Ammonia as a Carbon-Free Energy Carrier: NH₃ Cracking to H₂

C-H bonds in Carbon Nanotubes as an Energy Carrier

The main goal of this work was to study the hydrogen interactions with carbon nanostructures (graphene grown on Pt(111), and carbon nanotube (CNT)/Pt composites) in lieu towards finding answers related to two bigger questions – (a) hydrogen storage possibility in carbon nanostructures and (b) band gap opening in graphene (for device applications). X-ray spectroscopy was used as the main experim...

Pathways to hydrogen as an energy carrier.

When hydrogen is used as an alternative energy carrier, it is very important to understand the pathway from the primary energy source to the final use of the carrier. This involves, for example, the understanding of greenhouse gas emissions associated with the production of hydrogen and throughout the lifecycle of a given utilization pathway as well as various energy or exergy efficiencies and ...

Mesoporous Carbon Nanospheres as a Multifunctional Carrier for Cancer Theranostics

Optical nanomaterials with intense absorption in near-infrared (NIR) region hold great promise for biomedical applications such as photothermal therapy (PTT) and photoacoustic imaging (PAI). In this work, we report mesoporous carbon nanospheres (Meso-CNs) with broadband and intense absorption in the UV-Vis-NIR region (300-1400 nm) and explore their potential as a multifunctional platform for ph...

Free Energy as a Geometric Invariant

The free energy plays a fundamental role in statistical and condensed matter physics. A related notion of free energy plays an important role in the study of hyperbolic dynamical systems. In this paper we introduce and study a natural notion of free energy for surfaces with variable negative curvature. This geometric free energy encodes a new type of marked length spectrum of closed geodesics, ...
