Effect of Cold Rolling on Microstructure and Mechanical Properties of a Cast TiNbZr-Based Composite Reinforced with Borides

Metals
The TiNbZr/(Ti, Nb)B metal matrix composite with 2.5 vol.% of borides was produced by vacuum arc melting. The composite was then cold-rolled to thickness strains of 10, 20, 50, or 80%.

Knock phenomenon analysis on a diesel-CNG dual fuel engine using experimental fuel ratio [PDF]

, 2021
Knock avoidance is crucial to establish a proper Diesel-CNG Dual Fuel (DDF) engine. The causes of this phenomenon are still vague due to the lack of knock detection and characterization methods available.

In-Situ Spectroelectrochemical Study of Conductive Polyaniline Forms for Sensor Applications

Proceedings, 2020
Our contribution focuses on a correlative study of polyaniline (PANI) electropolymerisation and UV/VIS spectroscopy. PANI was prepared via electro-oxidation using a potentiodynamic method on commercial gold screen-printed electrodes (Au-SPE). By using an

The glycocalyx affects the mechanotransductive perception of the topographical microenvironment

Journal of Nanobiotechnology, 2022
The cell/microenvironment interface is the starting point of integrin-mediated mechanotransduction, but many details of mechanotransductive signal integration remain elusive due to the complexity of the involved (extra)cellular structures, such as the ...

Biocompatibility, Corrosion Resistance, and Wear Resistance of TiNbZr-Based Composites Reinforced with Borides

Metals
TiNbZr-(Ti,Nb)B composites were produced by vacuum arc melting; the weights of TiB2 in the charge mixture were 0.7 wt. % (Alloy A) and 4.0 wt. % (Alloy B). In addition, unreinforced TiNbZr alloy specimens were fabricated without the addition of TiB2. The
