Chemical reactions driven by high electrical currents weaken solid electrolyte materials, causing dendrite growth at low stress levels, which disproves the long-held hypothesis that dendrite formation is primarily driven by mechanical stress.

Researchers at the University of Bath developed a renewable, bio-based polymer membrane that effectively captures and holds toxic perfluorooctanoic acid (PFOA) from water. The nanofibers in the membrane structurally reorganize and tighten when exposed to water, creating a net-like mechanism that traps stubborn "forever chemical" pollutants directly inside the polymer network.

Another photo from my training, this time captured during the analysis of a polymer sample under the light microscope ✨🔬

The material is based on a polycondensation reaction of 4,4´-dihydroxybiphenyl with an aliphatic dicarboxylic acid chloride. Using an aqueous phase with sodium hydroxide and a phase transfer catalyst results in a polymer whose structure and properties strongly depend on the ordering of its molecular chains.

It becomes especially interesting when looking at the thermal and optical properties. In differential scanning calorimetry (DSC), the material shows two endothermic transitions. This means that the ordered structure is not lost all at once, but stepwise via a liquid crystalline phase into a fully isotropic state.

Under the polarizing microscope, this order becomes directly visible. The sample exhibits birefringence, meaning direction-dependent refraction of light. This only occurs when regions within the material are organized on a scale comparable to the wavelength of light. These structures are exactly what create the fascinating patterns and colors in the image.

In short, a small window into the world of liquid crystals, somewhere between ordered structure and thermally driven disorder.

I love these moments when chemistry is not only measurable, but also visible.

The #ecological hybrid dryer is an advanced #agricultural dehumidification device designed specifically for high-latitude regions with cold but highly illuminated "northern" summers. It utilizes solar energy combined with a thermal-storage core to provide continuous, 24-hour food dehydration without relying on conventional electrical grids.

A supersolid is an exotic #quantum state of matter that simultaneously exhibits the ordered, crystal-like spatial structure of a solid and the frictionless flow of a superfluid. Researchers have successfully generated this state at room temperature by engineering light-matter interactions within a nanoscale device.
