    “…Based on samples of the Oman Drilling Project, here we show that listvenites with a penetrative foliation have abundant microstructures indicating that the carbonation reaction occurred during deformation. Folded magnesite veins mark the onset of carbonation, followed by deformation during carbonate growth. …”

    “…The objective of this work is to develop and demonstrate the filtration and dewatering of kerosene using a carbon nanotube immobilised membrane (CNIM). Highly hydrophobic membranes were prepared by immobilising carbon nanotube (CNTs) over polytetrafluoroethylene (PTFE) and polyvinylidene difluoride (PVDF) microfiltration membrane for the dewatering of ppm level water from kerosene. …”

    “…Herein, the electrohydrodimerization of 5‐hydroxymethylfurfural (HMF) to the fuel precursor 5,5’‐bis(hydroxymethyl)hydrofuroin (BHH) was investigated on different carbon electrodes. Compared to boron‐doped diamond (BDD) electrodes, on glassy carbon (GC) electrodes a less negative HMF reduction onset potential and a switch in product selectivity from BHH to the electrocatalytic hydrogenation product 2,5‐di(hydroxymethyl)furan (DHMF) with increasing overpotential was found. …”
