Phase‐Change Solvents for Thermally Switchable Ion Conduction in Organogels

open access: yesAdvanced Materials, EarlyView.
Organogels containing salts dissolved in phase‐change solvents exhibit thermally switchable ion conduction. The organogels, which display an over 10 000‐fold on‐off ratio and high cycling stability, can be synthesized with a wide range of salts and customizable conductivity/temperature relations for applications in ionotronics and energy storage ...

Ultra‐Sensitive Nanofiber‐Based Triboelectric Nanogenerator for Energy Harvesting and Self‐Powered Sensing

open access: yesAdvanced Materials, EarlyView.
A multidimensional molecular strategy optimizes the tribonegative layer by electrospinning PVDF‐HFP for dipole alignment and crystallinity, followed by 2D borophene doping to enhance conductivity and charge trapping. Integrated with Nylon‐66 nanofibers, the composite device delivers a record sensitivity of 53.8 ± 1.2 V kPa−1 at 3 Hz, enabling ultra ...

Le implicazioni politiche dell'identità di filosofia e scienza in Ugo Spirito [PDF]

open access: yes, 2000
Nel riferirmi all'identità di scienza e filosofia, pur proponendomi di coglierne le implicazioni politiche emerse nel corso degli anni Trenta, penso che si debba partire proprio dall'adesione iniziale ai princìpi dell'idealismo attuale ed al proposito ...

Light‐Controlled Exposure of Cancer Cells to Reactive Oxygen Species Using Organic Semiconductor Thin Films

open access: yesAdvanced Materials Interfaces, EarlyView.
Spin‐coated films of the conjugated polymer F8T2 (poly (9,9‐dioctylfluorene‐alt‐bithiophene)) generate superoxide at the film‐medium interface, enabling precise delivery of reactive oxygen species (ROS) as visible‐light “ROS patches.” Coated surfaces drive rapid, localised cytotoxicity in MCF7 cancer monolayers under white light, providing a reagent ...
