Piperazine‐Functionalized Nanoparticles Enable Oral Insulin Delivery in Obese Mice

Advanced Science, EarlyView.
ABSTRACT Biologics have gained prominence as a rapidly advancing therapeutic modality for a diverse spectrum of medical conditions. Nonetheless, they are predominantly administered parenterally due to poor absorption through the gastrointestinal tract. Additionally, repeated injections of biologics such as insulin cause injection pain, leading to dose ...

A Three-Dimensional Turbulent Heat Transfer Analysis for Advanced Tubular Rocket Thrust Chambers [PDF]

Heat transfer was analyzed in the throat region of a plug and spool rocket engine for both smooth and corrugated walls. A three-dimensional, Navier-Strokes code was used for the analysis. The turbulence model in the code was modified to handle turbulence

Nano-scale displacement sensing based on Van der Waals interaction

, 2014
We propose the nano-scale displacement sensor with high resolution for weak-force systems could be realized based on vertical stacked two-dimensional (2D) atomic corrugated layer materials bound through Van der Waals (VdW) interaction.

Cascade‐Responsive MXene@Cu‐MOF Heterostructure Integrates Antioxidant Activity, Infection Control, and Vascularization for Tracheal Repair

Advanced Science, EarlyView.
A cascade‐responsive MXene@Cu‐MOF/GelMA hydrogel is engineered as a “skeleton–backpack” platform for extensive tracheal repair. The MXene framework scavenges postoperative ROS and converts NIR light into mild hyperthermia, while the Cu‐MOF component provides pH/NIR‐responsive Cu2+ dosing for infection control, angiogenesis, and chondrogenesis.

Thermal performance comparison of various corrugated channels using nanofluid: Numerical study

Alexandria Engineering Journal, 2019
A numerical simulation is performed on thermal performance comparison of a corrugated channel with three corrugation profiles. Semicircle, trapezoidal, and house shapes are considered as corrugation profiles for corrugated walls of channel using ...

Ropelength of tight polygonal knots

, 2004
A physical interpretation of the rope simulated by the SONO algorithm is presented. Properties of the tight polygonal knots delivered by the algorithm are analyzed. An algorithm for bounding the ropelength of a smooth inscribed knot is shown. Two ways of

Wavy‐Interlocked Stretchable Triboelectric Nanogenerators Enhanced by Liquid Metal Microflowers for Self‐Powered Wearable Motion Monitoring

Advanced Science, EarlyView.
Schematic showing a stretchable triboelectric nanogenerator based on interlocked wavy architectures that uses EGaIn microflower‐embedded PVDF‐TrFE and Nylon‐6 nanofiber membranes. The multi‐petaled, electron‐rich EGaIn microflowers enhance interfacial polarization and capacitance, while the interlocked wavy architecture enlarges the effective contact ...

Design aspects of steel I-girders with corrugated steel webs

Electronic Journal of Structural Engineering, 2007
Corrugated web girders represent a new structural system emerged in the past two decades. The girder’s flanges provide the flexural strength of the girder with no contribution from the corrugated web which provides the girder’s shear capacity.
