Acid drainage resulting from mining operations has led to significant iron contamination in surface waters, posing serious ecological and public health hazards. Elevated iron levels in freshwater ecosystems can severely affect aquatic organisms and human health. However, there remains a considerable...

Cellular senescence is strongly tied to vascular disease. The current study aims to examine ways that endothelial cellular senescence can be prevented and the mechanisms by which prevention of senescence occurs. Human umbilical vein endothelial cells were exposed to TNF-α to induce senescence; then...

With the domestic trend of value chains becoming increasingly apparent, innovation-driven growth is crucial for a higher position in various industries. This study analyzes the effect of building national laboratories on the national value chains’ position (the average propagation length) by employi...

With carbon neutrality as a target and the increased penetration of renewable energy, the operational flexibility of power systems has begun to face challenges. In order to explicitly represent the operational flexibility of power systems, two types of flexibility indexes and corresponding models fo...

Graphene oxide (GO) films have attracted significant attention due to their potential in separation and filtration applications. Based on their unique lamellar structure and ultrathin nature, GO films are difficult to maintain in a free-standing form and typically require substrate support. Conseque...

Temperature polarization is a critical factor influencing the performance of membrane distillation. The presence of temperature polarization causes the temperature of the fluid near the membrane surface to be different from that in the bulk region, reducing the effective temperature difference acros...

A two-mode (de)multiplexer [(DE)MUX] based on a multimode interferometer coupler and a symmetric Y-junction coupler is proposed and demonstrated on an InP substrate. By introducing a phase shifter section with a thickness-detuned core layer, a miniature two-mode (DE)MUX with mode conversion of 100&a...

Accumulation of advanced glycation end products (AGEs) and endothelial dysfunction are major factors that contribute to the progression of vascular complications in diabetes. Migrasomes, a newly discovered organelle involved in mitocytosis, play an important role in the selective removal of damaged...

In this work, HNTs@ZIF-67 composites were synthesized using the in situ growth method and incorporated into 6FDA-TFMB to prepare mixed-matrix membranes (MMMs). Scanning electron microscope (SEM) and transmission electron microscope (TEM) proved that the HNTs@ZIF-67 composite not only retained the ho...

We report the fabrication of a first electro-absorption modulated widely tunable DBR lasers (TEML) based on InGaAlAs multi-quantum well (MQW) material, which is superior than InGaAsP MQWs for the fabrication of both modulators and lasers. The device is fabricated by using butt-joint material growth...

Crop root system plays an important role in the water cycle of the soil-plant-atmosphere continuum. In this study, combined isotope techniques, root length density and root cell activity analysis were used to investigate the root water uptake mechanisms of winter wheat (Triticum aestivum L.) under d...

Mechanism of discontinuous precipitation (DP) in AZ80 alloy was investigated by phase-orientation correlated characterization. The results show DPs nucleate by turning the original grain boundaries (GBs) as reaction front (RF), and further driving the RF to realize their growth. The DPs regions reta...

Abstract CD70, which is a ligand belonging to tumour necrosis factors, exhibits aberrant overexpression among multiple hematologic and solid malignancies and has drawn extensive research enthusiasm as a target to treat and diagnose cancers. CD70‐targeted immuno‐PET/CT is an emerging approach for can...

Tea is one of the most popular non-alcoholic beverages in the world, and free amino acids, especially theanine, make a major contribution to the umami taste of tea. However, the genetic basis of the variation in amino acid content in tea plants remains largely unknown. Here, we measured the free ami...

Citrus fruits are rich in carotenoids. In the carotenoid biosynthetic pathway, lycopene β-cyclase (LCYb, EC:1.14.-.-) is a key regulatory enzyme in the catalysis of lycopene to β-carotene, an important dietary precursor of vitamin A for human nutrition. Two closely related lycopene β-cyclase cDNAs,...
