Phase Engineering of Nanomaterials (PEN): Evolution, Current Challenges, and Future Opportunities

Advanced Materials, EarlyView.
This review summarizes the synthesis, phase transition, advanced characterization spanning ex situ to in situ and operando techniques, and diverse applications of phase engineering of nanomaterials (PEN). It further outlines key challenges and future opportunities, such as phase stability, architecture control, and artificial intelligence (AI)‐driven ...

Can Elastomers Combine Stiffness, Toughness and Fatigue Resistance?

Advanced Materials, EarlyView.
This review studies how the molecular and macroscopic architecture of elastomers influence their mechanical properties including: stiffness, stretchability, toughness, fatigue resistance, and damping behavior. By linking the structure to performance, it proposes design principles for advanced elastomeric systems that combine mechanical properties ...

Nano‐Architected Metallic Metamaterial With Enhanced Fatigue Resistance via Dislocation Starvation

Advanced Materials, EarlyView.
Nanoscale Ni single crystals exhibit remarkable fatigue resistance over an order of magnitude higher than that of bulk single crystals through dislocation starvation. By translating this mechanism into geometric nano‐architecture, nano‐architected Ni single‐crystal metamaterials achieve about twice the fatigue resistance of the bulk, despite their ...

Cabin Altitude Looks Like a Setting on the Passengers' Side, but One Proportionality Turns It Straight into Skin Thickness ── lowering the cabin altitude by 600 m, from 2400 to 1800 m, multiplies the differential pressure by 1.110646, and holding the stress fixed takes 1.110646 times the thickness ── the separator is whether cabin altitude is a setting on the passengers' side or a load on the structure's ── [Paper 727]

Where to set the cabin pressure looks like a question of passenger comfort. In fact one proportionality turns it into the thickness of a sheet of metal. That comfort and weight are joined by a single number is shown. No new theorem or law is claimed. Scope of this paper (scope note): No new theorem or law is claimed──the standard atmosphere, the hoop ...

TESCLA: A Fully Soft Electromagnetic Linear Actuator With Continuous Bending Enabled by Liquid‐Metal Solenoids

Advanced Materials, EarlyView.
TESCLA (tubular electromagnetic soft conformal linear actuator) combines liquid‐metal solenoids and compliant magnetic composites to achieve large‐stroke bidirectional actuation with continuous bending. Integrated inductance‐based self‐sensing enables proprioceptive position estimation without external sensors, providing a versatile platform for soft ...

Three Equal Masses: the Spinning Triangle's Disturbance Multiplies Each Period, the Figure Eight's Only Adds ── the figure-eight solution is a choreography collinear six times a period whose mean potential energy is exactly twice its energy, while the triangle with Routh value 9 loses its side ratios within 4 periods ── the separator is whether disturbance growth is set by a factor per period or by an increment per period ── [Paper 1009]

Three equal masses under gravity admit a triangle that spins keeping its shape (Lagrange 1772) and a solution in which the three chase each other along one figure-eight curve (Moore 1993, Chenciner and Montgomery 2000). This paper puts disturbances of the same size into both and counts their growth per period by numerical integration, and also checks ...

Topological Spin‐Texture Transitions in van der Waals Magnets Revealed by X‐Ray Fourier Transform Holography

Advanced Materials, EarlyView.
Applied here for the first time to a 2D material, high‐resolution synchrotron x‐ray Fourier transform holography directly images topological spin textures in Fe3GeTe2. Combined with atomistic tight‐binding simulations including itinerant electrons and Rashba spin‐orbit coupling, the approach reveals labyrinth, skyrmion, and mixed phases, and uncovers ...

Computation‐Less, Bias‐Free, and Ultra‐Broadband Photodetector for On‐Chip Edge Extraction

Advanced Materials, EarlyView.
A computation‐less, bias‐free, and ultra‐broadband photodetector directly converts local optical‐intensity gradients into signed photocurrents through a position‐dependent bi‐directional photoresponse. This intrinsic physical sensing mechanism enables single‐pixel edge extraction from the near‐infrared to the long‐wave infrared at room temperature ...
