Stereoretentive Nucleophilic Aromatic Substitution Accesses Atropisomeric 4‐Amino‐N‐Arylquinolinium Salts

Chemistry – A European Journal, EarlyView.
Quinolin‐4‐ones were converted to chloroquinolinium salts, allowing formation of axially chiral aminoquinolinium salts via an enantioretentive SNAr reaction with a variety of amine nucleophiles. The salts have a high rotational barrier, with a racemization half‐life of ∼1000s of years.

On the Design of a Class of Analog Filters Whose Impulse Response Is a Mittag‐Leffler Function

International Journal of Circuit Theory and Applications, EarlyView.
Fractional‐order filters whose impulse response is a Mittag‐Leffler (M‐L) function in any of its known forms are summarized in this work. Simulation results using Cadence and experimental results using an FPAA validate the introduced concept. ABSTRACT Fractional‐order filters whose impulse response is a Mittag‐Leffler (M‐L) function in any of its known

Unveiling spatial heterogeneity in urban underground space development patterns and mechanisms for differentiated planning: A points of interest‐based study of Shanghai

Deep Underground Science and Engineering, EarlyView.
This study investigated the spatial patterns and development mechanisms of urban underground space (UUS) in Shanghai using underground points of interest data. It revealed distinct development mechanisms between the main city and suburbs, highlighting the need for differentiated UUS planning and policies to optimize underground space resources ...

Global distribution of avian plumage coloration and patterning: the relative influence of climate, ecology, and sexual selection

Ecography, EarlyView.
Animal coloration exhibits substantial biogeographic variation, reflecting complex adaptations to both abiotic and biotic environments. Although the evolutionary mechanisms underlying avian plumage coloration have been widely studied, geographic variation in plumage patterning has received far less attention.

Synergistic Modulation of Conductivity and Oxidation Stability in SiHfBCN Ceramics via UV‐Assisted Structural Evolution

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A quinary UV‐curable SiHfBCN ceramic photoresist with high ceramic yield enhanced is developed through sequential molecular design for high‐temperature sensing coatings. The elevated interconnected conductive network induced by chemically bonded carboxylated MWCNTs enables the pyrolyzed ceramics' enhanced conductivity and excellent oxidation stability.
