Small-pore hydridic frameworks store densely packed hydrogen.

Nanoporous materials have attracted great attention for gas storage, but achieving high volumetric storage capacity remains a challenge. Here, by using neutron powder diffraction, volumetric gas adsorption, inelastic neutron scattering and first-principles calculations, we investigate a magnesium borohydride framework that has small pores and a partially negatively charged non-flat interior for hydrogen and nitrogen uptake. Hydrogen and nitrogen occupy distinctly different adsorption sites in the pores, with very different limiting capacities of 2.

Genetic and serum markers in adult degenerative scoliosis: a literature review.

Study Design: Literature review.

Objective: Adult degenerative scoliosis (ADS) is becoming a more prevalent diagnosis with an increasing elderly population. Our objective is to provide a literature review of genetic and serum markers in ADS.

The Financial Impact of the COVID-19 Pandemic on Neurosurgery Practice in Spring 2020.

Background: The coronavirus disease 2019 (COVID-19) pandemic has changed health care delivery across the United States. Few analyses have specifically looked at quantifying the financial impact of the pandemic on practicing neurosurgeons. A survey analysis was performed to address this need.
