STUDY OF INTERNAL NANOPOROUS STRUCTURE AND EXTERNAL SURFACE OF BIMETALLIC NANOPARTICLES
Физико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2020 Exemplifying on two bimetallic nanoparticles Cu — Pt and Au — Ag, the internal structure and external surface has been investigated in the process of dealloying. Equiatomic compositions with the total number of atoms Ntot = 3000 are considered.

Spheroid Cell Aggregation Enhanced by Enzyme‐Free Ultrasound‐Detached Cells
Advanced Biology, EarlyView.This study demonstrates that ultrasound‐based, enzyme‐free cell detachment accelerates spheroid formation by preserving surface proteins, reducing variability, and enhancing cell aggregation. Comparable engraftment and improved spatial organization in co‐cultured spheroids are observed.

Directional Lower Porosity [PDF]
Real Analysis Exchange, 2014 We investigate differences between upper and lower porosity. In finite dimensional Banach spaces every upper porous set is directionally upper porous. We show the situation is very different for lower porous sets; there exists a lower porous set in the plane which is not even a countable union of directionally lower porous sets.

Advanced Biology, EarlyView.The glomerular filtration barrier (GFB) is the first step of blood filtration by the kidneys. The concerning increase of kidney diseases makes the development of new models essential. In this context, microphysiological glomerular filtration barriers focus on closely reproducing the physiological architecture of the in vivo GFB: podocytes, glomerular ...
