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 ...

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.

Investigation on the efficiency of food waste fermentation solution as a supplementary carbon source for electroplating wastewater treatment

Gongye shui chuli
Large volumes of carbon sources must be added to electroplating wastewater to remove nitrogen and sustain microbial development as the wastewater contains high concentrations of nitrate nitrogen and a range of mixed heavy metal ions.

Resonant charging and stopping power of slow channelling atoms in a crystalline metal

, 2012
Fast moving ions travel great distances along channels between low-index crystallographic planes, slowing through collisions with electrons, until finally they hit a host atom initiating a cascade of atomic displacements.

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.

Comparative study of heavy metal-induced oxidative stress responses in Schizophyllum commune Fr. and Cyathus striatus Willd.

Acta Biologica Slovenica
Heavy metal exposure causes reactive oxygen species generation and oxidative stress in nearly all aerobic organisms. Antioxidant enzymes with free radical scavenging properties counter this oxidative stress produced by heavy metals.

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.

Photon Avalanching Nanoparticles: The Next Generation of Upconverting Nanomaterials?

Advanced Functional Materials, EarlyView.
This Perspective outlines the mechanistic foundations that enable photon‐avalanche (PA) behavior in lanthanide nanomaterials and contrasts them with emerging application spaces and forward‐looking design strategies. By bridging threshold engineering, energy‐transfer dynamics, and materials engineering, we provide a coherent roadmap for advancing the ...
