Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

open access: yesAdvanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

Daily Emissions of CO2 in the World: A Fractional Integration Approach

open access: yesEconometrics
In this article, daily CO2 emissions for the years 2019–2022 are examined using fractional integration for Brazil, China, EU-27 (and the UK), India, and the USA.

Mean reversion of inflation rates in 19 OECD countries: Evidence from panel Lm unit root tests with structural breaks [PDF]

open access: yes
The paper applies the recently developed panel LM unit root tests with heterogeneous structural breaks by Im et al., [The Oxford Bulletin of Economics and Statistics, 2005] in order to re-examine the validity of mean reversion in the inflation rates of ...

Solvent‐Free Thermal Defect Engineering in Molecular Frameworks With Volatile Linkers

open access: yesAdvanced Materials, EarlyView.
Thermal removal of neutral volatile linkers enables precise and solvent‐free generation of metal vacancies in MOFs. This strategy affords redox‐stable, coordinatively unsaturated FeII sites with tunable spin, ligand coordination, and catalytic behavior. The approach offers a general route to design defect‐functional materials through local coordination

Nonlinear Mean Reversion across National Stock Markets: Evidence from Emerging Asian Markets [PDF]

open access: yes
This paper seeks empirical evidence of nonlinear mean-reversion in relative national stock price indices for Emerging Asian countries. It is well known that conventional linear unit root tests suffer from low power against the stationary nonlinear ...

Silver Ions as Ambipolar Dopants in InAs Nanocrystal Solids

open access: yesAdvanced Materials, EarlyView.
Ag⁺ ions post‐introduced into InAs nanocrystal films act as ambipolar dopants whose effect depends on host polarity and dopant concentration. In n‐type InAs nanocrystal films, Ag⁺ occupies interstitial sites to yield n‐type doping effect, whereas in Zn‐doped p‐type InAs nanocrystal films, it first forms p‐type surface doping effect and later induces n ...

Autonomous Spatiotemporal Regulation of Reversible Hydrogel Actuators by Chemical Reaction Networks

open access: yesAdvanced Materials, EarlyView.
Hydrogel actuators with reversible response to thiols are developed using reversible binding of thiols to Michael acceptors. Autonomous spatiotemporal regulation of reversible movement of these hydrogels is achieved using thiol‐based chemical reaction networks containing both positive and negative feedback.
