Sticks and stones may break my bones, but hydrogels will never hurt me

Recent advancements in tissue engineering have led to the fabrication of complex materials that may be used as surrogates for heart, neuronal, bone and cartilage tissue regeneration. A vast majority of engineered tissues are composed of a three-dimensional scaffold at its core, layered with growth stimulating agents, that collectively nurture and support cell growth.

In a study by Gantar and colleagues at the Jozef Stefan Institute, Department for Nanostructured Materials in Slovenia,  a team of researchers created an injectable hydrogel as a potential biomaterial for bone tissue regeneration. They further demonstrate that the hydrogel is capable of self-healing and supports the growth of cells derived from human bone tissue.

Hydrogels based on reversible covalent bonds allow the material to rearrange its structure permanently. This forms the basis for self-healing. A potential drawback is that the conditions (temperature and pH) required to form these bonds to form are not suitable for supporting bone cell growth. Having recognized this limitation, the team decided to develop a liquid hydrogel that transitions to a gel-like state at a pH suitable for cell growth and proliferation. Further, the hydrogel was infused with bioactive glass (BAG) nanoparticles – a silica-based material known to support bone cell growth.

The study also characterizes the physical (elastic properties, compression) and biological (degradation, cytotoxicity) features of the injectable hydrogel. The study finds that the BAG nanoparticles do not drastically alter the physical and biological properties of the hydrogel and suggest that the combination is well suited to support bone cell growth. The team proposes that their efforts will contribute toward the development of an injectable material that will scaffold bone cells within the host and promote self-repair.

RSC Supramolecular Chemistry Award for Editor-in-Chief Mike Ward

Each year the Royal Society of Chemistry presents prizes and awards to chemical scientists who have made a considerable contribution in their area of research, in industry and academia. This year, we are delighted to announce that RSC Advances Editor-in-Chief, Professor Mike Ward of the University of Sheffield, UK, has been awarded the 2016 RSC Supramolecular Chemistry Award, for his leading contributions to the synthesis, characterisation, host-guest chemistry and functional properties of self-assembled coordination cages.

The Supramolecular Chemistry Award is awarded biennially and recognises studies leading to the design of functionally useful supramolecular species.

In celebration of the 2016 RSC Prizes and Awards, we have collected together some of the research recently published by the winners. This collection showcases articles authored by the winners from across the Royal Society of Chemistry’s journals portfolio, which are free to access for a limited period. A full list of 2016 winners and more information about RSC Prizes and Awards can be found here.

Please join us in congratulating Mike on this achievement!

We would like to highlight the RSC Advances themed collection, Supramolecular chemistry: self-assembly and molecular recognition, Guest Edited by Mike Ward.

The articles in this issue cover many aspects of the formation of, and molecular recognition with, non-covalent self-assembled systems. Systems studied span the range of supramolecular assemblies from MOFs to gels, and potential applications or functional behaviour that are on display here include host/guest chemistry, spin crossover, molecular sensors, and extraction/separation. This collection of articles powerfully illustrates the diversity and increasing importance of supramolecular chemistry.

Introducing the organic chemistry collection

This organic chemisty collection has been collated by Editorial Board member Professor Russell Cox (Leibniz University Hannover, Germany). It brings together articles with the continued aim of inspiring new authors to submit their best work to the journal, and also to highlight great work by regular authors. These articles are already among the most highly cited works in the journal, illustrating their impact.

The subject areas of the articles include those traditionally regarded as organic, such as synthesis, catalysis, heterocyclic and organometallic chemistry, natural products chemistry and method development. In addition, the collection also includes articles from overlapping areas, such as green chemistry, fuel production, ionic solvents and materials chemistry, where there is a strong organic and biological component. Underpinning all are theoretical and computational studies. Finally, emerging areas, including photovoltaics and chemical biology, have strong organic chemistry foundations and also find a natural home in this RSC Advances collection.

This selection aims to illustrate the breadth, depth and impact of papers published in RSC Advances in the area of organic chemistry and stimulate new submissions in these and allied areas.

The collection contains reviews, communications and full papers, all of which can be found here.

Supramolecular Chemistry Themed Collection now online

The latest RSC Advances web-collection on the topic of Supramolecular Chemistry is now available to view online!

The anion complexation properties of a fluorinated alcohol that is isosteric with a simple isophthalamide revealed that the alcohol can complex weakly basic anions with stability constants greater than those of the isophthalamide.The title of the collection is ‘Supramolecular chemistry: self-assembly and molecular recognition’ and is Guest Edited by Professor Mike Ward (University of Sheffield, UK). The articles presented here cover many aspects of the formation of, and molecular recognition with, non-covalent self-assembled systems. Systems studied span the range of supramolecular assemblies from MOFs to gels, and potential applications or functional behaviour that are on display here include host/guest chemistry, spin crossover, molecular sensors, and extraction/separation.  This collection of articles powerfully illustrates the diversity and increasing importance of supramolecular chemistry, and we hope you enjoy reading it.

Graphene and platinum are brought together for fuel cells

Graphene is certainly a hot topic in research right now. A quick look down this very blog shows that it featured in no fewer than seven of the top ten accessed articles in RSC Advances during 2012 (including all of the top three)!

This versatile material appears as oxides, composites, quantum dots, nanomaterials and foams and it has been investigated for uses in photocatalysis, energy, environmental applications and more.

Now researchers in India and China have been investigating graphene supported platinum catalysts for fuel cells.Platinum nanostructures on graphene catalysing oxygen reduction

Sreekuttan M. Unni and colleagues report the first synthesis of a 3D self-assembled single crystalline platinum nanostructure directly on a graphene surface without structural directing agents, by using a slow reduction method. In their paper, they show superior electrocatalytic activity towards the oxygen reduction reaction, a crucial reaction for hydrogen-fuelled polymer electrolyte fuel cells. They show that their material also has less vulnerability to strong hydroxyl adsorption and a higher limiting current density than other graphene supported platinum or commercial platinum-on-carbon catalysts.

Meanwhile Jian Zhao and colleagues have published about their supercritical fluid route for preparing graphene-supported platinum-ruthenium nanoparticles in an effective, simple, low temperature and environmentally benign way. They used supercritical CO2 to uniformly distribute ultrafine PtRu nanoparticles with an average size of 2.87 nm on the surfaces of functionalized graphene sheets. They found considerably improved catalytic activity and stability for methanol oxidation from their supported nanoparticles because of the uniform distribution. Their supercritical approach may have promise for development of direct methanol fuel cells.
