Insulating‐Passivating Interfaces for Narrow‐Bandgap Tin‐Lead Perovskites Enable High‐Photovoltage in Single‐ and Double‐Junction Solar Cells

Advanced Functional Materials, EarlyView.
Combining field‐effect surface passivation of a narrow‐bandgap tin–lead perovskite by diammonium ions with introducing oleyl‐based amphiphiles to create insulating interface layers between the absorber and the adjacent hole and electron transporting layers increases the open‐circuit voltage to 91.5% of the detailed‐balance limit and enhances the power ...

A Miniaturized Autonomous Thermomagnetic Generator

Advanced Functional Materials, EarlyView.
Micro, autonomous and high power thermomagnetic generator operating between a heat dissipator and a processor. ABSTRACT Thermomagnetic generators (TMG) are promising devices for converting low‐grade waste heat into electricity. Self‐actuation using permanent magnets is the key to autonomy.

Programming Neuromorphic Plasticity Through Ionic and Electronic Coupling in Organic Electrochemical Transistors

Advanced Functional Materials, EarlyView.
Neuromorphic plasticity in OECTs is governed by the post‐stimulus evolution of coupled ionic and electronic states. Semiconductor chemistry and morphology, electrolyte composition and interfaces, and device architecture regulate ion injection, transport, confinement, and release, shifting responses from rapidly relaxing STP to metastable memory and ...

Semen analysis

, 2011
Abstract Semen analysis remains the most important diagnostic tool for the study of male infertility to date. For this reason, and because of the ease of carrying out this analysis, examination of seminal fluid should be among the first diagnostic steps in cases of suspected infertility, prior to subjecting the man’s partner to long and ...

Semen Analysis

Urologic Clinics of North America, 1987
The capability to analyze semen is not new but until recently was a clinical art practiced well by only a few experts. The development of objective, quantitative methods for semen evaluation has brought these diagnostic capabilities to every clinical laboratory. These methods are described, and an interpretation of semen parameters is presented for the

Human semen analysis

Human Reproduction Update, 1995
Rapid developments have occurred in the management of couple infertility due to a male factor. These have stimulated renewed interest in semen analysis, which has become more correct, more reliable and more informative. The so-called basic semen analysis, which includes subjective estimation of sperm concentration, motility and morphology, has largely ...
