Mechanical cleaning of graphene

open access: yes, 2011
Contamination of graphene due to residues from nanofabrication often introduces background doping and reduces charge carrier mobility. For samples of high electronic quality, post-lithography cleaning treatments are therefore needed.

Covalent Immobilization of Laccase on Mesoporous Bismuth Silicate for High‐Performance Biodegradation of Contaminants

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Myceliophthora thermophila laccase covalently immobilized on bismuth silicate (BiSi‐ext) achieved synergistic adsorption–biodegradation of Tectilon Blue 4R‐01 and ibuprofen. The biocatalyst showed enhanced stability, reusability, and rapid pollutant removal via expanded active‐site accessibility, enabling efficient, eco‐friendly wastewater remediation.

Geochemical and Geological Investigation of Skarn‐Type Pb–Zn Mineralization in Hastanetepe (Balya‐Balıkesir, Türkiye): An Approach Based on Fluid Inclusions, Sulphur Isotopes and Geochemical Data

open access: yesGeological Journal, EarlyView.
Integrated petrographic, mineralogical and geochemical data from the Hastanetepe Pb–Zn deposit (Balya, Türkiye) reveal multi‐stage hydrothermal alteration and a magmatic sulphur source. Fluid inclusion and sulphur isotope results indicate a complex fluid evolution responsible for skarn‐type Pb–Zn mineralization along limestone–dacite contacts ...

Between Consistency and Adaptation: How Middle Managers Shape Compensation System Implementation

open access: yesHuman Resource Management, EarlyView.
ABSTRACT The success of a human resource management (HRM) system or subsystem, such as a compensation system, hinges on its implementation—yet the microfoundations of this process remain underexplored. To address this gap, we conducted two studies. Study 1 surveyed middle managers and employees in six organizations to examine their attributions of ...
