Halide Composition Controls Phase Morphology and Device Specific Performance in Perovskite Photovoltaics and Light Emitting Diodes

open access: yesAdvanced Functional Materials, EarlyView.
We demonstrate that halide composition determines phase morphology, governing distinct operating mechanisms in mixed halide perovskites. Phase segregating 75% Br compositions enhance solar cell performance, whereas intrinsically phase‐separated 95% Br compositions provide stable light emitting diodes.

Endosomal Escape of siRNA Polyplexes: A Molecular Dynamics Perspective on Underlying Mechanisms

open access: yesAdvanced Functional Materials, EarlyView.
Molecular dynamics simulations reveal distinct endosomal escape mechanisms of siRNA nanoparticles, ranging from electrostatic membrane attachment to hydrophobic membrane fusion. Hydrophobic residues and anionic endosomal lipids emerge as key determinants of membrane disruption, linking molecular interactions to experimental delivery performance and ...

Gonadotropin‐Inhibitory Hormone (GnIH) and Its Receptor GPR147 Mediates Acute Stress‐Induced Activation of the Locus Coeruleus‐SAM Axis [PDF]

open access: yesAdvanced science
ABSTRACT Gonadotropin‐inhibitory hormone (GnIH, also known as RFamide‐related peptide‐3, RFRP‐3) is a hypothalamic neuropeptide that regulates vertebrate reproduction via its receptor GPR147. Although GnIH is known to mediate stress‐induced reproductive suppression, its role in broader stress responses remains unclear.

A Particle‐Level Dual‐Polymer Interphase for Coupled Interfacial and Contact Stabilization of Zinc Metal Powder Anodes in Aqueous Zinc‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A particle‐level dual‐polymer interphase of carboxymethyl cellulose (CMC) and poly(acrylic acid) (PAA) stabilizes zinc metal powder anodes by coupling CMC‐mediated water regulation with PAA‐derived Zn2+ affinity. This synergy suppresses hydrogen evolution, corrosion, and byproduct accumulation while preserving electrode‐level electrical contact ...

Phase Engineering of Atomically Precise Nanoclusters (APNCs) of Gold and Beyond

open access: yesAdvanced Materials, EarlyView.
Engineering the structural phase of materials is of paramount importance for both fundamental research and practical applications. In this Review, we summarize the recent progress in controlling the phases of atomically precise nanoclusters (APNCs) of gold, silver and copper, as well as bimetallic systems. The phase‐enabled material properties of APNCs

Epistemic Restraint and the Vice of Curiosity

open access: yes, 2012
In recent years there has been wide-ranging discussion of epistemic virtues. Given the value and importance of acquiring knowledge this discussion has tended to focus upon those traits that are relevant to the acquisition of knowledge.

Parity‐Dependent THz Harmonic Generation in Electrically Pumped Micro‐Lasers Exploiting Topological Insulator–Metamaterial Gratings

open access: yesAdvanced Materials, EarlyView.
Topological insulator–metamaterials integrated with electrically driven terahertz quantum cascade lasers enable parity‐dependent harmonic generation. Bulk‐dominated Bi2Se3 favors third‐harmonic emission at 9.96 THz, whereas topological‐surface‐state‐dominated Bi2Se3, Bi2Te3, and (Bi,Sb)2Te3 generate strong second harmonics near 6.5 THz.
