Light‐Driven Enzymatic Decarboxylation of Dicarboxylic Acids
Photodecarboxylase from Chlorella variabillis (CvFAP) is one of the three known light‐activated enzymes that catalyzes the decarboxylation of fatty acids into the corresponding C1‐shortened alkanes.

Note on the Hyper-Wiener Index [PDF]
The hyper-Wiener index WW of a chemical tree T is defined as the sum of the products n1n2, over all pairs u, u of vertices of T, where n1 and n2 are the number of vertices of T, lying on the two sides of the path which connects u and u.

Wiener-type indices and internal molecular energy [PDF]
In earlier studies it was established that internal molecular energies (Eint) of alkanes can be reproduced, in an approximate yet reliable manner, by means of a molecular-graph-based structure-descriptor U.

Estimation of Formation Enthalpy for Alkanes from 13C NMR Chemical Shifts
The quantitative relationship between the 13C NMR chemical shifts of alkanes and their formation enthalpy was studied. A new approach for calculating the formation enthalpy from the 13C NMR chemical shifts was proposed.

Computing Entropy for Long-Chain Alkanes Using Linear Regression: Application to Hydroisomerization
Entropies for alkane isomers longer than C10 are computed using our recently developed linear regression model for thermochemical properties which is based on second-order group contributions.
