Electric Field‐Induced Hole‐ and Electron‐Type Flat Bands in Twisted Double Bilayer Graphene

Advanced Electronic Materials, EarlyView.
The electronic structure of twisted double bilayer graphene is visualized using angle‐resolved photoemission spectroscopy with micrometer spatial resolution at twists of 3.1∘$^\circ$ and 6.0∘$^\circ$ as a function of gate voltage. Tunable hybridization effects and flat band formation occurs between valence and conduction band states due to a finite ...

Quantifying Evolving Defect Parameters in Metal Halide Perovskites via the Measurement and Modeling of Power‐Dependent Transient Photoluminescence

Advanced Energy Materials, EarlyView.
ABSTRACT Dynamic photoinduced defect states in metal halide perovskites (MHPs) critically govern the non‐equilibrium photophysics, metastability, and long‐term performance of optoelectronic devices, such as solar cells. This metastability is evident in steady‐state photoluminescence experiments, where the amplitudes increase or decrease depending on ...

Toward Standardization in CO2 Electrolysis: A Round Robin Study

Advanced Energy Materials, EarlyView.
CO2 electrolysis is a promising green technology for producing fuels and chemicals. To support its real‐world adoption, researchers conducted a collaborative study to identify sources of experimental variability. They found key differences in temperature and pressure control across labs and proposed a standardized testing protocol to improve ...

Something Rational in the State of Denmark? The Case of an Outsider in the Cobden-Chevalier Network 1860-1875 [PDF]

We examine the case of an important outsider to the Cobden-Chevalier network of bilateral treaties in the second half of the nineteenth century. We attempt to explain this through a study of the structure of Danish trade and protection.

Livestock Tango: U.S. and Latin America Dance Together, but Who Will Lead?

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT This study examines the competitiveness between Latin American and U.S. livestock and meat sectors. We employ a computable general equilibrium modeling framework to evaluate two scenarios: coordinated improvements in Latin American productivity, transport efficiency, and market access (Scenario I), and the minimum productivity gains required ...

Financial Integration and Consumption Comovements in the Nordic Countries [PDF]

The cross-country correlations between annual per capita consumption growth in the Nordic countries (Denmark, Finland, Norway and Sweden) during the period 1973-1996 are much lower than predicted by the basic theory of international financial integration.

Sustainable Productivity Growth in Agriculture: The Role of Shifts in R&D Investments and Technology

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT The objective of the paper is to evaluate the long‐term prospects of sustainable productivity growth linked to plausible assumptions on public agricultural R&D investments as the key productivity driver. Second, it investigates the role of changing R&D focus from yield maximization to input saving technologies (fertilizers and pesticides). The

Impact of Deprescribing Among Older Adults in Primary Care Settings: A Systematic Review and Meta‐Analysis of Randomized Controlled Trials

AGING MEDICINE, EarlyView.
Deprescribing interventions in primary care modestly reduce medication burden, patient falls, and hospitalisations among older adults, highlighting the value of medication reviews and collaborative care strategies. ABSTRACT Background Deprescribing is a systematic approach aimed at reducing the number of medications that are no longer beneficial or ...
