On the ring structure of K∗ for discrete groups
The author considers a discrete group \(\Gamma\) of finite cohomological dimension and finds a rational splitting for its classifying space. This is based on the multiplicative formula due to T.~tom Dieck describing a rational splitting for \(G\)-equivariant \(K\)-theory for groups of considered type.

This work reports the self‐assembly of a pyrene derivative into two distinct nanostructures and their application in visible‐light photocatalysis. The two nanostructures exhibit completely different yet complementary photocatalytic activities, promoting either H2 or H2O2 evolution.

This study presents a capacitive hydrogen sensor with a simple structure and process. Sonication‐induced Pd nanogaps modulate the effective electrode area in response to hydrogen concentration, resulting in capacitance changes within a range predefined by physical parameters.

Symplectic Structure of Discrete Hamiltonian Systems
The author considers the discrete Hamiltonian system \[ \Delta x(t)= H_u(t,x(t+1),u(t)), \qquad \Delta u(t)= -H_x(t,x(t+1),u(t)), \tag{1} \] where \(x,u\in \mathbb R^d\), \(H(t,x,u)\) is the corresponding real Hamiltonian function having continuous derivatives in \(x\), \(u\).

Conformally Perforated Shellular Metamaterials with Tunable Thermomechanical and Acoustic Properties
This study introduces Conformally Perforated Shellular Metamaterials (CPSMs), which overcome TPMS design limitations by mapping 2D cellular layouts onto 3D surfaces. CPSMs exhibit enhanced elastic stiffness, thermal conductivity, and acoustic performance compared to intact P‐type shellulars, demonstrating their potential as multifunctional ...
