With that in mind, there’s the fact that a very warm fall has meant that instead of this garden looking near collapse, it’s going strong and the four billowing pots of herbs that remain are pressuring me to do something great with them before they meet their imminent frosty demise. Fried sage leaves on everything! Crisp rosemary flatbread all the time! Minced chives on every dish! Parsley… I mean, I like tabbouleh and all, but there’s no way I’m going to get through this. Let’s not pretend this made a huge dent, but 5 sprigs down is a respectable effort, right?
Flexible fiber-shaped supercapacitors have shown great potential in portable and wearable electronics. However, small specific capacitance and low operating voltage limit the practical application of fiber-shaped supercapacitors in high energy density devices. Herein, direct growth of ultrathin MnO2 nanosheet arrays on conductive carbon fibers with robust adhesion is exhibited, which exhibit a high specific capacitance of 634.5 F g−1 at a current density of 2.5 A g−1 and possess superior cycle stability. When MnO2 nanosheet arrays on carbon fibers and graphene on carbon fibers are used as a positive electrode and a negative electrode, respectively, in an all-solid-state asymmetric supercapacitor (ASC), the ASC displays a high specific capacitance of 87.1 F g−1 and an exceptional energy density of 27.2 Wh kg−1. In addition, its capacitance retention reaches 95.2% over 3000 cycles, representing the excellent cyclic ability. The flexibility and mechanical stability of these ASCs are highlighted by the negligible degradation of their electrochemical performance even under severely bending states. Impressively, as-prepared fiber-shaped ASCs could successfully power a photodetector based on CdS nanowires without applying any external bias voltage. The excellent performance of all-solid-state ASCs opens up new opportunity for development of wearable and self-powered nanodevices in near future.
Wearable, fiber-shaped, and all-solid-state asymmetric supercapacitors (ASCs) have been successfully constructed with a maximum operating voltage of 1.5 V using ultrathin MnO2 nanosheets and graphene on carbon fibers as positive and negative electrode, respectively. The fabricated fiber-shaped ASCs display excellent bendability and mechanical stability, and possess enough energy to power a CdS nanowire photodetector without applying any external bias voltage.

Direct access to complex, enantiopure benzylamine architectures using a synergistic iridium photoredox/nickel cross-coupling dual catalysis strategy has been developed. New C(sp3)C(sp2) bonds are forged starting from abundant and inexpensive natural amino acids.
Making light of it: A novel dual catalytic route to enantiopure benzylic amines is outlined, and it takes advantage of photoredox catalysis in conjunction with nickel-catalyzed cross-coupling. The starting materials are robust organotrifluoroborates that can engage, with an expanded range of densely functionalized aryl- and heteroaryl halides, in the title reaction.
This strip was definitely influenced by the only nude beach I've been to, on one of the small cities of Cinque Terra with my friend-for-ife Val (who, incidentally, influenced Jamie and her relationship with Hazel a bit as well).

I hate the art in this one, I couldn't even bring myself to shade the fucking thing but oh well whatever
