A Nigerian team built a reusable calcium oxide and aluminum oxide catalyst from snail shells that converted high-acid jatropha oil to biodiesel at 93.4 percent yield without acid pretreatment.
We’re sharing this article early to provide faster access to peer-reviewed, accepted research. It is citable and carries a permanent DOI. This version is subject to further edits and will be replaced automatically by the final…
The CNF/CMC composite films had an average Young’s modulus of 4.2 GPa, and suspended microbridges were as thin as 300 nm. Mechanically fibrillated CNFs were obtained from kenaf pulp through bleaching and repeated disk milling. TOCNFs were also prepared for comparison. TEMPO-mediated oxidation introduces carboxyl groups onto cellulose fiber surfaces.…

Researchers at the National Graphene Institute (NGI) at The University of Manchester have been awarded a £1.2 million (about US$1.6 million) Engineering and Physical Sciences Research Council (EPSRC) Standard Research Grant to…
Acoustic excitation provides a physical means of interrogating and modifying biological structures, yet the relationship between resonance, energy absorption and irreversible damage remains incompletely established. This…
Understanding how ions move through solid materials is key to advancing technologies such as batteries, fuel cells and sensors. A team of scientists led by the U.S. Department of Energy’s (DOE) Argonne National Laboratory has demonstrated a cutting-edge method for gauging the activity of ions, revealing a new level of…
EBSD mapping used a Symmetry S2 detector (Oxford Instruments) and TEM imaging was conducted on a JEM-2100F (JEOL). High-resolution STEM imaging was performed using the FEI Themis Z microscope equipped with an EDS detector. Atomic-resolution chemical characterization with compositional mapping was performed using four in-column Super-X silicon drift detectors. For…
Hydrogen could help industries reduce their dependence on fossil fuels, but its environmental benefits depend largely on how it is produced. Conventional hydrogen production can release substantial amounts of greenhouse gases…
