Lubricating Characteristic of Grease Composites with CNT Additive

open access: yesTribology Online, 2011
The friction at high speed and high pressure tends to cause the lowering of grease stickiness because the frictional heating occurs at the sliding surface, which will bring to the degradation of lubricity.

Embryonic development of the Mediterranean starfish Hacelia attenuata

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Starfish play essential ecological roles as predators and ecosystem regulators; however, detailed developmental descriptions exist for only a handful of species, none of which are from the Mediterranean Sea. Results In this study, we provide the first full account of the development of the Mediterranean starfish Hacelia attenuata ...

Management considerations in grease versus non-grease scald burns in adults: A retrospective cohort study at a tertiary burn care facility

open access: yesBurns Open
Introduction: Scald burns are challenging to manage due to their evolutionary nature and nuanced injury pattern. Different mediums, such as hot water, steam, or grease, each have unique physical properties that may inflict more damage and incite a ...

Influence of Li Grease Thickener Types on Film Thicknesses Formed between Smooth and Dented Surfaces

open access: yesTribology Online, 2017
The lubricant film thickness behaviors of lithium (Li) thickener type greases and their base oil were investigated for the contact between a glass disk and a smooth/dented steel ball using an optical interferometry. The main focus is to understand grease

An accessible microfluidic perfusion platform for time‐restricted control of zebrafish embryonic patterning

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Understanding the dynamic nature of developmental networks requires live imaging techniques capable of capturing real‐time developmental processes in wild‐type and mutant embryos as they are exposed to pharmacological perturbations. A peculiar developmental patterning process in early vertebrate embryos is the sequential segmentation of ...

Effect of Additives on the Properties of Different Types of Greases

open access: yesIraqi Journal of Chemical and Petroleum Engineering, 2013
The aim of this research is to study the influence of additives on the properties of soap greases, such as lithium, calcium, sodium, lithium-calcium grease, by adding varies additives, such as graphite, molybdenum disulfide, carbon black, corrosion ...

The Hydrogenation of MNi3 Compounds (M = Si, Ge, Sn, Sb, Zr, V, Fe)

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Hexagonal Ni3Sn takes up hydrogen to form α‐Ni3SnHx (filled Ni3Sn type, ΔV = 0.9%), followed by a transition to the cubic β‐Ni3SnHy (filled AuCu3 type, ΔV = 1.1% with respect to pristine Ni3Sn), while MNi3 (M = Zr, Si, Sb) compounds show no reaction toward hydrogen and MNi3 (M = V, Fe, Ge) compounds only a minute hydrogen uptake.

A New High‐Pressure Polymorph of MgTe2O5 with a Unique Crystal Structure

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
MgTe2O5 synthesized under special high‐pressure/high‐temperature conditions of 8 GPa and 800 °C exhibits a unique crystal structure consisting of fused sechser rings built from pseudooctahedral [TeO5]6– and trigonal‐pyramidal [TeO3]2– units. The single‐crystal structure and temperature‐dependent powder diffraction data are presented.

Nutritional, Functional, and Anti‐Hypercholesterolemic Properties of Sourdough Breads From Unripe Plantain, Tiger Nut, and Fenugreek Flours

open access: yesFood Chemistry International, EarlyView.
Composite sourdough breads were developed from blends of unripe plantain, tiger nut, and fenugreek flours. Optimized formulations improved pasting stability and enhanced texture, producing softer more elastic crumbs. The enriched breads contained higher dietary fiber and bioactive compounds, and significantly reduced serum cholesterol markers ...
