Structure-mechanics analysis of shark egg cases has revealed that dynamic reorganization of the nanolatticed architecture provides strength and resilience without compromising permeability.

Since the 1980s, it has been assumed that the architecture of the mammary gland is defined by prealigned fibers of collagen, which were posited to serve as a template for the formation of the mammary epithelial tree. Princeton researchers tested the validity of this paradigm.
Ionic transport in polymers typically undergoes a standard liquidlike transport mechanism whereby diffusion of ions is permitted only by relaxation of the local fluid elements, this mechanism results in limitations in designing conductive and cation-selective electrolytes. In this work we demonstrate that superionic transport (untethered to polymer dynamics) is possible in semicrystalline poly(zwitterionic liquids).
Samples of Alnico magnets were printed by selective laser melting, and their microstructure was investigated in 3D at the mm3-scale using the femtosecond-laser enabled TriBeam microscope.
In an experiment related to the theory of Luttinger Liquids (LLs), a team led by Princeton University physicists and chemists reports the realization of a one-dimensional linear array of LLs in a moiré superlattice – a new quantum state in an engineered structure made from a known material.
A computational approach was implemented to design Mn2XY tetragonal inverse Heusler alloys that host magnetic antiskyrmions whose stability are sensitive to elastic strain.
Solid-state polymer electrolytes offer a safer alternative to traditional lithium-ion batteries based on organic electrolytes. However, current benchmark polymer electrolytes lack ion transport selectivity (t+ = 0.2) which limits their commercial use. We demonstrate the enhancement of lithium-ion transport (t+ = 0.48) of PMS-based polymers by taking advantage of the steric and electronic properties of imidazole ligands.
Complex coacervation is a process in which oppositely charged macro-molecules in solution condense into dense liquids. While primarily driven by charge effects or, with DNA, basepairing, other macromolecular traits are likely to have strong effects. This Seed project leverages modern tools of DNA sequence control and biochemistry to study the fundamental physical principles underlying coacervation,
In collaboration with the newly established NSF BioPacific MIP, the MRL X-ray facility team spearheaded the development of an SAXS-WAXS (small and wide angle x-ray scattering) laboratory beamline with unparalleled beam brightness for high throughput characterization of biopolymers and nanostructures.
This research focuses on theoretical prediction of strong coupling between the THz excitations in a topological insulator (TI) and a III-V quantum well, providing a potential material platform for optoelectronic device applications in the THz frequency domain.
