Closed Locally Minimal Networks on the Surfaces of Convex Polyhedra

open access: yesМоделирование и анализ информационных систем, 2013
Closed locally minimal networks can be viewed as “branching” closed geodesics. We study such networks on the surfaces of convex polyhedra and discuss the problem of describing the set of all convex polyhedra that have such networks.

Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics

open access: yesAdvanced Materials, EarlyView.
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent

Designing the Self‐Assembly of Disordered Materials Via Color Frustration

open access: yesAdvanced Materials, EarlyView.
What if disorder can be designed? This work introduces a strategy to self‐assemble amorphous materials by designing bonding rules for patchy particles that suppress crystallinity and promote frustration. The designer particles nucleate a network of dodecahedral cages from the liquid, yielding a novel equilibrium amorphous phase. This approach redefines
