A comprehensive study on flash sintering of anatase and rutile polymorphs-containing titania nanopowder: Phase and microstructure development

open access: yesJournal of Advanced Ceramics
Flash sintering has proven to be a novel and cost-efficient technique that enables the successful processing of dissimilar materials. The present work investigated how sintering under electric field input progresses in commercial anatase (A) plus rutile (

High Temperature Oxidation of Nickel-based Cermet Coatings Composed of Al2O3 and TiO2 Nanosized Particles

open access: yesHigh Temperature Materials and Processes, 2014
New technological challenges in oil production require materials that can resist high temperature oxidation. In-Situ Combustion (ISC) oil production technique is a new method that uses injection of air and ignition techniques to reduce the viscosity of ...

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

open access: yesFEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

A numerical investigation of constant-volume non-Boussinesq density currents [PDF]

open access: yes, 2010
The time-dependent behaviour of non-Boussinesq high-Reynolds-number density currents of density ρc, released from a lock of height h₀ and length x₀ into a ambient of height H and density ρₐ, is considered. We use two dimensional Navier-Stokes simulations

Experimental realization of induced current magnetic resonance current density imaging

open access: yes, 2015
In this paper, recently proposed Induced Current Magnetic Resonance Current Density Imaging (ICMRCDI) is experimentally realized. The reconstructed current density images from the simulated measurements and from the physical measurements are in agreement.

Interactions between hyaluronic acid and CoCrMo alloy surface in simulated synovial fluids

open access: yesBiosurface and Biotribology, 2021
The performance of CoCrMo alloy in orthopaedic implants may be unfavourably affected by hyaluronic acid (HA) in synovial fluid. In this study, the authors aimed to understand the interactions between HA and CoCrMo using dedicated electrochemical ...

Structure‐forward targeting of claudins with synthetic binders

open access: yesFEBS Letters, EarlyView.
Claudins form the paracellular barriers between epithelial and endothelial tissues at tight junctions and are targets for molecular binders with the goal of modulating barrier permeability. Claudin‐binding molecules are relevant in drug delivery or in altering claudin interactions with disease‐causing proteins.

Distorted Modeling of Density Currents

open access: yesCoastal Engineering 1972, 1972
The paper describes a method of choosing scales for the correct representation of convective spread in a hydraulic model involving densimetric phenomena. Although most prototype spreads are non-viscous in nature it is possible for small scale laboratory spreads to become affected by viscous influence when the spreading density front is remote from the ...

Comparison of exact-exchange calculations for solids in current-spin-density- and spin-density-functional theory [PDF]

open access: yes, 2007
The relative merits of current-spin-density- and spin-density-functional theory are investigated for solids treated within the exact-exchange-only approximation.
