Recycling‐Induced Changes of Molecular Weight and Structural Properties in PET Monopolymer Blends

open access: yesJournal of Polymer Science, EarlyView.
The present study investigates the molecular weight, thermal, rheological, and mechanical properties of polymer blends of high and low molecular weight polyethylene terephthalate (PET) components. The research reveals that extrusion processing influences chain scission and chain extension, inhibiting the broadening of the molecular weight distribution ...

Electron Transfer Dissociation and Synchrotron UV Photodissociation of Trapped Sodiated Ions Produced From Polyacrylates by Electrospray Ionization

open access: yesRapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Poly (acrylates)s can be distinguished from one another by the nature of their side chains. From model poly (acrylates)s, the purpose of this work was to evaluate the contribution of alternative activation techniques to the collisional activation, based on ion–ion and ion–photon interactions.

Memristors Based on Ferroelectric Cu‐Deficient Copper Indium Thiophosphate for Multilevel Storage and Neuromorphic Computing

open access: yesSmall, EarlyView.
Different from CIPS with threshold switching behaviors, Cu‐deficient CIPS* shows stable non‐volatile digital and analog RS. Owing to the formation of metallic IPS at the LRS, CIPS* memristors demonstrate high ON/OFF ratio and endurance stability, which can be utilized to implement multilevel storage.

Laser‐Direct Printed 2D Material‐Based Heterostructure for the Fabrication of Electronic Devices

open access: yesSmall, EarlyView.
The Digital Laser‐Induced Forward Transfer (LIFT) approach is employed to pattern and stack 2D materials with micrometer‐scale precision. PdSe2 and MoSe2 are assembled into vertical p–n junctions, with graphene serving as a transparent electrode. The resulting laser‐transferred heterostructures exhibit high material quality and stable rectifying ...
