Thickness‐Defined Transport Regime Toward Near‐Ideal Area‐Type Switching
Advanced Materials, EarlyView.By thinning the oxide layer, memristors pass from diode‐like and battery‐effect‐dominated behavior toward eventual short‐circuit failure. Within the intermediate 5–6 nm window, they reach a near‐ideal analog area‐type switching regime, featuring symmetric hysteresis, area‐dependent conductance, and continuous linear programming of HRS and LRS with ...

Starlight-driven flared-staircase geometry in radiation hydrodynamic models of protoplanetary disks
Astronomy & AstrophysicsContext. Protoplanetary disks observed in the millimeter continuum and scattered light show a variety of substructures. While embedded planets are a common explanation, various physical processes in the disk during the early planet formation phase might ...

Vitamin C‐Induced Photo‐Redox Threshold Enables High‐Fidelity Volumetric Printing of Collagen
Advanced Materials, EarlyView.Tomographic volumetric printing (TVP) of native proteins is limited by uncontrolled background crosslinking. Here, vitamin C is introduced as a biocompatible redox regulator to establish a tunable nonlinear polymerization threshold response for TVP.

Radial modes of pressure bumps and dips in astrophysical discs
Astronomy & AstrophysicsAims. We investigate signatures of pressure extrema on global oscillations in discs. Methods. We used the framework of wave topology to establish a generalised local dispersion relation that includes pressure gradients.

From femtonova to supernova: Heavy-ion collisions and the supernova equation of state
EPJ Web of Conferences, 2016 Calculations using astrophysical equations of state at low densities comparable to that of the neutrino emission surface in supernovae and accretion disks are confronted with experimental results from heavy ion collisions.

Constraints on the mass accretion rate of neutrino-cooled disks in gamma-ray bursts [PDF]
, 2008 We present a unified description of all the three known classes of optically thick accretion disks around black holes, namely Shakura-Sunyaev disks, slim disks, and neutrino-dominated accretion flows (NDAFs).

Radiation-driven Origin of Dynamically Significant Magnetic Fields around Accretion Disks
The Astrophysical JournalMagnetic fields play a central role in accretion physics around black holes (BHs), yet their physical origin within accretion flows remains an open problem.

Formation of spirals in early-stage protoplanetary discs
Astronomy & AstrophysicsContext. Class II protoplanetary discs feature numerous non-axisymmetric substructures such as spirals, and the underlying mechanisms for their formation are still highly debated.

Accretion disks with optical depth transition and advection
, 2020 . We consider the effects of advection and radial gradients of pressure and radial drift velocity on the structure of accretion disks around black holes. We concentrated our efforts on highly viscous disk with large accretion rate.
