Recentment, el laboratori d’Electrònica Impresa de l’Institut de Microelectrònica de Barcelona (IMB-CNM) s'ha integrat a la ICTS distribuïda MicroNanoFabs, de la qual forma part la Sala Blanca de Micro i Nano Fabricació.
Més de 250 contribucions a la 18a Conferència Europea sobre Termoelectricitat organitzada a Barcelona per l'IMB-CNM
L'IMB-CNM (CSIC) ha coorganitzat, juntament amb IREC i AEInnova, el primer congrés internacional sobre termoelectricitat que se celebra de manera presencial des de l'inici de la pandèmia el 2020.
The natural environment has always been a source of inspiration for the research community. Nature has evolved over thousands of years to create the most complex living systems, with the ability to leverage inner and outside energetic interactions in the most efficient way. This work presents a flow battery profoundly inspired by nature, which mimics the fluid transport in plants to generate electric power. The battery was ecodesigned to meet a life cycle for precision agriculture (PA) applications; from raw material selection to disposability considerations, the battery is conceived to minimize its environmental impact while meeting PA power requirements.
Current advances in materials science have demonstrated that extracellular mechanical cues can define cell function and cell fate. However, a fundamental understanding of the manner in which intracellular mechanical cues affect cell mechanics remains elusive. How intracellular mechanical hindrance, reinforcement, and supports interfere with the cell cycle and promote cell death is described here. Reproducible devices with highly controlled size, shape, and with a broad range of stiffness are internalized in HeLa cells. Once inside, they induce characteristic cell-cycle deviations and promote cell death. Device shape and stiffness are the dominant determinants of mechanical impairment. Device structural support to the cell membrane and centering during mitosis maximize their effects, preventing spindle centering, and correct chromosome alignment. Nanodevices reveal that the spindle generates forces larger than 114 nN which overcomes intracellular confinement by relocating the device to a less damaging position. By using intracellular mechanical drugs, this work provides a foundation to defining the role of intracellular constraints on cell function and fate, with relevance to fundamental cell mechanics and nanomedicine.
