Studying the Effect of Transport Layers on ZrS2/MEH-PPV Solar Cells: Using SCAPS -1D Software
East European Journal of PhysicsThis study investigates the effect of charge transport layers on the efficiency of Poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH_PPV) and Zirconium Disulfide (ZrS₂) solar cells using Scaps-1D software. It was found that by increasing the

A hierarchy of functional states in working memory [PDF]
The Journal of Neuroscience, 2020 Abstract Extensive research has examined how information is maintained in working memory (WM), but it remains unknown how WM is used to guide behaviour. We addressed this question by combining human electrophysiology with pattern analyses, cognitive modelling, and a task requiring maintenance of two WM items and priority shifts between ...

Hollow cathode life-time prediction from low work function surface coverage evolution [PDF]
, 2008 In this paper a procedure to update the plasma parameters relatively to changes of the hollow cathode surface work function has been developed. This procedure has been validated with experimental results and then coupled with the deposition/desorption ...

Defects in oxide surfaces studied by atomic force and scanning tunneling microscopy
Beilstein Journal of Nanotechnology, 2011 Surfaces of thin oxide films were investigated by means of a dual mode NC-AFM/STM. Apart from imaging the surface termination by NC-AFM with atomic resolution, point defects in magnesium oxide on Ag(001) and line defects in aluminum oxide on NiAl(110 ...

Rayleigh’s dissipation function at work [PDF]
European Journal of Physics, 2015 It is shown that the Rayleigh's dissipation function can be successfully applied in the solution of mechanical problems involving friction non-linear in the velocities. Through the study of surfaces at contact we arrive at a simple integral expression which gives directly the Rayleigh dissipation function in terms of generalized coordinates.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Children with sickle cell disease (SCD) face multiple acute and chronic medical complications that may impact their quality of life as reported by patients themselves. Health‐related social needs (HRSNs), such as food and housing insecurity, are common in people with SCD, but the association between HRSNs and patient‐reported ...
