Nanocrystals of the three-dimensional, spin-crossover, porous coordination framework [Fe(pz)Pt(CN)4]⋅n H2O (pz=pyrazine; n≤2.5) have been synthesized from water-in-oil microemulsions. The surfactant-free nanocrystals readily desorb water and resulting anhydrous compounds exhibit thermally induced electronic bistability accompanied by a pronounced color change (see picture; HS=high spin, LS=low spin) close to room temperature.
The two-dimensional spin crossover (SCO) polymers [Fe(3-Fpy)2M(CN)4] (MII = Ni(1), Pd(2), Pt(3)) were nanostructured in the form of nanocrystals and nanoparticles, their chemical, structural, physical characterization was carried out using different experimental methods (powder X-ray diffraction, magnetic susceptibility measurements, Mössbauer infrared spectroscopy, transmission scanning electronic microscopy, etc.). Surfactant-free average dimensions 400 × 30 nm (1a, 1a*, 2a, 3a)...
Significance Statement Although gene expression changes have been characterized in human diabetic kidney disease (DKD), unbiased tissue proteomics information for this condition is lacking. The authors conducted an aptamer-based proteomic analysis of samples from patients with DKD and healthy controls, identifying proteins levels that associate function (eGFR) or fibrosis, after adjusting key covariates. Overall, only modestly correlated protein levels. Kidney RNA matrix metalloproteinase 7...

All of the fluoro iodo compounds, as well chloro derivative in which M(II) is Pt, crystallise monoclinic C2/m space group, whereas rest all bromo derivatives orthorhombic Pnc2 group. In cases, iron(II) atom resides a pseudo-octahedral [FeN(6)] core, similar bond...
In Wasser-in-Öl-Mikroemulsionen wurden Nanokristalle des porösen dreidimensionalen Koordinationsnetzwerks [Fe(pz)Pt(CN)4]⋅n H2O (pz=Pyrazin; n≤2.5) synthetisiert. Die tensidfreien geben bereitwillig Wasser ab. So werden wasserfreie Verbindungen erhalten, deren elektronische Bistabilität sich in einem Farbwechsel (siehe Bild) nahe Raumtemperatur äußert.
Assembly of Fe(II), 3-cyanopyridine and [Au(CN)2](-) affords, in one-pot reaction, three coordination polymers that represent a genuine example supramolecular isomerism with strong influence the spin crossover regime Fe(II) ions.
As quantum devices continue to grow in size but remain affected by noise, it is crucial determine when and how they can outperform classical computers on practical tasks. A central piece this effort develop the most efficient simulation algorithms possible. Among promising approaches are Pauli backpropagation algorithms, which have already demonstrated their ability efficiently simulate certain classes of parameterized circuits-a leading contender for near-term advantage-under random circuit...
Compound [Co(4-terpyridone)2](CF3SO3)2·1H2O, where 4-terpyridone is 2,6-bis(2-pyridyl)-4(1H)-pyridone, forms two polymorphs. Polymorph 1 displays a continuous spin conversion in the temperature region 300–120 K while polymorph 2 shows, on cooling, onset of high-spin (HS) to low-spin (LS) interrupted by an abrupt "reverse" transition 217–203 K. The formed unstable HS intermediate phase (IP) undergoes strong cooperative "normal" characterised hysteresis loop 33 wide. structural data give...

Two new isostructural iron(II) spin-crossover (SCO) framework (SCOF) materials of the type [Fe(dpms)2(NCX)2] (dpms = 4,4'-dipyridylmethyl sulfide; X S (SCOF-6(S)), Se (SCOF-6(Se))) have been synthesized. The 2D consist undulating and interpenetrated rhomboid (4,4) nets. SCOF-6(S) displays an incomplete SCO transition with only approximately 30 % conversion high-spin (HS) to low-spin sites over temperature range 300-4 K (T1/2 75 K). In contrast, NCSe(-) analogue, SCOF-6(Se), a complete 135...

For the 2D coordination polymers [Fe(3-Fpy)(2)M(II)(CN)(4)] (M(II) = Ni, Pd, Pt), pressure-induced spin crossover behavior has been investigated at 298 K by monitoring distinct optical properties associated with each state. Cooperative first-order transition characterized a piezohysteresis loop ca. 0.1 GPa wide was observed for three derivatives.

The development of new advanced functionalities, miniaturization, and the aim obtaining optimized performance in electronic devices significantly impacts their electromagnetic compatibility (EMC). As components become more densely packed on a printed circuit board (PCB), unintended coupling between can cause interference (EMI). These requirements result design restrictions that make using level shield (BLS) essential reducing intra-system EMI PCB designs. This contribution focuses studying...

Pancake kidney is one of the least common renal fusion anomalies encountered in medical practice. Less than 30 cases this variant have been reported literature. Patients are generally asymptomatic, with diagnosis pancake usually found incidentally on imaging study or autopsy. Given rarity cases, it difficult to establish a relationship specific associated clinical findings. Asymptomatic patients managed conservatively regular follow-up. We present case 69-year-old female who was kidney,...
