“…The hydroxyl radicals are the most potent destructing free radicals in biological systems and can degenerate every biological molecule [ 14 ]. Under oxidative attack, the plant promotes its radical scavenging system against inorganic contaminants with the help of antioxidants enzymes such as superoxide dismutase (SOD), catalase (CAT), and ascorbate peroxidase (APX) to rejuvenate the developing parts of plants [ 15 , 16 , 17 ].…”

Zinc Application Mitigates Copper Toxicity by Regulating Cu Uptake, Activity of Antioxidant Enzymes, and Improving Physiological Characteristics in Summer Squash

et al. 2022

Zinc (Zn) and copper (Cu) are essential micronutrients for the plant’s growth, development, and metabolism, but in high concentrations, the elements disrupt normal metabolic processes. The present study investigated the effects of different concentrations (added to a Hogland-based solution) of zinc (control, 5, 10 mg L−1 ZnSO4) and copper (control, 0.1, 0.2 mg L−1 CuSO4) on the growth characteristics and biochemical indices of summer squash (Cucurbita pepo L.). Compared with control, a single application of Cu or Zn at both concentrations significantly declined fruit yield, growth traits, pigments content, and high content of these minerals and values of stress-related indices. Increased Cu concentration in the nutritional solutions reduced the activity of ascorbate peroxidase (APX) and guaiacol peroxidase (GPX). Copper at high concentrations intensified ROS production, aggravated oxidative stresses, and decreased the plant yield and productivity. Nonetheless, combining Cu and Zn could alleviate stress intensity by boosting antioxidant enzymes, redox regulation, and a resultant diminishment in the content of H2O2, proline, malondialdehyde, and minerals. The obtained results corroborate that the co-application of zinc in Cu-contaminated areas can improve the plant’s economic yield and physiological parameters by hindering copper toxicity and enhancing the photosynthetic capacity.

“…In addition to fixing nutrients, microbes also break down organic matters or plant litter in soils, in turn affecting the soil fertility (Albornoz et al 2022;He et al 2022;Liu et al 2022;Sokol et al 2022;Tian et al 2022a, b;Tonello et al 2022;Turan et al 2019;Wang et al 2022a, b). Meanwhile, the metal cation released by microorganisms within BSCs also could fix nutrients form water and dust into soils (Hafsteinsdóttir et al 2015;Netherway et al 2019;Rasool et al 2022;Tauqeer et al 2022). Therefore, BSCs are usually regarded as promising and economic tools for ecological restoration engineering, particularly for degraded ecosystems in alpine regions, which are fragile ecosystems (Bu et al 2015a, b;Deng et al 2020;Lu et al 2022a).…”

Background The rock cut slope (RCS) could cause damage to regional ecological functions and landscapes and requires recovery. Biological soil crusts (BSCs) are pioneer and dominant colonizers during the initial recovery stage. To accelerate the natural recovery of RCS, the development process and influencing agents of BSC should be revealed. Thus, the area index of crevices (IR), BSC coverage (COV) and biomass (BM), soil weight (SW), and major soil nutrients [organic carbon (OC), total nitrogen (TN) and total phosphorus (TP)] content, collected from 164 quadrats on 13 RCSs in the mountainous area of west Sichuan Province, China, were measured, to explore the effect of crevice of RCS on BSC development. Results Soil OC, TN and TP on RCSs ranged from 18.61 to 123.03 g kg−1, 0.96 to 6.02 g kg−1 and 0.52 to 2.46 g kg−1, respectively, and were approximately to or higher than those on natural slopes. The OC, TN and TP contents in soils elevated unsystematically with recovery time of RCSs. BSCs on RCS distributed along crevices generally and firstly. During the first 13 years of natural recovery, COV, BM and SW ranged from 6.5 to 28.2%, 14.43 to 67.25 g m−2, and 127.69 to 1277.74 g m−2, respectively. COV, BM and SW increased linearly with IR on RCSs. The positive correlation between COV and BM and IR was insignificantly impacted by bedrock, slope aspect and altitude within the recovery time less than 13 years. COV and BM on RCSs increased significantly when the recovery time is more than 27 years. Conclusions Crevice on RCSs could be a major environmental factor which is conducive to BSC development and soil accumulation through creating a space for water and soil particle. Furthermore, with the increase of recovery time of RCSs, BSCs may grow and reach a stable state with the promotion of soil nutrients, plant growth and microbial activity. These results provide a development process of BSC that from inside to outside the crevices on RCSs. In the areas with stable rock strata and a low risk of geological disasters, purposeful improvement in crevice density on RCS may effectively accelerate BSC development.

“…Chitosan (CS) is a semicrystalline polysaccharide derived from chitin, the second most important natural polymer that can be extracted from the shells of crustaceans. Due to its physical and chemical properties, it has been an attractive alternative for several technological applications, including biomedical, pharmaceutical, and environmental applications. − CS has also been used extensively as a membrane matrix owing to its excellent film forming with good mechanical properties. , The structure comprises repeating units of N-acetyl d -glucosamine and d -glucosamine, shown in Figure S1 in the Supporting Information.…”

Enhanced Chitosan Photoluminescence by Incorporation of Lithium Perchlorate

et al. 2023

View full text Add to dashboard Cite

An improvement in chitosan film photoluminescence was observed after adding LiClO 4 . FTIR spectra, XPS, DFT calculations, and XRD measurements show an alteration of the Hbonds and an increase in the amorphous character of chitosan. PL spectra display a growth in intensity in the visible region along with the incorporation of lithium, signaling a possible rise in the population density of tail states and, consequently, better photon absorption, as observed from UV−vis measurements. A mechanism through aggregation-induced emission effect is proposed to explain the different results. Although this work establishes the relation between structural changes provoked by LiClO 4 incorporation and luminescence in the case of chitosan, we expect that the same approach could be generalized to similar polymeric structures.
