Monolithic 3D‐Integrated All‐Solid Ion‐Gated Carbon Nanotube Transistors With Tunable Ionic Conductance for Multi‐Timescale Reservoir Computing

Advanced Materials, EarlyView.
A dual‐timescale reservoir based on monolithically 3D (M3D)‐integrated CNT solid ion‐gated transistors is demonstrated. Tunable ionic dynamics and pulse‐engineered operation enable linear and symmetric synaptic updates. The M3D‐integrated array achieves robust temporal encoding and accurate classification of moving MNIST sequences, highlighting its ...

Film cooling characteristics of squealer tip of a turbine blade

Xibei Gongye Daxue Xuebao
The high-speed and high-temperature gap leakage flow in the turbine blade tip clearance directly scours the tip of the rotor blade and generates a local high-temperature region, so the active and passive control of the gap leakage flow is very important.

Effect of Calcium Addition Amount and Soft Argon Blowing on Inclusions in 316L Stainless Steel

Teshugang, 2022
316L stainless steel is prepared by the production process of 20 t EAF-AOD-LF-casting ingots, and the inclusion content in steel is reduced by LF calcium treatment and bottom argon blowing.

A Geometrically Transient Platform for Bioelectronic Implants

Advanced Materials, EarlyView.
Minimally invasive bioelectronic implants often compromise performance for smaller sizes. To resolve this optimization dilemma, a wireless bioelectronic implant with a transient geometry is introduced (MiFi). The origami‐inspired device miniaturizes up to sixfold for syringe insertion and autonomously unfolds post‐implantation.

Effects of blow molding ratio on mechanical properties of polylactide nanocomposite films

Polimery, 2010
The results of the investigations of the effect of blow-up ratio of nanocomposite poly(lactic acid) (PLA) films on the mechanical properties determined under static tension are discussed. Investigated films contain additives in the form of a montmorillonite (MMT) nanofiller (LC sample) or MMT and poly(methyl methacrylate) (PMMA) as a modifier (LCM ...

Beyond Nanoporosity: A CO2‐Conditioned Glassy Matrix Contributes to the Brittle‐to‐Ductile Transition of Nanocellular Polyetherimide

Advanced Materials, EarlyView.
The mechanical performance of nanocellular polyetherimide cannot be explained by nanoporosity alone. It is shown that CO2 saturation and desorption leave a distinct mechanical signature in the glassy matrix before foaming. This matrix contribution provides a new route to understand and optimize the brittle to ductile transition in nanocellular polymers.

Aerothermal Characteristics of Trailing Edge Region Film Cooling on a Nozzle Guide Vane [PDF]

Journal of Applied Fluid Mechanics
Maintaining the trailing edge of the first stage high-pressure nozzle guide vane (NGV) in high-temperature regions (̴ 2200K) is always a challenging task compared to the other locations.

Numerical simulation of blowing ratio effects on film cooling on a gas turbine blade [PDF]

WIT Transactions on Modelling and Simulation, 2011
This article investigates the film cooling effectiveness and heat transfer in three regimes for a film-cooled gas turbine blade at the leading edge of the blade with 45 0 angle of injection. A Rolls Royce blade has been used in this study as a solid body with the blade cross section from Hub to Shroud varying with a degree of skewness.

Multilayered Digital Microfluidic Chip for Cell‐Based Assays

Advanced Materials Interfaces, EarlyView.
A multilayered digital microfluidic (mDMF) chip architecture is introduced to improve throughput and robustness in cell‐based assays. By multilayering electrode components and dielectric layers on glass, this design significantly reduces actuation voltage, maintains reliability, and enables expansion of the operational area with minimum current leakage.
