Structure–Property Relationships of Shape Memory, Semicrystalline Polymers Fabricated by In Situ Polymerization and Crosslinking of Octadecyl Acrylate/Polybutadiene Blends

open access: yesMacromolecular Rapid Communications, Volume 44, Issue 1, January 2023., 2023
The development of a semicrystalline, shape memory polymer is synthesized by simultaneous free radical polymerization and crosslinking in a blend of polybutadiene and octadecyl acrylate, enabling the melt fabrication of complex 3D molded shapes with potential use in anticounterfeiting and antitampering applications.

A multirobot system for autonomous deployment and recovery of a blade crawler for operations and maintenance of offshore wind turbine blades

open access: yesJournal of Field Robotics, Volume 40, Issue 1, Page 73-93, January 2023., 2023
Abstract Offshore wind farms will play a vital role in the global ambition of net zero energy generation. Future offshore wind farms will be larger and further from the coast, meaning that traditional human‐based operations and maintenance approaches will become infeasible due to safety, cost, and skills shortages.

Stepless shape morphing polymer

open access: yesSmartMat, Volume 4, Issue 1, February 2023., 2023
Reversible stepless discretionary morphing polymer is produced by simply training commercial ultrahigh molecular weight polyethylene (UHMWPE) via thermal treatment associated stretching. The key issue is that the crystals of UHMWPE memorize lots of temporary shapes as independent switching phases.

Interfacial Yield Stress Response in Synthetic Mucin Solutions

open access: yesAdvanced Materials Interfaces, EarlyView.
The solution rheology of novel synthetic mucins mimicking natural mucin domains is studied. Like many natural mucin solutions, apparent solid‐like rheology is seen. However, no bulk structural features are found to explain it. Interfacial rheology and robust modelling reveal that this arises from molecular associations at the air–water interface ...

Exploring Dark Web Crawlers: A Systematic Literature Review of Dark Web Crawlers and Their Implementation

open access: yesIEEE Access, 2023
Strong encryption algorithms and reliable anonymity routing have made cybercrime investigation more challenging. Hence, one option for law enforcement agencies (LEAs) is to search through unencrypted content on the Internet or anonymous communication networks (ACNs).
