustrasulfone alcohol, attenuates several inflammatory responses. The present study uses in vitro and in vivo methods to investigate the neuroprotective effect of dihydroaustrasulfone alcohol-modified 1-tosylpentan-3-one (1T3O). Results from in vitro experiments show that 1T3O effectively inhibits 6-hydroxydopamine-induced (6-OHDA-induced) activation of both p38 mitogen-activated protein kinase (MAPK) and caspase-3 in SH-SY5Y cells; and enhances nuclear factor erythroid 2–related factor 2 (Nrf2) and heme oxygenase-1 (HO-1) expression via phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt) signaling. Hoechst staining and Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) staining results reveal that 1T3O significantly inhibits 6-OHDA-induced apoptosis. In addition, the addition of an Akt or HO-1 inhibitor decreases the protective effect of 1T3O. Thus, we hypothesize that the anti-apoptotic activity of 1T3O in neuronal cells is mediated through the regulation of the Akt and HO-1 signaling pathways. In vivo experiments show that 1T3O can reverse 6-OHDA-induced reduction in locomotor behavior ability in zebrafish larvae, and inhibit 6-OHDA-induced tumor necrosis factor-alpha (TNF-α) increase at the same time. According to our in vitro and in vivo results, we consider that 1T3O exerts its anti-apoptotic activities at SH-SY5Y cells after 6-OHDA challenges, probably via the regulation of anti-oxidative signaling pathways. Therefore, this compound may be a promising therapeutic agent for neurodegenerations.

Understanding Excitonic Behavior in Light Absorption and Recombination Process

The Journal of Physical Chemistry C (2020)

Bolin Guo Chao Luo Cheng Yan Bai Sun Wen Li

Understanding excitonic behavior in light absorption and recombination process is urgently needed to regulate luminescent properties of two-dimensional (2D) perovskite; however, such information is still unexplored. Here, first, we demonstrate that pure phenethylamine lead bromine (PEA2PbBr4) nanosheets (NSs) possess strong exciton absorption and emission spectrum with high exciton binding energy (up to 310 meV) and prove that free excitons (FEs) play a decisive role in the optical transition process. Then, we design Cd-doped PEA2PbBr4 NSs to induce self-trapped excitons (STEs). Doping with isoelectric Cd naturally induces an impurity-driven lattice distortion and a strong exciton–phonon coupling, resulting in the STEs broadband extrinsic luminescence spectra. Further, the corresponding exciton fluorescent components of FEs and STEs can be effectively distinguished from the emission spectrum through spectral line-shape analysis, revealing the synergistic effect of exciton states in the recombination process. Unambiguously, this work will provide a deeper understanding of the exciton behavior and look forward to regulating exciton composition to obtain ideal luminescence properties.

Efficient CO Oxidative Coupling to Dimethyl Oxalate over the Pd/Al₂O₃ Nanocatalyst with the Assistance of Co Doping

ChemistrySelect (2024)

Bing Li Jiaming Zhu Ziqing Huang Bingjiang Jia Bolin Guo

Abstract CO oxidative coupling to dimethyl oxalate (DMO) is an important approach for the product of ethylene glycol and CO elimination. In this work, the Co doped Pd/Al 2 O 3 nanocatalyst was highly effective for CO oxidative coupling and enhanced remarkably CO conversion and the formation of DMO. The maximum DMO STY reached 1082 g L −1 h −1 over the Pd/Al 2 O 3 @1/20Co catalyst at 130 °C for 2 h under the space velocity of 3000 h −1 , which is two times higher than that over the Pd/Al 2 O 3 catalyst. The Co modification and its influence on the structure of the Pd/Al 2 O 3 catalyst were also studied systematically by XRD, TEM, CO‐TPD, N 2 physical adsorption and XPS techniques. An appropriate Co doing was confirmed to promote distinctly the generation of smaller Pd particles and the adjustment of the adsorption or activation of CO over the catalyst. A positive interaction between Pd nanoparticles and the modulated support with Co doping was demonstrated and favored the enhanced activity of the catalyst for the reaction.
