Chromogenic guest-responsive host compounds which allow rapid guest screening [PDF]

open access: yes, 2002
Azo host compounds undergo rapid and clearly visible colour changes from yellow to bright orange/red on complexation with guest molecules, while no colour change is noted in the absence of complexation.

Manganese-containing mixed oxide electrodes as anode materials for degradation of model organic pollutants [PDF]

open access: yes, 2017
Mixed oxide thin film electrodes have been prepared by thermal decomposition from alcoholic solution on Pt substrate. In particular, three different anodes have been obtained by co-deposition of Ru (Ruthenium) and Mn (Manganese) oxides, Ru, Mn and Cu ...

Recent Advancements in Lung Cancer Metastasis Prevention Based on Nanostrategies

open access: yesAdvanced Science, EarlyView.
Metastasis is the leading cause of death in patients with lung cancer. Nanomedicine can be used to prepare efficient drug delivery systems owing to their advantages and plays an important role in the synergistic antimetastasis of lung cancer. This comprehensive review summarizes the emerging nanostrategies against lung cancer metastasis based on the ...
