Optimizing Thermoelectric Efficiency in La_(3−x)Te_4 via Yb Substitution [PDF]

, 2010
A low temperature, solid state synthesis technique has enabled the production of homogeneous samples of La_(3−x−y)Yb_yTe_4. This allows the substitution of divalent Yb to be utilized to optimize the thermoelectric performance in lanthanum telluride.

Nanoscale assembly of lanthanum silica with dense and porous interfacial structures [PDF]

, 2015
This work reports on the nanoscale assembly of hybrid lanthanum oxide and silica structures, which form patterns of interfacial dense and porous networks. It was found that increasing the molar ratio of lanthanum nitrate to tetraethyl orthosilicate (TEOS)

Superconductivity of Lanthanum and Some Lanthanum Alloys

Physical Review, 1958
Superconductivity has been observed for two structures of lanthanum. A close-packed hexagonal structure was found to have a transition temperature near 5.0\ifmmode^\circ\else\textdegree\fi{}K and the face-centered cubic structure had a transition temperature of 5.95\ifmmode^\circ\else\textdegree\fi{}K.

Design of a Cobalt‐Free Maraging Steel with Ultra‐High Strength of 2.3 GPa Through Additive Manufacturing

Advanced Science, EarlyView.
A computationally designed, cobalt‐free maraging steel tailored for additive manufacturing achieves an ultra‐high tensile strength of 2.3 GPa with 5.7% elongation. This exceptional strength‐ductility synergy stems from high‐density core‐shell Ni3Ti/NiAl nanoprecipitates, a crack‐resistant composition, and a fine equiaxed grain structure enabled by ...

Incommensurability and spin excitations of diagonal stripes in cuprates

, 2009
Based on the time-dependent Gutzwiller approximation we study the possibility that the diagonal incommensurate spin scattering in strongly underdoped lanthanum cuprates originates from antiferromagnetic domain walls (stripes).

Enhancing Cycling Stability of Aqueous Aluminum‐Metal Batteries via LaCl3‐Modulated Interfacial Reactions

Advanced Science, EarlyView.
In the aqueous AlCl3 electrolyte of aluminum‐metal batteries, the introduction of LaCl3 adjusts the solvation structure of Al3+ and enhances its diffusion level. The oxide precipitate formed by La3+ covers the aluminum metal anode and effectively alleviates corrosion reactions, thereby improving the cycling stability of the battery.
