A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Does military spending affect inequality in South Africa? A revisit
Previous investigations on the military spending-inequality nexus (in South Africa) were underpinned by the assumption that military spending and inequality behaves in symmetric fashion and employed linear autoregressive distributed lag (ARDL) model in ...

Government spending shocks and the multiplier: New evidence from the U.S. based on natural disasters [PDF]
The literature on estimating macroeconomic effects of fiscal policy requires suitable instruments to identify exogenous and unanticipated spending shocks. So far, the instrument of choice has been military build-ups.

Binder‐free EGaIn–CB composite deliver printable, recyclable liquid‐metal conductors without sintering or polymer binders. Only 1.5 wt% CB yields shear‐thinning, high‐viscosity rheology, ∼60% bulk EGaIn conductivity, robust stretchability, high thermal conductivity, and strong EMI shielding (35 → 70 dB at 100% strain).

The demand for military expenditure in authoritarian regimes [PDF]
We investigate how the influence of the military differs across authoritarian regimes and verify whether there are actually systematic differences in military expenditures amongst different forms of dictatorships.
