On the acoustic scattering amplitude for a multi-layered Scatterer [PDF]
AbstractWe consider the boundary-value problems corresponding to the scattering of a time-harmonic acoustic plane wave by a multi-layered obstacle with a sound-soft, hard or penetrable core. Firstly, we construct in closed forms the normalized scattering amplitudes and prove the classical reciprocity and scattering theorems for these problems.

Decoding the Structure of Benzodithiophene Polymers for High‐Efficiency Organic Solar Cells
This study reveals a unique solid mesophase in top‐performing benzodithiophene‐based polymers for solar cells, comprising stacked solid‐like and liquid‐like layers. Combining nanoscale fibrillar domains with amorphous regions, it introduces a new structural paradigm.

Tuning the Hydrogen Bond Network Inside the Helmholtz Plane for Industrial Hydrogen Evolution
The hydrogen bond network within the Helmholtz plane, a key component affecting the hydrogen evolution kinetics, remains far from having a consensus owing to the lack of fundamental understanding. Herein, it is discovered that the introduction of the atomic electric field generated by the weak Ru─Ga bonds can further improve the proportion of 4 ...

A Monte Carlo approach to the 4D scattering equations
The scattering equation formalism is a general framework for calculation of amplitudes in theories of massless particles. We provide a detailed introduction to the 4D scattering equation framework accessible to non-experts, outline current difficulties ...

A photocurable latex system enables high‐resolution vat photopolymerization of water‐dispersed thermoplastics, yielding pseudothermoplastic materials with recyclability. The formulation permits precise control over mechanical properties and supports reprocessing through conventional and extrusion‐based methods. Compatibility with two‐photon 3D printing

Ultrasoft Iontronics: Stretchable Diodes Enabled by Ionically Conductive Bottlebrush Elastomers
This work introduces a solvent‐free, ultrasoft, and stretchable ionic diode based on oppositely charged bottlebrush elastomers (BBEs). The BBE diode exhibits an ultralow Young's modulus (<23 kPa), a high rectification ratio of 46, and stretchability over 400%.

Projectivity of planar zeros in field and string theory amplitudes
We study the projective properties of planar zeros of tree-level scattering amplitudes in various theories. Whereas for pure scalar field theories we find that the planar zeros of the five-point amplitude do not enjoy projective invariance, coupling ...

Nanodiamond‐Infused Microgels for pH‐Tunable Rheology, Lubrication, and UV Protection
Microgels consisting of swollen polyacrylic acid polymer networks, impregnated with nanodiamonds provide protection from ultraviolet (UV) radiation harmful to human health. Nanodiamonds enable UV blockage and control of the rheology (flow) and lubrication (skin‐feel) of these microgel‐skincare‐mimics.
