Similar to biological muscles, the actuator materials can function as artificial muscles by directly converting an external stimulus in form of electrical or chemical energy into a mechanical response through reversible changes material dimensions. As new type high surface-area materials, nanoporous metals represent novel class smart electrodes that undergo dimensional when applying electronic ...

We introduce Electro Pen Nanolithography (EPN), a nanoscale chemical patterning technique. In a single sweep of an ink-coated, biased conducting Atomic Force Microscope (AFM) probe-tip, an underlying thin organic film is oxidized, and the ink molecules are transferred directly to the oxidized regions. Results using trialkoxysilane inks with functional terminal groups are presented, where the sa...

We present here biophysical models to gain deeper insights into how an acoustic stimulus might influence or modulate neuronal activity. There is clear evidence that neural activity is not only associated with electrical and chemical changes but that an electro-mechanical coupling is also involved. Currently, there is no theory that unifies the electrical, chemical, and mechanical aspects of neu...

This paper presents an analysis of the use of red phosphorus as a flame retardant material in encapsulated microcircuits and discusses the reliability risks. Chemical reactions, which can arise when red phosphorus is exposed to ambient humidity to form highly mobile ions and oxygen-containing phosphorus acids, are presented. These ions and acids can induce electro-chemical migration, causing sh...

Stimulated Raman scattering (SRS) microscopy allows label-free chemical imaging based on vibrational spectroscopy. Narrowband excitation with picosecond lasers creates the highest signal levels and enables imaging speeds up to video-rate, but it sacrifices chemical specificity in samples with overlapping bands compared to broadband (multiplex) excitation. We develop a rapidly tunable picosecond...

CONCLUSION This study on eye motility demonstrates a new application of electro-oculography which proved to have a high potential for establishing and diagnosing the cause of diplopia in orbital floor fractures. Electro-oculography is objective and easy to perform even when the restricted eye is covered. The 'uninjured' eye can be used as the reference. Any motility difference between the left ...

Triarylamines are demonstrated as novel, tunable electroactivated photocatalysts that use dispersion precomplexation to harness the full potential of visible photon (>4.0 V vs. SCE) in anti-Kasha photo(electro)chemical super-oxidations arenes.

Abstract A short discussion is given of the convenience integrating electrochemistry and chemometrics in university degrees related to chemistry, some selected examples are presented illustrate possibilities combining both disciplines for solving (electro)chemical problems different nature.

several laundry houses throughout tehran consume a large amount of water each day and discharge the resulting wastewater into septic tanks or municipal sewage system without any suitable pretreatment. this would result in severe contamination and other serious environmental issues. in the present study, performance of electrocoagulation/flotation process with aluminum and iron electrodes is com...

this paper is a preliminary communication of a study on removal and recovery of heavy metalsfrom industrial waste waters using electro-coagulation (ec) technique. the larger study envisages use of solarenergy for producing the d.c. current, and simple chemical methods of standard methods in chemistry like useof hydrochloric acid, hydrogen sulfide, collection of precipitate, incineration and get...
