Lanthanum-Catalyzed Regioselective Anti-Markovnikov Hydrophosphinylation of Styrenes

open access: yes, 2019
A useful and convenient method for sp3 C–P­(O) bond formation via direct regioselective hydrophosphinylation of simple and readily available alkenes using a lanthanum-based N,N-dimethylbenzylamine complex (La­(DMBA)3) as a precatalyst is demonstrated ...

Emerging locally delivered antimicrobial and immunomodulatory approaches for the prevention/treatment of peri‐implant diseases

open access: yesPeriodontology 2000, EarlyView.
Abstract Peri‐implant diseases are dysbiosis‐mediated inflammatory disorders that occur in susceptible hosts. Antimicrobials and immunomodulatory agents therefore might be pertinent as adjunctive measures in the treatment of such disorders. The aim of this narrative review was to examine the existing evidence and assess the effectiveness of emerging ...

Early results and lessons learned from biomanipulation and chemical restoration of a eutrophic shallow lake

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Over 44% of European lakes fail to meet ecological quality standards, prompting substantial investment in lake restoration to achieve good ecological status. Unfortunately, effects are often short‐lived due to persistent internal phosphorus (P) loading and strong cyprinid‐driven bottom‐up control, which limits water quality ...

Lanthanum staining of cell surface and junctional complexes in normal and malignant human oral mucosa

open access: yes, 1975
Biopsies from normal and malignant human oral epithelium were studied electron histochemically using lanthanum nitrate for a selective demonstration of junctional complexes at the plasma membrane of adjacent cells.

Electrolysis‐treated biosolids enhance wheat growth and alter soil health parameters

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 4, December 2026.
Abstract Biosolid‐based fertilizers can benefit agriculture by supporting circular nutrient economies, reducing fertilizer costs, and minimizing environmental impacts compared to inorganic fertilizers. A 125‐day greenhouse experiment was conducted to assess the effects of electrolysis‐treated biosolids on wheat (Triticum aestivum) growth and soil ...

Perovskite‐Based Catalysts for the Oxygen Evolution Reaction: Synthesis, Device Relevant Performance, and Scale‐Up Strategies

open access: yesSmall, Volume 22, Issue 61, 2 November 2026.
Perovskites are emerging as catalysts for acidic oxygen evolution in proton exchange membrane water electrolyzers. This manuscript focuses on catalyst behavior under device‐relevant conditions, highlighting surface reconstruction, elemental utilization, and membrane electrode assembly performance. By linking materials design with electrolyzer operation,

Lanthanum-substituted CaMo-MOF via controlled metal nitrate ratios for Electrochemical Performance

open access: yesGiant
In this study, a series of LaxCa1-xMo-based metal-organic frameworks (MOFs), designated as CML1, CML2, CML3 and CML4, were synthesized via a controlled precipitation method.

Characterization and adsorption properties of La and Fe modified activated carbon for dye wastewater treatment

open access: yesGreen Processing and Synthesis, 2017
An effective adsorbent (Fe-La-AC) was synthesized by impregnating mixed solution ferric nitrate and lanthanum nitrate with activated carbon and heated by microwave to remove methylene blue (MB) from dye wastewater.

Adjustment of Root System Architecture and Root Function in Response to Multifactorial Abiotic Stress

open access: yesPhysiologia Plantarum, Volume 178, Issue 6, November/December 2026.
ABSTRACT The root of land plants is a remarkably adaptive organ. Unlike the shoot with its main functions in light harvesting and photosynthesis, sexual reproduction and diaspore distribution, the root explores the soil for nutrient resources and water, while preferably avoiding zones of unfavorable conditions. Roots realize an extraordinarily flexible
