Relativistic effects on chemical properties [PDF]

Accounts of Chemical Research, 1979
Special or anomalous chemical effects are examined in relation to periodic-table trends, and the degree to which these are relativistic effects are determined. It is noted that the degree to which these relativistic effects and the introduction of 4f electrons (the usual textbook explanation of the anomalies) affect chemical behavior are of approx ...

Tetragonal zirconia: Wet chemical preparation, mechanical and electrical properties [PDF]

, 1985
Yttria-stabilized zirconia powders were prepared in the composition range of 3 to 13 at% yttria. The hydrolysis-gel precipitation technique was used, starting from metal alkoxides or chlorides.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Developing new chemical–rheological models and chemical–durability indices of bitumen [PDF]

, 2013
Significant correlation among chemical properties, rheological characteristics and durability of bitumen is very important in evaluating and modifying bitumen. However, a number of previous studies found inconsistent correlation.
