Multifunctional Microstructured Surfaces by Microcontact Printing of Reactive Microgels

Advanced Functional Materials, EarlyView.
Reactive poly(N‐vinylcaprolactam‐co‐glycidyl methacrylate) microgels are used as functional inks to create surface‐grafted arrays on glass via microcontact printing. The patterns (10–50 µm widths and spacings) enable stable binding and post‐functionalization with dyes and peptides.

Locally Linearized Solution of Lifting Transonic Flow by Method of Parametric Differentiation

Journal of Mathematical and Fundamental Sciences, 2019
The governing equation of transonic small disturbance flow present a non-linear partial differential equation which is difficult to solve. The method of parametric differentiation reduces the non-linear partial differential equation of transonic flow ...

Solution of steady and unsteady transonic-vortex flows using Euler and full-potential equations [PDF]

Two methods are presented for inviscid transonic flows: unsteady Euler equations in a rotating frame of reference for transonic-vortex flows and integral solution of full-potential equation with and without embedded Euler domains for transonic airfoil ...

Room‐Temperature, High‐Resolution Soft Anisotropic Conductive Film for Electrical Interfacing in Stretchable Electronics

Advanced Functional Materials, EarlyView.
A UV‐crosslinkable soft anisotropic conductive film (ACF) provides high‐resolution, room‐temperature electrical interfacing. Upon UV exposure, azide crosslinkers within the ACF matrix form covalent bonds with a wide range of C–H‐containing materials, resulting in interfaces that are both mechanically durable and electrically reliable.

Unsteady Aerodynamics of Continuously Morphing Airfoils from Transonic to Hypersonic Regimes

Aerospace
Designing high-speed aircraft for wide-speed-range operation remains a major aerodynamic challenge. This study investigates the unsteady aerodynamics of a continuously morphing airfoil from transonic to hypersonic regimes. A smooth morphing trajectory is

Prediction of transonic flutter for a supercritical wing by modified strip analysis and comparison with experiment [PDF]

Use of a supercritical airfoil can adversely affect wing flutter speeds in the transonic range. As adequate theories for three dimensional unsteady transonic flow are not yet available, the modified strip analysis was used to predict the transonic ...

Complementary Logic Driven by Dielectrophoretic Assembly of 2D Semiconductors

Advanced Functional Materials, EarlyView.
Scalable, parallel fabrication of complementary logic gates is demonstrated using electric‐field‐driven deterministic assembly of electrochemically exfoliated 2D n‐type MoS2 and p‐type WSe2 nanosheets. This strategy yields MoS2 and WSe2 transistors featuring average mobilities of 4.3 and 3.0 cm2 V−1 s−1, respectively, and on/off ratios of > 104 ...

Numerical calculation of transonic boattail flow [PDF]

A viscid-inviscid interaction procedure for the calculation of subsonic and transonic flow over a boattail was developed. This method couples a finite-difference inviscid analysis with an integral boundary-layer technique.

Stabilizing Cationic Palladium Single‐Atom Sites on Heteroatom‐Doped Carbon for Selective Hydrogen Peroxide Electrosynthesis

Advanced Functional Materials, EarlyView.
In this research, it is demonstrated that dual nitrogen and sulfur doping in hollow carbon spheres creates a tunable coordination environment that stabilizes cationic Pd single atoms as robust organometallic complexes, enabling high selectivity and stability for electrochemical hydrogen peroxide production under harsh acidic and peroxide‐rich ...

FORTRAN program for calculating velocities and streamlines on the hub-shroud mid-channel flow surface of an axial-or mixed-flow turbomachine. 2: Programmer's manual [PDF]

A FORTRAN-IV computer program, MERIDL, has been developed that obtains a subsonic or shock-free transonic flow solution on the hub-shroud mid-channel flow surface of a turbomachine.
