Yolk–Shell Nanostructure: An Ideal Architecture to Achieve Harmonious Integration of Magnetic–Plasmonic Hybrid Theranostic Platform

Yolk–shell structured Fe3O4@Au nanoparticles are designed to circumvent the decline in relaxivity of magnetic component caused by the introduction of water-impenetrable plasmonic components, which is unavoidable in traditional core–shell structured nanostructures. This feature, in conjunction with their compact size, near-infrared absorption, and drug delivery capability, makes them harmoniously integrated magnetic–plasmonic theranostic nanoplatforms for multimodal imaging and light-triggered chemothermal synergistic therapy.

Field-Induced Slow Magnetic Relaxation of GdIII Complex with a Pt−Gd Heterometallic Bond

Field‐Induced Slow Magnetic Relaxation of GdIII Complex with a Pt−Gd Heterometallic Bond

Relax and go slow! A new strategy is reported in which a diamagnetic Pt ion was used as a ligand on a Gd ion to bring about SMM-like behavior in a Gd complex. The heterometallic Gd−Pt bond lowers the symmetry of the Gd ion, splitting the Kramers doublet in a dc field. Thus, the complexes should undergo slow magnetic relaxation.

Experimental and Theoretical Examination of the Radical Cations Obtained from the Chemical and Electrochemical Oxidation of 5‐Aminothiazoles

A little bit of magic: 5-Aminothiazoles are subjected to chemical and electrochemical oxidation to afford the corresponding radical cations. These radicals show broad absorption spectra and half-life times of up to several days. DFT calculations support the experimentally observed substantial bathochromic shifts in the maximum absorption wavelengths of the 5-aminothiazoles upon oxidation.

Guiding Brain‐Tumor Surgery via Blood–Brain‐Barrier‐Permeable Gold Nanoprobes with Acid‐Triggered MRI/SERRS Signals

Gold nanoprobes are developed to guide brain-tumor surgery by crossing the blood–brain barrier. Assembly of the nanoprobes in the acidic tumor extracellular fluid triggers the activation of both the magnetic resonance signal for preoperatively defining the tumor margins and the surface-enhanced resonance Raman spectroscopy signal for intraoperatively guiding the tumor surgery. These nanoprobes are promising candidates to improve the outcome of brain-tumor surgery.

A Density Functional Theory Investigation of Nin, Pdn, and Ptn Clusters (n=1–4) Adsorbed on Buckminsterfullerene

A Density Functional Theory Investigation of Nin, Pdn, and Ptn Clusters (n=1–4) Adsorbed on Buckminsterfullerene

Clusters on Bucky balls: How Ni, Pd, and Pt clusters adsorb on C60 is examined by using a computational approach. The calculations show that the base structure of C60 can host Nin/Pdn/Ptn (n=1–4) clusters with good adsorption stability and the complexes establish either two or no unpaired electrons. The binding energy of Pd and Pt clusters increases as the number of metal atom increases, which implies that the coverage of C60 with Pd or Pt preferentially establishes a large-size metal cluster.

Injected hydrogels in immunocompetent mice and release of encapsulated compound are monitored up to 9 months by magnetic resonance imaging and optical imaging. This surprisingly stable hydrogel does not cause adverse inflammatory response, while its degradation is associated with invasion of macrophages and vascular formation.

Room temperature ferromagnetic‐like response in “bulk” Y‐doped CeO2

Bulk (∼600 nm) crystallites of heavily Y-doped CeO2 display remarkable ferromagnetic-like response at room temperature. This response can be linked to the formation of defect-lined nanodomain interfaces in the interior of heavily doped crystals that result in the appearance of coherent mesoscopic domains with giant orbital paramagnetism.

Solvent donicity makes the difference: Accurate NMR chemical shift analysis discloses a subtle balance between ion association and ion solvation in mixtures of imidazolium ionic liquids and polar molecular solvents. The less polar but more donating γ-butyrolactone favors cation solvation more than propylene carbonate. Anions modulate this effect via competing cation–anion interactions.

Introducing Barium in Transition Metal Oxide Frameworks: Impact upon Superconductivity, Magnetism, Multiferroism and Oxygen Diffusion and Storage

Introducing Barium in Transition Metal Oxide Frameworks: Impact upon Superconductivity, Magnetism, Multiferroism and Oxygen Diffusion and Storage

Strongly correlated electron systems are observed for mixed valent transition metal oxide frameworks hosting alkaline earth and lanthanide cations. The introduction of barium in the cavities of the oxide framework allows generally an ordering with other cations due to its larger size. The specific affinity of barium with respect to oxygen allows the oxygen content, and consequently the electronic charge distribution to be tuned and favors oxygen and anionic vacancies ordering. These two specific characteristics allow best performances to be reached as well for the physical properties, such as superconductivity, magnetism or multiferroicity as for oxygen storage.
