Cent European J Urol. 2017; 70: 68 doi: 10.5173/ceju.2017.1316 Having received the opportunity to add my comments to this outstanding editorial represents for me a great honour and pleasure for two reasons. First, Dr. Giusti is a prominent figure in endourology and an enthusiastic teacher of supine PCNL, therefore forming an ideal academic partnership with Dr. Proietti in propagating this proce...

Superlattice Films Work function difference induces spontaneous charge donation and band bending at the interfaces of superlattices, which causes optimization effects modulation doping energy filtering, leading to remarkably enhanced thermoelectric performances. This optimizing strategy is successfully elucidated in 1T′-MoTe2/Bi2Te3 superlattice films. Meanwhile, rational manipulation interfaci...

The availability of high brilliance synchrotron sources, coupled with recent progress in achromatic focusing optics and large area 2D detector technology, have allowed us to develop a X-ray synchrotron technique capable of mapping orientation and strain/stress in polycrystalline thin films with submicron spatial resolution. To demonstrate the capabilities of this instrument, we have employed it...

Piezoresistance, the change of electrical resistance due to applied mechanical strain, has been characterized for films in tension or bending. However, measuring compressive piezoresistance remains a challenge because in-plane compression often results macroscopic buckling and kinking, leading localization strain. Here, we overcame this issue via newly developed method calculate by situ under t...

We fabricate high-performance, flexible, transparent electrochromic (EC) films and thin film heaters (TFHs) on an ITO/Cu/ITO (ICI) multilayer electrode prepared by continuous roll-to-roll (RTR) sputtering of ITO and Cu targets. The RTR-sputtered ICI multilayer on a 700 mm wide PET substrate at room temperature exhibits a sheet resistance of 11.8 Ω/square and optical transmittance of 73.9%, whic...

Silver nanowires (Ag NWs) are the promising materials to fabricate flexible transparent electrodes, aiming to replace indium tin oxide (ITO) in the next generation of flexible electronics. Herein, a feasible polyvinylpyrrolidone (PVP)-mediated polyol synthesis of Ag NWs with different aspect ratios is demonstrated and high-quality Ag NWs transparent electrodes (NTEs) are fabricated without high...

Surface properties canmarkedly affect themechanical behavior of structural thin films used inmicroelectromechanical systems (MEMS) applications. This study highlights the striking difference in the sidewall surface morphology of n+-type polysilicon films from two popular MEMS processes and its effect on fracture and fatigue properties. The sidewall surface roughness wasmeasured using atomic for...

Fracture toughness of La0.6Sr0.4Co0.2Fe0.8O3-δ (LSCF) in both bulk and film forms after sintering at 900°C to 1200°C was measured using both single-edge V-notched beam (SEVNB) 3-point bending and Berkovich indentation. FIB/SEM slice-and-view observation after indentation revealed the presence of Palmqvist radial crack systems after indentation of the bulk materials. Based on crack length measur...
