A new technique enables the use of, for example, cooking oil from fast-food restaurants to dissolve and separate silver. The process requires light and diluted hydrogen peroxide. The technique makes it possible to secure the supply of silver and reduce the burden on the environment.

A research team from Kumamoto University has developed a promising deep learning model that significantly enhances the accuracy of subgraph matching — a critical task in fields ranging from drug discovery to natural language processing.

    Led by Assistant Professor Kou Li, a research group in Chuo University, Japan, has developed an all-printable device fabrication strategy to resolve the existing technical limitations of multi-functional image sensor sheets for non-destructive inspections, with a recent paper publication in npj Flexible Electronics.

　While photo-thermoelectric (PTE) sensors and their ultrabroadband monitoring facilitate non-destructive testing, their conventional fabrication is insufficient for high-yield integration. Specifically, PTE devices faced challenges in their crucial spatial-misalignment for separate fabrication processes per constituent. Herein, this work demonstrates mechanically alignable and all-dispenser-printable integration of carbon nanotube (CNT) functional PTE sensor devices by designing them with solution-processable ink-materials. This technique first accurately prints CNT channels, essential in PTE conversion, using higher-concentration inks, and integrates remaining constituents (dopants and conductive pastes) into single device structures at high-yield. This work further demonstrates that employing higher-concentration CNT inks, suitable for mechanical channel printing, also designs sensitive PTE sensors. These sensors serve stably as integrated devices on diverse functional substrates, facilitating ubiquitous non-destructive monitoring depending on features. Therefore, this work designs such CNT PTE integrated devices and the associated functional inspection appropriately for structures, sizes, and external environments (e.g., temperature and humidity) of monitoring targets.

As kids spend more time on screens, a new national survey conducted by Ipsos on behalf of The Kids Mental Health Foundation, founded by Nationwide Children’s Hospital, identifies parents’ greatest fears for their children around screen time.

A joint research team from the Institute of Biophysics of the Chinese Academy of Sciences and the Beijing Institute of Technology has uncovered a pivotal mechanism by which bacteria defend themselves against viral infection.

USC Dornsife scientists have developed tools that can now interrupt specific links between neurons, called synapses, enabling targeted study of brain circuits. The method targets either excitatory or inhibitory synapses with molecular precision, leaving the rest of the neuron unharmed. The process is reversible, allowing researchers to study how specific circuits influence behavior, perception and neurological disorders. The technology could one day help guide therapies for conditions such as epilepsy, PTSD and addiction.
