Researchers have successfully synthesized a new material that exhibits self-recoverable near-infrared (NIR) mechanoluminescence, a property useful for biomedical imaging and other applications. The material's mechanism is attributed to its piezoelectricity, which generates excited states in Cr³⁺ ions upon mechanical stimulation.
Researchers propose an indirect optical method for determining internal temperatures of opaque packed beds based on phosphor thermometry. Ray tracing simulations enable simultaneous multi-point measurements, allowing for accurate full temperature distribution within the bed.
A large-scale study found exposure to low and high biothermal stress during pregnancy linked to a higher risk of babies being born too small or large for their gestational ages. The study also identified specific subpopulations at higher risk, including non-Caucasian people and those aged 35 and above.
A pioneering study using mobile phone data analysis sheds light on socioeconomic disparities in unhealthy food reliance during COVID-19, particularly among racial minorities and low-income households. The study found that COVID-19 has exacerbated convenience store reliance, especially in Hispanic-majority counties and areas with older ...
A new AI system developed by the University of Technology Sydney can rapidly detect COVID-19 from chest X-rays with high accuracy. The Custom Convolutional Neural Network (Custom-CNN) model streamlines the detection process, providing a faster and more accurate diagnosis.
Researchers developed a high-resolution cell type deconvolution mode method using CIBERSORTx to analyze pooled skin bulk transcriptome data, identifying eight different skin cell types. This allowed for more accurate analysis of gene expression changes post-burn injury and exploration of new targets for clinical wound healing.
Researchers uncover evidence of German soldiers consolidating the crater and using it to their advantage as a new defensive position. The detonation of the mine at Hawthorn Ridge marked the beginning of the Battle of the Somme, but alerted the Germans, leading to heavy losses among British troops.
Researchers developed a nanoenzyme called PCMF that responds to the tumor microenvironment, providing enhanced imaging contrast and inducing apoptosis in cancer cells. PCMF also exhibits photothermal conversion capability for combined therapy.
The study found that black spots in salmon fillets contain eumelanin, a type of melanin present in human hair and skin, while red spots do not detectably contain melanin. The discovery provides an important step towards understanding the cause of these unsightly spots.
Researchers discovered that adding disodium maleate to the electrolyte of aqueous zinc-ion batteries can inhibit dendrite growth and improve cyclability. The study demonstrated ultralong cycling lifespans of over 3200 hours and high Coulomb efficiency, making this a promising strategy for achieving stable metal anodes.
Researchers have successfully optimized 2D semiconductors through substitutional doping, demonstrating enhanced B-exciton emission and broad spectral response in V-doped MoS2 monolayers. This work paves the way for future optoelectronic devices with improved performance.
Aya Kubota emphasizes the importance of engaging local residents in historical environment preservation and regeneration. This approach supports the preservation and utilization of 'Legacy of Catastrophe' and presents a valuable alternative to current urbanization methods.
