Thickness measurement of thin films using atomic force microscopy based scratching Open
Thin-film thickness measurements using atomic force microscopy (AFM) comprise two steps: 1. AFM scratching in order to produce an exposed film edge, and 2. subsequent AFM measurement of the corresponding step height across the exposed edge…

Electrically tunable terahertz transmission modulators using metal–insulator–metal metasurfaces infiltrated with liquid crystals Open
Using numerical calculations, we present the design of terahertz transmission modulators based on transmissive metal–insulator–metal metasurfaces, which consist of two planar arrays of parallel metallic ribbons while the deeply-subwaveleng…

Local photocurrents in two dimensional materials measured by conductive atomic force microscopy Open
Local photocurrents are commonly measured by photoconductive atomic force microscope (PC-AFM) which consists of standard conductive AFM (C-AFM) coupled with an external light source. Here we demonstrate that even basic C-AFM setup without …

Two-dimensional talc as a van der Waals material for solid lubrication at the nanoscale Open
Talc is a van der Waals and naturally abundant mineral with the chemical formula Mg 3 Si 4 O 10 (OH) 2 . Two-dimensional (2D) talc could be an alternative to hBN as van der Waals dielectric in 2D heterostructures. Furthermore, due to its g…

Partial ablation of Ti/Al nano-layer thin film by single femtosecond laser pulse Open
The interaction of ultra-short laser pulses with Titanium/Aluminium (Ti/Al) nano-layered thin film was investigated. The sample composed of alternating Ti and Al layers of a few nanometres thick was deposited by ion-sputtering. A single pu…

Biomembranes from slaughterhouse blood erythrocytes as prolonged release systems for dexamethasone sodium phosphate Open
The present study investigated preparation of bovine and porcine erythrocyte membranes from slaughterhouse blood as bio‐derived materials for delivery of dexamethasone‐sodium phosphate (DexP). The obtained biomembranes, i.e., ghosts were c…

Enhanced structural stability of DNA origami nanostructures by graphene encapsulation Open
We demonstrate that a single-layer graphene replicates the shape of DNA origami nanostructures very well. It can be employed as a protective layer for the enhancement of structural stability of DNA origami nanostructures. Using the AFM bas…
