Battery-less Long-Range LTE-M Water Leak Detector
Roshan Nepal, Brandon Brown, Shishangbo Yu +3
This work presents a self powered water leak sensor that eliminates both batteries and local gateways. The design integrates a dual compartment electrochemical harvester, a low inp…
Battery-Free and Gateway-Free Cellular IoT Water Leak Detection System
Roshan Nepal, Brandon Brown, Shishangbo Yu +3
This paper presents a battery-free and gateway-free water leak detection system capable of direct communication over LTE-M (Cat-M1). The system operates solely on energy harvested…
Towards Long-Range, Battery-less Water Leak Detection: A LoRa-Based Approach
Roshan Nepal, Roozbeh Abbasi, Brandon Brown +3
This paper presents a battery-less, self-powered water leak detection system that utilizes LoRa communication for long-range, real-time monitoring. The system harvests hydroelectri…
Tuning Structural, Transport and Magnetic Properties of Epitaxial SrRuO3 through Ba-Substitution
Zeeshan Ali, Zhen Wang, Alessandro R. Mazza +5
The perovskite ruthenates (ARuO3, A = Ca, Ba, or Sr) exhibit unique properties owing to a subtle interplay of crystal structure and electronic-spin degrees of freedom. Here, we dem…
Thickness Dependent Itinerant Ferromagnetism in Ultrathin Ba-Doped SrRuO3 films
Zeeshan Ali, Mohammad Saghayezhian, Prahald Siwakoti +2
The electronic and magnetic properties in ABO3 perovskite oxides are extremely sensitive to lattice structure but also the dimensionality, such as the thickness in thin film form.…
Polyhedral distortions and unusual magnetic order in spinel FeMnO
Qiang Zhang, Wei Tian, Roshan K. Nepal +4
Spinel compounds ABX consist of both tetrahedral (AX) and octahedral (BX) environments with the former forming a diamond lattice and the latter a geometrica…
Magnetic Texture in Insulating Single Crystal High Entropy Oxide Spinel Films
Yogesh Sharma, Alessandro R. Mazza, Brianna L. Musico +10
Magnetic insulators are important materials for a range of next generation memory and spintronic applications. Structural constraints in this class of devices generally require a c…
Crystal and Magnetic Structure of Polar Oxide HoCrWO
C. Dhital, D. Pham, T. Lawal +6
Polar magnetic oxide HoCrWO is synthesized and its crystal structure, magnetic structure, and thermodynamic properties are investigated. HoCrWO forms the polar crystal stru…
Fermions and bosons in nonsymmorphic PdSb2 with sixfold degeneracy
Ramakanta Chapai, Yating Jia, W. A. Shelton +6
PdSb2 is a candidate for hosting 6-fold-degenerate exotic fermions (beyond Dirac and Weyl fermions).The nontrivial band crossing protected by the nonsymmorphic symmetry plays a cru…
