Tubular carbon molecular sieve (CMS) membranes have been recognized as a potential module for commercial application due to its high mechanical strength and large surface area. However, the carbon layer uniformity was restricted by substrate texture and dope fluidity when the dip‐coating method was used. This study evaluated the influence of various parameters of dip‐coating with an integrated vacuum‐assisted...
A low dropout regulator with super-source follower is exhibited and a single-transistor-control low dropout based the flipped voltage follower is discussed in this paper. The buffered flipped voltage follower with super-source follower is proposed to lower its output impedance so that the impedance at the gate of the pass device can be reduced and the pole at the gate is pushed to higher frequency...
The nano-sized TiO 2 powder and immobilized TiO 2 /SBA-15 photocatalysts were synthesized via a polyol method with an attempt to increase the quantitative effect by reducing the particle size and avoid the aggregation by immobilizing on hydrophilic SBA-15 support. The effect of reduction temperature on the TiO 2 crystalline size was investigated. The X-ray diffraction (XRD)...
