Effect of Varying Levels of Dietary 1, 3 Butanediol on Growing Chicks

open access: yesPoultry Science, 1969
Abstract THE incorporation of synthetic nutrients in poultry rations has been limited to amino acids, vitamins and other ingredients not normally classified as energy sources. Within the last few years a new area of study has developed concerning the use of man made compounds as energy contributors in poultry diets.

Recent Progress in the Phase‐Controlled Synthesis of Ruthenium Nanocrystals for Catalytic Applications

open access: yesAdvanced Materials, EarlyView.
Template effect and kinetic control enable crystal‐phase engineering of Ru nanocrystals, granting access to either metastable fcc‐Ru or stable hcp‐Ru with distinct surface structures, thermal stabilities, and catalytic behaviors. Moreover, the hcp‐Ru can further serve as an epitaxial template to direct Pd and Rh nanocrystals into the metastable hcp ...
