Compression-Durable Soft Electronic Circuits Enabled by Embedding Self-Healing Biphasic Liquid-Solid Metal Into Microstructured Elastomeric Channels.

Compression strongly degrades the electrical conductivity of the liquid-metal-based circuits because the liquid state is prone to be squashed. Here, a new compressible and stretchable biphasic liquid-solid self-healing circuit is proposed by filling GalnSn-BilnSn biphasic metal into micropillar-embedded channels. The underlying BilnSn solid alloy layer serves as a compression resistance layer, while the upper GalnSn liquid metal layer enables the real-time filling of the cracks in the solid layer under large deformations, resulting in autonomous self-healing and maintenance of conductivity under both stretching and compression.

Cordycepin, a natural adenosine derivative, exhibits multiple pharmacological effects on organisms. However, its distribution and metabolic characteristics have not been fully elucidated in vivo. In this study, ultra-high liquid chromatography tandem high-resolution mass spectrometry (UHPLC-HRMS/MS) was used to investigate the pharmacokinetic characteristics and effects of cordycepin on endogenous adenosine and inosine.

Background And Objectives: Reflex syncope (RS) is the most common type of syncope caused by dysregulation of the autonomic nervous system. Diagnosing RS typically involves the head-up tilt test (HUTT), which tracks physiological signals such as blood pressure and electrocardiograms during postural changes. However, the HUTT is time-consuming and may trigger RS symptoms in patients.

Instituto de Ciencias Físicas, Universidad Nacional Autónoma de México, 62210 Cuernavaca, Mexico. Electronic address:
Airborne acoustic levitation has seen great advances in recent years largely due to the development of devices utilizing arrays of compact, low-power, piezoelectric transducers. In particular, standing wave acoustic levitators are acoustic cavities, consisting of either a single piezoelectric boundary opposing a reflector or two opposing piezoelectric boundaries operating simultaneously. The multiple intra-cavity reflections can be significant enough to generate voltages and currents at the electrical port due to the direct piezoelectric effect, providing valuable information about the optimal operating conditions of the cavity.
