Lithographically Controlled Liquid Metal Diffusion in Graphene: Fabrication and Magnetotransport Signatures of Superconductivity. [PDF]

Adv Mater
Lithography‐guided intercalation creates a proximitized 2D superconducting Ga layer under graphene Hall bars via liquid‐metal intercalation. The image shows a Hall bar where Ga atoms from the liquid phase enter through patterned intercalation channels beneath quasi‐freestanding bilayer graphene, forming a confined 2D metal that demonstrates ...

Vortex Ratchet Effect in a NbC Strip With a Periodic Edge Indentation. [PDF]

Small Methods
The image shows the nanoprinting of a superconducting nanostructure using focused ion beam induced deposition (top left), overlaid with numerically simulated patterns of current and magnetic flux quanta (bottom). An edge indentation breaks spatial symmetry, modifying the current density distribution and inducing nonreciprocal magnetic flux dynamics the

Functionalizing Injectable Hydrogels with Cobalt-Based Metallacarboranes for Targeted Delivery in Triple-Negative Breast Cancer. [PDF]

Chembiochem
This study reports a biocompatible HA–lysine hydrogel loaded with cobalt metallacarborane (CoSAN) for targeted release into triple‐negative breast cancer cells. The system maintains CoSAN cytotoxicity, as confirmed by cell assays and imaging, representing an attractive approach toward a localised TNBC treatment.

Improved Algorithms of Data Processing for Dispersive Interferometry Using a Femtosecond Laser

Sensors, 2023
Two algorithms of data processing are proposed to shorten the unmeasurable dead-zone close to the zero-position of measurement, i.e., the minimum working distance of a dispersive interferometer using a femtosecond laser, which is a critical issue in ...

Novel analysis tool for the distance of gold dimers controlled by the DNA strand length on the DNA origami. [PDF]

J Microsc
Abstract Metallic nanoparticle dimers have been used to enhance the excitation rate of single‐quantum emitters. The interparticle distance (d) of the dimers has a crucial influence on the signal enhancement. Therefore, precise control of d is desired for optimal performance. However, statistical analysis of d has been often restricted to a small number
