TRIVALENT CHROMIUM (CR+3) IN DIETARY CARBOHYDRATE AND ITS EFFECT ON THE GROWTH OF COMMONLY CULTIVATED FISH [PDF]

open access: yes, 2016
Trivalent chromium (Cr+3) is an essential trace mineral for fish bio-physiological functions. Researches on Cr+3 in the form of organic compound indicated that the mineral affected the bio-activity of insulin, the blood glucose influx, and subsequently ...

Oxidation kinetics of chromium and morphological phenomena [PDF]

open access: yes, 1989
The oxidation kinetics of chromium at 900°C are independent of the oxygen partial pressure. Although this observation gives evidence for a defect mechanism where chromium interstitials account for the chromium transport in the oxide scale, the ...

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Reaction layer formation at the graphite/copper-chromium alloy interface [PDF]

open access: yes
Sessile drop tests were used to obtain information about copper chromium alloys that suitably wet graphite. Characterization of graphite/copper-chromium alloy interfaces subjected to elevated temperatures were conducted using scanning electron ...

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Laser Metal Deposited Ti4822 Hollow Pipe: Experimental and Computational Modelling Study

open access: yesAdvanced Engineering Materials, EarlyView.
Laser metal deposition (LMD) of a crack‐free built Ti4822 alloys is challenging. This article reports outstanding characteristics of a hollow pipe that is built with LMD technology when a predicted, nontransformation substrate temperature of 800 °C is used.

Supplemental palmitic acid and chromium propionate influence production responses during the immediate postpartum in multiparous dairy cows

open access: yesJournal of Dairy Science
: Forty-eight multiparous Holstein cows were used in a randomized complete block design and assigned to 1 of 4 treatments in a 2 × 2 factorial arrangement of treatments to determine the effects of supplemental palmitic acid (C16:0) and chromium (Cr) on ...
