The kinetics of charge transfer complex (CTC) of 2, 3, 5, 6-tetramethoxyl-l, 4-benzoquinone (TMOQ) with two alicyclic N-donors, piperidine (PD) and morpholine (ML), in methanol, has been investigated by ultraviolet visible spectroscopy. The transformation leads to the formation of substitution produ...

A series of laterally o-difluoro-substituted chiral liquid crystals, S(+)-2-methyl-1-butyl 4'-[(4-alkoxyl-2, 3-difluoro)benzoyloxy]-4-biphenyl carboxylates, have been synthesized using a simple process. Their molecular structures were determined using IR, NMR, MS, and EA. Their transition tem...

Sentiment classification is an automatic opinion classification method to classify the product reviews on web into positive or negative opinions to help consumers or sellers to understand the opinions and evaluations from existing customers. Semantic-oriented approach is one of the recent developmen...

An information extraction-based technique is proposed for RTL-to-gate equivalence checking. Distances are calculated on directed acyclic graph (AIG). Multiplier and multiplicand are distinguished on multiplications with different coding methods, with which the operand ordering/grouping information c...

Two new spectroscopic methods to detect the optical activity of liquid-liquid interfaces have been developed. The first one is the centrifugal liquid membrane (ClM) method combined with a conventional circular dichroism (CD) spectropolarimetry and the second one is a more interfacial specific second...
