Although green finance policy is essential for sustainable development, its impact on green development is often underestimated. Using city-level data in China from 2009 to 2022, this study identifies the causal effect of green finance policy on green total factor productivity (GTFP) through an improved synthetic control method. The findings are as follows: First, green finance positively influences GTFP growth, and this effect increases over time.

The effectiveness of this method relies on the deposition and distribution of the spray droplets within the targeted application area. There is a critical need for an accurate and stable detection algorithm to evaluate the liquid droplet deposition parameters on the water-sensitive paper (WSP) and reduce the impact of image noise.

However, the effects of specific adjuvants on pesticide characteristics and the mechanism of action remain unclear. Herein, we analyzed the effects of three different types of tank-mix adjuvants (plant oil; mineral oil; and mixture of alcohol and ester) on the surface tension (ST), contact angle, wetting, permeation, evaporation, spray performance, and aphid-control effects of two types of pesticides.

Improving the pesticide efficiency of UAV spraying is a major challenge for researchers. One of the factors that affect the efficiency is the wetting property of the spraying solutions on crop leaves.

A self-cleaning nanoliquid (SN) was combined with microstructured Ag-dispersed CuZnPb (MAC) to realize good hydrophobicity functions of the SNMAC. This was because the cooperative functions of silver and the SN enhanced the water reunion ability and increased solid-liquid-gas contact areas, leading to high contact angles of SNMAC.

Droplet distribution characteristics of UAV spraying in the cotton canopy have notable effect on the biological control efficacy of the targets and the defoliation efficiency of the harvest aids. In this work, the influences on droplet distribution in the cotton canopy with respect to the flight height, forward mode, and spraying volume were evaluated by conducting the field trials during two cotton growth stages in 2020, respectively.

Dental implant is an advanced prosthodontic treatment widely accepted by patients with missing tooth. However, peri-implant bone loss is still an important reason which limits wider application of the implants to a certain extent. Bisphosphonates is an osteoclastic bone resorption inhibitor that is widely used in clinical practice with the function of inhibiting bone resorption and increasing bone density.

Objective: To develop zoledronic acid (ZA)-loaded collagen membranes, and to study its effect on osteoclast and osteoblast so as to investigate whether ZA-loaded membranes can inhibit local bone resorption and promote bone formation.
Methods: ZA-loaded double-layer (Bio-Gide(®)) and single-layer (BME-10X(®)) collagen membranes were prepared and divided into eight groups according to the concentrations of ZA in the membrane, namely Group BG0, BG1, BG2, BG3 and BM0, BM1, BM2, BM3 (BG refers to Bio-Gide(®), BM refers to BME-10X(®), 0, 1, 2, 3 refer to the concentrations of ZA, 0, 1 × 10(-4), 1 × 10(-3), 1 × 10(-2) mol/L respectively). Blank control group was set without using collagen membrane.

Objective: To develop a new local delivery system, osteoclastic-inhibitor-loaded collagen membrane, and to evaluate its drug loading and drug release properties.
Methods: Efforts were made to develop the drug-loaded membranes by combining two commercially available collagen barrier membranes (Bio-Gide and BME-10X) with zoledronic acid (ZA). The physicochemical and pharmacological properties of resulting materials were determined using SEM, EDS, FTIR, and HPLC.
