Data‐Driven Printability Modeling of Hydrogels for Precise Direct Ink Writing Based on Rheological Properties

open access: yesAdvanced Science, EarlyView.
A predictive model for 3D printability is developed by integrating rheological analysis, including the Large Amplitude Oscillatory Shear (LAOS) test, with machine learning. With prediction errors under 10%, the model shows that post‐extrusion recovery controls horizontal printability, while high‐strain‐rate nozzle flow dictates vertical printability ...

Ag Nanowire‐Integrated MoS2/ZnO Heterojunctions for Highly Efficient Photogenerated Charge Transfer

open access: yesAdvanced Electronic Materials, Volume 11, Issue 6, May 2025.
A versatile strategy is reported for fabricating multi‐dimensional heterojunctions with significantly improved charge transfer capability. By integrating Ag nanowires with a MoS2/ZnO heterojunction, a fourfold increase in surface photovoltage is achieved, reaching 200 mV under visible light illumination.

The Measured Black-White Wage Gap Among Women is Too Small [PDF]

open access: yes
Taken as a whole, the literature on black-white wage inequality suggests that racial gaps in potential wages are much larger among men than women, and further that one can accurately assess black-white gaps in potential wages among women without ...

King and Cochrane: The technological treadmill and racial inequity in US agriculture

open access: yesApplied Economic Perspectives and Policy, EarlyView.
Abstract Between 1920 and 1969, the number of Black farmers in the US decreased from 14% of all operators to 4%. Using Martin Luther King Jr.'s critique of agricultural policy and Willard Cochrane's theory of the technological treadmill, we explore how racial discrimination was linked to policies that led to structural change in US agriculture.

Perfluoroarene‐Based Tin Halide Perovskite Photovoltaics

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Herein, perfluoroarene cations, 2‐(perfluorophenyl)methylammonium (F‐BNA) and 1,4‐(perfluorophenyl)dimethylammonium (F‐PDMA), are applied to form layered Ruddlesden–Popper and Dion–Jacobson tin‐based perovskites. Following a detailed structural and optoelectronic characterization, a suitable solvent is identified and the perfluoroarenes are applied to ...
