Article Synopsis
- A study evaluated a 10-week Mind-Body Medicine course aimed at improving medical student self-care at Charité Universitätsmedizin Berlin, focusing on stress reduction and overall health.
- Data from 112 students showed that participation significantly decreased perceived stress and increased levels of self-efficacy, mindfulness, self-reflection, and empathy.
- Qualitative feedback indicated students felt better equipped to handle stress, experienced personal growth, and gained valuable insights into doctor-patient relationships, highlighting the social context of their experiences.
The {Pd84 }(Ac) wheel, initially discovered serendipitously, is the only reported giant palladium macrocycle-a unique structure that spontaneously assembles from small building blocks. Analogues of this structure are elusive. A new modular route to {Pd84 }(Ac) is described, allowing incorporation of other ligands, and a new screening approach to cluster discovery.

Not only does the symmetry give rise to a non-closest packed structure, the mechanism of the wheel formation is proposed to depend on the delicate balance between reaction conditions. We achieve the resolution of gigantic polyoxopalladate species through electrophoresis and size-exclusion chromatography, the latter has been used in conjunction with electrospray mass spectrometry to probe the formation of the ring, which was found to proceed by the stepwise aggregation of {Pd6}(-) = [Pd6O4(CH3CO2)2(PO4)3Na(6-n)H(n)](-) building blocks.

- Molecular self-assembly is a promising method for creating nanotechnology structures from atoms, but predicting these structures remains challenging.
- Researchers discovered a palladium oxometalate cluster, {Pd(84)}, which is about 3.3 nm in size and forms simply by mixing two chemicals in water at room temperature.
- The cluster has a unique sevenfold symmetry and consists of 196 building blocks, leading to insights into the relationships between different molecular inorganic nanostructures that can help predict other similar structures.
Article Synopsis
- A polyoxopalladate compound with a high nuclearity, [Pd(II)(2)⊂{H(7)Pd(II)(15)O(10)(PO(4))(10)}](9-) {Pd(II)(17)}, consists of a {Pd(15)} host with a {Pd(2)} guest, and both have been characterized using various techniques, including X-ray crystallography.
- The encapsulated {Pd(2)} exhibits a close Pd(II)-Pd(II) distance within the {Pd(15)} host.
- Studies indicate a dynamic equilibrium between the empty host and the filled guest complex, with UV titrations showing a binding constant of approximately 10(3)
