Converting Durian Husk Into Adsorbent Beads for Methylene Blue Adsorption: Synthesis, Kinetics, Isotherms, and Reusability

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Environmental pollution from textile dyeing wastewater, particularly the discharge of harmful dyes like methylene blue (MB), poses a significant challenge. This study presents an innovative solution for dyeing wastewater treatment by utilizing durian husk, an agricultural waste, as an adsorbent for MB removal.

Long‐term prognosis is associated with residual disease after neoadjuvant systemic therapy but not with initial nodal status

open access: yesBJS (British Journal of Surgery), EarlyView., 2020
This long‐term follow‐up study determined survival rates in a Swedish national cohort of 417 patients with breast cancer who all had neoadjuvant systemic therapy (NAST). Sentinel lymph node biopsy (SLNB) was performed before NAST in clinically node‐negative and after NAST in clinically node‐positive patients.

Sustainable Graphene Oxide–Intercalated Bentonite Composite for the Effective Removal of Imidacloprid From Water: Adsorption Performance, Isotherm, and Kinetics

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Water is a fundamental necessity for our existence, but its rapid contamination is causing devastating effects on the environment and health of living species worldwide. Adsorptive removal of pollutants is one of the popular water treatment techniques because of its simplicity, affordability, and the broad range of available adsorbents.

A Kinetic Framework for the Pyrolysis of Poly(Ether‐Ketone‐Ketone) (PEKK)

open access: yesJournal of Applied Polymer Science, EarlyView.
Crosslinking influences poly(ether‐ether‐ketone) (PEKK) pyrolysis. ABSTRACT Research to date on the thermal degradation of poly(ether‐ketone‐ketone) (PEKK) has largely been limited to low temperatures or analysis as part of a composite. Herein, we investigate the pyrolysis kinetics of neat PEKK from 480°C to 1000°C and characterize the degradation by ...
