GLUE Opportunity Description

Overview: DARPA/DSO has issued an ARC Opportunity, inviting submissions of Abstracts for innovative exploratory research concepts in the technical domain of Materials Science and Engineering. This ARC Opportunity, titled GLUE is issued under the master ARC Exploration Announcement (EA), DARPA-EA-23-01.

Background: The defense, research, and commercial sectors are deploying an increasing amount of human-developed technology underwater. When these technologies need repair or modification, bringing them to the surface is often prohibitively costly and/or infeasible. Improving the ability to service these items in the water column could dramatically increase the array of deployable technologies and how they are employed. Adhesive repair can often be performed faster and with less environmental disturbance than techniques such as welding and mechanical fastening. One key tool is lacking: underwater adhesives. Current adhesives for these applications cannot cure underwater because the interfacial liquid layer prevents the necessary contact between adhesive and substrate. Overcoming this challenge requires an understanding of the mechanisms that govern interfacial liquid evacuation at the microscale and nanoscale levels. Specifically, this necessitates applications of physicochemical principles that leverage the complex phenomena that take place at these interfaces. While advances in computation have enabled tremendous strides in fluid dynamics, little work has been done to model how interfacial liquid is expelled as surfaces come into contact within an aqueous medium.

Special Notice

Event Participation

Registration

There is no registration fee for the webinar. The registration deadline is Wednesday, October 25, 2023 at 12:00 PM Eastern or when attendance capacity is met, whichever comes first. There will be no same-day registration. Advance registration is required for all events and is mandatory for every individual intending to view the webcast either alone or as part of a group. Individuals who are unable to register because the deadline has passed or capacity has been reached (350 participants) for the webinar, will be added to a waitlist. If slots remain open after registration closes or become available due to cancellations, the slots may be filled on a first come, first served basis from the waitlist.

Eligibility

Registration is open to individuals who are U.S. citizens, U.S. permanent residents, and foreign nationals.

All registrants who are not U.S. Citizens must complete and submit either a DARPA Form 60 (U.S. Permanent Resident and Foreign National Visit Request – e.g., industry or academia) or an Official Visit Request (foreign government personnel, only) through the Embassy based in Washington, DC, no later than Monday, October 23 at 5:00 PM Eastern. Failure to submit before this date may result in registration cancellation to allow for waitlist participants to register. Form 60 submission instructions will be provided in the registration confirmation email. Contact your Embassy staff for assistance in submitting the Official Visit Request.
