Role of the Recombination Zone in Organic Light‐Emitting Devices

Advanced Materials, EarlyView.
This review summarizes the critical role of the recombination zone in organic light‐emitting diodes (OLEDs). We highlight that broadening the recombination zone in OLEDs based on emissive layers with balanced charge transport and high photoluminescence quantum yields provides a promising route toward achieving both long operational lifetime and high ...

Bipolarity and War: The Role of Capability Concentration and Alliance Patterns among Major Powers, 1816-1965 [PDF]

, 1984
This paper examines the relationship of war to power concentration and alliance configuration among the major powers. It does so by developing a theoretical argument from the literature on bipolarity and multipolarity.

Single‐Chromophore Homojunction Organic Solar Cells: A Path to Simplicity and Efficiency

Advanced Materials, EarlyView.
This perspective discusses how the intrinsic optoelectronic properties of organic semiconductors, their molecular packing in the solid‐state, and internal energetic gradients within a device can enable free‐charge carrier generation in homojunction organic solar cells.

A study of incidence of bipolar disorder in patients treated for major depression

Telangana Journal of Psychiatry, 2019
Aim: Recurrent episodes of depression are common in both unipolar and bipolar disorder, but diagnostic and clinical problem with bipolar mood disorder is that hypomanic episodes usually go unnoticed by caretakers and clinicians.

Direct Growth of 2D Bilayers on Au(111) for Low‐Coercive Sliding Ferroelectricity

Advanced Materials, EarlyView.
Controlled CVD growth of stacking‐defined bilayer ReS2 on Au(111) enables parallel‐stacked bilayers with intrinsic sliding ferroelectricity, a strong piezoelectric response, and an ultralow coercive voltage. Atomic‐resolution imaging and in situ measurements further reveal the decisive role of clean interfaces in achieving low‐barrier ferroelectric ...
