INTRODUCTION Decades of research have been devoted to studying the properties of nanostructured materials-e.g.,single crystalline wires,porous materials,polycrystals and laminatesfor applications ranging from heterogeneous catalysts to highstrength structures.1 Interest in nanoscale materials is motivated by their new(and often enhanced)properties,which are attributed to large interfacial areas and high surface defect concentrations.2 Nanoscale catalysts exhibit superior activities due to surface strains,increased population of dangling bonds,and unique surface electronic states established by surface/subsurface atomic interactions.3,4 For instance,bulk Au surfaces are relatively inert but Au nanoparticles exhibit excellent catalytic behavior.1,3 In a similar fashion,nanocrystalline metals possess exceptionally high yield strengths due to an increased barrier for plasticity mechanisms to operate in confined volumes and in close proximity to interfaces.1,2,5 Unfortunately,fabrication techniques for these materials are frequently resource-intensive and cannot be translated into commercial-scale processing.

The brain's extracellular matrix(ECM),which is comprised of protein and glycosaminoglycan(GAG)scaffolds,constitutes 20%-40% of the human brain and is considered one of the largest influencers on brain cell functioning(Soles et al.,2023).Synthesized by neural and glial cells,the brain's ECM regulates a myriad of homeostatic cellular processes,including neuronal plasticity and firing(Miyata et al.,2012),cation buffering(Moraws ki et al.,2015),and glia-neuron interactions(Anderson et al.,2016).Considering the diversity of functions,dynamic remodeling of the brain's ECM indicates that this understudied medium is an active participant in both normal physiology and neurological diseases.

The Globus Toolkit （GT） has been developed since the late 1990s to support the development of serviceoriented distributed computing applications and infrastructures. Core GT components address, within a common framework, fundamental issues relating to security, resource access, resource management, data movement, resource discovery, and so forth. These components enable a broader ＂Globus ecosystem＂ of tools and components that build on, or interoperate with, GT functionality to provide a wide range of useful application-level functions. These tools have in turn been used to develop a wide range of both ＂Grid＂ infrastructures and distributed applications. I summarize here the principal characteristics of the recent Web Services-based GT4 release, which provides significant improvements over previous releases in terms of robustness, performance,, usability, documentation, standards compliance, and functionality. I also introduce the new ＂***＂ community development process, which allows a larger community to contribute to the development of Globus software.
