A General and Efficient Framework for the Rapid Design of Miniaturized, Wideband, and High‐Bit RIS
Advanced Electronic Materials, EarlyView.A general and efficient framework is proposed for the rapid design of high‐performance reconfigurable intelligent surfaces (RISs). This framework integrates advanced antenna design techniques and incorporates various load types, quantities, and values to achieve the design of high‐performance RISs.

Persistent Homology Analysis of Graphene Surface Morphology Toward Carrier Mobility Evaluation
Advanced Electronic Materials, EarlyView.Persistent homology analysis is applied to understand the relationship between graphene surface morphology and carrier mobility. While arithmetic mean roughness fails to capture critical structural variations affecting carrier transport, our analysis leverages topological data from AFM images to uncover meaningful correlations.

Traps, Tail States and Their Consequences on the Open‐circuit Voltage in Organic Solar Cells
Advanced Energy Materials, EarlyView.It is found that the light‐intensity dependent low‐temperature roll‐off of open‐circuit voltage in organic solar cells is explained by the intrinsic disorder in these devices, which can be either described by the full Gaussian density of states or approximated by a two‐level system, which allows for a more intuitive interpretation.

Transport Resistance Dominates the Fill Factor Losses in Record Organic Solar Cells
Advanced Energy Materials, EarlyView.Organic photovoltaics are a promising solar cell technology, but even the record devices with 20% efficiency have significant fill factor losses due to low active layer conductivities. In this Perspective, the authors describe the origin of these losses, discuss experimental methods for their quantification, and explain how to minimize them to optimize

Dollars for Drops: Abatement Cost of Water for Irrigation in the Colorado River Basin
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT The Colorado River is a lifeline for more than 40 million people in the western United States. However, with climate change diminishing snowpacks in the Rocky Mountains and increasing demands from agriculture and urban areas, the river's flow has become insufficient to meet all the competing needs.

Beyond the Ban—Shedding Light on Smallholders' Price Vulnerability in Indonesia's Palm Oil Industry
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT The Indonesian government imposed a palm oil export ban in April 2022 to address rising cooking oil prices. This study explores oil palm smallholders' vulnerability to the policy using descriptive statistics, Lasso, and post‐Lasso OLS regressions.
