TL;DR: Techniques for the determination of nitrite and/or nitrate developed during the past 15 years have become more attractive due to its facility availability, high sensitivity and selectivity, low limits of detection and low-cost.

TL;DR: A strategy for enforcing the nanotubular assembly of rigid macrocycles in both the solid state and solution based on the interplay of multiple hydrogen-bonding and aromatic π-π stacking interactions is reported, establishing a solid foundation for developing synthetically accessible, robust nanostructured systems with broad applications.

TL;DR: Further chemical investigation of the Chinese medicinal fungus Phellinus igniarius has resulted in the isolation and structural elucidation of three pyrano[4,3-c]isochromen-4-one derivatives, phelligridins H, I, and J, together with the known compounds davallialactone and scopolin.

TL;DR: Seven new sesquiterpenes (1-7), together with seven known sesQUiterpened compounds, together with eight known sESquiter penes, have been isolated from the red alga Laurencia tristicha.

TL;DR: Six newphenanthrene derivatives, including three monophenanthrenes (1-3), two biphenanholdes (4 and 5), and a triphenanthrene (6), have been isolated from an ethanolic extract of the tubers of Cremastra appendiculata.
