Rare Mononuclear Lithium–Carbene Complex for Atomic Layer Deposition of Lithium Containing Thin Films

Angewandte Chemie International Edition, EarlyView.
A new N‐heterocyclic carbene (NHC) stabilized lithium complex is introduced as a thermally stable atomic layer deposition (ALD) precursor. It features a rare mononuclear structure, suitable volatility, and a low melting point of 55 °C. ALD trials yielded lithium silicate films.

Characterization and Beneficiation of Indigenous Marble Waste to Remove Siliceous and Ferrous Impurities

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In this study, marble waste (MARWAS) beneficiation was done using thermal, physical, and chemical means. The MARWAS samples collected from dumping yards of Kishangarh and Revdar districts of Rajasthan (India) and Ambaji district of Gujarat (India) were characterized by chemical composition analysis, scanning electron microscopy with energy ...

Green Composites From Plasticized Cellulose Acetate Filled With Inorganic Fillers and Natural Fiber for Rigid Packaging Applications: Effect of Low Acetyl Content and Bio‐Based Plasticizer

Journal of Applied Polymer Science, EarlyView.
Plasticized cellulose acetate (pCA) composites with talc and a small amount of Luperox show improved strength, flexibility, and barrier properties, making them promising biodegradable materials for rigid packaging applications. ABSTRACT This work aims to improve the processing window and melt strength of cellulose acetate (CA) with low acetyl content ...

Histovariability and fossil diagenesis of Pissarrachampsa (Pseudosuchia, Notosuchia, Baurusuchidae) from the Upper Cretaceous of Southeast Brazil

The Anatomical Record, EarlyView.
Abstract Notosuchians were key components of western Gondwanan Cretaceous ecosystems in terrestrial predator niches and exhibited remarkable taxonomic and ecological diversity. Previous research has explored their physiology, metabolism, and histology, revealing varied growth patterns and life history strategies.

Enhanced Production of Astaxanthin and Zeaxanthin by Paracoccus Sp. LL1 Through Random Mutagenesis

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Astaxanthin, a high‐value carotenoid with potent antioxidant and anti‐inflammatory activities, is increasingly in demand in various industries. This study reports the successful enhancement of astaxanthin and zeaxanthin production in Paracoccus sp. LL1 through random mutagenesis using ethyl methanesulfonate (EMS).
