A novel worm‐like nickel‐titanium oxide nanocomposites coating was directly grown on a nickel‐titanium alloy wire by low‐voltage electrochemical anodization in alkaline ethylene glycol and water solution. The in situ growth of nickel‐titanium oxide nanocomposites greatly depended on the volume ratio of ethylene glycol to water and temperature.

The Contamination agricultural soils and food by cadmium(cd) is one of the major concerns of the world. The field experiments were conducted to investigate the effects of silicon (Si) fertilizer on bioavailability and accumulation of Cd in soil, Cd chemical fractions, dynamic changes of soil pH, available Cd content and Cd content of various parts of rice plants.

Platinum group metals (PGMs) are widely applied in the field of catalysts due to their excellent catalyst activity and high-temperature stability. The rapid generation of the waste catalyst has become the significant characteristic of PGMs with the accelerating consumption of limited PGMs nature resources. It is necessary to recover/recycle PGMs from a waste catalyst for both economic and environmental benefits.

An ultrahigh-performance liquid chromatography–tandem mass spectrometry (UPLC–MS/MS) method was established for the determination of four highly polar agricultural antibiotics kasugamycin, validamycin A, ningnanmycin, and polyoxin B in plant-derived foods. The samples were extracted with a 0.2% formic acid solution, purified by hydrophilic–lipophilic balance and mixed-mode cation-exchange solid-phase extraction, and then reconstituted for UPLC–MS/MS detection.

The present study describes using molecularly imprinted polymer (MIP) technology for determination of patulin (PAT) and 5-hydroxymethylfurfural (5-HMF) in beverages by ultra-high performance liquid chromatography coupled to photodiode array (UPLC-PDA). PAT (4-hydroxy-4H-furo[3,2-c]pyran-2(6H)-one) is a mycotoxin produced by Penicillium fungi and Penicillium expansum is probably the most commonly encountered species that infects apples during their growth, harvest, storage or processing.

This study aims to investigate the formation mechanism of 5-hydroxymethylfurfural and acrylamide in sesame seeds during roasting. Sesame seeds were roasted at 180, 200, and 220 °C for different time intervals, and changes in the concentration of sucrose, free amino acids, asparagine, 3-deoxyglucosone, 5-hydroxymethylfurfural, and acrylamide were monitored.

The aroma-active compounds of three Xi baijiu samples (Xijiulan, Y1, Xijiuyinxiangguizhou, Y2 and Xijiuyinzhi, Y3) were analyzed by gas chromatography–olfactometry (GC–O), GC–flame photometric detection (FPD) and odor activity value (OAV). The results indicated that a total of 92 aroma compounds were determined, including 16 sulfur compounds.

In this study, a practical and excellent method was used to determine the famoxadone and cymoxanil via high-performance liquid chromatography equipped utilizing ultraviolet detector lamp (HPLC-UV) for investigating the dissipation behavior and residue distribution of famoxadone and cymoxanil in cucumber and soil ecosystem. The limit of quantification (LOQS) of famoxadone and cymoxanil in cucumber were 0.50, 1.00, 2.00 and 0.05, 0.50, 1.00 mg kg−1 in soil, respectively.

Screening of terpenoids from Azadirachta indica against the Akt showed they are potent inhibitors of the protein. The screening revealed lupeol, a triterpenoid as the lead compound. Lupeol demonstrate surpassing inhibitory potential on Akt 2 than ipatasertib in in‐silico studies Terpenoids extract downregulate Akt mRNA and demonstrated anti‐Akt downstream signaling effects; anti‐inflammatory, anti‐angiogenesis, pro‐apoptotic, and cell cycle arrest.

Biochar has various ecological effects on heavy‐metal‐contaminated soils. Biochar can passivate the activity of heavy metals and improve environmental conditions for microbial growth. A greenhouse pot experiment was conducted to explore the diversity of microbes in red soil under cadmium (Cd) stress following the application of wheat straw biochar.

Organochlorine pesticides (OCPs), chemicals frequently used in agriculture, are a group of highly toxic and persistent organic pollutants. This study assesses the distribution and congener profiles of residual OCPs in 11 types of vegetable oils collected from Chinese markets. All samples were extracted using the modified QuEChERS method prior to analysis by gas chromatography–triple quadrupole mass spectrometry.

Food can contain unwanted compounds and need to be analyzed for compounds like carcinogenic polycyclic aromatic hydrocarbons to ensure consumer safety. The analytes need to be extracted from the sample matrix and cleaned‐up to enable detection. However, established methods for clean‐up are labor‐intensive and have a high expenditure on organic solvents.

Food is the major cadmium (Cd)-exposure pathway from agricultural soils to humans and other living entities and must be reduced in an effective way. A plant can select beneficial microbes, like plant-growth-promoting rhizobacteria (PGPR), depending upon the nature of root exudates in the rhizosphere, for its own benefits, such as plant growth promotion as well as protection from metal toxicity.
