Hybrid spin Hall nano-oscillators based on ferromagnetic metal/ferrimagnetic insulator heterostructures
Our heterostructures are composed of two different lithium aluminum ferrite compositions (Li0.5Al1.0Fe1.5O4 (LAFO) or Li0.5Al0.5Fe2O4 (LFO)) (x nm)/Py(5 nm)/Pt(5 nm) layers with varied LAFO or LFO thickness x (including x = 0, i.e., just Py/Pt layers). The Py/Pt layers are patterned into 400 nm wide nanowires with a 400 nm gap between two Au contact pads, as shown in Fig. 1a. Detailed…

Biomolecular and quantum algorithms for the dominating set problem in arbitrary networks
In this section, we describe, step by step, our biomolecular algorithm for the dominating set problem. After each step we show how the corresponding part can be implemented using quantum circuits. Generating dominating set candidate space In the first step of the algorithm, the dominating set candidate space is created which consists of \(2^n\) candidate…

AlphaFlow: autonomous discovery and optimization of multi-step chemistry using a self-driven fluidic lab guided by reinforcement learning
SDL hardware: modular fluidic micro-processors The developed SDL, shown in Fig. 2a, operates from a starting position of no prior information on the reaction sequence, then rapidly generates data on a multi-step process by leveraging RL and a high-efficiency microdroplet flow reactor. Microscale flow reactors encompass a growing class of reaction systems that leverage the high…

Influence of the emulsifier on nanostructure and clinical application of liquid crystalline emulsions
Camellia oleifera seed oil characterization This study aimed to observe the liquid crystal characteristics of different formulations prepared with different surfactants from the molecular level to clinical applications. The o/w emulsions were formulated with Camellia oleifera seed oil as the main ingredient in the oil phase (10% w/w). Before use, the camellia seed oil was…
