Researchers Study Potential Scaffold Materials for Organizing Nanoparticles into Functional Materials

Home remodelers understand the concept of improving original foundations with more modern elements. Using this same approach—but with chemistry—researchers in the University of Pittsburgh’s Kenneth P. Dietrich School of Arts and Sciences have designed a family of materials that could make drug delivery, gas storage, and gas transport more efficient and at a lower cost. The findings were reported in the latest issue of the Journal of the American Chemical Society (JACS).

Novel Plasmonic Transducer Holds Promise for Ultra-Sensitive Nanoscale Sensors

Researchers at FOM Institute AMOLF in Amsterdam and EPFL in Lausanne have developed a new way to measure tiny displacements with light. By confining plasmons in a resonant cavity that is only 20 nanometers wide, they could precisely measure mechanical motion smaller than the size of an atom. Their work is published this week in the journal Nano Letters.

Novel Mass Spectrometry Imaging Technique Captures Kinetic World of Metabolites

What would you do with a camera that can take a picture of something and tell you how new it is? If you’re Berkeley Lab scientists Katherine Louie, Ben Bowen, Jian-Hua Mao and Trent Northen, you use it to gain a better understanding of the ever-changing world of metabolites, the molecules that drive life-sustaining chemical transformations within cells.

Gold-Indium Alloy Nanoparticles Exposed to Air Become Catalytic Nanostructures

Gold bars may signify great wealth, but the precious metal packs a much more practical punch when shrunk down to just billionths of a meter. Unfortunately, unlocking gold's potential often requires complex synthesis techniques that produce delicate structures with extreme sensitivity to heat.

Dynamic Simulation of Spontaneous Knotting and Unknotting in Polymers

Nanotechnologies require a detailed knowledge of the molecular state. For instance, it is useful to know when and how a generic polymer, a long chain of polymers (chain of beads), knots. The study of molecular entangleme...

Fully Integrated Microfluidic Test-Bed for Solar-Driven Electrochemical Energy Conversion Systems

With the daily mean concentrations of atmospheric carbon dioxide having reached 400 parts-per-million for the first time in human history, the need for carbon-neutral alternatives to fossil fuel energy has never been more compelling. With enough energy in one hour’s worth of global sunlight to meet all human needs for a year, solar technologies are an ideal solution.
