This issue of the HDIAC Journal provides readers insight on four of HDIAC’s eight focus areas, with multiple articles in Homeland Defense and Security (HDS) and Medical. First, the Alternative Energy article discusses applications of algal biofuel for defense purposes. Next, the Critical Infrastructure Protection article looks at energy resilience in the wake of three significant hurricanes that struck the United States in 2017. The first HDS article focuses on applications of 3-D printed active composite materials. The second HDS article discusses assault ladders and composite structures used to improve them. The first Medical article centers on aerosol-based drug delivery. Finally, the second Medical article discusses exoskeletons for military use.

Reimagining the Warfighter Exoskeleton

There are many ways to design a powered exoskeleton that assists the warfighter. Design types range from systems focused on increasing physical strength and preventing injury to the wearer (e.g., University of California, Berkeley’s Human…

Assault Ladders & the Open-Architecture Composite Structures Used to Improve Them

Introduction In the early morning of April 7, 1776, after fighting through the night, Capt. John Barry and his crew threw ladders over the deck of the HMS Edward and took command—the first capture of…

Combat Casualty Care: Aerosol-Based Drug Delivery to the Brain

Background Aerosols are fine particles suspended in a gaseous medium [1,2], and aerosol technology could be used for synthesizing novel nanomaterials with independently controlled properties, tuned specifically for a given biological application. Using engineered nanoparticles…

Liquid Fuels Supply: Rethinking Energy Resilience in the Wake of Hurricanes Harvey, Irma, and Maria

Introduction Although Houston is commonly known as “The Bayou City,” some would prefer it to be known as “The Energy Capital of the World.” Of only moderate size when oil was first discovered in Texas…

Algal Biofuel Industry Resilience in a Low-Priced Crude Oil Environment

Introduction The Department of Defense (DoD) has established ambitious goals for its use of renewable fuels for decades to come, and several national-level initiatives have emerged toaid this transition. In 2010, the U.S. Navy’s Great…

4-D Printing: Potential Applications of 3-D Printed Active Composite Materials

Introduction With the advent of 3-D printing, structurally complex objects that were once unbuildable can now be easily manufactured. However, what if these objects could be designed and manufactured to respond or change in predictable…
