Preparation and characterization of chitosan for heavy metal ions removal

, 2013
Kitosan ve epiklorohidrin ile çapraz bağlanmış kitosanpartikülleri sulu ortamdan ağır metallerin tersinir biçimde adsorpsiyonu ve uzaklaştırılması için hazırlandı. Bu çalışma üç ana bölüm olarak organize edildi. Çalışmanın ilk kısmında, kitosan partikülleri 3.0 g kitosanın %2 asetik asit içeren 100 mL çözeltide çözünmesi ve ardından 2 M sodyum ...

The cell wall functions in plant heavy metal response

Ecotoxicology and Environmental Safety
Nonessential metals (e.g., cadmium (II), etc) and essential heavy metals (e.g., copper (II), etc) are both toxic for plants at high concentrations. The plant cell wall, which consists of pectin, cellulose, hemicellulose, lignin and proteins, acts as the ...

Understanding the Role of Superhydrophobicity and Superhydrophilicity in Salt‐Spray Corrosion of Nanosecond Pulsed Laser‐Textured AA2024 Alloy

Advanced Functional Materials, EarlyView.
Nanosecond pulse laser texturing yields superhydrophobic and superhydrophilic AA2024 surfaces. Salt‐spray tests show that periodic superhydrophobic patterns suppress pitting, whereas superhydrophilic textures enhance it, linking laser‐induced morphology, wettability, and oxide chemistry to corrosion resistance.

Complexation‐Mediated Diffusion‐Limited Crystal Growth: A General Framework for Anisotropic Crystal Growth in Cu‐Based Perovskites

Advanced Functional Materials, EarlyView.
A Complexation‐Mediated Diffusion‐Limited Growth (CMDLG) framework is established to rationalize the anisotropic growth of lead‐free perovskites. Integrating coordination chemistry with mass transport kinetics, this study theoretically derives and experimentally validates that stable iodocuprate complexes induce a diffusion‐limited regime.

Light Activated Induction of Cuproptosis in Resistant Cancer Cells Using Polymeric BODIPY Nanoparticles for Photoactivated Chemotherapy

Advanced Functional Materials, EarlyView.
This article presents a photo‐responsive nanoparticle platform that precisely triggers copper‐dependent cuproptotic cell death in (drug‐resistant) cancer cells. The system remains stable and inactive in the dark but releases cytotoxic species upon red‐light irradiation, achieving potent activity in drug‐resistant breast cancer cells.

The influence of heavy metals on the production of extracellular polymer substances in the processes of heavy metal ions elimination

Water Science and Technology, 2005
Wastewaters from a chemical industry polluted by heavy metal ions represent a hazard for all living organisms. It can mean danger for ecosystems and human health. New methods are sought alternative to traditional chemical and physical processes. Active elimination process of heavy metals ions provided by living cells, their components and extracellular
