Probing the Architecture of Organic Heterojunctions Based on Zn(Salen)‐Type/Lu(Bis‐phthalocyanine) Complexes and Their Potential Application as Gas Sensors

Advanced Materials Interfaces, EarlyView.
Planar bilayer heterojunctions are fabricated from two molecular materials and compared to solution‐processed bulk heterojunctions. Raman spectroscopy and conductive AFM studies reveal the formation of conductive pillar‐like structures within a poorly conductive matrix.

Urea coated with poultry litter as an option in the control of nitrogen losses

Revista Brasileira de Engenharia Agrícola e Ambiental
The volatilization of ammonia (NH3) and nitrate leaching (NH3-) are the main processes of nitrogen (N) loss in the soil. The objective of the study was to evaluate N losses by NH3 volatilization and mineral N transformations in the soil with urea coated ...

A field-based comparison of ammonia emissions from six Irish soil types following urea fertiliser application

Irish Journal of Agricultural and Food Research, 2016
Ammonia (NH3) emissions from a range of soil types have been found to differ under laboratory conditions. However, there is lack of studies comparing NH3 emissions from different soil types under field conditions.

Nitrogen fluxes from irrigated common‑bean as affected by mulching and mineral fertilization

Pesquisa Agropecuária Brasileira, 2013
The objective of this work was to measure the fluxes of N2O‑N and NH3‑N throughout the growing season of irrigated common‑bean (Phaseolus vulgaris), as affected by mulching and mineral fertilization. Fluxes of N2O‑N and NH3‑N were evaluated in areas with

Spatially Configurable Conformal Sensor Integration on an Ultra‐Fine Metallic Needle for Minimally Invasive Deep‐Tissue Oxygen Monitoring

Advanced Materials Technologies, EarlyView.
A multi‐point oxygen‐sensing ultra‐fine needle (MO‐UFN) is developed by conformally integrating a lithographically patterned flexible electrochemical sensor array onto a clinical acupuncture needle. The platform preserves an approximately 0.3 mm diameter while enabling spatially resolved oxygen profiling along the insertion pathway.
