The purpose of this study was to determine the effectiveness electrocoagulation method in reducing turbidity, color concentration and COD levels on Jumputan wastewater treatment. electrodes used are aluminum plates as anode cathode. variations research were speed agitation system (batch intermittent system). fixed variable is a voltage 3.5 volts, 2 aluminium electrodes, 250 ml volume wastewater...

Cells regulate their behavior in response to mechanical strains. Cell cultures to study mechanotransuction are typically cm2 in area, far too large to monitor single cell response. We have developed an array of dielectric elastomer microactuators as a tool to study mechanotransduction of individual cells. The array consists of 72 100 μm × 200 μm electroactive polymer actuators which expand unia...

Multivalent-ion batteries are emerging as low-cost, high energy density, and safe alternatives to Li-ion batteries but are challenged by slow cation diffusion in electrode materials due to the high polarization strength of Mg- and Al-ions. In contrast, Ca-ion has a low polarization strength similar to that of Li-ion, therefore a Ca-ion battery will share the advantages while avoiding the kineti...

The advanced battery system is critically important for a wide range of applications, from portable electronics to electric vehicles. Lithium ion batteries (LIBs) are presently the best performing ones, but they cannot meet requirements for more demanding applications due to limitations in capacity, charging rate, and cyclability. One leading cause of those limitations is the lithiation-induced...

Aluminum(III) porphyrins are examined as potential fluoride selective ionophores in polymeric membrane type ionselective electrodes. Membranes formulated with Al(III) tetraphenyl (TPP) or octaethyl (OEP) porphyrins are shown to exhibit enhanced potentiometric selectivity for fluoride over more lipophilic anions, including perchlorate and thiocyanate. However, such membrane electrodes display un...

he inherent lightness and good strength-to-weight ratio of T magnesium has focused attention on increasing applications in aerospace and allied fields. Its density is two thirds that of aluminum-a conventional structure material for aerospace. Magnesium has one drawback: It is prone to atmospheric corrosion. Further, because of its high chemical affinity for aqueous solutions, it is categorized...

The high interest in organic light-emitting device (OLED) technology is largely due to their flexibility. Up to now, indium tin oxide (ITO) films have been widely used as transparent conductive electrodes (TCE) in organic opto-electronic devices. However, ITO films, typically deposited on glass are brittle and they make it difficult to produce flexible devices, restricting their use for flexibl...

The detection of DNA by electrical based methods still faces the challenge of the low amounts of genetic material to be analyzed in order to make the assay useful for biological applications. In this work we present the possibility of detecting DNA strands by measuring a change of capacitance between interdigitated electrodes, of 1, 2 and 3 m widths and spacing, made of aluminum fingers, coated...

The electrochemical behavior of lithium bis~trifluoromethanesulfonyl!imide in ethyl methyl sulfone was studied. The coulombic efficiencies for the oxidation-reduction of lithium at platinum, aluminum, and mercury electrodes were 50, 93, and 99%, respectively. A comparison of the results with Pt, Al, and Hg electrodes suggests that chemical reactions of lithium with the electrolyte contribute to...

We investigate the effect of interfacial buffer layers—vanadium oxide V2O5 and cesium carbonate Cs2CO3 —on the performance of polymer solar cells based on regioregular poly3-hexylthiophene and 6,6 -phenyl C60 butyric acid methyl ester blend. The polarity of solar cells can be controlled by the relative positions of these two interfacial layers. Efficient inverted polymer solar cells were fabric...
