Shielding weakening of high-velocity fluid against precipitation-static

Engineering Applications of Computational Fluid Mechanics
Recent experiments have demonstrated that high-density space charge around a structure can shield precipitation-static on the structure’s surface, while high-velocity fluid can weaken this shielding effect.

Stretching the Printability Metric in Direct‐Ink Writing with Highly Extensible Yield‐Stress Fluids

Advanced Functional Materials, EarlyView.
This study introduces “drawability” as a new metric for assessing printability in direct‐ink writing, focusing on gap‐spanning performance and speed robustness. By designing yield‐stress fluids with high extensibility, we demonstrate that extensional strain‐to‐break significantly enhances printability.

Wireless charging system for static electric vehicles

Enfoque UTE, 2019
El lento crecimiento del uso de vehículos eléctricos se debe a múltiples problemas, uno de ellos es la carga del auto utilizando cable, método conocido como plug-in. Una alternativa tecnológica que puede sustituir a los cables es el sistema de transferencia de energía mediante inducción electromagnética; por el momento esta transferencia de energía es ...

Fabrication of Alignment Layer of Liquid Crystal Display by Electron Beam Lithography

, 2007
在液晶顯示器工業中，傳統上液晶的配向是以摩擦配向的方法完成的。雖然這種傳統的方法十分簡單及方便，但是會有靜電殘留以及灰塵粒子污染的問題，且這種方法的機制尚未完全被人們明瞭。於1972年，Berreman提出配向的原因是因為在經過對表面的摩擦之後會產生極細微的溝槽結構，而液晶沿著溝槽結構做排列將會達到最低能量狀態。在本論文中，我們嘗試基於Berreman的理論模型以電子束微影蝕刻的方式製造極細微溝槽結構做為液晶顯示器配向層，這也可以避免傳統摩擦配向上所產生的問題 ...

All‐in‐One Analog AI Hardware: On‐Chip Training and Inference with Conductive‐Metal‐Oxide/HfOx ReRAM Devices

Advanced Functional Materials, EarlyView.
An all‐in‐one analog AI accelerator is presented, enabling on‐chip training, weight retention, and long‐term inference acceleration. It leverages a BEOL‐integrated CMO/HfOx ReRAM array with low‐voltage operation (<1.5 V), multi‐bit capability over 32 states, low programming noise (10 nS), and near‐ideal weight transfer.

Neural Network-Based Modeling of Electric Vehicle Energy Demand and All Electric Range

Energies, 2019
A deep neural network-based approach of energy demand modeling of electric vehicles (EV) is proposed in this paper. The model-based prediction of energy demand is based on driving cycle time series used as a model input, which is properly preprocessed ...

Printed Integrated Logic Circuits Based on Chitosan‐Gated Organic Transistors for Future Edible Systems

Advanced Functional Materials, EarlyView.
Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

Electric and dilatonic fields of a charged massive particle at rest in the field of a charged dilaton black hole

European Physical Journal C: Particles and Fields
We study linear-perturbation equations for the two-body system of a charged dilaton black hole, of which dilaton coupling constant is $$\alpha $$ α , and a static particle with mass m, electric charge q, and dilatonic charge $$\beta m$$ β m .

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

Advanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron
