Leveraging Multifaceted Polyphenol Interactions: An Approach for Hair Loss Mitigation

Advanced Materials Interfaces, EarlyView.
This study presents tannic acid as an effective alternative to traditional hair loss treatments. Acting as an adhesion mediator, tannic acid binds to keratin on the hair surface and sequesters SCANDAL—a blend of salicylic acid, niacinamide, and dexpanthenol—allowing gradual release to hair follicles.

Model selection techniques for seafloor scattering statistics in synthetic aperture sonar images of complex seafloors

IET Radar, Sonar & Navigation
In quantitative analysis of seafloor scattering measurements, it is common to model the single‐point probability density function of the scattered intensity or amplitude.

Atomic Layer Deposition of ZnO Coating on Biodegradable Fe‐Based Alloys

Advanced Materials Interfaces, EarlyView.
A biodegradable Fe69Mn30C1 alloy is coated with ZnO using atomic layer deposition at 100 °C. Coating thickness impacts surface roughness, wettability, and in vitro degradation while maintaining hydrophilicity. The ZnO coating exhibits significant antibacterial activity against Staphylococcus aureus, achieving an inhibitory rate of up to 99.2%, and can ...

Time‐ and Frequency‐Domain THz Imaging for the Characterization of Subwavelength Tags in Anticounterfeiting Devices

Advanced Materials Technologies, EarlyView.
Anticounterfeiting optical devices typically rely on random surface patterns revealed under IR/vis/UV light. Despite its security, this method suffers from the unavoidable deterioration of exposed superficial patterns. The proposed technique utilizes the high penetration depth and resolution of THz radiation to reveal submillimeter metallic patterns ...

Transforming Room Acoustics with Causality‐Driven Dual‐Function Passive Metamaterials

Advanced Materials Technologies, EarlyView.
This work presents an dual acoustic metamaterial for rooms that achieves excellent broadband performance for both sound absorption and sound diffusion. This is done by using causality formulations linking the absorption of the passive system to its volume, yielding an optimal surface area ratio required for excellent sound absorption and while ...

Reconstruction of the reverberation theory in a diffuse sound field by using reflection orders [PDF]

arXiv
Room acoustics is mainly based on the reverberation theories of Saine and Eyring. In Sabine's theory however, the reverberation time does not reach zero, even if the condition of absolute absorption is fulfilled. Eyring revised reverberation theory to resolve this contradiction.

A Numerical Strategy for Achieving Efficiency Exceeding 32% with a Novel Lead‐Free Dual‐Absorber Solar Cell Using Ca3SbI3 and Sr3SbI3 Perovskites

Advanced Photonics Research, EarlyView.
This study develops a highly efficient, lead‐free perovskite solar cell featuring a dual‐absorber system composed of Ca3SbI3 and Sr3SbI3, with SnS2 as the electron transport layer and Spiro‐OMeTAD as the hole transport layer. The proposed double perovskite structure exhibits outstanding power conversion efficiency of 32.74% with a JSC of 34.17 mA cm−2,

The multifactorial aquaculture‐related COVID‐19 shock in Benin, West Africa: A socio‐economic perspective of mitigating the disruptive impacts on the small‐scale and subsistence producers

Aquaculture, Fish and Fisheries, Volume 2, Issue 6, Page 507-521, December 2022., 2022
Graphical Abstract This study deals with a timely topic, COVID‐19, whose impacts on aquaculture have never been quantified in Benin. Direct discussions were held with aquaculture producers to understand how they are feeling the impact of the pandemic on their business.
