Hierarchical MXene‐Derived NTP/C Nanohybrids for Cryogenic Sodium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A hierarchical MXene‐derived NaTi2(PO4)3/C nanohybrid enables efficient sodium‐ion storage down to −40°C by integrating fast ion–electron transport pathways with an ether‐based electrolyte. The system promotes dominant pseudocapacitive behavior and forms a robust inorganic‐rich SEI, collectively mitigating kinetic and interfacial limitations, thereby ...

Submicron Metasurface Reconfigured Multiband Smart Windows

open access: yesAdvanced Functional Materials, EarlyView.
This work presents a submicron metasurface reconfigured multiband thermochromic smart window. By integrating subwavelength nanostructures into a Fabry−Perot resonator configuration, it mitigates conventional trade‐offs to simultaneously deliver high luminous transmittance and robust solar heating and radiative cooling modulation capabilities ...

Reflection coefficient for a lossy liquid–lossless isotropic solid interface

open access: yes, 1979
A theoretical treatment of the reflection problem at a lossy liquid–lossless isotropic solid is given. The calculation results indicate that the reflection coefficient has a peak greater than unity.

Giant Magnetic Coercivity Driven by Spin‐Bag Ferromagnetism in Epitaxial Sr3YCo4O10+δ Films with Engineered 2D Oxygen Vacancy Ordering

open access: yesAdvanced Functional Materials, EarlyView.
A giant magnetic coercivity and a vertical shift of hysteresis loops are demonstrated in Sr3YCo4O10+δ epitaxial films. The hard magnetic behavior originates from ferromagnetic spin bags stabilized within a long‐range ordered oxygen‐vacancy structure.

Phased Beam Tracing Method Using the Reflection Coefficient Calculated from the Absorption Coefficient

open access: yes, 2005
The phased beam tracing method (PBTM) is a technique which can calculate the pressure impulse response instead of energy impulse response, by taking the phase information into account. Inclusion of the phase information can extend the application of beam

The reflection coefficient of a fractional reflector

open access: yes, 2023
This paper considers the question of characterizing the behavior of waves reflected by a fractional singularity of the wave speed profile $c(x_1)=c_0(1+((\frac{x_1}{l_0})_+)^{\alpha})^{-\frac12}$. We first focus on the case of one spatial dimension and a

Sustainable Electrochemical Synthesis of High‐Quality MXenes: Mechanistic Insights, Applications, Challenges, and Technological Prospects

open access: yesAdvanced Functional Materials, EarlyView.
Electrochemical etching provides an eco‐friendly alternative to hazardous HF methods for MXene production. This approach facilitates the selective isolation of the A‐layer from MAX phases with tunable surface terminations. Controlling voltage, electrolytes, temperature, and duration enables the optimal structural integrity. Nevertheless, existing scale

Multidimensional Cellular Micro‐Compartments to Model Invasive Lobular Carcinoma Dormancy

open access: yesAdvanced Healthcare Materials, EarlyView.
Invasive lobular carcinoma (ILC) is an understudied subtype of breast cancer that is susceptible to late recurrences. In this study, micro‐compartmentalization techniques spanning multiple dimensions, including 2D, pseudo‐3D, and 3D, are integrated to uncover the mechanisms underlying ILC dormancy, revealing the central role of p27Kip1.

Self-scaling properties of the reflection coefficient of Cantor prefactal multilayers

open access: yes, 2003
We highlight the self-familar features of the frequency-dependent (absolute) reflection coefficient of a dielectric Cantor prefractal obtained by applying the well-known Cantor-set construction to the optical (rather than physical) layer lengths.
