The Biofuels Blueprint: Understanding the U.S. Renewable Fuel Standard
Applied Economic Perspectives and Policy, Volume 48, Issue 3, Page 565-590, July 2026.ABSTRACT We provide a comprehensive review of the U.S. Renewable Fuel Standard (RFS), synthesizing nearly two decades of program evolution, market outcomes, and economic analysis. The RFS mandates minimum volumes of renewable fuel blending through a nested structure based on life‐cycle greenhouse gas reductions, enforced via tradeable Renewable ...

Mass Spectrometry Structural Proteomics Enabled by Limited Proteolysis and Cross‐Linking
Mass Spectrometry Reviews, Volume 45, Issue 4, Page 644-671, July/August 2026.ABSTRACT The exploration of protein structure and function stands at the forefront of life science and represents an ever‐expanding focus in the development of proteomics. As mass spectrometry (MS) offers readout of protein conformational changes at both the protein and peptide levels, MS‐based structural proteomics is making significant strides in the

Cost analysis of stratospheric albedo modification delivery systems
Environmental Research Letters, 2012 We perform engineering cost analyses of systems capable of delivering 1–5 million metric tonnes (Mt) of albedo modification material to altitudes of 18–30 km. The goal is to compare a range of delivery systems evaluated on a consistent cost basis.
