Highly Sensitive Low-Frequency Acoustic Sensor Based on Functionalized Graphene Oxide.

Developing miniaturized low-frequency acoustic sensors with high sensitivity is crucial for diverse applications, including geological monitoring and aerospace exploration. However, the performance of low-frequency acoustic sensor is constrained by the limited mechanical robustness of traditional sensing films at nanoscale thickness. Here, a functionalized graphene oxide (GO)-based Fabry-Perot (FP) low-frequency sensor is proposed, with characteristics of compact size, resistance to electromagnetic interference high-sensitivity low minimum detectable pressure (MDP), and a high signal-to-noise ratio (SNR).

Unveiling the crucial role of iron oxide transformation in simultaneous immobilization of nanoplastics and organic matter.

Nanoplastics (NPs) have been found in natural environments. However, the sequestration of NPs and natural organic matter (NOM) coupled with the Fe(III) hydrolysis and subsequent iron oxides transformation remains unclear. Here, we investigated the behaviors of NPs during the dynamic transformation process of iron oxides in the presence of humic acids (HA).

Electrochemical Synthesis of Zeolite Coatings with Controlled Crystal Polymorphism and Self-Regulating Growth.

Zeolite coatings are studied as molecular sieves for membrane separation, membrane reactors, and chemical sensor applications. They are also studied as anticorrosive films for metals and alloys, antimicrobial and hydrophobic films for heating, ventilation, and air conditioning, and dielectrics for semiconductor applications. Zeolite coatings are synthesized by hydrothermal, ionothermal, and dry-gel conversion approaches, which require high process temperatures and lengthy times (ranging from hours to days).

Singlets-Driven Photoredox Catalysts: Transforming Noncatalytic Red Fluorophores to Efficient Catalysts.

Red-light absorbing photoredox catalysts offer potential advantages for large-scale reactions, expanding the range of usable substrates and facilitating bio-orthogonal applications. While many red-light absorbing/emitting fluorophores have been developed recently, functional red-light absorbing photoredox catalysts are scarce. Many photoredox catalysts rely on long-lived triplet excited states (triplets), which can efficiently engage in single electron transfer (SET) reactions with substrates.

The effect of right versus left long-term single-sided deafness on sound source localization.

Purpose: To analyze the effect of right versus left long-term single-sided deafness (SSD) on sound source localization (SSL), discuss the necessity of intervention and treatment for SSD patients, and analyze the therapeutic effect of long-term unilateral cochlear implantation (UCI) from the perspective of SSL.

Methods: This study included 25 patients with SSD, 11 patients with UCI, and 30 participants with normal hearing (NH). Their SSL ability was tested by obtaining their average root mean square (RMS) error values of SSL test.
