Borel series approach to subclasses of univalent analytic functions

Frontiers in Applied Mathematics and Statistics
The theory of analytic and univalent functions occupies a central position in geometric function theory because of its rich mathematical structure and its connections with various areas of complex analysis and applied analysis.

Polarity‐Controlled Coexistence of Electrochemical Metallization and Valence Change Mechanisms in a Unified Metal Halide Perovskite Memristor

Advanced Science, EarlyView.
Electrochemical metallization and valence change mechanisms are shown to coexist within a single metal halide perovskite memristor, selectively activated by simply reversing the electroforming voltage polarity. Ag‐driven switching delivers low operating voltages and high endurance, while intrinsic ion migration yields superior retention and resistance ...

Ligand‐Directed Molecular Beacons as Turn‐On Fluorescent Probes for Sensing Cell‐Surface Receptor‐Ligand Interactions

Angewandte Chemie, EarlyView.
Multivalent, ligand‐directed molecular beacons enable fluorescence turn‐on detection of cell‐surface receptors in living cells. The probes strongly engage closely spaced membrane receptors and exhibit conformation‐dependent fluorescence enhancement at the cell surface, enabling wash‐free receptor imaging, inhibitor screening, and functional evaluation ...

Ionically Counter‐Programmable Phase‐Separation of Superstable Star‐Biopolyamide Coacervates for Electrothermally‐Responsive Pseudosolid Smart Windows

Advanced Science, EarlyView.
We develop bio‐based, star‐branched polyamides from itaconic acid and cadaverine with tunable lower critical solution temperature (LCST) transitions for dynamic solar modulation. Specific metal ion coordination with pyrrolidone moieties drives precise phase transitions via calcium‐induced salting‐in and sodium‐induced salting‐out mechanisms. Formulated

Time‐Resolved Multidimensional NMR Spectroscopy Reveals the Bifurcated Folding Pathway of a Thrombin‐Binding DNA G4–Azobenzene Derivative Complex

Angewandte Chemie, EarlyView.
A photoswitchable ligand was used to trigger conformational changes within the thrombin binding aptamer DNA G‐Quadruplex. These reversible ligand driven rearrangements were examined by time‐resolved NMR experiments to gain insight of the dynamic folding landscape of the G‐quadruplex.

Construction of Planar Harmonic Functions

International Journal of Mathematics and Mathematical Sciences, 2007
Complex-valued harmonic functions that are univalent and sense-preserving in the open unit disk can be written in the form f=h+g¯, where h and g are analytic in the open unit disk.

Polyphosphate Copper Nanospheres Drive Mitochondrial Metabolic Reprogramming via Calcium Phase Separation for Self‐Sensitizing Cuproptosis

Advanced Science, EarlyView.
This study developed polyphosphate (polyP)‐based nanostructures that enable calcium‐mediated metabolic reprogramming via liquid–liquid phase separation (LLPS). Released polyP undergoes LLPS with Ca2+, suppressing glycolytic flux and enhancing mitochondrial metabolism effectively.

Adaptation of a Fluorogenic RNA to N1‐Methylpseudouridine Nucleoside Chemistry

Angewandte Chemie, EarlyView.
Several green‐emitting fluorogenic RNA aptamers were evaluated following the replacement of every uridine by N1‐methylpseudouridine (mΨ). Because this modification impaired the function of most aptamers, a directed evolution strategy combining droplet microfluidics, bioinformatics, and rational design was used to identify an aptamer preserving its ...
