Lattice Genome Framework for Regionally Tailored Component‐Level Multi‐Objective Design in Additive Manufacturing

open access: yesAdvanced Science, EarlyView.
A Lattice Genome framework links geometric and process “genes” to lattice “phenotypes” via correction‐calibrated high‐throughput simulations and a growing performance database. Genome‐driven retrieval and recombination of unit cells enables component‐level, regionally tailored multi‐objective design: stress fields are programmed under constant relative

Thermally Modulated Specular Phonon Transport in a High‐Debye‐Temperature Diamond Nanobeam

open access: yesAdvanced Science, EarlyView.
Thermal transport in single‐crystal diamond nanobeams is measured from 140 to 300 K using electro‐thermal micro‐suspended structures. The thermal conductivity shows an increasing deviation from Boltzmann transport predictions assuming fully diffuse boundary scattering at lower temperatures.

Stimulus‐Induced Self‐Reinforcement in Supramolecular Bamboo Plastics toward Mechanical Robustness and Programmable Shapeability

open access: yesAdvanced Science, EarlyView.
A self‐reinforcement strategy is reported for the fabrication of bamboo plastics utilizing ethanol to induce the supramolecular network reconstruction of cellulose and polyacrylamide molecules. These bamboo plastics exhibit high mechanical strength, excellent thermal stability, resistance to low temperatures, and controllable shapeability.

A Proof of the Factorization Forest Theorem

open access: yes, 2007
We show that for every homomorphism $\Gamma^+ \to S$ where $S$ is a finite semigroup there exists a factorization forest of height $\leq 3 \abs{S}$.

High‐Performance Recycling Biobased Photopolymers for 3D Printing

open access: yesAdvanced Science, EarlyView.
By using biobased phenols like eugenol, novel biobased photopolymers containing dissociative phenol‐carbamate bonds are designed for 3D printing. Meanwhile, a “mixed‐monomer assisted recycling” strategy is proposed to recycle the materials. The resulting materials not only achieve high‐performance and excellent chemical recyclability simultaneously ...
