A coefficient problem of Bombieri concerning univalent functions
, 1984 We answer affirmatively a question raised by Bombieri concerning the behaviour of the coefficients of normalized univalent functions near the Koebe function.

Nonlinear Ion‐Specific Control of Underwater Adhesion by Bottlebrush Polymer Interfaces
Advanced Science, EarlyView.The efficiency of underwater adhesion is modulated by ion‐specific effects. Strongly hydrated Na+ remains separated from the mica surface by its hydration shell, preserving access to binding sites, whereas weakly hydrated K+ can partially dehydrate and occupy ditrigonal cavities.

Stabilizing Functional Nucleic Acids for Real‐Sample Diagnostics
Angewandte Chemie, EarlyView.Functional nucleic acids enable programmable real‐sample diagnostics, but often lose function in complex biological matrices. This review highlights four stabilization levers—chemical, topological, architectural, and microenvironment/interface engineering—that preserve aptamer and DNAzyme performance in saliva, serum, urine, and stool, reframing ...

Inequalities for the classes of analytic functions defined using subordination
Mathematics OpenIn this paper, we have defined a new family of analytic functions associated with an exponential function. The analytic characterization of this new class is motivated by a subordination condition that was instrumental in establishing the starlikeness ...

Advanced Science, EarlyView.Receptor‐triggered supramolecular self‐assembly converts monovalent antibody‐recruiting molecules into multivalent platforms directly on cancer cell membranes. The resulting fibrillar assemblies present clustered haptens that efficiently recruit endogenous antibodies, enabling selective complement‐mediated immune killing of EGFR‐positive cancer cells ...

The (p, q)-chebyshev polynomial bounds of a general bi-univalent function class
, 2020 In the present paper, we will define the bi-univalent function class S.,mu S ( p, q) related to the ( p, q)-Chebyshev polynomials. Then we will derive the ( p, q)-Chebyshev polynomial bounds for the initial coefficients and determine Fekete-Szego ...

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 ...

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 ...

Birth of the theory of univalent functions
, 1998 "Univalent" is the complex analyst's term for "one-to-one" functions. A univalent function has a non-vanishing derivative. Riemann Mapping Theorem stated in 1851 could not find some interesting applications until P.
