Controlling Pesticide Loss through Nanonetworks

ACS Sustainable Chemistry & Engineering (2014)

Yubin Xiang Min Wang Xiao Sun Dongqing Cai Zhengyan Wu

This work describes the feasibility of using high-energy electron beam (HEEB)-modified natural nanoclay (attapulgite) as an effective matrix to control the loss of pesticides that tend to discharge into the environment through washing and leaching, which causes severe pollution to both soil and groundwater. After irradiation by HEEB and because of thermal, charge, and impact effects, the originally aggregated attapulgite could be dispersed and form nanoporous networks, which could be beneficial for the binding of pesticides onto attapulgite. A loss control pesticide (LCP) was obtained when such attapulgite was added to a traditional pesticide. This pesticide–attapulgite complex could be retained by the rough surface of crop leaves, which increases the adhesion of pesticides on crop leaves and reduces pesticide loss, so that sufficient pesticides are supplied and the pollution risk of the pesticide is substantially lowered.

Wood-derived freestanding integrated electrode with robust interface-coupling effect boosted bifunctionality for rechargeable zinc-air batteries

Green Energy & Environment (2023)

Benji Zhou Nengneng Xu Liangcai Wu Dongqing Cai Eileen Hao Yu

Fabricating non-noble metal-based carbon air electrodes with highly efficient bifunctionality is big challenge owing to the sluggish kinetics of oxygen reduction/evolution reaction (ORR/OER). The efficient cathode catalyst is urgently needed to further improve the performance of rechargeable zinc-air batteries. Herein, an activation-doping assisted interface modification strategy is demonstrated based on freestanding integrated carbon composite (CoNiLDH@NPC) composed of wood-based N and P doped active carbon (NPC) and CoNi layer double hydroxides (CoNiLDH). In the light of its large specific surface area and unique defective structure, CoNiLDH@NPC with strong interface-coupling effect in 2D-3D micro-nanostructure exhibits outstanding bifunctionality. Such carbon composites show half-wave potential of 0.85 V for ORR, overpotential of 320 mV with current density of 10 mA cm−2 for OER, and ultra-low gap of 0.70 V. Furthermore, highly-ordered open channels of wood provide enormous space to form abundant triple-phase boundary for accelerating the catalytic process. Consequently, zinc-air batteries using CoNiLDH@NPC show high power density (aqueous: 263 mW cm−2, quasi-solid-state: 65.8 mW cm−2) and long-term stability (aqueous: 500 h, quasi-solid-state: 120 h). This integrated protocol opens a new avenue for the rational design of efficient freestanding air electrode from biomass resources.

ZSWIM4 regulates early embryonic patterning and BMP signaling pathway by promoting nuclear Smad1 degradation

Research Square (Research Square) (2022)

Chengdong Wang Ziran Liu Yelin Zeng Liangji Zhou Qi Long

Abstract The dorsoventral gradient of BMP signaling plays an essential role in embryonic patterning. We found that Zinc Finger SWIM-Type Containing 4 ( zswim4 ) is expressed in the Spemann-Mangold organizer at the onset of Xenopus gastrulation and then enriched in the developing neuroectoderm at the mid-gastrula stages. Knockdown or knockout of zswim4 caused ventralization. Overexpression of zswim4 decreased, whereas knockdown of zswim4 increased, the expression levels of ventrolateral mesoderm marker genes. Mechanistically Zswim4 attenuates the BMP signal by decreasing the protein stability of Smad1 in the nucleus. Stable isotope labeling by amino acids in cell culture (SILAC) identifies Elongin B (ELOB) and Elongin C (ELOC) as the interaction partners of Zswim4. Indeed, Zswim4 forms a complex with the Cul2-RING ubiquitin ligase and ELOB and ELOC, promoting the ubiquitination and degradation of Smad1 in the nucleus. Our study identified a novel mechanism that restricts BMP signaling in the nucleus.

Reducing the pollution risk of pesticide using nano networks induced by irradiation and hydrothermal treatment

Journal of Environmental Science and Health Part B (2015)

Xiao Sun Zuojun Liu Guilong Zhang Guannan Qiu Naiqin Zhong

Traditional pesticides (TP) often do not adhere tightly to crop foliage. They can easily enter the surrounding environment through precipitation and volatilization. This can result in the pollution of the surrounding soil, water, and air. To reduce pesticide pollution, we developed a loss-control pesticide (LCP) by adding attapulgite with a nano networks structure fabricated using high energy electron beam (HEEB) irradiation and hydrothermal treatment to TP. HEEB irradiation effectively dispersed originally aggregated attapulgite through modified thermal, charge, and physical effects. Hydrothermal treatment further enhanced the dispersion of attapulgite to form nano porous networks via thermal and wet expansion effects, which are beneficial for pesticide binding. An LCP has improved retention on crop leaf surfaces. It has a higher adhesion capacity, reduced leaching and volatilization, and extended residual activity compared with the TP formulation. The treatment increases the residual activity of pesticides on crop foliage and decreases environmental pollution.

A Facile and Effective Approach to Fabricate Chitosan/Hydroxyapatite Nanocomposite Coating on the Surface of Wood from Chinese Glossy Privet

Journal of Nanoscience and Nanotechnology (2016)

Ning Wang Chuanjie Cai Junjie Cheng Shengli Li Dongqing Cai

A chitosan/hydroxyapatite nanocomposite coating was fabricated on the surface of wood from Chinese Glossy Privet (CGP) and could adhere compactly to the wood surface. Fourier transform infrared spectra analysis indicated that the interaction between chitosan and hydroxyapatite might exist. In addition, sodium bicarbonate was added into the nanocomposite during the preparation process making the boating porous in acidic surrounding through effervescence effect. Field emission scanning electron microscope characterizations showed the nanocomposite (M(CS):M(HA) = 1:1, with 30% NaHCO3) was optimal and such composite was stable, which was verified by thermal analysis and in vitro degradation study. This work could provide a facile and effective fabricating approach of biocompatible material which may have some potential applications as bone-repairing material.
