Procedure for the preparation of pyridine compounds that contain sulfur (Machine-translation by Google Translate, not legally binding)Process for the preparation of sulfur-containing pyridine compounds, characterized in that 3-pyridinesulfinic acid or its salts are transposed with a halogeno-substituted ...
Natural gas and oil contain sulfur compounds, both organic and hydrogen sulfide, both of which must be removed before they are used as fuels or chemical feedstock. Veolia Closes USD 325m Acquisition of Sulfur Product Division from Chemours Desulfurizati on of aromatic sulfur compounds much complic...
Autotrophic thiobacilli deploy the Calvin cycle for CO2 fixation and some have cytoplasmic inclusions that contain crystalline Rubisco (Beudeker et al., 1980). Many CSB are not obligate chemolithoautrophs, but are either facultative autotrophs (e.g., T. pantotropha, T.(or Paracoccus) ...
Garlic Chemistry: Chemical and Biological Properties of Sulfur-Containing Compounds Derived from Garlic Garlic (Allium sativum L.) is rich in biologically active organosulfur compounds. Although intact garlic cloves contain a limited number of organosulfur compounds, such as alliin, methiin and gamma-glu...

The gaseous sulfur compounds that are either produced or consumed by microorganisms in coastal sediments and that have an important role in the global sulfur cycle are H2S, dimethyl sulfoxide (DMSO), dimethyl sulfide (DMS), methane thiol (MeSH), carbonyl sulfide (OCS), carbon disulfide (CS2),...
The invention includes polymers that contain a heterocyclic ring, preferably an oxygen- or sulfur-containing ring. The heterocyclic ring is preferably fused to the polymer backbone. The invention also provides photoresists that contain s... GG Barclay,Y Wang - WO 被引量: 109发表: 2001年 Synthes...
aromatic VOCs were the most common feature and non-conjugated cyclic compounds were the second most common structural feature. The third most frequently observed are ketones. VOCs that contain an ether or ester functional group are the least observed. The potential biomarkers for metastasized breast ...
The most typical S 2- complexes contain M 3 S units which have characteristic electron reservoir properties. These properties are of structural, chemical, electrochemical, and biochemical significance. Sulfur bridged organometallic clusters have made possible several new basic metal cluster reactions. ...
