Abstract:
In the version of this Article originally published, multiple changes to the "Results and discussion" section were required. In paragraph 1, "(Supplementary Fig. 1)" should have read "(Fig. 1e-j and Supplementary Fig. 1)"; in the first sentence of paragraph 3, "(R6G)" should have read "(R6G, Fig. 2i)"; in paragraph 6 in the sentence beginning "Temporal release of hydrophilic...", Supplementary Fig. 4 should have been cited after "360 nm"; in paragraph 9, in the sentence beginning "To test this...", "Fig. 4e" should have read "Fig. 4a"; in paragraph 10, in the sentence beginning "When the irradiation...", "(Fig. 4a-d)" should have read "(Fig. 4d,e)"; in paragraph 11, in the sentence beginning "Pristine PLA", "P1" should have read "P2"; and in the penultimate paragraph, in the sentence beginning "Moreover, a control PEG-PLA...", "block copolymer" should have been followed by (P5); Fig. 4g should have been Fig. 4c; "hydrophobic azobenzene small molecules" should have been followed by (12); and Fig. 4f should have been Fig. 4b. Finally, Supplementary Videos 1 and 2 were missing from the Article. All of these corrections have been made to the online versions.

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...

Isomerism in Alkenes
An isomer is called cis-2-butene when the methyl groups are on the same side of the double bond, and the other stereoisomer, in which methyl groups are on the opposite side of the double bond, is called trans-2-butene. The cis and trans stereoisomers are not...
