A collaborative effort by the research groups of Professor Haruhiko Fuwa from Chuo University and Professor Masashi Tsuda from Kochi University has culminated in the structure elucidation and total ...

Abstract: A high-performance ultrawideband terahertz absorber is proposed. Constituted by silicon hemi-ellipsoid and monolayer graphene that is separated by a dielectric spacer from a bottom metal ...

Abstract: A frequency-region selective light absorber is theoretically investigated by an electro-optical waveguide cavity coupled plasmonic micro-structure. A spectrally separated broadband ...

The refractive index sensitivity of plasmonic fields has been exploited for over 20 years in analytical technologies. While this sensitivity can be used to achieve attomole detection levels, they are ...

The alternative text for this image may have been generated using AI. The IR spectrum of 2 was recorded to fulfill the new compounds (Figure 3). However, due to the multifunctional character of the ...

Chalcones (1) are intermediary compounds of the biosynthetic pathway of a very large and widespread group of plant constituents known collectively as flavonoids [2] . Among the naturally occurring ...

Complexity and the presence of stereogenic centers have been correlated with success as compounds transition from discovery through the clinic. Here we describe the synthesis of a library of ...

Careful examination of the published NMR data for isoepitaondiol, a meroditerpenoid from Stypopodium flabelliforme, suggests that its published structure 1 must be revised. On the basis of extensive ...

Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. These metrics are regularly updated to ...

A most potent alpha-glucosidase inhibitor named salacinol has been isolated from an antidiabetic Ayurvedic traditional medicine, Salacia reticulata WIGHT, through bioassay-guided separation. The ...
