Fiber‐Format Flexible Linear Electrostatic Motors

Advanced Materials, EarlyView.
A flexible coaxial fibre‐format electrostatic motor enables backdrivable and reversible linear actuation with high force density and functionality under bending, offering a scalable actuation platform for soft and wearable robotics. ABSTRACT Linear motion is fundamental to robotics, yet existing solutions are either rigid electromagnetic motors or ...

Phase‐Engineered MoS2 Quantum Monolayer Catalysts

Advanced Materials, EarlyView.
A new type of catalyst model—phase‐engineered MoS2 quantum‐monolayer catalyst (∼0.8 nm thick, < 6 nm in the lateral size; switchable freely among metallic 1T, semiconducting 2H, and a hybrid phase of metallic‐semiconducting 1T‐2H)—is reported. It can efficiently and stably drive photochemical H2, syngas and ammonia synthesis as a catalyst or co ...

Novel Insights into Terrestrial and Extraterrestrial Phenomena Using New Phase Diagrams with Three Pseudosupercritical States, Liquid Boundary, and Dwij Point

The Planetary Science Journal
Phase diagrams with newly discovered supercritical (SC) solid-like state, liquid/liquid-like boundary, and Dwij point, beyond which only gas and solid exist (V. Prasad et al.), can provide new insights into many terrestrial and extraterrestrial phenomena.

Biomass DNA: An Emerging Building Block for Advanced Materials

Advanced Materials, EarlyView.
Biomass DNA is rapidly emerging from its traditional role as a genetic blueprint to serve as a versatile abundant, highly programmable polymeric building block. This review highlights the transformation of macroscopic bulk biomass DNA into next generation of functional materials, spanning from dynamic hydrogels, sustainable bioplastics, and high ...

Suppression of Resonant Overstability at Sharp Migration Gradients

The Astrophysical Journal
Mean-motion resonances are expected to frequently arise at the inner edges of protoplanetary disks, where planet–disk interactions facilitate large-scale orbital convergence.

Synthesis of Ti2B2Clx MBenes in Molten Salts From Theoretical and Experimental Perspectives

Advanced Materials, EarlyView.
By integrating a theoretical framework with experiments, Ti2InB2 was selectively etched with ZnCl2 to produce a multilayer (ml) Ti2B2Clx MBene. The In atoms are completely removed, with simultaneous incorporation of chlorine surface terminations. in situ x‐ray diffraction indicates a direct biphasic transformation from Ti2InB2 to ml‐MBene, with no ...

Distinct impacts of diverse forcing agents on Arctic sea ice since the mid-twentieth century

npj Climate and Atmospheric Science
Arctic sea ice has undergone non-monotonic changes since the middle of the last century. Here, we investigate the cause of this behavior by isolating and quantifying the effects of anthropogenic aerosols, well-mixed greenhouse gases, and biomass burning ...
