Advanced Materials, EarlyView.A novel dual‐modification approach, ─NH₂ groups modification and Cu ions coordination, is first imposed on MIL‐125, which greatly improved carrier separation due to the enhanced piezoelectricity of MOFs caused by polarity alteration, leading to exceptional high piezo‐photocatalytic hydrogen production.

Advanced Materials, EarlyView.Implantable devices rely on batteries that demand surgical replacement, posing risks, and financial burdens. Ultrasound energy transfer (US‐ET) offers a revolutionary wireless alternative but struggles with efficiency. The presented dielectric‐ferroelectric‐boosted US‐TENG (US‐TENGDF‐B) is thin, flexible, and biocompatible that provides high‐efficiency

Recursive Visual Sound Separation Using Minus-Plus Net [PDF]
arXiv, 2019 Sounds provide rich semantics, complementary to visual data, for many tasks. However, in practice, sounds from multiple sources are often mixed together. In this paper we propose a novel framework, referred to as MinusPlus Network (MP-Net), for the task of visual sound separation.

Advanced Materials, EarlyView.This study reports the discovery of a stable γ‐phase in Cu6Te3‐xS1+x, achieving high thermoelectric performance with a Seebeck coefficient up to 200 µVK⁻¹ and ultralow thermal conductivity (≈0.25 Wm⁻¹K⁻¹). The material eliminates phase transitions, exhibits a zT of ≈1.1 at 500 K, and offers a cost‐effective, eco‐friendly alternative for waste heat ...

Leveraging Moving Sound Source Trajectories for Universal Sound Separation [PDF]
arXivExisting methods utilizing spatial information for sound source separation require prior knowledge of the direction of arrival (DOA) of the source or utilize estimated but imprecise localization results, which impairs the separation performance, especially when the sound sources are moving.

Sound Event Detection Using Graph Laplacian Regularization Based on Event Co-occurrence [PDF]
arXiv, 2019 The types of sound events that occur in a situation are limited, and some sound events are likely to co-occur; for instance, ``dishes'' and ``glass jingling.'' In this paper, we propose a technique of sound event detection utilizing graph Laplacian regularization taking the sound event co-occurrence into account.
