INTRODUCTION: Erectile dysfunction (ED) affects to some degree approximately 52% of the male population aged 40-70 years. Many men do not respond to, or are precluded from using, pharmaceutical treatments for ED and are therefore advised to consider penile prostheses. Different types of penile prosthesis are available, such as inflatable...

Development of in silico models to guide the experimental characterisation of penile tissue and inform surgical treatment of erectile dysfunction

Fereidoonnezhad, B.F. (author), Akbarzadeh Khorshidi, M. (author), Bose, S. (author), Watschke, B. (author), Mareena, E. (author), Nolan, D. (author), Cooney, S. (author), Lally, C. (author)

This paper presents a computational study to investigate the mechanical properties of human penile tissues. Different experimental testing regimes, namely indentation and plate-compression tests, are compared to establish the most suitable testing regime for establishing the mechanical properties of the different penile tissues. An idealised...

A translation of the structure of mussel byssal threads into synthetic materials by the utilization of histidine-rich block copolymers

Enke, Marcel (author), Bose, R.K. (author), Zechel, Stefan (author), Vitz, Jürgen (author), Deubler, Robert (author), Garcia, Santiago J. (author), van der Zwaag, S. (author), Schacher, Felix H. (author), Hager, Martin D. (author), Schubert, Ulrich S. (author)

Mussel byssal threads are well-known due to their self-healing ability after the mechanical stress caused by waves. The proposed mechanism demonstrates the importance of reversible histidine-metal interactions as well as the block copolymer-like hierarchical architecture of the underlying protein structure. Taking these two aspects as...

Contributions of hard and soft blocks in the self-healing of metal-ligand-containing block copolymers

Bose, R.K. (author), Enke, Marcel (author), Grande, A.M. (author), Zechel, Stefan (author), Schacher, Felix H. (author), Hager, Martin D. (author), Garcia, Santiago J. (author), Schubert, Ulrich S. (author), van der Zwaag, S. (author)

The main aim of this work is to study the respective contribution of the hard and soft blocks of a metal-ligand containing block copolymer to the self-healing behavior. To this aim, different block copolymers containing terpyridine were synthesized using reversible addition-fragmentation chain transfer (RAFT) polymerization. These block...

Effect of the Dianhydride/Branched Diamine Ratio on the Architecture and Room Temperature Healing Behavior of Polyetherimides

Susa, A. (author), Bose, R.K. (author), Grande, A.M. (author), van der Zwaag, S. (author), Garcia, Santiago J. (author)

Traditional polyetherimides (PEIs) are commonly synthesized from an aromatic diamine and an aromatic dianhydride (e.g., 3,4′-oxidianiline (ODA) and 4,4′-oxidiphtalic anhydride (ODPA)) leading to the imide linkage and outstanding chemical, thermal and mechanical properties yet lacking any self-healing functionality. In this work, we have replaced...

Healing of Early Stage Fatigue Damage in Ionomer/Fe₃O₄ Nanoparticle Composites

Post, W. (author), Bose, R.K. (author), Garcia, Santiago J. (author), van der Zwaag, S. (author)

This work reports on the healing of early stage fatigue damage in ionomer/nano-particulate composites. A series of poly(ethylene-co-methacrylic acid) zinc ionomer/Fe3O4 nanoparticle composites with varying amounts of ionic clusters were developed and subjected to different levels of fatigue loading. The initiated damage was healed upon localized...

The spatial distribution of arsenic contamination in fluvial sediment of the Ganges River: Case study from Bihar, India

Donselaar, M.E. (author), Bhatt, A.G. (author), Bruining, J. (author), Bose, N. (author), Ghosh, A.K. (author)

Shallow aquifers in the Ganges River channel belt (Bihar, India) have high and spatially variable concentrations of arsenic contamination. The arsenic is of geogenic origin. Hydrated iron-arsenic-oxide coatings on quartz and clay minerals occur in the Ganges River deposits. The arsenic is subsequently released to the groundwater in a...

Understanding the molecular mechanisms involved in the interfacial self-healing of supramolecular rubbers

Bose, R.K. (author), Garcia Espallargas, S.J. (author), Van der Zwaag, S. (author)

Supramolecular rubbers based on 2-aminoethylimidazolidone and fatty acids with epoxy crosslinks have been shown to self-heal via multiple hydrogen bonding sites. In this work, several tools are used to investigate the molecular mechanisms taking place at the interface to understand cohesive healing in these polymers. The quantification of self...

A study of the temperature dependent healing capabilities of new polymers based on Diels-Alder cycloaddition

Kötteritzsch, J. (author), Hager, M.D. (author), Schubert, U.S. (author), Bose, R.K. (author), Garcia Espallargas, S.J. (author), Van der Zwaag, S. (author)

Because of its thermal reversibility, the retro-Diels-Alder (RDA) reaction represents an appealing possibility to produce self-healing polymers with well-defined architectures and tunable properties [1]. However, the polymer architecture for which the Diels-Alder (DA) reaction can best be used to contribute to the healing process is still not...

Self-healing metallopolymers: Detailed inverstigation of the self-healing properties by scratch testing

Bode, S. (author), Bose, R. (author), Sandmann, B. (author), Hager, M.D. (author), Garcia, S.J. (author), Van der Zwaag, S. (author), Schubert, U.S. (author)

In the last decade several intrinsic self-healing materials have been developed in which the healing mechanism was mainly based on the reversibility of a certain structural element. For this purpose, reversible covalent bonds, e.g., based on the Diels-Alder reaction or weaker non-covalent interactions, e.g., hydrogen bonding, ionic interactions...

Several polymeric systems with intrinsic Self-Healing (SH) capabilities have been reported in literature. Many of them showed healing upon contact across the crack interface. Different parameters such as contact time, temperature, pressure or chemical activity determine the degree of healing obtained. In this work, a numerical simulation of the...
