PROMOTION STRATEGY OF SCIENTIFIC VOCATION IN SECONDARY EDUCATION BY MEANS OF NANOSCIENCE AND NANOTECHNOLOGY DIFFUSION IN COSTA RICA

Momento, 2013
Current strategies in education leave nanoscience and nanotechnology aside from the process of learning the scientific method, thereby omitting a large portion of contemporary empirical knowledge. It is thus desirable to familiarize students in secondary

Effect of Zinc Oxide Nanoparticles From Infant Formula Milk Powder on Colon Cells In Vitro

Journal of Applied Toxicology, EarlyView.
ABSTRACT Zinc is an essential trace element that participates in numerous metabolic processes; however, excessive exposure may interfere with the absorption of other metals, such as copper. In recent years, nanotechnology has experienced rapid growth, and zinc oxide nanoparticles (ZnO NPs) have garnered significant attention due to their versatile ...

4D Printable Formulations of Mixed Low and High Molecular Weight Liquid Crystalline Units: A Versatile Route to Functional Soft Actuators

Macromolecular Rapid Communications, EarlyView.
This work presents a practical approach for formulating 4D printable inks that incorporates substantial fractions of low molecular weight mesogens. By blending low molecular weight diacrylate or monoacrylate constituents with a high molecular weight main‐chain macromer, the resulting mixture proves suitable for direct ink writing, enabling mechanical ...

Chemically‐Linked Heterostructures of Palladium Nanosheets and 2H‐MoS2

Small, EarlyView.
The photoresponse of MoS2 devices is extended to the near‐infrared region (up to 1700 nm) through chemical connection to Pd nanosheets (PdNS). A maleimide is used for covalent connection to MoS2, and a phenyl bromide moiety for linkage to the PdNS. In the absence of the chemical linker, van der Waals heterostructures show poorer enhancement of the ...

Liquid‐Processed 2D Aromatic Amorphous Carbon: Defect Engineering and Universal Transport Scaling

Small, EarlyView.
Liquid‐processed graphene oxide (GO) thin films undergo a controllable crystalline–to–amorphous transition driven by thermal quenching. By kinetically tuning oxygen‐driven defect formation during reduction, scalable 2D aromatic amorphous carbon phases are stabilized, directly linking nanoscale disorder and defect topology to electronic transport ...

Covalent Functionalization of NiFe Layered Double Hydroxides using Tris(Hydroxymethyl)Aminomethane

Small, EarlyView.
Covalent functionalization of NiFe layered double hydroxides with tris(hydroxymethyl)aminomethane enables controlled growth, enhanced structural order, and improved processability. Temporary TRIS anchoring promotes stable water‐based inks and binder‐free electrode fabrication, leading to enhanced oxygen evolution activity and long‐term stability under ...
