Gold nanoparticles electrodeposited on glassy carbon using cyclic voltammetry: Application to Hg(II) trace analysis [PDF]

open access: yes, 2012
The electrochemical determination of Hg(II) at trace level using gold nanoparticles–modified glassy carbon (AuNPs–GC) electrodes is described. Starting from HAuCl4 in NaNO3, gold nanoparticles (AuNPs) were deposited onto Glassy Carbon (GC) electrodes ...

RAB39B Related Parkinsonism in an Italian Family: A Unique Use of Advanced Therapies

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Parkinson's disease (PD) is a neurodegenerative disorder that may sometimes be caused by deleterious genetic variants. Among them, RAB39B polymorphisms are known as rare causes of early‐onset PD associated with intellectual disability (Waisman's syndrome).

Cobalt improves nickel hydroxide electrodes for batteries [PDF]

open access: yes, 1969
Positive nickel hydroxide electrodes containing 20 mole percent of cobalt hydroxide are more efficient than when impregnated to the same degree by weight with nickel hydroxide alone. Charge-acceptance and oxygen-evolution tests indicate cobalt electrodes

Nanometer-spaced platinum electrodes with calibrated separation

open access: yes, 2002
We have fabricated pairs of platinum electrodes with separation between 20 and 3.5 nm. Our technique combines electron beam lithography and chemical electrodeposition. We show that the measurement of the conductance between the two electrodes through the

Hydrogel‐Based Capacitive Sensor Model for Ammonium Monitoring in Aquaculture

open access: yesAdvanced Engineering Materials, EarlyView.
Traditional techniques for monitoring aquaculture water quality, particularly ammonium levels, harm fish. This work presents a novel capacitive sensor with an ionic hydrogel transducer to monitor ammonium concentration in real time based on the ammonium‐induced hydrogel dissociation and osmotic pressure. Monitoring aquaculture water quality, especially

Fabrication of a low-cost strap for holding precordial electrodes on the hirsute chest

open access: yesJournal of Family Medicine and Primary Care, 2020
Background: Reusable suction-cup electrodes are used for recording a 12-lead electrocardiogram (ECG) in resource-limited settings. These electrodes may easily detach if those are attached on a hirsute chest.
