Architecture‐Driven Functional Coupling in Vertically Aligned Nanocomposites

open access: yesAdvanced Functional Materials, EarlyView.
Vertically aligned nanocomposites define a growth‐engineered architecture in which vertical interfaces, strain fields, defect pathways, and phase connectivity are created simultaneously. This review shows how these architectural features couple ferroic, optical, ionic, electrochemical, and device responses, establishing design rules and open challenges

Influence of the far non-resonant components of high-n resonant magnetic perturbations on energetic passing ions loss

open access: yesNuclear Fusion
The influence on the loss of energetic passing ions by the n  = 4 resonant magnetic perturbation (RMP) is investigated through numerical simulations (here, n is the toroidal mode number of the RMP field).

Ground‐State Charge‐Transfer Doping in Donor–Acceptor Semiconducting Polymers

open access: yesAdvanced Functional Materials, EarlyView.
This work demonstrates controlled ground‐state charge‐transfer complex formation (GS‐CTC) and doping in a series of diketopyrrolopyrrole‐based donor–acceptor semiconducting polymers paired with a π‐conjugated penta‐t‐butylpentacyanopentabenzo[25]annulene “cyanostar” macrocycle. Complementary experimental techniques show how subtle molecular, electronic,

Particle transport as a result of resonant magnetic perturbations [PDF]

open access: yes, 2011
This thesis makes contributes to field of plasma physics with a particular focus on particle transport as a result of resonant magnetic perturbations (RPMs) in magnetic confinement devices (Tokamaks). RPMs have proven to be a useful technique to suppress

Sensitivity of magnetic islands in permanent magnet stellarators using the gradient and Hessian methods

open access: yesNuclear Fusion
Stellarator plasmas are known to be very sensitive to perturbations in the magnetic field. The permanent magnet stellarator was in part developed as a solution to high machining tolerances placed on the shape properties of electromagnetic coils in ...

Two-degree-of-freedom control scheme for flying-height and tracking-position controls with thermal actuators in HDDs

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2018
To improve positioning accuracy of a magnetic head in hard disk drives (HDDs), a triple-stage-actuator system was proposed with a thermal positioning actuator for a magnetic head positioning system. This positioning system has three types of actuators: a

Giant Magnetic Purcell Effect Induced by High-Order Mie Resonances. [PDF]

open access: yesAdv Sci (Weinh)
High‐order Mie resonances in dielectric spheres selectively amplify magnetic dipole emission from Eu3+ emitters, producing a giant magnetic Purcell effect. Localized emitters can efficiently access high‐order resonant modes, and the low‐loss TiO2 platform enables direct far‐field observation of the enhanced emission.

Stereometric Molecular Engineering for Ultra‐Stable Aqueous Zinc‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Stereochemical configuration of molecular additives greatly influences interfacial adsorption at the Zn surface. The optimal tilted dual‐anchored adsorption geometry of myo‐inositol constructs a water‐deficient interface and regulates the solvation structure.

Active control of Alfvén eigenmodes by external magnetic perturbations with different spatial spectra

open access: yesNuclear Fusion
Alfvén eigenmodes have been suppressed and excited in tokamak plasmas by (just) modifying the poloidal spectra of externally applied static magnetic perturbations.

Charge‐Polarized Ni─S4 Single‐Atom Sites Drive Selective Photoreforming of Poly(lactic acid) to Lactate and Hydrogen

open access: yesAdvanced Functional Materials, EarlyView.
Atomically dispersed Ni–S4 sites on CdS nanorods induce interfacial charge polarization, directing photogenerated electrons to H2 evolution and holes to selective ester‐bond cleavage of poly(lactic acid). Without sacrificial reagents, this charge‐coupled system produces lactate while suppressing overoxidation, achieving an H2 evolution rate of 41.74 ...
