Multi‐Module Micro/Nanorobots for Biomedical and Environmental Remediation Applications
Multi‐module microrobots (MNRs) have overcome the limitations of single‐module systems by integrating components such as propeller, actuator, manipulator, and imaging modalities. They show promise in biomedical applications, such as targeted drug delivery and tissue repair, as well as in environmental remediation, including pollutant removal.

Oxidation of magnetite nanoparticles: impact on surface and crystal properties
Iron oxide nanoparticles are of great scientific interest due to their huge versatility of applications. The oxidation process of magnetite to maghemite is difficult to monitor as both iron oxide polymorphs possess connatural chemical properties ...

ABSTRACT At the Huacas de Moche (HdM), one of the most prominent archaeological sites in Trujillo, Peru, the needs of an expanding modern community are in direct conflict with the desire to preserve the wealth of archaeological information. The undetermined extent of the HdM site introduces disputes in land usage where potential archaeological features

Enhancement of Pb and Cd Adsorption in Water Samples by Magnetite Using Humic Acid as Modifier
BACKGROUND Magnetite is widely used as a green and cheap mineral material to adsorb heavy metals in water samples, but it has the disadvantages of low adsorption capacity, poor selectivity and easy reunion.

Additively Manufactured Binder‐Free Electrodes for Supercapacitors
The study presents an innovative manufacturing process for electrodes in supercapacitors. The masked stereolithography method is used to produce electrodes that do not require a binder or metal foil. The printed electrodes have a microporous charter. Electrochemical measurements show that the additively manufactured electrodes behave in the same way as
