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 ...

Unsteady MHD Heat Transfer of a Casson–Williamson Ternary Hybrid Nanofluid Over a Biaxially Stretching/Shrinking Sheet With Cattaneo–Christov Heat Flux and Multi‐Mode Thermal Radiation

Engineering Reports, Volume 8, Issue 7, July 2026.
A numerical study of Casson–Williamson ternary hybrid nanofluid flow reveals that magnetic effects enhance transverse velocity while suppressing axial components, and increased thermal relaxation reduces heat transfer rates under multiple radiation models, highlighting improved control of thermal performance in advanced engineering and electronics ...

Technology Development Outsourcing: When to Join Forces With a Rival?

Journal of Operations Management, Volume 72, Issue 5, Page 676-688, July 2026.
ABSTRACT Knowing the challenges of collaborating with a competitor in developing new technologies, firms sometimes still choose a competitor instead of a noncompeting technology provider. To explore why, this study adopts an inter‐organizational trust view to explain the formation of a technology development outsourcing relationship.

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

Developing Workforce Capability in the Context of HR Ecosystem Learning

Human Resource Management Journal, Volume 36, Issue 3, Page 500-515, July 2026.
ABSTRACT For many organizations, developing workforce capabilities is central as it involves refining critical human resource processes such as upskilling or the acquisition of new profiles. These processes are becoming increasingly complex to manage as organizations collaborate within larger work ecosystems. Surprisingly, little research has addressed
