Synthesis of hydrophilic isotactic polypropylenes promoted by metallocene catalysts [PDF]
, 2006 In this paper, the synthesis of isotactic polypropylenes (i-PP) modified with [BOND]OH groups in sides (iPP-OH), by combination of polyinsertion ansa-metallocene catalysis and ring opening of propene oxide (PO), is described.

Advanced Functional Materials, EarlyView.A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

Influences of impurities in recycled plastics on properties of PIM sandwich panels [PDF]
, 2009 Powder impression moulding (PIM) is a novel technology for manufacturing lightweight sandwich panels from plastics in powder form. The process is featured by its high tolerant to impurities or contaminants in the feedstock and thus requires much less ...

Binary‐to‐Ternary Reconfigurable Transistors Using Plasma‐Assisted MoS2
Advanced Functional Materials, EarlyView.A binary‐to‐ternary reconfigurable transistor is demonstrated using a dual‐gated molybdenum disulfide homojunction with localized O2 plasma treatment. The device exhibits on/intermediate and intermediate/off current ratios of 102 and 104, respectively, and the intermediate state is electrically tunable in the ternary mode.

Synthesis and applications of functionalised polypropylenes
This thesis discusses the synthesis of functionalised polypropylenes via a two-step copolymerisation-post-modification strategy. The resulting functionalised polypropylenes display distinctly altered bulk and surface properties, compared to polypropylene,

Advanced Functional Materials, EarlyView.A mechanically programmable hydrogel for tissue engineering is developed by modulating the molecular threading density of poly(ethylene glycol) diacrylate‐β‐cyclodextrin (PEGDA‐β‐CD) polyrotaxane and combining it with β‐CD‐modified gelatin. The polyrotaxane‐guided transition from disordered pores to laminar microstructures enables precise tuning ...
