Scale-Specific Viscoelastic Characterization of Hydrogels: Integrated AFM and Finite Element Modeling. [PDF]

Small
An integrated multiscale approach reveals distinct viscoelastic responses of hydrogels across length scales. Combining AFM‐based nanoindentation, finite element modeling, and a novel analytical framework, this study enables accurate, scale‐specific mechanical characterization to guide the design of advanced biomaterials. Abstract Viscoelastic hydrogels

A MEMS viscometer for unadulterated human blood [PDF]

, 2010
The design and theoretical modelling of an oscillating micro-mechanical-viscometer designed for the measurement of whole unadulterated human blood, is described. The proposed device utilises the dependence of the squeeze-film damping ratio on properties

Meissner Effect and Nonreciprocal Charge Transport in Non-Topological 1T-CrTe₂/FeTe Heterostructures. [PDF]

Adv Mater
This work demonstrates interface‐induced superconductivity (Tc ∼12 K) with a robust Meissner effect and pronounced nonreciprocal transport in epitaxial 1T‐CrTe2/FeTe heterostructures, where 1T‐CrTe2 is a 2D ferromagnet, and FeTe is an antiferromagnetic metal.

Variational approach to relaxed topological optimization: closed form solutions for structural problems in a sequential pseudo-time framework [PDF]

, 2019
The work explores a specific scenario for structural computational optimization based on the following elements: (a) a relaxed optimization setting considering the ersatz (bi-material) approximation, (b) a treatment based on a non-smoothed characteristic
