With the increasing use of metal–organic frameworks (MOFs), they will inevitably enter environment intentionally or unintentionally. However, effects MOFs on plant growth are poorly understood. Here, we investigated exposure rhizosphere to growth. MIL-101(Cr) was selected as a research model due its commercial availability and wide use. Soybean plants at two-leaf stage were subjected various durations (1–7 days) concentrations (0–1000 mg/L) in hydroculture with control group treated ultrapure water. We found that had positive effect soybean lower dose (i.e., 200 mg/L); however, higher doses 500 1000 mg/L), it exhibited significant toxicity growth, which is evidenced by leaf damage. To investigate mechanism this effect, used Cr an indicator quantify, track, image laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS). Results indicated primarily accumulated cortex roots (up 40 times than stems), limited translocation stems negligible presence leaves cotyledons. In addition, metabolomic analysis soybeans low-dose could increase sucrose content promote while high induce lipid oxidation roots. This study provides valuable insights into ecological toxicology underscores importance assessing their environmental impact for sustainable agricultural practices.

Nanospace Engineering for C₈ Aromatic Isomer Separation

ACS Nano, Год журнала: 2025, Номер unknown

Опубликована: Янв. 6, 2025

C8 aromatic isomers, namely para-xylene (PX), meta-xylene (MX), ortho-xylene (OX), and ethylbenzene (EB), are essential industrial chemicals with a wide range of applications. The effective separation these isomers is crucial across various sectors, including petrochemicals, pharmaceuticals, polymer manufacturing. Traditional methods, such as distillation solvent extraction, energy-intensive. In contrast, selective adsorption has emerged an efficient technique for separating in which nanospace engineering offers promising strategies to address existing challenges by precisely tailoring the structures properties porous materials at nanoscale. This review explores application modifying pore characteristics diverse materials─including zeolites, metal-organic frameworks (MOFs), covalent organic (COFs), other substances─to enhance their performance isomer separation. Additionally, this provides comprehensive summary how different techniques, temperature fluctuations, enthalpy/entropy considerations, desorption processes influence efficiency. It also presents forward-looking perspective on remaining potential opportunities advancing

A Series of Rare-Earth Metal-Based Coordination Polymers: Fluorescence and Sensing Studies

Sensors, Год журнала: 2024, Номер 24(21), С. 6867 - 6867

Опубликована: Окт. 25, 2024

Ratiometric fluorescent sensing based on dual-emitting coordination polymers (FL-CPs) has attracted intense attention due to their accuracy and easy visualization when compared with relying solely monochromatic FL-CPs. In this work, a series of rare-earth metal-based CPs, formuled as [(CH
