Article Synopsis
  • Combined pollution from cadmium (Cd) and arsenic (As) poses risks to crop safety and human health, particularly in rice cultivation.
  • A study investigated the effects of a silicon-rich amendment (HA) made from rice husk on reducing the uptake of Cd and As in rice seedlings, showing that it enhanced growth and decreased metal concentrations in the plants.
  • Findings indicated that HA improved iron plaque composition in rice, leading to lower Cd absorption and higher As retention, making HA a promising eco-friendly solution for remediating contaminated paddy fields.

Surface modification is of critical interest to enhance boiling heat transfer in terms of heat transfer coefficient or critical heat flux (CHF), which is significantly affected by distinct surface morphology and wettability and it can improve the efficiency and safety of equipment. Furthermore, actual service environment may cause severe corrosion to the processed structured surfaces while its consequence on boiling heat transfer is still obscure. In this article, comprehensive researches are conducted to unravel corrosive effect on metallic samples made of stainless steel (SS) and Inconel materials with microstructures.

Antimicrobial peptides could inhibit the growth of harmful bacteria and promote the growth performance in weaned piglets. Here, we investigated the effects of dietary supplementation with cecropin antimicrobial peptides (CAP) on growth performance, diarrhea rate, intestinal health in nursery Hainan piglets. For this, 120 healthy nursery Hainan male piglets (13.

A rice pot experiment was conducted to identify the effect of silica fertilizer prepared from husk ash on the soil bioavailability of cadmium (Cd) and arsenic (As), enzyme activities, microbial community structure, and heavy metal content in brown rice at different growth stages. The results showed that the application of 0.1%-1.

This study was to investigate the effects of dietary supplementation with putrescine on the growth performance and meat quality of chickens. A total of 480 eighty-day-old female Wenchang chickens were randomly assigned into four groups, with 8 replications per group and 15 animals per replicate. The chickens in the control group (Con) were fed a basal diet; the 3 experimental groups were fed a basal diet with 0.

Article Synopsis
  • The study investigates how soil microorganisms respond to soils contaminated with both heavy metals and total petroleum hydrocarbons (TPH), revealing shifts in microbial communities under different types of pollution.
  • Heavy metal-TPH co-contaminated soils showed reduced microbial diversity, with significant increases in specific microbial groups like Proteobacteria in one sample (HT1) and Firmicutes in another (HT2), indicating different responses to varying pollutant compositions.
  • The research identifies potential bioremediation bacteria that could help clean up pollution, such as Streptococcus and Acinetobacter for heavy metals, and Syntrophaceae for TPH, providing new insights for future environmental cleanup efforts.

Being able to obtain various environmental and driving data from vehicles is becoming more and more important for current and future intelligent transportation systems (ITSs) to operate efficiently and economically. However, the limitations of privacy protection and security of the current ITSs are hindering users and vehicles from providing data. In this paper, we propose a new ITS architecture by using blockchain technology solving the privacy protection and security problems, and promoting users and vehicles to provide data to ITSs.

The effects of amendments, such as lime, bassanite, sodium phosphate, steel slag and charcoal, and their compounds on the immobilization of cadmium (Cd) are investigated. The lime-bassanite-charcoal compound shows the best remediation performance compared to other agents in conducted experiments. The optimum condition for lime-bassanite-charcoal application in contaminated soil is lime-bassanite-charcoal with a mass ratio of 1:1/3:2/3, a dose of 2% of the soil weight, and a liquid-to-solid ratio of 35%-40%; additionally, the agents should be added before water addition.

With the conflicting problems of pollution due to ammonia emissions and the demand for ammonia, we propose M-2(INA) (M=Cu, Co, Ni, Cd) (INA=isonicotinic acid), a series of materials that exhibit flexible conversion in ammonia adsorption. They can capture both wet and dry ammonia for recycling. The materials were obtained by dehydration of coordination materials M(INA)2(H2O)4 (M=Cu, Co, Ni, Cd) (150°C) at atmospheric pressure for 2h.
