The injection of pure spin current into the non-magnetic layer plays a crucial role in transmitting, processing, and storing data information realm spintronics. To understand broadband molecular spintronics, pyrene oligomer film (≈20 nm thickness) was prepared using an electrochemical method forming indium tin oxide (ITO) electrode/pyrene covalent interfaces. Permalloy (Ni80 Fe20 ) films with different nanoscale thicknesses were used as top contact over ITO/pyrene layers to estimate pumping efficiency across interfaces ferromagnetic resonance spectra. spintronic devices are composed permalloy/pyrene/ITO orthogonal configuration, showing remarkable from permalloy film. large is evident linewidth broadening 5.4 mT at 9 GHz, which direct proof angular momentum transfer interface. A striking observation made high spin-mixing conductance ≈1.02×1018 m-2 , value comparable conventional heavy metals. Large moment observed permalloy-pyrene interfaces, especially lower thickness permalloy, indicating strong spinterface effect. Pure electrochemically grown ensures efficient transport, opens new area

Abstract The present era has seen tremendous demands for low‐cost electrochromic materials visible‐region multicolor display technology, paper‐based, flexible, and wearable electronic devices, smart windows, optoelectronic applications. Towards this goal, the authors report large‐scale, high‐yield robust polyelectrochromic devices fabricated on rigid to flexible ITO substrates comprising novel anthracene containing viologen, (1,1″‐bis(anthracen‐9‐ylmethyl)‐[4,4″‐bipyridine]‐1,1'‐diium bromide, abbreviated as AnV 2+ ), polythiophene (P3HT). Interestingly, show three states of reversible visible color in response applied bias, sub‐second second switching time (0.7 s/1.6 s), high coloration efficiency (484 cm 2 /C), longer cycling stability up 9,000 s (3,000 cycles). Introduction moieties viologen inhibits formation an undesired dimer cation radicals otherwise device's color‐switching would be hampered when bias polarity is reversed. are tested with commercially available cells perform—a unique approach toward practical computational study facilitates understanding experimental results. Alternating current (AC)‐based electrical impedance spectroscopy reveals that P3HT enhanced charge transfer . This work shows CMOS compatibility can pave way developing cost‐effective devices.

Organic materials are promising candidates for thermoelectric cooling and energy harvesting at room temperature. However, their electrical conductance (G) Seebeck coefficient (S) need to be improved make them technologically competitive. Therefore, radically new strategies developed tune properties. Here, we demonstrate that G S can tuned mechanically in paramagnetic metallocenes, properties significantly enhanced by the application of mechanical forces. With a 2% junction compression, full figure merit is more than 200 times. We this because spin transport resonances metallocenes strongly sensitive interaction between organic ligands metal center, which not case diamagnetic analogue. These results open avenue development future quantum computers generating electricity from low-grade sources.

β-Secretase, the β-site amyloid precursor protein (APP) cleaving enzyme 1 (BACE1), is a key hydrolytic in pathway of β-amyloid (Aβ) production brain patient with Alzheimer's disease (AD). BACE1 considered promising biomarker for early detection AD. A ferrocene probe (Fc-Probe) synthesized, where aldehyde group on can specifically recognize N terminus APP peptide fragment. The sensor's design involves gold nanoparticles (AuNPs) glassy carbon electrode (GCE) surface, which allows binding When cleaves acetylated peptide, exposed and triggers an electrochemical signal from Fc-Probe. developed sensor detect range 0.02 to 50 U/mL, limit 8.0 mU/mL. Such provides simple, sensitive, low-cost methodology, enabling "signal-on" activity.
