Correction: Integrated water quality dynamics in Wadi Hanifah: Physical, chemical, and biological perspectives.

The Wadi Hanifah, a crucial aquatic ecosystem, has unfavorable consequences from natural occurrences and human activities. Recognizing the critical need for sustainable water management, this study provides an in-depth evaluation of wadi water quality. A comprehensive assessment was conducted, analyzing physical properties (temperature, pH, electrical conductivity, turbidity, color, and odor), chemical constituents (nitrogen compounds, ion concentrations, heavy metals), and bacterial diversity. The study found significant temperature fluctuations, particularly in sun-exposed or stagnant water areas. The water exhibited slight alkalinity and variable electrical conductivity and turbidity, indicating differing pollution levels. High ammonia and heavy metal concentrations suggested organic and industrial contamination, respectively. In addition, the prevalent fecal-indicator bacteria pointed to possible sewage or agricultural runoff. The research highlights the complex interplay of natural and anthropogenic factors affecting Wadi Hanifah's water quality. It emphasizes the need for location-specific environmental management strategies focusing on pollution control and conservation to safeguard the wadi's ecological health. This study provides vital insights for effective water resource management in Wadi Hanifah, serving as a model for similar ecosystems.

In modern science and technology, it is often underappreciated that foods from a chemical, physical and biological perspective are complex multifactorial systems that are extremely difficult to measure and evaluate. From a chemical perspective, foods are complex chemical mixtures of heterogeneous classes of molecules dominated by the four basic food constituents: water, fats, carbohydrates and proteins. To add further complexity, food manufacturing processes often consists of a series of unit operations that are designed to induce certain functional traits to the food materials being processed. This chapter will seek to give an overview of the possibilities and limitations of using the 1H NMR metabolomics platform to study food and food systems (foodomics). The merger of food science with advanced analytical tools, such as high-resolution NMR and multivariate data analysis chemometrics, has proven to be tremendously successful. The “weak whispers” from the protons in our food have been proven to contain a plethora of information about our aliments and to be useful in multiple applications within advanced quality control, which is not possible with existing optical spectroscopies, in particular for addressing the multiple and systemic issues related to safety and quality of food.

Primary and secondary sludge treatment using ionizing radiation technology in Alexandria, Egypt

In order to apply black iron oxide nanoparticles in a medical application for humans, despite the requirement quality based on the physical, chemical, and biological perspectives, controlling a fabrication process is also essential to guarantee the halal product according to the Islamic view. In this paper, we report the controlling process parameters in the fabrication of black iron oxide nanoparticles. Based on the data analysis, black iron oxide nanoparticles fabricated in this work were suitable as a halal product. Natural iron sand as the primary precursor taken from natural resources was firstly washed with water several times so that the iron sand was completely free of impurities, especially from animal waste. In the Islamic perspective, animal waste is an unclean object that can block the halal condition of a product. Dissolving and precipitating processes were also carefully controlled to obtain a halal product free of unclean surfactant. Finally, to guarantee that the product formed in nanometric size, we investigated the product using X-ray diffraction, presenting that the fabricated black iron oxide nanoparticles were constructed in a single phase with the average particle size of < 100 nm. According to Indonesian regulation, it is also essential to obtain halal certification from the Indonesian Ulema Council.

The spontaneous association of oppositely charged natural or synthetic polyelectrolytes in solution has evoked a great deal of interest from chemical, physical, and biological perspectives. The polymer-dense phases resulting from this phase separation are termed polyelectrolyte complexes or coacervates, PECs. PECs exhibit a range of properties and morphologies, from liquidlike to solidlike states. Though PECs have high water contents, a few of them are known to exhibit a glass transition near room temperature. In this work, the library of glassy PECs is substantially expanded with compositions that exhibit glass transition temperatures, Tg, over the entire working range of aqueous solutions between 0 and 100 °C. A radiochemical method of measuring the volume of pores that usually form in glassy PECs enabled a comparison of Tg with PEC phase water volume fraction, ϕH₂O,PEC. Tg correlated weakly with ϕH₂O,PEC only for a series of PECs in which one of the polyelectrolytes was held constant. In general, Tg was poorly correlated with ϕH₂O,PEC. On the other hand, time–temperature superposition of linear viscoelastic responses provided a classical estimate of fractional free volume of PECs, which correlated well with Tg.

Influence of mediterranean cereal-based rotations on soil micromorphological characteristics

Since the mid-20th century, the quantity of microplastics (MPs) has increased significantly, becoming a persistent environmental pollutant widely distributed in global water bodies, soils, and the atmosphere. While plastic materials have brought significant convenience to daily life, the MPs resulting from their degradation pose increasing threats to ecosystems and human health. This comprehensive review examines the sources, migration pathways, and ecological impacts of MPs, and critically evaluates the current separation techniques from physical, chemical, and biological perspectives. In particular, numerical simulations of the hydrocyclone separation technique reveal its unique flow characteristics, including turbulent velocity gradients and axial pressure differences, with a separation efficiency of up to 93%. This technique offers advantages such as high efficiency, low energy consumption, and environmental friendliness. In response to the growing microplastic pollution issue, this review emphasizes that the development of future microplastic separation techniques should prioritize separation efficiency, sustainability, and environmental compatibility. Continued research in this field will provide theoretical support for optimizing microplastic pollution control technologies and contribute to achieving environmental protection and sustainable development goals.

High-sensitivity detection of minute quantities or concentration variations of analytes of clinical importance is critical for biosensing to ensure accurate disease diagnostics and reliable health monitoring. A variety of sensitivity-improving concepts have been proposed from chemical, physical, and biological perspectives. In this review, elements that are responsible for sensitivity enhancement are classified and discussed in accordance with their operating steps in a typical biosensing workflow that runs through sampling, analyte recognition, and signal transduction. With a focus on optical biosensing, exemplary sensitivity-improving strategies are introduced, which can be developed into "plug-and-play" modules for many current and future sensors, and discuss their mechanisms to enhance biosensing performance. Three major strategies are covered: i) amplification of signal transduction by polymerization and nanocatalysts, ii) diffusion-limit-breaking systems for enhancing sensor-analyte contact and subsequent analyte recognition by fluid-mixing and analyte-concentrating, and iii) combined approaches that utilize renal concentration at the sampling and recognition steps and chemical signal amplification at the signal transduction step.

In a recent experimental work, results of the first transition voltage spectroscopy (TVS) investigation on azurin have been reported. This forms a great case to better understand the electron transfer through bacterial redox metalloproteins, a process of fundamental importance from chemical, physical, and biological perspectives, and of practical importance for nano(bio)electronics. In the present paper we challenge the tentative interpretation put forward in the aforementioned experimental study and propose a different theoretical interpretation. To explain the experimental TVS data, we adopt an extended Newns–Anderson framework, whose accuracy and robustness is demonstrated. We show that that this framework clearly meets the need to obtain a consistent description across experiments. Most importantly, the presently proposed theoretical approach permits unraveling novel aspects on the impact of the electrochemical scanning microscope environment on the charge transport through single-(bio)molecule junctions based on redox units. The usefulness of TVS as a versatile method of investigation, also able to provide important insight into the charge transport through metalloproteins, is emphasized.
