With the increasing likelihood of significant release of engineered nanomaterials (ENMs) into the environment, investigations focused on the behavior and impact of ENMs on plant species which have become more important and prevalent. One consistent challenge in these studies is how to separate t...

Quaternary ammonium hydroxide (QAH) solution has been used to dissolve cellulose and made great progress in recent years. While, its cellulose dissolution mechanism is still in unclear. Here, series of QAH with varied cationic alkyl chains were chosen for the investigation. The solubility of cel...

An experimental study was conducted to investigate the performance characteristics of spray cooling with ammonium hydroxide (NH4OH) binary mixture for high heat flux removal. Two mixtures, having ammonia mass fractions of 0.3 and 0.5, were selected to represent practical operation conditions nea...

Tetracycline (TC) is a widely used antibiotic. Ferrihydrite and goethite are representative of amorphous and crystalline iron oxide minerals (IOMs). In this paper, the mechanisms underlying the interactions between TC and two typical IOMs were delineated. Both IOMs had specific adsorption, and f...

Antibiotics are extremely effective against bacterial infections due to their selective toxicity for bacteria rather than the host. Extensive use and misuse of antibiotics resulted in significant increases in antibiotic levels in aquatic and soil environments. Bacteria exposed to antibiotics wit...

Tetracyclines are a class of antimicrobials frequently found in the environment, and have promoted the proliferation of antibiotic resistance. An unanswered research question is whether tetracycline sorbed to soils is still bioavailable to bacteria and exerts selective pressure on the bacterial ...

To control food safety, protect human safety and health, sensors for tetracycline antibiotics with easy operation, in-situ applications, high sensitivity and selectivity have been urgently needed. In this review, we provide an overview of recent advances and new trends in sensors for the detecti...

BackgroundIncreasing resistance in bacteria towards antibiotics has made it imperative to research on their revitalization to combat infectious diseases. This study dealt with synthesis of a nano-form of the antibiotic tetracycline, its characterization and potency of killing different multi-dru...

The release of pharmaceuticals into aquatic environments is a serious concern due to the persistence and potential health and environmental risks of these substances. Surface and ground waters are polluted with a variety of pharmaceuticals due to insufficient water purification processes in wast...

In this study, montmorillonite nanosheets were used in order to control the release pattern of tetracycline based on the pH and to control its antimicrobial activity upon release. The tetracycline was adsorbed onto the montmorillonite nanosheets based on cation exchange mechanism and a pH-respon...

Exposure to tetracycline in soil causes microbial mutations. Soil microbial fuel cells (MFCs) can promote the degradation efficiency of contaminants while generating bioelectricity under anaerobic conditions. MFC performance varies amongst different types of soils due to distinctive soil propert...

Tetracyclines belong to the group of the most applied antibiotics in veterinary medicine worldwide. Due to their incomplete absorption and/or metabolism in the animal gut, tetracyclines are frequently detected in manure samples. Within the matrix, an elimination of these compounds has been repor...

Antibiotics represent a novel type of environment pollutants which modify chlorophyll content in plants. Spectroscopic methods were employed to investigate the effect of tetracycline on chlorophyll degradation. Changes in absorbance and fluorescence demonstrated that tetracycline reaction with c...

Catalysts composed of copper supported on ZnAl2O4 were prepared by conventional impregnation of a commercial zinc aluminate powder using copper nitrate water solutions. The fresh catalysts were characterized by XRD, skeletal IR and DR-UV–vis spectroscopies, FE-SEM microscopy, BET and pore volum...

In light of the growing interest and ability to search for new materials, we have synthesized Nickel oxide (NiO) nanoparticles decorated Zinc (ZnO) nanorods composite (NiO/ZnO) nanostructure. The NiO/ZnO heterostructure formation was confirmed by X-ray powder diffraction and high-resolution tran...

The long-term supply sustainability of copper, zinc and lead was assessed. Copper will not run into physcal scarcity in the future, but increased demand and decreased resource quality will cause significant price increases. The copper price is suggested to increase significantly in the coming de...

Metals are involved in different pathophysiological mechanisms associated with neurodegenerative diseases (NDDs), including Alzheimer’s disease (AD), Parkinson’s disease (PD) and multiple sclerosis (MS). The aim of this study was to review the effects of the essential metals zinc (Zn), copper ...

Construction and demolition (C&D) wood can be recycled as mulch for landscaping or cogeneration. Limitations to such recycling are dependent on metals concentrations in mulch (As, Cu, and Cr) from the inclusion of waterborne-preservative treated wood. The objective of this study was to evaluate ...

Hydrometallurgical removal of heavy metals (like chromium, iron, and zinc) from an industrial effluent, and their valorization into less-toxic species has been studied. At first, the solvent extraction of Cr(VI) was investigated with tri-butyl phosphate (TBP) to separate this carcinogenic metal ...

SummaryBackgroundThe present study has the objective to assess the zinc (Zn), copper (Cu), and oxysterols plasma levels in type 1 (DM1) (n=26) and type 2 (DM2) (n=80) diabetes patients, as compared to healthy controls (n=71), in order to testify whether metal levels may have a significant impact...
