Bacterial Oxidation and Reduction of Iron in the Processes of Creation and Treatment of Acid Mining Waters [PDF]

open access: yesActa Montanistica Slovaca, 2004
Acid mine drainages (AMDs) arise at the weathering of sulphidic minerals. The occurrence of acidic streams is commonly associated with the human mining activities.

Processability and Crosslink Density: Role of Peptizers in Natural Rubber and Chlorobutyl Rubber

open access: yesJournal of Applied Polymer Science, EarlyView.
This work evaluates how chemical and physical peptizers affect mastication, vulcanization behavior, and network formation in natural rubber and chlorobutyl rubber. Size‐exclusion chromatography, rheometry, DSC, and swelling analyses demonstrate improved processability but reduced crosslink density with peptizer addition.

Advancing design strategies in smart stimulus‐responsive liposomes for drug release and nanomedicine

open access: yesBMEMat, EarlyView.
Schematic illustration of stimulus‐responsive liposomes designed for controlled drug release and nanomedicine. The innermost circle represents different liposomal structures, including unilamellar, multilamellar, and multivesicular liposomes. The middle layer illustrates the responsive phospholipid components.

A normalised seawater strontium isotope curve: possible implications for Neoproterozoic-Cambrian weathering rates and the further oxygenation of the Earth [PDF]

open access: yes, 2007
The strontium isotope composition of seawater is strongly influenced on geological time scales by changes in the rates of continental weathering relative to ocean crust alteration.

Multifunctional Design of Solid Polymer Electrolytes: Paving the Way for High‐Performance All‐Solid‐State Batteries

open access: yesCarbon Energy, EarlyView.
This review provides a comprehensive and systematic overview of the multifunctional design strategies for solid polymer electrolytes (SPEs), a pivotal component for enabling high‐performance all‐solid‐state batteries (ASSBs). It begins with a detailed classification of SPE systems and elaborates on their respective molecular design principles. The work

From Food Waste to Valorized Nanomaterials: Sustainable Green Synthesis and Biomedical Applications

open access: yesChemFoodChem, EarlyView.
Food waste‐derived biomolecules act as natural reducing and stabilizing agents for the green synthesis of functional NPs with applications in antimicrobial systems, food packaging, biomedical technologies, and environmental remediation. ABSTRACT Food waste is a global issue, with billions of tons discarded and unutilized annually, causing economic ...

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

open access: yesChemistry – A European Journal, EarlyView.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.

Gels as battery separators for soluble electrode cells [PDF]

open access: yes, 1977
Gels are formed from silica powders and hydrochloric acid. The gels are then impregnated into a polymeric foam and the resultant sheet material is then used in applications where the transport of chloride ions is desired.
