Bacterial cellulose-lignin composite hydrogel as a promising agent in chronic wound healing
(Elsevier, Amsterdam, 2018)
Lignins and lignin-derived compounds are known to have antibacterial properties. The wound healing agents in the form of dressings produce faster skin repair and decrease pain in patients. In order to create an efficient ...
Application of Nanocrystalline Pseudobrookite (Fe2TiO5) Thick Films for Humidity Sensing
(IEEE Computer Society, 2018)
Pseudobrookite nanocrystalline thick films were screen printed on alumina substrate with small interdigitated PdAg electrodes (width 6 mm, length 12 mm, electrode spacing 0.2 mm) and fired at 600 degrees C for 30 minutes. ...
Ordering effect of kinetic energy on dynamic deformation of brittle solids
(Elsevier, 2008)
The present study focuses on the plane strain problem of medium-to-high strain-rate loading of an idealized brittle material with random microstructure. The material is represented by an ensemble of “continuum particles” ...
Some Observations Regarding Stochasticity of Dynamic Response of 2D Disordered Brittle Lattices
(SAGE Publications, 2011)
It had been long recognized that the tensile strength of brittle materials
increases with increase of the loading rate. In the present article, a statistical
approach to rupture of a disordered 2D triangular truss lattice ...
Damage-fragmentation transition: Size effect and scaling behavior for impact fragmentation of slender projectiles
(SAGE Publications, 2018)
The focus of the present article is on the size effect of a transition region from the damaged to the fragmented phase in impact-induced breakup of a slender projectile. Molecular dynamics simulations of the classic ballistic ...
Analysis of electronic properties of pseudobrookite thick films with possible application for NO gas sensing
(IEEE Computer Society, 2016)
Two pseudobrookite (PSB) containing pastes were composed of a mixture of starting nanopowders of hematite (alpha-Fe2O3) and anatase (TiO2) in the molar ratios 1: 1 (referred to as PSB-1) and 1:1.5 (referred to as PSB-1.5), ...
A Note on Short-time Response of Two-dimensional Lattices during Dynamic Loading
(SAGE Publications, 2008)
The disordered 2D lattices are used extensively to study damage
evolution and fracture of inhomogeneous or multi-phase systems. The present note
addresses their initial elastic response during dynamic loading. Namely, a ...
Molecular-dynamics simulations of the nanoscale Taylor test under extreme loading conditions
(SAGE Publications, 2016)
A series of molecular-dynamics simulations of the classic Taylor impact test is performed by using a flat-ended monocrystalline nanoscale projectile made of the Lennard-Jones two-dimensional solid. The nanoprojectile ...
On strain-rate sensitivity and size effect of brittle solids: transition from cooperative phenomena to microcrack nucleation
(Springer Nature, 2013)
An idealized brittle microscale system is subjected to dynamic uniaxial tension in the medium-tohigh
strain-rate range (˙ε ∈ [100 s−1, 1×107 s−1]) to investigate its mechanical response under constrained
spatial and ...
Impact fragmentation of nanoscale projectiles at ultrahigh striking velocities
(Springer Nature, 2015)
Molecular-dynamics simulations of the
classic Taylor experiment are performed to investigate
some general trends of impact fragmentation at ultrahigh
striking velocities. The striking velocities of flatended,
monocrystalline, ...
