Modulating Electromagnetic Genes Through Bi-Phase High-Entropy Engineering Toward Temperature-Stable Ultra-Broadband Megahertz Electromagnetic Wave Absorption.

Magnetic absorbers with high permeability have significant advantages in low-frequency and broadband electromagnetic wave (EMW) absorption. However, the insufficient magnetic loss and inherent high conductivity of existing magnetic absorbers limit the further expansion of EMW absorption bandwidth. Herein, the spinel (FeCoNiCrCu)O high-entropy oxides (HEO) are successfully constructed on the surface of FeCoNiCrCu high-entropy alloys (HEA) through low-temperature oxygen bath treatment.

Carbon Nanocoils-Assisted Formation of Tunable Pore Graphene Aerogels for Lightweight Broadband Microwave Absorption, Thermal Insulation, and Antifreeze Devices.

The rational design of the aerogel pore structure facilitates the maximum excitation of the materials physicochemical properties, which enables the modulation of their electromagnetic performance. However, the controllable adjustment of the aerogel pore structure remains a significant challenge. Here, the freeze-thawing process and thermal annealing treatment are introduced to prepare reduced graphene oxide (rGO)/iron (Fe)/carbon nanocoil (CNC) aerogels.

Expressed emotion mediates the association between caregiver relationship closeness and psychological symptoms in people with dementia.

Aim: This study examines whether expressed emotion (EE) mediates the association between caregiver relationship closeness and behavioural and psychological symptoms of dementia (BPSD).

Methods: We recruited 64 families with dementia in Osaka and collected data for 3 months. Caregiver-patient relationship closeness was assessed using the Relationship Closeness Scale (RCS), and BPSD was measured with the Neuropsychiatric Inventory Questionnaire (NPI-Q).

A pilot study on the effects of in-feed probiotic ATCC 53103 (LGG) on vaccinated Atlantic salmon (): microbiomes and challenge resilience.

The use of probiotics is an alternative approach to mitigate the proliferation of antimicrobial resistance in aquaculture.

Anaerobic granular sludge performance in an expanded granular sludge bed reactor treating calcium-rich wastewater by adjusting CaCO crystallization: Effect of upflow velocity and Ca concentration.

The role of upflow velocity and Ca concentration in controlling the type and rate of CaCO crystallization and their impacts on the anaerobic granular sludge (AnGS) formation and performance in an expanded granular sludge bed (EGSB) reactor were studied. The results showed that an improved upflow velocity could promote metastable CaCO crystals and achieve the optimized portion of vaterite with a value of 84 % at 10 m/h with a small amount of aragonite, thus limiting the scaling in the reactor. The removal efficiency of Ca was to some extent positively correlated to the influent Ca concentration, but declined when Ca exceeded a specific threshold.

Delayed epiphyseal closure in an adult with panhypopituitarism detected by Tc-MDP bone SPECT/CT.

We reported a 23-year-old male patient with panhypopituitarism who underwent two resections for craniopharyngioma and received postoperative hormone replacement therapy. The Tc-MDP bone scan revealed focal high uptake of radioactive nuclide in multiple large joints. The SPECT/CT demonstrated the focal high uptake in their metaphysis.

Accelerating the granulation of anammox sludge in wastewater treatment with the drive of "micro-nuclei": A review.

Anammox granule sludge (AnGS) has great potential in the field of wastewater nitrogen removal, but its development and promotion have been limited by the slow granulation speed and fragile operating stability. Based on the reviews about the AnGS formation mechanism in this paper, "micro-nuclei" was found to play an important role in the granulation of AnGS, and adding "micro-nuclei" directly into the reactor may be an efficient way to accelerate the formation of AnGS. Then, accelerating AnGS granulation with inert particles, multivalent positive ions, and broken granule sludge as "micro-nuclei" was summarized and discussed.

Two-Dimensional Basalt/Ni Microflakes with Uniform and Compact Nanolayers for Optimized Microwave Absorption Performance.

It has been accepted that the uniform distribution of magnetic metal particles is beneficial to microwave absorption, while why the homogeneous magnetic particles on the dielectric substrate improve the electromagnetic loss is still unclear. Herein, metal Ni nanoparticles, two-dimensional (2D) basalt/scattered Ni, and basalt/uniform Ni microflakes are obtained through a pretreatment and electroless deposition process. In comparison to Ni nanoparticles and basalt/scattered Ni, the basalt/Ni microflakes with largely uniform and compact Ni nanolayers on basalt, breaking the percolation limit, are favorable for enhanced electromagnetic attenuation.

FeCoNiCrCu High-Entropy Alloys with Strong Intergranular Magnetic Coupling for Stable Megahertz Electromagnetic Absorption in a Wide Temperature Spectrum.

Electromagnetic (EM) absorbers serving in the megahertz (MHz) band and a wide temperature range (from -50 to 150 °C) require high and temperature-stable permeability for outstanding EM absorption performance. Herein, FeCoNiCrCu high-entropy alloy (HEA) powders with a unique nanocrystalline structure separated by a thin amorphous layer (NTA) are designed to improve permeability and enhance intergranular coupling. Simultaneously, the long-range anisotropy is introduced via devising the preparation process and tuning the chemical composition, such that the intergranular exchange interaction is further strengthened for stable permeability and EM wave absorption in a wide temperature range.
