Advances in Chitosan Nanoparticles: A Comprehensive Review of Properties, Synthesis, Characterization, Multidisciplinary Applications, and Future Perspectives

Journal of Applied Polymer Science, EarlyView.
This review highlights the synthesis of chitosan nanoparticles from natural sources, the thorough characterization of them, and use of microscopic and spectroscopic methods. It emphasizes that it has some indispensable properties such as being non‐toxic, antimicrobial, and capable of controlled drug release.

Effect of Annealing Temperature on the Structural, Morphological, and Optical Properties of CdSeTe Nanoparticles for Optoelectronic Applications

Advanced Physics Research, EarlyView.
A correlation between thermal treatment and enhanced crystalline quality, surface morphology, and optical response. As annealing temperature increases, structural refinement (evidenced by phrase transition from hexagonal to cubic), and more defined morphology (seen via SEM), and improved optical absorption and bandgap tuning (UV–vis and PL spectra) are

7000 Years of Aboriginal Mining at Sugarloaf Hill in the Riverland Region of South Australia

Archaeology in Oceania, EarlyView.
ABSTRACT Silcrete and chert are commonly represented in Aboriginal archaeological lithic assemblages across large parts of the southwestern Murray‐Darling Basin (MDB). In South Australia (SA), these materials were sourced from a series of quarries located along the incised course of the Murray River through the upper Riverland region.

Bracketing the Age of Freshwater Carbonate Formation by OSL Dating Near Lake Kolon, Hungary

Journal of Environmental Geography, 2014
Freshwater carbonates are unique depositions in the centre of the Carpathian Basin, with debated origin and age. Their formation on the sand covered area of the Danube-Tisza Interfluve is mainly related to lakes appearing in low lying interdune areas ...

Atomically precise metal cluster enzymes for pathological tissue regeneration

BMEMat, EarlyView.
Schematic illustration of atomically precise metal cluster enzymes (MCEs) for pathological tissue regeneration. Atomically precise MCEs can modulate biological processes, such as attenuation of inflammatory responses, eradication of bacterial pathogens, regulation of angiogenesis, and promotion of cell development.

Narrowband Macrocycles: A New Paradigm for High‐Color‐Purity Organic Light‐Emitting Diodes

FlexTech, EarlyView.
This graphical abstract illustrates two key strategies for constructing macrocyclic multi‐resonance (MR) emitters for high‐performance OLEDs: (1) the covalent assembly of MR moieties onto macrocyclic scaffolds, and (2) the local multi‐resonance strategy within the macrocyclic backbone.

Not too old to rock: ESR and OSL dating reveal Quaternary activity of the Periadriatic Fault in the Alps

Earth, Planets and Space
The Periadriatic Fault system (PAF) ranks among the largest post-collisional structures of the European Alps. Recent geodetic data suggest that a fraction of the Adria–Europe convergence is still being accommodated in the Eastern Alps.
