Solution processed silver nanowire meshes (Ag NWs) were laminated on top of solid-state dye-sensitized solar cells (ss-DSCs) as a reflective counter electrode. Ag NWs were deposited in <1 min and were less reflective compared to evaporated Ag controls; however, AgNW ss-DSC devices consistently had higher fill factors (0.6 versus 0.69), resulting in comparable power conversion efficiencies (2.7%...

Abstract In this paper a broadband active shunt technique for controlling vibration in piezoelectric laminated structures is proposed. The effect of the negative capacitance controller is studied theoretically and then validated experimentally on a piezoelectric laminated simply supported plate. The ‘negative capacitance controller’ is similar in nature to passive shunt damping techniques, as a...

background: development of biodegradable and biocompatible films based on protein polymer with strong antioxidant and antibacterial activities has gradually obtained extensive concern in the world. in this study, the improvement of gelatin film properties incorporated with ferula assa-foetida essential oil (fao) as a potential antioxidant/antibacterial wound dressing film was investigated. mate...

Abstract: Excellent thermal conductivities of management materials are expected to ensure the timely heat dissipation in lots engineering applications and electronic devices. High in-plane conductivity laminated composites has become increasing significant for high energy power density In this study, continuous graphite film/aluminum (Gr film/Al) were fabricated by vacuum hot pressing. In-plane...

Zn0.97TM0.03O (TM = Co, Fe) thin films were deposited onto glass substrates by the sol–gel method and the effects of transition metals substitution on structural and optical properties of ZnO films were investigated. The X-ray diffraction patterns revealed that the films have wurtzite structure. Optical transmittance of the films was recorded in the range of 200 -800 nm wave length and the band...

Abstrsct Polymorphic Hf x Zr (1− ) O 2 thin films have been widely used as dielectric layers in the semiconductor industry for their high- k , ferroelectric, and antiferroelectric properties metastable non-monoclinic phases. To maximize components, we optimize composition depth profile of 20 nm PVD through closed-loop experiments by using parallel Bayesian optimization (BO) with advanced noisy ...

It is well known that for laminated composite plates a Levy-type solution exists only for cross-ply and antisymmetric angle-ply laminates. Numerous investigators have used the Levy method to solve the governing equations of various equivalent single-layer plate theories. It is the intension of the present study to introduce a method for analytical solutions of laminated composite plates with ar...

Nano-TiO2 is widely used as a commercial food contact material (FCM), which poses potential risks to food. Therefore, the migration of TiO2 crucial for safety FCM. Since PET/TiO2 composite films are layers producing polymer-laminated steel cans and majority beverages contained in acidic, it necessary study from acidic solutions. The 4% (v/v) acetic acid was studied through ICP-OES method. corro...

In this article, free vibration analysis of variable stiffness composite laminate (VSCL) plates with flat and folded shapes is studied. In order to consider the concept of variable stiffness, in each layer of these composite laminated plates, the curvilinear fibers are used instead of straight fibers. The analysis is based on a semi-analytical finite strip method which follows classical laminat...
