Elasticity‐Driven Periodic Polarization Patterns in a Chiral Ferroelectric Nematic Fluid

open access: yesAdvanced Materials, EarlyView.
Chiral polar ferroelectric nematic fluids exhibit spontaneous formation of stripe, square, and hexagonal polarization textures under confinement. Controlled by thickness and anchoring, these patterns produce spatially modulated nonlinear optical responses.

Radiative Thermal Management for Extreme Environments: Mechanisms and Design Strategies

open access: yesAdvanced Materials, EarlyView.
In this review, we discuss the fundamental mechanisms of radiative cooling and solar heating, material and structural design strategies, hybrid approaches integrating additional heat transfer pathways, and durability‐oriented designs addressing environmental stresses.

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.

Microgels Enable iPSCs to Assemble, Expand, and Differentiate Into Organoids—From Sizable to High‐Throughput

open access: yesAdvanced Materials, EarlyView.
A chemically defined PEG‐based microgel platform enables scalable, reproducible production of three‐dimensional microgel‐iPSC constructs in multiple sizes. The system is compatible with high‐throughput automation and supports human iPSC expansion and differentiation within a single construct, including directed differentiation into cardiac organoids ...

Increasing Lipid Nanoparticle mRNA Copy Number Improves Transfection Potency

open access: yesAdvanced Materials, EarlyView.
As lipid nanoparticle (LNP) systems are the leading platform for in vivo nucleic acid delivery, improving transfection potency of these systems is of considerable interest. In this work, we explored a post‐mixing formulation method involving a two‐step buffer exchange that increased the number of mRNA copies within each LNP while reducing the number of

A necessary and sufficient condition for the existence of positive solutions to singular boundary-value problems of higher order differential equations

open access: yesElectronic Journal of Differential Equations, 2006
By constructing some special cones and using fixed point theorem of cone expansion and compression, this paper presents some necessary and sufficient conditions for the existence of $C^{4n-2}$ positive solutions to a class of singular boundary-value

Reactivity‐Guided Janus Graphene With Asymmetric Interfacial Electrostatics for Tunable Charge Transport

open access: yesAdvanced Materials, EarlyView.
Stepwise dual‐side functionalization creates covalent Janus graphene with chemically and electrostatically asymmetric interfaces. The resulting nonadditive surface‐potential response and pronounced charge‐transport modulation demonstrate a versatile route for tailoring the electronic properties of graphene.

Three positive solutions for a system of singular generalized Lidstone problems

open access: yesElectronic Journal of Differential Equations, 2009
In this article, we show the existence of at least three positive solutions for the system of singular generalized Lidstone boundary value problems $displaylines{ (-1)^m x^{(2m)}=a(t)f_1(t,x,-x'',dots,(-1)^{m-1}x^{(2m-2)},y,-y'',cr dots,(-1)^{n-1}y^{
