Synthesis of novel disulfide-bridged dilactam crown ethers
The novel macrocyclic dilactams with redox-switched disulfide linkage were synthesized. These compounds were obtained from 2,2′-dithiodibenzoyl chloride in the macrocyclization step by fast addition method in moderate yields.
Electronically Switchable Microwave Bandpass Filter With Wide Stopband Using Parallel Loaded Stepped-Impedance Resonators
In this paper, a new switchable bandpass filters based on loaded stepped-impedance resonators (SIRs) and PIN diode switch is introduced. The diode is used to switch the resonant frequency of stepped-impedance resonators between ON and OFF state...
Design Investigation of a Dual-Mode Switchable Microstrip Bandpass Filter
In this paper, a dual-mode switchable bandpass filter based on open loop resonators and PIN diode switches is designed and implemented. The proposed filter has two center frequency states, one at 1.9 GHz and second one at 2.45 GHz with both...
Super-non-wettable surfaces: A review
The liquid repellency is one of the crucial surface properties which plays important roles in many practical
applications but the researches related to this field are in their infancy. This article reviews the ...
On/off-switchable electrochemical folic acid sensor based onmolecularly imprinted polymer electrode
,N'-methylenebisacrylamide) cross-linker along with o-phenylenediamine was electropolymerised on a gold electrode in the presence of folic acid (FA) as template to produce an on/off-switchable molecularly imprinted polymer (MIP) affinity sensor for folic acid. Differential pulse...
