Cryogenic Neuromorphic Synaptic Behavior in 180 nm Silicon Transistors for Emerging Computing Systems

open access: yesAdvanced Intelligent Systems, EarlyView.
This study investigates the neuromorphic plasticity behavior of 180 nm bulk complementary metal oxide semiconductor (CMOS) transistors at cryogenic temperatures. The observed hysteresis data reveal a signature of synaptic behavior in CMOS transistors at 4 K.

Restoring Porosity and Uncovering Flexibility in Pillared 3D‐Linker Metal‐Organic Frameworks

open access: yesAngewandte Chemie, EarlyView.
This research explores new design approaches towards robust frameworks which retain structural flexibility and porosity after activation. By incorporating bulky 3D‐linkers as anionic pillars with zinc triazolate sheets, moisture‐stable metal‐organic frameworks (MOFs) are synthesized. In situ powder X‐ray diffraction and gas adsorption techniques reveal

Control of Tetrazine Bioorthogonal Reactivity by Rotaxanation

open access: yesAngewandte Chemie, EarlyView.
Control of tetrazine‐mediated inverse electron demand Diels–Alder (IEDDA) reaction has been achieved by rotaxanation. Tetrazine rotaxanes were synthesized in high yield and they displayed a much slower kinetics compared to the corresponding thread. Mechanical bond disassembly upon the right stimulus activates reactivity.

Sequence‐Specific Installation of Aryl Groups in RNA via DNA‐Catalyst Conjugates

open access: yesAngewandte Chemie, EarlyView.
DNA oligonucleotides carrying amine nucleophilic catalysts are employed to deliver aryl groups to complementary sites in RNA under physiological conditions. The strategy can be used to sequence‐specifically label protein‐coding RNAs, or to knock down expression selectively, with potential applications in basic transcriptome research and in future ...
