Optical Evidence of Interfacial Strain-Induced Ferroelectric Tuning and Enhancement in CuInPS via Ferroelectric Substrate.

The precise domain control in ferroelectric CuInPS (CIPS) remains challenging. A promising approach is by interfacing CIPS with the ferroelectric layer, but interface-driven ferroelectricity tunning mechanism remains unclear. Here, the demonstration of interfacial strain-induced ferroelectric tuning and enhancement in CIPS via ferroelectric substrate is reported by photoluminescence (PL) spectroscopy, combined with piezoresponse force microscopy (PFM) and density functional theory (DFT) calculations.

Plasma-induced Fe-doped zeolitic imidazolate framework-8 derived P-Fe-NC for enhanced phenol degradation.

Plasma-synergistic catalysis is considered an effective method for degrading aromatic organic pollutants in water. However, the underlying synergistic catalytic mechanism between plasma and catalysts remains poorly understood. Here, we propose a plasma-metal organic frameworks (MOFs) synergistic strategy to investigate the mechanism of plasma-synergistic catalysts for phenol degradation.

MXene Manipulating the Electronic and Photoelectric Properties of a Fullerene-Layered Heterojunction.

An in-depth study of the substrate effect is crucial for optimizing and designing the performance of two-dimensional (2D) materials in practical applications. Fullerene monolayers (FMs), a new pure carbon system successfully prepared recently, have prompted renewed interest in the question of whether FMs might be exploited to create carbon-based functional materials with improved performance. Here, the electronic structure of a MXene-supported FM was investigated by first-principles calculations.

Strain-tunable electronic anisotropy of the AlSb double-layer honeycomb structure.

Two-dimensional (2D) materials show promising applications in nanoelectronic devices due to their excellent physical and chemical properties, large specific surface area, and good flexibility. 2D AlSb, a representative of a new class of two-dimensional materials with a double-layer honeycomb (DLHC) structure was recently obtained in experiments and was reported to be a direct band gap semiconductor. Strain engineering is an effective way of tuning the properties of 2D materials.

Hydrometeorological conditions drive long-term changes in the spatial distribution of in a subtropical lake.

Globally, anthropogenic disturbance and climate change caused a rapid decline of submerged macrophytes in lake ecosystems. (), a species that germinates in winter, explosively expanded throughout many Chinese lakes, yet the underlying mechanism remained unclear. Here, this study examined the long-term changes in the distribution patterns of in Lake Gaoyou by combining remote sensing images and hydrometeorological data from 1984 to 2022 and water quality data from 2009 to 2022.

Analysis of alpha-1-antitrypsin (AAT)-regulated, glucocorticoid receptor-dependent genes in macrophages reveals a novel host defense function of AAT.

Alpha-1-antitrypsin (AAT) plays a homeostatic role in attenuating excessive inflammation and augmenting host defense against microbes. We demonstrated previously that AAT binds to the glucocorticoid receptor (GR) resulting in significant anti-inflammatory and antimycobacterial consequences in macrophages. Our current investigation aims to uncover AAT-regulated genes that rely on GR in macrophages.

Copper as an Electron Hunter for Enhancing BiOCO Electrocatalytic CO Conversion to Formate.

Cu-doped BiOCO catalyst with copper (Cu) acting an electron hunter for conversion of carbon dioxide into formate is developed. The Cu-BiOCO catalyst with hollow microsphere structure extends the duration of CO retention on the catalyst, providing a greater number of active sites. It exhibits remarkable performance with conversion efficacy of 98.

How sediment dredging alters phosphorus dynamics in a lowland rural river?

China's lowland rural rivers are facing severe eutrophication problems due to excessive phosphorus (P) from anthropogenic activities. However, quantifying P dynamics in a lowland rural river is challenging due to its complex interaction with surrounding areas. A P dynamic model (River-P) was specifically designed for lowland rural rivers to address this challenge.

Identification of Methamphetamine Abusers Can Be Supported by EEG-Based Wavelet Transform and BiLSTM Networks.

Methamphetamine (MA) is a neurological drug, which is harmful to the overall brain cognitive function when abused. Based on this property of MA, people can be divided into those with MA abuse and healthy people. However, few studies to date have investigated automatic detection of MA abusers based on the neural activity.

Shifts of the pond area ratio for lowland polders: Implication for nutrient control.

Shifts for natural ecosystems were increasingly concerned due to its profound impacts on ecosystem services. Ponds within lowland artificial watersheds (polders) play a critical role in nitrogen (N) and phosphorus (P) cycling. From the perspective of N & P control in management practices, it is needed to determine an optimal pond area ratio for polders.

Lycopene Promotes Osteogenesis and Reduces Adipogenesis through Regulating FoxO1/PPARγ Signaling in Ovariectomized Rats and Bone Marrow Mesenchymal Stem Cells.

Recent interest in preventing the development of osteoporosis has focused on the regulation of redox homeostasis. However, the action of lycopene (LYC), a strong natural antioxidant compound, on osteoporotic bone loss remains largely unknown. Here, we show that oral administration of LYC to OVX rats for 12 weeks reduced body weight gain, improved lipid metabolism, and preserved bone quality.
