In Situ Amidation‐Derived Interfacial Modulation for Homogeneous Ultra‐High Nanoparticle Loading Toward Robust and Flexible Piezoelectric Composites

Advanced Functional Materials, EarlyView.
Synergistic interfacial strategy between inorganic ceramic fillers and polymer chains effectively inhibit particle aggregation and interfacial incompatibility. complex covalent and non‐covalent interfacial interactions promote superior uniformity, ultra‐high ceramic filler loading, and strong grain‐to‐grain connectivity, thereby enabling the ...

ANALYSIS OF MECHANISM OF EXCITATION OF VIBRATIONS OF WORKING BODIES OF DISKATOR WITH ROTATION AROUND AXIS OF ATTACHMENT

Vibrations in engineering and technology, 2023
The paper proposes an analytical model of interaction with the ground of a spherical disk mounted on an elastic riser at angles to the direction of movement and vertical. The working hypothesis is that fluctuations in the elastic riser-disk system occur due to periodic changes in the components of the traction resistance.The model provides for the ...

Delivery of Multifunctional Microspheres via Intravesical Instillation for Bladder Carcinoma: Therapeutic Potential and Mechanistic Insights

Advanced Healthcare Materials, EarlyView.
PCTM microspheres were successfully synthesized using microfluidic and click chemistry techniques.In Vivo and in vitro experiments have shown that PCTM microspheres have obvious targeting, adhesion, membrane penetration and anti‐tumor properties for bladder tumors.The antitumor mechanism of PCTM microspheres is to indirectly induce S‐stage blockage of ...

Low‐Temperature Fabrication of Thymosin β4‐Loaded Soluble Microneedles to Promote Wound Healing by Specific Binding to Downregulated Immune Regulators Vsig4 and IL22rɑ2

Advanced Healthcare Materials, EarlyView.
Schematic diagram depicting the fabrication and application of thymosin β4 (Tβ4)‐loaded microneedle patches for wound treatment. The Tβ4 was loaded into chitosan (CS) and sucrose MNs under mild conditions (4°C, 65% relative humidity). The Tβ4 MN patch specifically binds to the downregulated immune regulators Vsig4 and IL22rα2, thereby accelerating ...

Electro-mechanical coupling of rotating 3D beams

MATEC Web of Conferences, 2016
A rotating thin-walled beam with piezoelectric element is analysed. The beam is considered to vibrate in space, hence the longitudinal, transverse and torsional deformations are taken into account.

Stability diagnosis of rotor-oil film bearing system by utilizing magnetic bearing

Nihon Kikai Gakkai ronbunshu, 2016
Oil film bearings are applied for large rotational machineries owing to their large load capacity and damping effect. However, a swirling flow of the lubricant induces self-excitation at high rotational speed.

3D‐Printed Gastrointestinal Stents: In Vivo Evaluation in a Swine Small Bowel Perforation Model

Advanced Healthcare Materials, EarlyView.
Gastrointestinal fistulae and perforations can lead to severe complications including sepsis and patient death. In this work, the efficacy of 3D‐printed gastrointestinal stents composed of poly‐lactic‐acid (PLA) was evaluated in an in vivo swine model.

Accurate one dimensional beam modeling method for a rotor shaft with stepped cross-sections in the finite element method

Nihon Kikai Gakkai ronbunshu, 2014
The bending stiffness at the stepped cross-section of a rotor decreases in accordance with the elasticity in the face of the cross-section. This study proposes a method to deal with this decrease in bending stiffness in one dimensional (1D) beam modeling.
