Why doesn't LaTeX provided ACS style contain article titles

Question

I have tried both:

\usepackage[style=chem-acs]{biblatex}

and

\bibliographystyle{achemso}

and nether one gives titles of articles. However the ACS Style guide clearly specifies that this information should be there. Is this not the style that these packages are trying to provide or am I missing something else?

@article{Akamatsu:2011dz, Abstract = {The
physicochemical properties of candidate compounds play important roles in the 
design of new pesticides. Pesticides must be absorbed by pests, be transported
to the target site, and then interact with proteins. Hydrophobicity is very
important for these processes. Log P, where P is the partition coefficient in
the 1-octanol/water system, is commonly used as a hydrophobic descriptor and 
correlates with membrane permeation and transport. It was recently reported
that permeability by the parallel artificial membrane permeation assay (PAMPA)
could be used to predict human oral absorption of passively transported
compounds. PAMPA, which is a rapid high-throughput screening system, may be
useful to predict pesticide absorption because PAMPA permeability can be
calculated using log P and other parameters. Electronic and structural
properties as well as hydrophobicity are important factors for protein-ligand
interaction. To show the importance of physicochemical properties, the classic
QSAR and CoMFA of neonicotinoids and prediction of bioavailability of
pesticides in terms of membrane permeability in comparison with drugs are 
described.},    Author = {Akamatsu, Miki}, Date-Added = {2012-07-06 13:37:41

Answer 1

This is a package option (from the achemso documentation:)

The articletitle option is a Boolean, and sets whether the title of a paper referenced appears in the bibliography. The default is articletitle=false for the achemso style and articletitle=true for the biochem style.

Similarly in biblatex-chem:

The use of article titles varies between individual journals. The boolean option articletitle is available is control this behaviour. The standard settings for the chem-acs, chem-angew and chem-rsc styles have this option turned off, while the chem-biochem sets this option true.

Answer 2

Try this in first line:

\documentclass[journal=jcisd8,manuscript=article]{achemso}

jcisd8 means journal of chem. info. and modeling.

Replace that with your journal code
