Metal-organic frameworks study unravels mechanism for capturing water from air
Researchers from the Helmholtz-Zentrum Dresden-Rossendorf and Dresden University of Technology have unraveled the water adsorption mechanism in certain microporous materials—so-called hierarchical metal-organic frameworks (MOFs)—while probing them on the atomic scale. Discovered only about 25 years ago, their special properties quickly led to a reputation as "miracle materials"—which, as it turned out, can even harvest water from air. The researchers describe how the material achieves this in ACS Applied Materials & Interfaces. "These very special materials are highly porous solids made of metals or metal-oxygen clusters which are connected in a modular way by pillars of organic chemicals. This 3D arrangement leads to networks of cavities reminiscent of the pores of a kitchen sponge. It is precisely these cavities that we are interested in," says Dr. Ahmed Attallah of HZDR´s Institute of Radiation Physics.

Silicon 14 (Si) - Beep Boop. Computer time. Along with being most of sand, and many ceramics, concrete, quartz and glass. Very very widespread. Could be a basis for life as an alternative to carbon.
vs
Zirconium 40 (Zr) - The key component of Zircon and Cubic Zirconia, which are gemstomes. Cubic Zirconia is visually very similar to diamond, and to the untrained eye will well and truly do the job.

Rock Expo Day 2
Finally have a minute to catch my breath! Sorry for the delay, Easter weekend jam-packed itself while I wasn’t looking. Here are the photographs from day two of the rock expo!
First: that SLAB of Lapis I was goin on about
Tumblr media
Did you know Lapis Lazuli glows under black light? The Lazuli part fluoresces. Speaking of fluorescence, Let’s talk about Fluorite! Yes, both words come from the same root, the Latin “fluere,” which means “to flow.”
Tumblr media
This wavy fluorite bowl was longer than my forearm, as was the cookie-colored Onyx bowl behind it.
This one would taste like a purple otter pop if you licked it, I think:
Tumblr media
If ever there was a rock pretty enough to eat though, it’d be Amber. The rich honey tone of this rock reminds me of the inside of our old behive, all aswarm with glossy golden bodies and irridescent wings.
Tumblr media
Bring me some royal jelly, becauseI feel like a queen wearing this beautiful sample:
Tumblr media
The convention also served as a venue for adjacent trades. There were many booths devoted to spirituality and crystal healing. There were booths looking less to sell, and more to educate, such as this well-labeled display of specimines:
Tumblr media
And then there booths like this one, which sold lamps, with wares pretty enough to rival pearls.
Tumblr media Tumblr media
Oh! The pearls! 
Tumblr media
These are Baroque Pearls. They represent a conundrum of the gemstone world: The more even and regular a stone is, the more likely it is to be fake, but when natural stones are even and regular, they’re worth more. 
That slab of Lapis from the start is very, very high quality, which you can tell because of its deep, even blue. There’s few veins of other, contaminating minerals. However, you can tell it’s genuine from the uneaven stripe of whitish stone running down the center.
Because Baroque Pearls are defined as any pearl which is irregular in size, shape, or color, it’s easy to tell if they’re genuine. However, since they’re so uneven, they’re considered a less expensive form of pearl. Figures!
As a palate cleanser, here’s bucket of raw garnets
Tumblr media
And finally, the last picture from the fair, some sparkly zirconium, cut for jewelry:
Tumblr media Tumblr media
So there you have it folks! Some Very Neat Rocks! Happy Easter C:

Design, synthesis and applications of functional zirconium-based metal-organic frameworks
In a review led by Prof. Zhijie Chen's group from Department of Chemistry at Zhejiang University, an overview of recent progress in the development of Zr-MOFs is provided. The article titled "Design, synthesis and applications of functional zirconium-based metal-organic frameworks" is published in the journal Science China Chemistry. The authors summarize how reticular chemistry can be applied to the design, synthesis, and applications of some representative Zr-MOFs. Furthermore, the authors also provide an outlook on the future development of Zr-MOFs. The authors first introduce reticular chemistry and how it can be applied to the rational design and synthesis of Zr-MOFs to achieve the targeted structure and/or properties. Synthetic strategies, including isoreticular expansion, linker functionalization, node functionalization, post-synthetic modification, and defect engineering, are then discussed in the context of applications.
