The escalating challenges in water treatment, exacerbated by climate change, have catalyzed the emergence of innovative solutions. Novel adsorption separation and membrane filtration methodologies, achieved through molecular structure manipulation, are gaining traction in the environmental and energy sectors. Separation technologies, integral to both the chemical industry and everyday life, encompass concentration and purification processes. Macrocycles, recognized as porous materials, have been prevalent in water treatment due to their inherent benefits: stability, adaptability, and facile modification. These structures typically exhibit high selectivity and reversibility for specific ions or molecules, enhancing their efficacy in water purification processes. The progression of purification methods utilizing macrocyclic frameworks holds promise for improved adsorption separations, membrane filtrations, resource utilization, and broader water treatment applications. This review encapsulates the latest breakthroughs in macrocyclic host-guest chemistry, with a focus on adsorptive and membrane separations. The aim is to spotlight strategies for optimizing macrocycle designs and their subsequent implementation in environmental and energy endeavors, including desalination, elemental extraction, seawater energy harnessing, and sustainable extraction. Hopefully, this review can guide the design and functionality of macrocycles, offering a significantly promising pathway for pollutant removal and resource utilization.

Exogenous melatonin and grafting improved the growth and physiological characteristics of Citrullus lanatus seedlings under cadmium stress.
Environ Sci Pollut Res Int

College of Horticulture and Landscape Architecture, Tianjin Agricultural University, Tianjin, 300392, China.
Citrullus lanatus is an important vegetable crop, but it is heavily polluted by cadmium. In this study, we used C. Lanatus as experimental material to investigate effects of different concentrations (0, 50, 100, 200, 400 µmolL) of exogenous melatonin, and grafting on the physiological growth index and anatomical structure of seedlings were studied by simulating Cd (180 mg L) stress environment.

The Lentinus edodes polysaccharide (LEP) was extracted with a new subcritical water extraction (SWE) enhanced with deep eutectic solvent (DES) method and then purified with a DEAE-52 cellulose column and a Sephadex G-100 column. Two purified polysaccharides (LEP1 and LEP2) were obtained and their structure, antioxidant activity, and immunomodulatory activity were analyzed. LEP1 and LEP2 were composed of mannose, glucose, and galactose with a molar ratio of 1:12.

Premise: The ability of plants to adapt or acclimate to climate change is inherently linked to their interactions with symbiotic microbes, notably fungi. However, it is unclear whether fungal symbionts from different climates have different impacts on the outcome of plant-fungal interactions, especially under environmental stress.
Methods: We tested three provenances of fungal inoculum (originating from dry, moderate or wet environments) with one host plant genotype exposed to three soil moisture regimes (low, moderate and high).
Arteriolar Elasticity Measurement in the Fingertip Based on Photoplethysmographic Volume-Oscillometry: A New Approach to the Assessment of Vasomotor Functions in the Microvasculature.

Purpose: Dysfunction of vasomotor reactions due to arteriolar smooth muscle causes serious adverse events, such as loss of hemodynamic coherence. This in turn can increase risks of cardiovascular-related diseases. A noninvasive and quantitative evaluation of microvascular disorder is therefore very important for early diagnosis and treatment.

Aeolian sandy soil is barren and readily leads to low fertilizer utilization rates and yields. Therefore, it is imperative to improve the water and fertilizer retention capacity of these soils. In this paper, three kinds of biochar (rice husk, corn stalk, and bamboo charcoal) and bentonite were used as amendments in the first year of the experiment.
