Advanced Science, EarlyView.Palatable food alleviates stress and prevents anxiety. This study uncovers a dedicated neural pathway: dopamine release in the PFC activates D1R neurons, whose projections to the peri‐PVN engage a population of anxiolytic CRFR1 neurons. These neurons then inhibit stress‐induced hyperactivity of PVNCRF neurons, providing a circuit‐level explanation for ...

Experimental Investigation of Radial Gas Dispersion Coefficients in a Fluidized Bed
Acta Polytechnica, 2012 In a fluidized bed boiler, the combustion efficiency, the NOX formation rate, flue gas desulphurization and fluidized bed heat transfer are all ruled by the gas distribution.

On the systematics of rheological measurements of gas fluidized grains [PDF]
EPJ Web of ConferencesThere have been many attempts to characterize the flow behavior of fluidized and non-fluidized granular particles [1–4]. The well-known Geldart classification [5] divides granular particles by their fluidization characteristics and the rheology of air ...

Advanced Science, EarlyView.An immunoregulatory hydrogel based on sodium ascorbate (SA)‐accelerated gelation and in situ self‐mineralization is prepared here. Such a hydrogel is constructed by mixing benzaldehyde‐ and cyanoacetate‐functionalized dextran with silver nitrate (AgNO3) and SA, enabling the ultrafast solidification and in situ self‐mineralization of silver ...

Fluidization Characteristics of a Centrifugal Fluidized Bed.
KAGAKU KOGAKU RONBUNSHU, 1993 遠心流動層は高ガス速度で運転でき, 微小粒子にも適用できるなど特長があるが, 層高が比較的低いためにガスの吹き抜けや部分的な流動化が起こりやすい.ここでは遠心流動層における流動化状態を, 流動化部と非流動化部に分けた部分流動化モデルを用いて, 理論的に検討し, 分散板に仕切を設け, 面積, 仕込量, 回転速度を変えて行った実験と比較した.その結果, ガス速度を変化させたときの圧力損失プロファイルの理論値と実験値が良好に一致した.これより, 遠心流動層では一部から流動化が始まり, 層全体に拡がる過程が説明できた.また, ガス流速による固定層割合の変化は, 部分流動化モデルで説明できた.この流動化状態の変化には, 粒子径や粉体物性の差が大きく影響することが判明した ...

Advanced Science, EarlyView.A sprayable near‐infrared‐activated nanoplatform incorporating MXene, ZnHCF nanozyme, and deferoxamine efficiently breaks the vicious cycle of diabetic wounds. Upon irradiation, interfacial electron transfer and photothermal effects enhance multi‐enzyme activity, enabling explosive ROS elimination, alleviation of hypoxia, and controlled DFO release ...

Advanced Science, EarlyView.Fully programmable, in‐process 3D magnetization integrated with multi‐material printing enables soft magnetic systems with precise actuation and sensing. Discrete and continuous magnetization profiles drive bending, morphing, and locomotion, demonstrated through strain‐sensing elements, dragonfly‐inspired wings, octopus‐like tentacles, and a serpentine

Advanced Science, EarlyView.Chronic stress disrupts copper homeostasis and promotes copper accumulation in the prelimbic cortex, leading to astrocytic FDX1 upregulation. Elevated astrocytic FDX1 impairs calcium signaling, induces structural atrophy, and disrupts synaptic function, contributing to depressive‐like behaviors. Physical exercise reverses these alterations by restoring
