Making Photoresponsive Metal–Organic Frameworks an Effective Class of Heterogeneous Photocatalyst

open access: yesAdvanced Functional Materials, EarlyView.
This review summarizes photoresponsive MOFs for photocatalytic applications, focusing on their capacity to enhance light harvesting, charge transfer, and surface reactions. While existing studies provide foundational insights, emerging characterization techniques enable a deeper understanding of photoresponsive MOFs.

Negative moment of inertia and rotational instability of gluon plasma

open access: yesPhysics Letters B
Using first-principle numerical simulations of the lattice SU(3) gauge theory, we calculate the isothermal moment of inertia of the rigidly rotating gluon plasma.

Universal Relations for Non-Rotating Objects Made of Dark Energy

open access: yesGalaxies
We obtain universal relations for fluid spheres without rotation made of dark energy assuming the extended Chaplygin gas equation-of-state. After integrating the relevant differential equations, we make a fit to obtain the unknown coefficients of the ...

Bi‐Directional Assembly of Boron Nitride µ‐Platelets by Micro‐Molding for Advanced Thermal Interface Materials

open access: yesAdvanced Functional Materials, EarlyView.
Bi‐directionally assembled BN µ‐platelets in micropatterns formed by a micro‐molding method for thermal interface materials are demonstrated. The BN µ‐platelets are vertically aligned selectively, while compressed regions without patterns accommodate horizontally assembled BN µ‐platelets. Through anisotropic orientation, high thermal conductivities for

Roulette‐Inspired Physical Unclonable Functions: Stochastic yet Deterministic Multi‐Bit Patterning through the Solutal Marangoni Effect

open access: yesAdvanced Functional Materials, EarlyView.
Geometric multi‐bit patterning based on dynamic wetting and dewetting phenomena creates roulette‐like Physical Unclonable Function (PUF) labels with stochastic yet deterministic properties. This method leverages the solutal‐Marangoni effect for high randomness while achieving deterministic multinary patterns through polygonal confinement of binary ...

Calculation of Cross-sectional Shape and Polar Moment of Inertia of a Thread Screw

open access: yesJixie chuandong, 2016
According to the characteristic of the trapezoidal thread screw,at first,the equation of the cross- section shape intersecting line is deduced,and according to the concept of polar moment of inertia in material mechanics and superposition principle,the ...
