Photoluminescence of Te‐Doped Double Perovskite Cs2ZrCl6 Nanocrystals Versus Bulk: Insights From Temperature‐Dependent Spectroscopy

open access: yesSmall, EarlyView.
The optical properties of doped‐double perovskites Cs2ZrCl6:Te4+, both the form of nanocrystals (NCs) and bulk powders, are studied and compared. The PLQY of the doped‐NCs decreases with a decrease in size, which contrasts with what is typically observed for semiconductor QDs.

Unveiling the Charge Storage Mechanism of High‐Performance LiV₃O₈ Cathode for Mn2+/H+ Hybrid Batteries

open access: yesSmall, EarlyView.
In this study, LiV₃O₈ is explored as a cathode for an aqueous Mn2⁺/H⁺ hybrid battery. It delivers a high capacity of 204.58 mAh g−1 and retains 76.2% after 7000 cycles. Detailed analyses reveal the charge storage mechanism involving proton intercalation and limited Mn2⁺ diffusion due to high migration barriers.

A Kinetic Model of Antigen‐Dependent IgG Oligomerization and Complement Binding

open access: yesSmall Science, EarlyView.
A kinetic model capable of predicting IgG oligomerization, a key step in activating the classical complement pathway (CCP) of the immune system, is presented. The impacts of IgG subclass, concentration, and antigen density are analyzed using advanced biophysical techniques.

Coefficient bounds for certain classes of bi-univalent functions

open access: yesHacettepe Journal of Mathematics and Statistics, 2015
In this paper, we introduce two new subclasses of the function class Σ of bi-univalent functions defined in the open unit disk. Furthermore, we find estimates on the coefficients |a2| and |a3| for functions in these new subclasses.

Exploring the Modulation of the Complex Folding Landscape of Human Telomeric DNA by a Low Molecular Weight Ligand

open access: yesChemistry – A European Journal, Volume 31, Issue 32, June 6, 2025.
Time‐resolved nuclear magnetic resonance (NMR) and circular dichroism (CD) spectroscopy were utilized to investigate the complex G‐quadruplex folding landscape of the human telomeric DNA in the presence of the ligand Phen‐DC3. Our findings revealed significant differences in the kinetics of the pathways originating from the unfolded or K+‐bound state ...

A new general subclass of analytic bi-univalent functions

open access: yesTURKISH JOURNAL OF MATHEMATICS, 2019
In a very recent work, Seker [Seker B. On a new subclass of bi-univalent functions defined by using Salagean operator. Turkish Journal of Mathematics 2018; 42: 2891-2896] defined two subclasses of analytic bi-univalent functions by means of Salagean differential operator and he obtained the initial Taylor-Maclaurin coefficient estimates for functions ...

Lipid‐Hybrid Multicompartment Membrane Systems for Controlled, Compartmentalized Encapsulant Release

open access: yesAdvanced Materials Interfaces, Volume 12, Issue 11, June 9, 2025.
Herein a bio‐inspired, lipid‐hybrid‐based multicompartmental material for scalable (milliliter) microencapsulation (20 – 200 µm) and controlled release of aqueous solutions is presented. The multicompartmental architecture provides non‐mixing environments, spatial patterning of encapsulants, and controlled compartmentalized release by surfactant ...
