PROBLEM:A gradient sensor can in principle separate ions by depth, with each zone favouring a different ion, but the charge generated in one zone can couple into neighbouring zones and blur the depth information. Selectivity then depends on deconv...

PROBLEM:Electrospun nanofiber mats expose a large biosorbent surface in a flow-through form, but fibres can compact, channel, or shed under flow, and loading is uneven across the mat. A mat that captures well at its inlet face may be nearly unused...

PROBLEM: Environmental compliance depends on continuous, trustworthy records of what a treatment stack removed and when, but layer-by-layer biosorbent systems usually produce only periodic laboratory results. A charge signal generated by flow and ...

PROBLEM: Catalytic conversion in a printed plasmonic scaffold depends on reactants reaching the active sites through the designed pore network while the plasmonic interface stays correctly spaced from those sites. Printing, functionalization, and ...

PROBLEM: A gradient electrode with a plasmonic layer could report interfacial binding at a chosen depth during cycling, but grading porosity and composition through the stack already complicates fabrication, and adding a metal–dielectric structure...

PROBLEM: A plasmonic nanofiber sensor must respond selectively and quickly, yet fiber diameter, pore structure, and plasmonic particle placement all vary across electrospun batches. A fast optical response is only useful if it can be traced to the...

PROBLEM: An ALD oxide layer can protect a plasmonic metal surface while still letting metal ions reach the binding sites, but the oxide thickness controls that trade-off precisely: too thick and the plasmonic field cannot reach the ions; too thin ...

PROBLEM: Monitoring scaffolds printed for field deployment must survive handling, fouling, and regeneration while still producing comparable compliance data across sites. A 3D-printed pore design that works in one water matrix may clog or degrade ...

Idea description: When I prepared a hands-on OpenShift course for a group of engineers, getting each participant an environment raised problems that had nothing to do with technology: Personal registration terms. Free practice environments such ...

I designed and taught a 6-session course on cloud native and microservices architecture, using the Red Hat Developer Sandbox as the only hands-on environment. The Sandbox is excellent for getting started: free, nothing to install, ready in minutes...
