Open carbon frameworks - a search for optimal geometry for hydrogen storage
Published 2013“…From an analysis of an analytical model and simulations of adsorption the physical limits of hydrogen adsorption have been defined: (i) higher storage capacities in slit-shaped pores can be obtained by fragmentation/truncation of graphene sheets into nano-metric elements which creates surface areas in excess of 2600 m2/g, the surface area for infinite graphene sheets; (ii) the positive influence of increasing surface area is compensated by the decreasing energy of adsorption in the carbon scaffolds of nano-metric sizes; (iii) for open carbon frameworks (OCF) built from coronene and benzene molecules with surface areas 6500 m2 g-1, we find an impressive excess adsorption of 75–110 g H2/kg C at 77 K, and high storage capacity of 110–150 g H2/kg C at 77 K and 100 bar; (iv) the new OCF, if synthesized and optimized, could lead to required hydrogen storage capacity for mobile applications.…”

Engineering the Surface and Mechanical Properties of Water Desalination Membranes Using Ultralong Carbon Nanotubes
Published 2018“…More pronounced effect on membrane’s mechanical properties was observed due to compatibility of CNTs with PS matrix when compared to other factors (i.e., changes in the CNT aspect ratio). The water contact angle for PS membranes incorporated with commercial CNT sharply decreased from 73° to 53° (membrane hydrophilization) for membranes with 0.1 and 1.0 wt. % of CNTs, while for the same loading of produced CNTs the water contact angles for the membrane samples increased from 66° to 72°. …”

A BRET-based Mpro biosensor containing a nanobody and tandem cleavage sites shows an increased cleavage rate
Published 2025“…Gaussian accelerated molecular dynamics (GaMD) simulations of the predicted alpha-helical synthetic Mpro cleavage sequences revealed a dynamic nature of the cleavage sequences, which is critical for their efficient cleavage, and a relatively short end-to-end distances, which is required for high BRET. Live cell assays revealed a cleavage sequence length-dependent resonance energy transfer, except for the 12× -syn cleavage site, and an increased rate of cleavage and a decreased pharmacological inhibitor efficacy for the Mpro biosensor containing 2× cleavage sequences. …”
