MAGNETORHEOLOGICAL COMPOSITE MATERIALS (MRCMS) FOR INSTANT AND ADAPTABLE STRUCTURAL CONTROL

Redazione
(AGENPARL) – WASHINGTON (DC), mar 17 novembre 2020 Abstract: Magnetic responsive materials can be used in a variety of applications. For structural applications, the ability to create tunable moduli from relatively soft materials with applied electromagnetic stimuli can be advantageous for light-weight protection. This study investigated magnetorheological composite materials involving......

SIMULATIONS OF STRUCTURE FORMATION BY CONFINED DIPOLAR ACTIVE PARTICLES

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), mar 20 ottobre 2020 Dipolar active particles describe a class of self-propelled, biological or artificial particles equipped with an internal (typically magnetic) dipole moment. Because of the interplay between self-propulsion and dipole–dipole interactions, complex collective behavior is expected to emerge in systems of such particles.......

LANTHANOID PYRIDYL-β-DIKETONATE ‘TRIANGLES’. NEW EXAMPLES OF SINGLE MOLECULE TOROICS

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), mar 20 ottobre 2020 Trinuclear lanthanide clusters have been synthesised and investigated as toroidal spin systems. A pyridyl functionalised β-diketonate, 1,3-bis(pyridin-2-yl)propane-1,3-dione (DK-H) has been used to synthesise a family of clusters of the form [Dy3(OH)2(DK)3Cl2(H2O)4]Cl2.7H2O (1), [Tb3(DK)3(μ3-OH)2(CH3CH2OH)3Cl3][Tb3(DK)3(μ3-OH)2(H2O)(CH3CH2OH)2Cl3]Cl2.H2O (2), [Ho3(OH)2(DK)3Cl(H2O)5]Cl3.3H2O (3) and [Er3(OH)2(DK)3Cl2(H2O)3(CH3OH)]Cl2.3H2O.CH3OH (4).

DYIII SINGLE-MOLECULE MAGNETS FROM LIGANDS INCORPORATING BOTH AMINE AND ACYLHYDRAZINE SCHIFF BASE GROUPS: THE CENTROSYMMETRIC {DY2} DISPLAYING DUAL MAGNETIC RELAXATION BEHAVIORS

Redazione
(AGENPARL) – LONDON (UNITED KINGDOM), lun 19 ottobre 2020 Novel multidentate chelating ligands N′-(2-pyridylmethylidene)-2-(2-pyridylmethylideneamino)benzohydrazide (Hpphz) and N′-(2-salicylmethylidene)-2-(2-salicylmethylideneamino)benzohydrazide (H3sshz), which incorporate both amine and acylhydrazine Schiff base groups, were synthesized and investigated in DyIII coordination chemistry. The reactions of Hpphz and Dy(OAc)3∙4H2O have yielded two {Dy2} featuring double OAc- bridges: [Dy2(H2aphz)2(OAc)4(ROH)2]......
