Advances and Perspectives in Graphene‐Based Quantum Dots Enabled Neuromorphic Devices

open access: yesAdvanced Science, EarlyView.
Graphene‐based QDs are zero‐dimensional carbon nanomaterials with pronounced quantum confinement and tunable electronic structures. Herein, we summarize their synthesis strategies and functionalization methods, and highlight their functional roles and operating mechanisms in devices, as well as recent advances in neuromorphic electronics. We anticipate

Robust and Thermally Stable Silicone Aerogels with Hyperconnected Network via Kinetically Optimized Hyperbranched Silane Precursors

open access: yesAdvanced Science, EarlyView.
Reactivity‐Programmed Assembly: A kinetic‐control strategy is reported for constructing hyperconnected silicone aerogels with a robust “thick‐neck” architecture. By exploiting the reactivity disparity of precursors, flexible segments are uniformly embedded within a rigid skeleton.

Kinetics of methyl methacrylate template polymerization. [PDF]

open access: yes, 1977
A polymerization is called a template- or replica polymerization, if this polymerization is carried out in the presence of chain molecules of pre-formed polymer (the template) and proceeds along or in the proxiumity of those template molecules.

Adhesion‐Driven Removal of Microplastics From Aquatic Systems by Using Microgel Glues

open access: yesAdvanced Science, EarlyView.
Soft polymeric microgels function as “glues” that aggregate diverse microplastics through multivalent adhesion, promoting their interfacial deposition and co‐precipitation for efficient removal from water. Remarkably, this approach remains effective even for nanoscale plastic particles as small as 50 nm.

Degradation of poly(methyl methacrylate) model compounds at constant elevated temperature studied via high resolution electrospray ionization mass spectrometry (ESI-MS)

open access: yes, 2007
The products of the thermal degradation at 95°C over 10 months of ω-saturated and non-saturated poly(methyl methacrylate) (pMMA) model compounds were identified with high accuracy via quadrupole ion trap and quadrupole ion trap-time of flight (Q-ToF ...
