Single‐ and Dual‐Atom Configurations in Atomically Dispersed Catalysts for Lithium–Sulfur Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Single‐atom and dual‐atom‐based atomically dispersed catalysts (ADCs) effectively address the shuttle effect and sluggish redox kinetics in Li–S batteries. With nearly 100% atomic utilization and tunable coordination environments, ADCs enhance LiPSs adsorption, lower conversion barriers, and accelerate sulfur redox reactions.

Model predictive cascade control

open access: yes, 2003
In this thesis, a state space Model Predictive Control (MPC) algorithm for multirate cascade control is discussed in detail. An appropriate choice of the cost function is necessary to ensure zero steady state error of the closed loop system. In this thesis, the influence the estimation horizon has on the closed-loop disturbance rejection property and ...

Interfacial Modulation for High‐Efficiency Large‐Area Organic Photovoltaics and Perovskite‐Organic Tandem Solar Modules

open access: yesAdvanced Functional Materials, EarlyView.
Self‐assembled monolayers (SAMs) are promising hole‐transporting materials for organic photovoltaics (OPVs), but suffer from self‐aggregation and poor large‐area uniformity. We find that interfacial modification using nicotinic hydrazide can eliminate the residual SAM aggregates by forming energetically favorable complexes, yielding uniform SAM.

Approximation Algorithms for Cascading Prediction Models

open access: yes, 2018
We present an approximation algorithm that takes a pool of pre-trained models as input and produces from it a cascaded model with similar accuracy but lower average-case cost. Applied to state-of-the-art ImageNet classification models, this yields up to a 2x reduction in floating point multiplications, and up to a 6x reduction in average-case memory I ...

Dual Attention-Guided Self-Adaptive Aware Cascade Network for Multi-View Stereo and Stereo Matching

open access: yesIEEE Access
Extensive studies have been conducted on multi-view stereo and stereo matching for 3D reconstruction, whereas relatively few methods have been proposed for a large-scale environment. The difficulty of producing high-resolution depth/disparity maps is one

Unsteady Flow Field Predictions for Oscillating Cascades [PDF]

open access: yes, 1993
The unsteady flow field around an oscillating cascade of flat plates with zero stagger is investigated using a time-marching Euler code. This case has an exact solution based on linear theory and serves as a model problem to study pressure wave propagation in the numerical solution.

Atomic Layer Deposition in Transistors and Monolithic 3D Integration

open access: yesAdvanced Functional Materials, EarlyView.
Transistors are fundamental building blocks of modern electronics. This review summarizes recent progress in atomic layer deposition (ALD) for the synthesis of two‐dimensional (2D) metal oxides and transition‐metal dichalcogenides (TMDCs), with particular emphasis on their enabling role in monolithic three‐dimensional (M3D) integration for next ...

Multi‐Functional ZnO–Te Heterojunction Devices Enabling Compact Frequency Quadrupler

open access: yesAdvanced Functional Materials, EarlyView.
Wafer‐scale ZnO–Te heterojunction devices featuring tunable double negative differential transconductance (D‐NDT) are demonstrated at ≤ 200°C. Leveraging this unique characteristic, a single‐stage frequency quadrupler is realized, achieving a 64%–75% reduction in device count.
