Fenton‐like Reactivity on Fe3O4 Nanozymes Driven by Charge Transfer and Interfacial Water

open access: yesSmall, EarlyView.
In magnetite nanozymes, subsurface Fe2⁺ donates electrons to H2O2, forming fleeting Fe(IV)═O and •OH species. The process couples charge flow, water‐mediated reactivity, and nanoparticle oxidation in a dynamic Fenton‐like cycle. Abstract Magnetite (Fe3O4) nanoparticles, widely recognized as inorganic nanozymes due to their enzyme‐like catalytic ...

Surface Engineering of Ti3C2Tx MXenes via Silanol Functionalization for Improved Electrochemical Performance

open access: yesSmall, EarlyView.
This study explores the covalent functionalization of Ti3C2Tx using 5,5′‐bis(triisopropoxysilyl)‐2,2′‐bipyridine in different solvents, revealing that only m‐xylene enables effective covalent bonding, ensuring structural stability and preventing layer swelling.

Extensile Active Hydrogels Driven by Living FtsZ Polymers

open access: yesSmall, EarlyView.
Upon post‐gelation activation with Mg2⁺/GTP, living FtsZ polymers treadmill inside a polyacrylamide network, generating extensile internal stresses that drive isotropic swelling and softening. Interpreting mechanics against a Flory–Rehner swelling baseline separates passive dilution from genuine activity, revealing an FR‐normalized permittivity that ...

Optimizing the construction process: State‐of‐art, innovations, and potential benefits of temperature match curing

open access: yesStructural Concrete, EarlyView.
Abstract The temperature match curing (TMC) method significantly enhances the accuracy of concrete property assessments by replicating in situ curing conditions in test specimens. While this method has remained underutilized and relatively unknown in the industry due to its complexity, the advent of Internet of Things and wireless sensor technologies ...

Preliminary Appraisal of a Correlation Between Glaciations and Large Igneous Provinces Over the Past 720 Million Years

open access: yesGeophysical Monograph Series, Page 169-190., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Optimisation of the biological production of levulinic acid in a mixed microbial culture fed with synthetic grape pomace

open access: yesFrontiers in Bioengineering and Biotechnology
Levulinic acid (LA) is a polymer with a vast industrial application range and can be co-produced as a minor by-product during the biological production of polyhydroxyalkanoates (PHA).

Candida antarctica lipase-catalyzed synthesis and characterization of novel acrylic teroligomers [PDF]

open access: yes, 2018
The synthesis of three novel low molecular weight acrylic terpolymers, containing at random sequences of ethyl acrylate, acrylic acid and N-(2-hydroxyethyl)acrylamide, catalyzed by Candida antarctica lipase was successfully conducted in organic media ...
