Breaking the 2‐nm Barrier in Hard Disk Drives Using Monolayer Amorphous Carbon Overcoats

Advanced Materials, EarlyView.
The rapid growth of AI has increased demand for large‐scale data storage, making HDDs indispensable in data centers. Increasing areal storage density is crucial, but limited by the traditional carbon overcoats (COC). Monolayer amorphous carbon (MAC) offers a superior alternative.

Jamming transition in a homogeneous one-dimensional system: the Bus Route Model

, 1997
We present a driven diffusive model which we call the Bus Route Model. The model is defined on a one-dimensional lattice, with each lattice site having two binary variables, one of which is conserved (``buses'') and one of which is non-conserved ...

Meissner Effect and Nonreciprocal Charge Transport in Non‐Topological 1T‐CrTe2/FeTe Heterostructures

Advanced Materials, EarlyView.
This work demonstrates interface‐induced superconductivity (Tc ∼12 K) with a robust Meissner effect and pronounced nonreciprocal transport in epitaxial 1T‐CrTe2/FeTe heterostructures, where 1T‐CrTe2 is a 2D ferromagnet, and FeTe is an antiferromagnetic metal.

Magnetic Flux Guides by Material Extrusion

Advanced Science, EarlyView.
Magnetic flux guidance can increase inductive coupling and forces for magnetic sensors, actuators, and transducers. Here, a magnetic material extrusion method is used to fabricate flux concentration structures of arbitrary shapes with a magnetic permeability of 42. In line with simulation analysis, experimental results show that these materials provide

Low‐Voltage and High‐k Properties of Bilayer HZO Capacitors at the Morphotropic Phase Boundary for Next‐Generation Memory Applications

Advanced Science, EarlyView.
The HfxZr1‐xO2‐based ferroelectric/antiferroelectric bilayer capacitor exhibits morphotropic‐phase‐boundary behavior with a high dielectric constant (∼52) at 2 V. Phase engineering stabilizes o/t‐phase coexistence and suppresses m‐phase formation, enabling capacitance enhancement and self‐optimization under cycling for scalable low‐voltage, high‐κ ...

Thermal Cyclotrimerization Bridges Polymer‐Filler Interfaces for High‐Performance CO2 Separation Membranes

Advanced Science, EarlyView.
Thermal cyclotrimerization of nitriles converts interfacial discontinuity in MAF‐stu‐1/PIM‐1 MMMs into a continuity‐enhanced junction. Triazine–Zn2+ coordination between TR‐PIM chains and MAF‐stu‐1, together with hydrogen bonding and π–π stacking, lowers interfacial tension and builds selective CO2 pathways, enabling > 10 000 barrer CO2 permeability ...
