Role of the Recombination Zone in Organic Light‐Emitting Devices

Advanced Materials, EarlyView.
This review summarizes the critical role of the recombination zone in organic light‐emitting diodes (OLEDs). We highlight that broadening the recombination zone in OLEDs based on emissive layers with balanced charge transport and high photoluminescence quantum yields provides a promising route toward achieving both long operational lifetime and high ...

Three Years After Soybean-Cover-Crop Rotation in Conventional and No-Till Practices: What Are the Consequences on Soil Nitrous Oxide Emissions?

Nitrogen
Nitrous oxide is a potent greenhouse gas due to its long atmospheric lifespan (121 years) that results in a high global warming potential (GWP). Research has shown that no-tillage may be implemented as a mitigation strategy to reduce N2O emissions.

Share of anthropophytes in the crop sequence: winter wheat – maize – spring wheat depending on tillage system

Acta Agrobotanica, 2014
An experiment, conducted over the period 2008–2010, evaluated the effect of tillage system on the occurrence and species composition of anthropophytes in winter wheat, maize and spring wheat.

An Economic Analysis of Carbon Sequestration for Wheat and Grain Sorghum Production in Kansas [PDF]

This study examined the economic potential with and without carbon credit payments of two crop and tillage systems in South Central Kansas that could reduce carbon dioxide emissions and sequester carbon in the soil. Experiment station cropping practices,

Genetic variation for nutrient use efficiency in maize under different tillage and fertilization regimes with special emphasis to plant microbe interaction [PDF]

, 2010
Conservation tillage (no-till and reduced tillage) brings many benefits with respect to soil fertility and energy use, but it also has drawbacks regarding the need for synthetic fertilizers and herbicides.

Two‐Photon 3D Printing of Functional Microstructures Inside Living Cells

Advanced Materials, EarlyView.
This study demonstrates 3D printing inside living cells by using two‐photon photo‐lithography. A bio‐compatible photoresist is injected into cells and selectively polymerized with a femtosecond laser, creating custom‐shaped intracellular structures with submicron resolution.

Cover Crop Termination & Reduced Tillage Study [PDF]

, 2012
When a crop such as corn silage is harvested in the fall, the entire plant is removed leaving the soil exposed through the winter. These exposed soils are more prone to run-off and erosion of sediment and nutrients into surface waters.

Nonmulberry Silk Fibroin Doping Boosts Charge Transfer and Charge Injection in Aligned Polypyrrole‐Silk Scaffolds for Low‐Voltage Neurostimulation

Advanced Materials Interfaces, EarlyView.
Conductive silk‐polypyrrole scaffolds couple redox stability with cell‐affinitive peptides present innately in an endogenous silk fibroin, enabling optimized electrical stimulation to drive neurite outgrowth. Findings establish electrochemical‐biological link for biomaterial design rules for smart nerve guidance conduits that can provide low voltage ...

Residue management induced changes in soil organic carbon and total nitrogen under different tillage practices in the North China Plain

Journal of Integrative Agriculture, 2019
Crop residue retention has been considered a practicable strategy to improve soil organic carbon (SOC) and total nitrogen (TN), but the effectiveness of residue retention might be different under varied tillage practices.
