Abstract Deep brain stimulation with implanted electrodes has transformed neuroscience studies and treatment of neurological psychiatric conditions. Discovering less invasive alternatives to deep could expand its clinical research applications. Nanomaterial-mediated transduction magnetic fields into electric potentials been explored as a means for remote neuromodulation. Here we synthesize magnetoelectric nanodiscs (MENDs) core–double-shell Fe 3 O 4 –CoFe 2 –BaTiO architecture (250 nm...
This paper demonstrates that air-stable radicals enhance the stability of triboelectric charge on surfaces. While surfaces is often undesirable (e.g., static discharge), improved retention can benefit specific applications such as air filtration. Here, it shown self-assembled monolayers (SAMs) containing radicals, 2,2,6,6-tetramethylpiperidin-1-yl)oxidanyl (TEMPO), hold longer than those without TEMPO. Charging and are monitored by Kelvin Probe Force Microscopy (KPFM) a function time....
Abstract Electroadhesion is an attractive mechanism to electrically modulate adhesion surfaces. arises from the interaction of electric fields with conductive or dielectric materials. devices consist in‐plane, interdigitated electrodes that generate out‐of‐plane fields, which increase target To date, these have predominantly been composed carbonaceous Here, liquid metal utilized create in silicone substrates. Liquid can be patterned a variety unique ways, including microfluidic injection,...
Abstract Liquid metal is a compelling material for making soft and stretchable devices due to its high electrical conductivity extreme stretchability. One way pattern liquid nebulize it into small droplets, spray onto surface as film, then use laser “sinter” circuit patterns. Here, shown that including poly(amic acid) in the spray‐deposited film has multiple benefits: (1) allows unsintered regions be removed easily, (2) lowers power required sintering, (3) converts carbon upon exposure...
Abstract Recording and modulation of neuronal activity enables the study brain function in health disease. While translational neuroscience relies on electrical recording techniques, mechanistic studies rodent models leverage genetic precision optical methods, such as optogenetics fluorescent indicator imaging. In addition to signal transduction, neurons produce receive diverse chemical signals which motivate tools probe modulate neurochemistry. Although past decade has delivered a wealth...
Abstract This paper describes laser exposure to tune the infrared (IR) emissivity of a film eutectic gallium indium (EGaIn) particles. EGaIn – liquid metal at room temperature forms native oxide that keeps particles from spontaneously percolating. Photothermal energy CO 2 percolates into conductive network. Here, it also causes decrease in IR 0.4 0.24 over range 7.5–13 µm wavelength (measured by an camera) with increase fluence 1.4 1.9 J cm −2 . The percolate most prominently bottom film,...
General Atomics-Carbon Hydrogen (GA-CH) and Deuterium (GA-CD) aerogels have applications as inertial confinement fusion (ICF) targets at the National Ignition Facility, Omega Laser Z Pulsed Power Facility. However, experiments these facilities require fabrication of precise geometries aerogels, achievable only by machining. Unfortunately, machining low-density (<50 mg/cm3) GA-CH is difficult, given their fragile structure. Higher-density although easier to machine, are left with a small nub...
