A SYNERGY CODE IN CO-PYROLYSIS; pp. 471–490 [PDF]

Oil Shale, 2013
For the first time, a mathematical model has been proposed to describe the influence of blending ratio on the synergy in co-pyrolysis. The model is based on the stability of a new cross-compound AnB formed between the pyrolysis products of the blend ...

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Dynamics of residential water-soluble organic gases: Insights into sources and sinks

Environmental Science and Technology, 2019
Water-soluble organic gas (WSOG) concentrations are elevated in homes. However, WSOG sources, sinks, and concentration dynamics are poorly understood. We observed substantial variations in 23 residential indoor WSOG concentrations measured in real time ...

The Role of Arbuscular Mycorrhizal Fungi in Enhancing Productivity, Nutritional Quality, and Drought Tolerance Mechanism of Stylosanthes seabrana

Media Peternakan, 2012
Arbuscular Mycorrhizal Fungi (AMF) is a symbiotic association between plant roots and fungi. Their major role is to enhance nutrient and water uptake by the host plants.

Characterization of aerosol and cloud water at a mountain site during WACS 2010: secondary organic aerosol formation through oxidative cloud processing [PDF]

Atmospheric Chemistry and Physics, 2012
The water-soluble fractions of aerosol filter samples and cloud water collected during the Whistler Aerosol and Cloud Study (WACS 2010) were analyzed using an Aerodyne aerosol mass spectrometer (AMS). This is the first study to report AMS organic spectra

Liquid Phase Transmission Electron Microscopy: A Window into the Early Stages of Complex Material Formation

Advanced Functional Materials, EarlyView.
Liquid‐phase transmission electron microscopy enables direct observation of nucleation and growth processes in solution. This review is dedicated to the remembrance of Helmut Cölfen and highlights recent studies on complex materials—oxides, biominerals, organic–inorganic crystals—which were central to his research activity. It summarizes key milestones,

Hydrochemical and isotopic (δ18O, δ2H, 87Sr/86Sr, δ37Cl and δ81Br) evidence for the origin of saline formation water in a gas reservoir

, 2014
The Permo-Triassic Kangan gasfield in southern Iran is composed of an aquifer, the Kangan Aquifer (KA), and an overlying gas reservoir. It is located in the Kangan and Dalan Formations and consists predominantly of limestone and dolomite.
