Surface Modification of Celluloses Extracted from Oil Palm Empty Fruit Bunches for Heavy Metal Sorption

Chemical Engineering Transactions, 2014
Contamination of environment with heavy metals such as cadmium, cobalt, copper, nickel and manganese is becoming a major problem due to their toxicity persistency and bioaccumulation tendency. Cellulose fibers extracted from Oil Palm Empty Fruit Bunches (

Redirecting Nano‐Silicon Agglomeration: Dual‐Carbon Design Triggers Self‐Adaptive Nanoporous Si Sponge for Enhanced Lithium Storage

Advanced Functional Materials, EarlyView.
This study addresses silicon anode degradation using an engineered nSi/Gr/C dual‐carbon matrix. By restricting SEI infiltration, the architecture redirects silicon agglomeration into a beneficial structural self‐adaptive activation. During cycling, silicon nanoparticles self‐organize into a resilient nanoporous sponge. This dynamic network accommodates

Evaluation of an Adsorption–Desorption Process for Concentrating Heavy Metal Ions from Acidic Wastewaters

Adsorption Science & Technology, 2009
Pine bark is a substrate which allows the attachment and de-activation of heavy metal ions, thereby cleansing the host solution. The present work was aimed at studying the removal of binary heavy metal ions from aqueous solutions using pine bark and to ...

Photothermal‐Activated Antibacterial Amyloid‐Polyphenol‐Iron Hydrogels for Synergistic Wound Healing

Advanced Healthcare Materials, EarlyView.
We report a thermally triggered supramolecular hydrogel (LTFe) formed by Fe3+ and tannic acid on lysozyme amyloid fibrils. Fe3+ enables rapid gelation and photothermal transduction with an efficiency of 88.56%. The LTFe hydrogel exhibits excellent biocompatibility, potent antibacterial activity against E. coli and S.

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.

Immunoinflammatory Mechanisms and Biocompatibility of Bioactive Dental Biomaterials: From Fundamental Insights to Clinical Translation

Advanced Healthcare Materials, EarlyView.
Surface‐host dialogue at the implant interface governs biological fate and osseointegration. Surface physicochemical properties of titanium (Ti) dental implants, including microgrooves, nanopatterns, nanotopography, roughness, and wettability, modulate the initial adsorption of proteins and the formation of a dynamic biointerface.

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.

Affinity‐Tuned Albumin Hitchhiking Extends the Bioorthogonal Capture Window in Pretargeting Radiotheranostics

Advanced Healthcare Materials, EarlyView.
Pharmacokinetic engineering of clickable radioligands was achieved via albumin hitchhiking approach within a pretargeted radiotheranostics delivery platform. This approach reduced rapid renal elimination, expanded bioorthogonal capture window, boosted tumor uptake by ∼3.5‐fold, and improved the tumor‐to‐liver ratio by ∼6‐fold.
