A collaboration between the University of Michigan and AFRL has resulted in 3D-printed metamaterials that can block vibrations using complex geometries. Inspired by nature and theoretical physics, these “kagome tubes” demonstrate how geometry can yield properties that chemistry alone cannot achieve. While the innovation could reshape structural design, researchers still face challenges in balancing weight and strength while developing new testing frameworks.

In-brief analysis

October 16, 2025

Data source: U.S. Energy Information Administration, Liquefaction Capacity File, and trade press
Note: Export capacity shown is project’s baseload capacity. Online dates of LNG export projects under construction are estimates based on trade press and do not reflect expectations for projects ramping to full production following initial shipment. LNG=liquefied natural gas; FLNG=floating liquefied natural gas

Liquefied natural gas (LNG) exporters in the United States have announced plans to more than double U.S. liquefaction capacity, adding an estimated 13.9 billion cubic feet per day (Bcf/d) between 2025 and 2029, according to our Liquefaction Capacity File and trade press reports. The United States is already the largest exporter in the world with 15.4 Bcf/d of capacity.

More broadly, LNG export capacity in North America is on track to increase from 11.4 Bcf/d at

AEI

The Spanish Research Agency (AEI) will consider US-Spanish Research Proposals, US-Spanish Data Sharing Proposals, and Multilateral Research Proposals and Multilateral Data Sharing Proposals involving the United States and Germany, submitted to NSF in response to this solicitation. All the information required for Spanish applicants to successfully submit a proposal can be found in the annex to this solicitation available on the AEI webpage at https://www.aei.gob.es/noticias/anuncio-convocatoria-proyectos-multilaterales-estados-unidos-participacion-aei-marco-0. AEI strongly encourages Spanish applicants contact the national point of contact before the proposal is submitted.

In response to this solicitation, an investigator may participate as PI or co-PI in no more than one proposal involving Spain per review cycle. AEI recommends the signature of a consortium agreement covering financial and intellectual property issues as well as the management and delivery of project activities to all partners involved in bilateral or multilateral projects.
