Abstract:
Vertically aligned nanocomposite (VAN) thin film has attracted tremendous research interests owing to its multifunctionality, enhanced physical properties and multi-field coupling. However, VAN has rarely been demonstrated in flexible form, which hinders its further application in flexible devices. In this work, La0.67Sr0.33MnO3-CeO2 (LC) VAN film has been deposited on flexible mica with or without a buffer layer. The LC nanocomposite films show high quality following textured growth and form a typical, vertically aligned nanostructure. Magnetic, transport and magnetoresistance properties have

This paper examines sensing mechanisms and stability issues of flexible sensors used in morphing wing applications.

Three-dimensional (3D) architectures of graphene are of great interest for applications in flexible electronics, supercapacitors, and biointerfaces.

Bilayers composed of graphene and polymeric film tightly adhere to each other and possess a sloped internal strain, which leads to spontaneous rolling to predetermined 3D microscale architectures.

Abstract:
Polyradicals – organic radical polymers in which each repeating unit contains a singly occupied molecular orbital (i.e. an unpaired electron spin) – are unique alternatives to their π-conjugated and semiconducting counterparts for several applications.[1] Unique of polyradicals are tunable charge states at their repeating units (see figure) which enable multi-stable charge transport regimes at the nanoscale. In this talk, we will present the use of thin films of polyradicals in transparent and flexible thin-film nanoelectronics. Although field-effect thin-film transistors (FETs) and flash memo

Abstract:
Recently, as research on developing electronic devices for simultaneous implementation of flexibility and conductivity has been continuously conducted, ensuring stable and high reliability of devices in preparation for various mechanical deformation is becoming important. When a physical force such as bending, twisting, or folding is applied, the bonding area between two substrates should ensure stability due to high stress generation. Epoxy resin materials used as standard adhesive agents have brittleness due to the nature of the material, and are weak in terms of flexibility due to increased

Backgrounds/Introduction Transition-metal dichalcogenides (TMDs) is an atomically-thin semiconducting material family, exhibiting unique physical and multi-functional properties. Despite the great promises in flexible electronics, the practical adoption of TMDs in a wider variety of far-reaching application domains, including high-temperature applications such as automobiles and aircrafts, still requires TMDs to be prepared at a larger scale and tailor-researched to the needs of a specific application. In this work, molybdenum disulfide (MoS2), one of the most widely studied TMD materials, is

Abstract:
To gain a competitive edge in developing innovative products, new multi-layer film manufacturers need to know whether laboratory-scale blown film line results reliably translate to large-scale production. This, however, is not always the case: Transferring process conditions and getting equal final film properties are not ensured. To address this problem, this paper presents a scale-independent scale-up/scale-down strategy to produce films with consistently similar properties regardless of a plant’s size and design.

Using methods of spatial nonlinear elasticity we consider the static stability of a rectangular two-layered plate. This problem has a peculiarity which relates to the appearance of nonhomogeneous initial stresses. Each layer of the plate was obtained as a result of straightening of the sector of a cylindrical shell. As a result we have the self-equilibrated initial stresses. The main aim of the paper is the analysis of these initial stresses on the pl ate buckling. The stability was analyzed with linearization method.

However, the optical transmittance of the GPG electrodes was degraded with increasing thickness of the Pt layer.
