Using the Photostationary State of Arylazopyrazoles to Control Phase Transitions of Liquid Crystals

open access: yesAdvanced Functional Materials, EarlyView.
A series of new arylazopyrazole photoswitches is designed as dopants for liquid crystalline materials. Unprecedented, the distribution of photoisomers at the photostationary state upon irradiation with light of specific wavelengths (365, 460, 520 nm) is used to control the liquid crystalline phase transitions under isothermal conditions, including ...

Astrocyte‐Guided Maturation of Neural Constructs in a Modular Biosynthetic Hydrogel for Biohybrid Neurotechnologies

open access: yesAdvanced Functional Materials, EarlyView.
A modular biosynthetic PVA–gelatin hydrogel crosslinked via visible‐light thiol‐ene chemistry is engineered as a coating for neural electrodes. Optimizing matrix composition and mechanical properties enables the hydrogel to support astrocytic populations that guide neural differentiation and functional maturation.

Toward Scalable Solutions for Silver‐Based Gas Diffusion Electrode Fabrication for the Electrochemical Conversion of CO2 – A Perspective

open access: yesAdvanced Functional Materials, EarlyView.
In this study, the preparation techniques for silver‐based gas diffusion electrodes used for the electrochemical reduction of carbon dioxide (eCO2R) are systematically reviewed and compared with respect to their scalability. In addition, physics‐based and data‐driven modeling approaches are discussed, and a perspective is given on how modeling can aid ...

Infiltration and short-term movement of nitrogen in a silt-loam soil typical of rice cultivation in Arkansas [PDF]

open access: yes, 2006
Rice production in Arkansas is one of the top three crop commodities in terms of cash receipts. Researchers and farmers report that nitrogen (N) needs to be managed according to a variety of factors with two important ones being soil and fertilizer type.

Dimethyl sulfate and diisopropyl sulfate as practical and versatile O-sulfation reagents

open access: yesNature Communications
AbstractO-Sulfation is a vital post-translational modification in bioactive molecules, yet there are significant challenges with their synthesis. Dialkyl sulfates, such as dimethyl sulfate and diisopropyl sulfate are commonly used as alkylation agents in alkaline conditions, and result in the formation of sulfate byproducts.

Bio‐Inspired Nanoarchitected LiFePO4 Cathodes

open access: yesAdvanced Functional Materials, EarlyView.
Lithium iron phosphate (LFP) is synthesized using a bio‐inspired method, using acidic macromolecules similar to those found in many calcareous mineralized organisms to modulate the morphology and crystal growth of LFP‐carbon composite particles. The observations from this process indicate a non‐classical crystallization process, which subsequently ...

Southern Annular Mode response to volcanic eruptions: implications for ice core proxies [PDF]

open access: yes, 2011
Large tropical volcanic eruptions have been observed to have a significant influence on the large-scale circulation patterns of the Northern Hemisphere, through mechanisms related to the radiative effects of the sulfate aerosols resulting from the ...
