Numbers of companies are using AMS (Accounting Management System) to manage their accounting data. In the case of large corporations they tend to use ERP (Enterprise Resources Planning), but except them most of companies use AMS to manage their accounting information. In the other words, every company is using some sort of digital data format to manage… (More)
Palaeontological data of extinct groups often sheds light on the evolutionary sequences leading to extant groups, but has failed to resolve the basal metazoan phylogeny including the origin of the Cnidaria. Here we report the occurrence of a stem-group cnidarian, Cambroctoconus orientalis gen. et sp. nov., from the mid-Cambrian of China, which is a colonial… (More)
We introduce a simple process to synthesize few-layered MoS(2) nanosheets supported on coaxial carbon nanotubes through an L-cysteine-assisted hydrothermal route, in which L-cysteine, a cheap and ordinary amino acid, plays a fundamental role in controlling the morphology of the hybrid material and the binder to help the growth of MoS(2) nanosheets on the… (More)
This paper investigates the importance of substituent placement when designing low-molecular mass π-organogelators. The electron-deficient NO2 substituent was systematically added to novel T-shaped phenazines to examine electronic as well as assembly properties. This T-shaped molecular platform promotes selective electronic tuning, which can be… (More)
This paper reports novel pyrazine-acenes containing electron-deficient heteroaromatic π-extenders, such as pyridine, pyrazine, and benzothiadiazole, directly fused with pyrazine. Electronic properties of these systems were characterized by UV-Vis, fluorescence spectroscopy, and cyclic voltammetry. Computational electronic property evaluation of all… (More)
The current study employs both theoretical and experimental methods to characterize the electronic properties associated with peripheral substitution on asymmetric phenazine and bisphenazine systems. Substituent groups include F, Cl, Br, and NO(2) with substitutions made at different positions on the heteroaromatic rings in order to assess the effects of… (More)
This paper reports the formation of an organogel of an asymmetric bisphenazine through the growth of one-dimensional nanofibers via a coopertive interplay of pi-pi interaction, hydrogen bonding, and van der Waals interaction and the colorimetric acid sensing property of the nanofibers.
This paper reports a new layer-by-layer assembly approach to fabricate multilayers of cofacially aligned porphyrins on solid supports by a selective siloxane formation utilizing tetraphenylporphyrinatosilicon(IV) chloride as the building block.
