Spectral and Isoperimetric Bounds on Flat Tori
Emanuel Milman
We record several elementary relations between spectral and isoperimetric parameters of a flat torus and the covariance structure of a fundamental do…
Ferroelastic exciton splitting in hybrid perovskite nanowalls
Afreen, J. Delgado-Alvarez, H. Krishna Mishra +9
Hybrid metal-halide perovskites are soft semiconductors in which electronic excitations are strongly influenced by lattice distortions and structural phase transitions. An importan…
Polycrystalline ferroelectric croconic acid for multisource environmental energy harvesting
Gloria P. Moreno-MartÃnez, Hari K. Mishra, Xabier GarcÃa-Casas +5
The development of organic ferroelectric materials through scalable and simplified fabrication routes remains a major challenge for next-generation energy-harvesting technologies.…
Adamantane plasma polymers: fluorine-free vacuum-processable triboelectric thin films for all-triboelectric nanogenerator configurations
Gloria P. Moreno-Martinez, Fernando Nunez-Galvez, Hari Krishna Mishra +12
Triboelectric nanogenerators (TENGs) are major drivers in on-site power generation for smart devices, enable self-powered sensors, and introduce novel catalytic processes. Here, we…
Remote Plasma Polymers of Iron (II) Phthalocyanine in Polyacrylonitrile-Derived Carbon Electrospun Fibers as Electrode for Supercapacitors
Jose M. Obrero, Jorge PV Tafoya, Michael Thielke +6
Remote plasma-assisted vapour deposition under nitrogen (RPAVD-N2) is introduced as a single-step, solvent-free, room-temperature strategy to integrate iron(II) phthalocyanine (FeP…
Unlocking the hybrid piezo and pyroelectric nanogenerators performance by SiO2 nanowires confinement in poly(vinylidene fluoride)
Juan Delgado-Alvarez, Hari Krishna Mishra, Francisco J. Aparicio +5
We report on the development of a novel flexible piezo/pyro-electric nanogenerator (PPNG) that combines a uniform film of poly(vinylidene fluoride) (PVDF) infiltrated over vertical…
