Microscale Mapping of Fiber Strain and Damage in Composite Wrinkled Laminates Using Computed Tomography Assisted Wide‐Angle X‐Ray Scattering

open access: yesAdvanced Science, EarlyView.
This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...

Probing non-graviton spectra in N = 4 $$ \mathcal{N}=4 $$ SYM via BMN truncation and S-duality

open access: yesJournal of High Energy Physics
The one-loop cohomology of N = 4 $$ \mathcal{N}=4 $$ super Yang-Mills is conjectured to be isomorphic to the exact cohomology. As a result, its truncations are expected to be sub-rings of the exact cohomology. We study the superconformal index restricted

Novel Tio2 Coatings For Visible Light-Responsive Titanium Implants

open access: yesInternational Dental Journal
Aim or purpose: Peri-implantitis is a key challenge in implant dentistry. In recent years, TiO2 as a pho-tosensitizer of photodynamic antimicrobial therapy (APDT) is often preferred in the treatment of peri-implantitis.

Will we use Micro Black Holes to Power Spacetime Warping for Creating MicroWormholes?

open access: bronzeInternational Journal of Theoretical & Computational Physics
In the realm of theoretical physics, the concept of harnessing micro black holes for spacetime warping and the creation of micro wormholes presents a highly ambitious and intriguing idea. The proposition, originating from Zhan-Feng Mai and Run-Qiu Yang of Tianjin University in China, revolves around the utilization of ultra-dense primordial black holes

Gravitational Waves from Micro Black Hole Binaries and Quantum Mechanics

open access: yes, 2020
This paper was written to graduate and postgraduate students of Physics. We study the emission of gravitational waves by binaries composed by micro non-charged black holes (mBH). It is assumed that the mBHb dynamics obeys General Relativity and that its inspiral motion can also be described by a quantum approach given by the Schrödinger-Newton equation,

Metal‐Enhanced Charge Transport and its Mechanism in Atomically Precise Ruthenium Single‐Molecule Devices

open access: yesAdvanced Science, EarlyView.
An atomically precise platform was developed for investigating single‐molecule charge transport. This innovative platform enables the creation of highly uniform molecular devices using ruthenium‐based molecules. It reveals a significant enhancement in molecular conductance due to the metallic ruthenium center and a unique barrier‐lowering effect during

Ultra-long Gamma-ray Bursts from Micro-Tidal Disruption Events: The Case of GRB 250702B

open access: yesThe Open Journal of Astrophysics
Ultra-long gamma-ray bursts (ULGRBs), a rare class of high-energy transients with durations $>10^3$s, remain poorly understood. GRB 250702B is notable for its multi-hour prompt emission, an X-ray pre-peak emission starting ~1 day earlier, off-nuclear ...

Recent Advances in Laser‐Induced Graphene‐Based Gas Sensors: From Sensing Mechanisms to Biomedical Applications

open access: yesAdvanced Science, EarlyView.
Laser‐induced graphene (LIG) provides a scalable, laser‐direct‐written route to porous graphene architecture with tunable chemistry and defect density. Through heterojunction engineering, catalytic functionalization, and intrinsic self‐heating, LIG achieves highly sensitive and selective detection of NOX, NH3, H2, and humidity, supporting next ...

Five-Hundred-Meter Aperture Spherical Radio Telescope (FAST): A Powerful Explorer of Exotic Pulsars

open access: yesUniverse
Located in southern China, the five-hundred-meter aperture spherical radio telescope (FAST) is the world’s most sensitive radio telescope, especially for pulsar observation. Since its commissioning in 2016 and full operation in 2020, it has detected over
