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 ...

The social value of science shops: A cost-benefit analysis

open access: yesApstract: Applied Studies in Agribusiness and Commerce, 2012
We describe and apply a method to determine the net social benefits of science shops. University departments operating as science shops coordinate research projects for individuals or civil society organizations (CSO) lacking the financial means to turn ...

Magnetic Anisotropy Modulation via van der Waals Gap Engineering in 2D Ferromagnet Fe4GeTe2

open access: yesAdvanced Science, EarlyView.
This study demonstrates a new route to control magnetic anisotropy in 2D ferromagnets via van der Waals gap engineering. In Fe4GeTe2, an interface‐induced vdW gap expansion is found to anomalously enhance in‐plane magnetic anisotropy while suppressing the spin reorientation transition.

Coupling Nitrogenous Organic Wastewater Treatment and Biorefinery via N‐Cycling Bacterium

open access: yesAdvanced Science, EarlyView.
The vast reservoir of nitrogenous organic pollutants in industrial wastewaters can serve as untapped carbon‐nitrogen resources. This study employs the newly discovered Paracoccus sp. ZQW‐1 as a versatile chassis to simultaneously achieve N‐methylpyrrolidone (NMP) wastewater depuration and polyhydroxybutyrate (PHB) synthesis.

A Perspective on the Applications of Triphasic Gas Storage in Electrochemical Systems

open access: yesAdvanced Science, EarlyView.
Gas storage in microporous materials positioned locally at an electrode or electrocatalyst surface enhances electrochemical processes. Abstract Microporous materials store gases under dry conditions (e.g., hydrogen or oxygen via physisorption), but in some cases microporous materials also show triphasic (e.g., in a solid|gas|liquid system) gas storage ...

Impact of NAFTA on U.S. and Mexican Sugar Markets

open access: yesJournal of Agricultural and Resource Economics, 2015
When NAFTA became fully implemented for sugar in 2008, Mexico became the leading sugar exporter into the United States, accounting for nearly 70% of U.S. imports in 2013.

Efficiency Recalibrates Social‐Emotional Trade‐Offs Behind Partner Choice in Direct Reciprocity through Intention‐Specific Neural Bases

open access: yesAdvanced Science, EarlyView.
Bridging the gap between two crucial mechanisms of cooperation, namely direct reciprocity and partner choice, this study reveals the neurocognitive bases underlying how individuals prioritize reciprocal partner when receiving help from multiple benefactors with diverse intentions and reciprocal efficiency. The efficiency‐driven reciprocal decisions are
