One micron is a thousandth of a millimeter, which equals about the diameter of a pinhead. Therefore, even if we enlarged the rounded bacterium a thousand times, it would only be the size of a pinhead. We barely see bacteria by a magnification an ordinary microscope of 100 times, even if...
(1/9/1, v/v/v) at 120 °C for three days with a feeding ratio ofI,II, and AgBF4equals to 3:1:1. After copiously washing with dimethyl sulfoxide (DMSO) and tetrahydrofuran (THF), and drying at 120 °C for 8 h, mCOF-Ag was obtained as a light yellow solid (74% ...
Generally speaking, public-key cryptographic systems consist of raising elements of some group such as GF(2n), Z/NZ or elliptic curves, to large powers and reducing the result modulo some given element. Such operation is often called mod... N Nedjah,LDM Mourelle 被引量: 229发表: 1990年 ...
2. Generally, there are two strategies can be utilized for SLAR films to get high optical transmittances: (1) to fabricate a SLAR film with an optical thickness equal to 1/4 wavelength; (2) to prepare
Futures for November priced in 100% expectations for a 75 basis rate hike in November, but futures also showed some traders were looking for a slightly higher 100 basis points hike. (A basis point equals 0.01 of a percentage point)

The term 'pore' could be geometrically defined for solid foams in different ways (see below), however, in this analysis, it refers to the void space, which is embraced by the cell walls or the cell windows (if eyelets exist). In this context, the pore size can be estimated as the ...
