Bio-Lubricants Development: The Potential Use of Boron-Containing Additives [PDF]

, 2012
This paper reports the use of boron-containing additives to improve the performance of a bio-based lubricating oil. The base oil was prepared from glycerol and oleic acid, was fortified with antifoaming agent, phenyl-α-naphtylamine, 4,4’-methylene-bis(2 ...

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy

Advanced Engineering Materials, EarlyView.
This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...

Poly(iminoborane)s with Aromatic Side Groups: Insights into the Microstructure from Monodisperse Model Oligomers

ChemistryEurope
While certain inorganic main‐group polymers such as silicones (polysiloxanes) are ubiquitous in our everyday life, poly(iminoborane)s have been elusive for a long time.

Effects of boron deficiency and low temperature on wheat sterility [PDF]

, 1996
Wheat exhibits sterility in many parts of subtropical and tropical Asia. Boron deficiency is believed to be the cause of sterility in many, but not all, cases.

Conformal CVD of boron-rich BxC thin films from triethylboron [PDF]

, 2022
We report conformal chemical vapor deposition (CVD) of boron carbide thin films on silicon substrates with 8:1 aspect-ratio morphologies, using triethylboron (TEB, B(C2H5)3) as single source CVD precursor.

High‐Temperature Nanoindentation of Metals: Assessing Thermal Drift, Frame Compliance, and Chemical Composition Effects on the Reported Mechanical Properties

Advanced Engineering Materials, EarlyView.
Do not let thermal drift and instrument artifacts deceive high‐temperature nanoindentation results. We compare classical Oliver–Pharr and automatic image recognition analyses across steels and a Ni alloy to quantify these effects. Accounting for artifacts reveals systematic softening with temperature, while Cr and Ni additions boost resistance ...

Nickel(0)‐Catalyzed [2+2+2] Cycloadditions of Linked Bisdiynes with Diaryl Alkynes Generates D‐π‐A‐π‐D Bis(arylethynyl)indane‐Based Organic Frameworks as Noncytotoxic Probes for Ds‐DNA/Ds‐RNA

ChemistryEurope
Nickel(0)‐catalyzed [2 + 2 + 2] cycloadditions of linked bisdiynes with diarylacetylenes were performed using the Ni(II) precursor complex [(TMEDA)Ni(o‐tolyl)Cl] in the presence of PPh3 ligands to generate the active Ni(0) species. Optimal reactivity was

Ultrathin Boron Growth onto Nanodiamond Surfaces via Electrophilic Boron Precursors [PDF]

Diamond as a templating substrate is largely unexplored and the unique properties of diamond including its large bandgap, thermal conductance and lack of cytotoxicity make it versatile in emergent technologies in medicine and quantum sensing.
