Dense ZnO films with a strong c‐axis texture have been deposited on transparent conductive oxide glass, glass, and Si wafers, respectively, with a two‐step pressureless wet chemical method using zinc acetate dihydrate as Zn‐precursor. The cryst

A shape evolution approach based on the thermally activated self-organization of 3D printed parts into minimal surface area structures is presented. With this strategy, the present communication opposes currently established additive manufacturing st

Purpose This paper aims to present an additive manufacturing-based approach in which a new strategy for a thermally activated local melting and material flow, which results in densification of printed structures, is introduced. Design/methodology/app

The sinterability of K0.5Na0.5NbO3 (KNN) ceramics by a laser beam has been investigated in the present research. A 100 W CO2 laser with a beam diameter of 0.6 mm has been used to sinter the KNN specimens prepared on a uniaxial pressing machine. The r

The electromechanical characterization of carbon nanotube (CNT) papers, which are immersed in an aqueous electrolyte, is the main focus of this paper. The experimental set up consists of an ordinary three electrode cell, filled with the liquid electr

The paper starts with a discussion of the methods for the analysis of smart structures. A method is presented that does not require special finite elements for the analysis of structures with piezoelectric devices, but which uses conventional finite

Commonly, vibration isolation systems reduce the transmissibility from seismic base vibrations to sensitive structures. To obtain a desirable low isolation frequency, vibration isolation systems are typically equipped with low stiffness interfaces be

The success of active vibration control in adaptronics decisively depends on the performance of the actuators used as multifunctional structural elements. DLR’s concept of impedance matched actuators proposes novel actuators in honeycomb design (Fi
