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

Advanced Materials, Volume 38, Issue 15, 12 March 2026.
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.

Formation of Laser‐Induced Periodic Surface Structures on Titanium Alloy Using a Picosecond Laser: Dependence on Fluence and Number of Laser Pulses

Advanced Materials Interfaces, Volume 13, Issue 6, 16 March 2026.
Laser treatment of materials is a versatile technique for generating ordered surface structures. Nevertheless, such structures are the result of laser parameters such as laser pulse fluence. We demonstrate that homogeneous low special frequency laser‐induced periodic surface structures are contingent on both single and effective fluence dose and can be

Electric Method for the Desulfation of Polysaccharides From Red Microalgae (Porphyridium cruentum) Cultures

Biopolymers, Volume 117, Issue 2, March 2026.
A non‐destructive method for depleting sulfates from the red microalgae Porphyridium cruentum by directly exposing the growth medium to a moderate electric field has been developed. The reported electric‐field separation method is a simple, straightforward, and non‐toxic means for the direct recovery of desulfated polysaccharides from P.
