An effective, general and reliable surface-charge engineering method is developed for high-performance triboelectric nanogenerators that are based on a pair of identical materials.
The fundamental properties of a pair of electrode materials is related to the size of a battery required for a particular application and the fraction of the capacity in the battery that can be accessed during a given driving cycle is discussed.
To represent a general M-material configuration, M(M−1)/2 level set functions need to be accounted for; problems of practical interest use far fewer functions, as not all pairs of materials share an interface, and level-set functions that coincide are grouped together.
A pair of jeans containing material that blocks wireless signals is being developed in conjunction with anti-virus firm Norton.
A 4.1-kb fragment of genomic DNA from a wild-type plant (Col-0), encompassing the 2.3-kb upstream sequence of BOB1 and the 1.8-kb coding region of BOB1, was amplified by PCR with a pair of primers (supplementary material Table S2).
Painted on a pair of Japanese doors with materials like glitter, gold leaf and mica, a large, subtly colored, free-form circle, its edges trailing leaves and blossoms, its center a nest of them, sits on a background of broad vertical stripes that glow in the tones of Asian antiquities.
Therefore, careful selection of a pair of polymer and inorganic material is very important.
Two-photon absorption is a third order optical process describing the quasi simultaneous absorption of a pair of photons in a material, with a quadratic dependence relatively to light intensity.
The contact resistance is affected by the contacting of the pair of materials, which will cause a voltage drop across the contact surfaces.
Next, we calculated the minimum number of recombination events (rmin) for every gene (supplementary table S2, Supplementary Material online) using the four-gamete test, a simple method locating a pair of segregating sites with four haplotypes (Materials and Methods).
