A Dynamic 3D Human Liver Sinusoid Model for Mechanistic Interrogation of Fontan‐Associated Liver Disease

open access: yesAdvanced Science, EarlyView.
This study presents a perfusable 3D bioengineered liver sinusoid platform that integrates biofabrication, 3D cell culture, controlled hemodynamics, and multiparametric characterization to model Fontan‐associated liver disease. By decoupling pressure and hypoxia effects, the system reveals early mechanobiological and profibrotic responses under ...

High‐Throughput Data Generation and Transfer Learning Enabled Microstructure‐Property Integrated Design of Nickel‐Based Powder Metallurgy Superalloy

open access: yesAdvanced Science, EarlyView.
An integrated transfer learning framework integrates CALPHAD simulations, diffusion‐multiple experiments, and literature data to predict long‐term microstructural stability and short‐term mechanical properties of Ni‐based powder metallurgy superalloys. Based on these model predictions, a high‐performance, low‐density alloy, USTB‐PM750, is designed from

Controlled Moderate Interfacial Reaction Facilitates High‐Strength Low‐Resistivity Barrier Layer for Half‐Heusler Thermoelectrics

open access: yesAdvanced Science, EarlyView.
The barrier layer is designed comprehensively by thermal expansion coefficient and interfacial reaction energy to yield a controlled interfacial reaction. Ultimately, the Co25Fe50Ni25/half‐Heusler joint simultaneously achieves low contact resistivity and high bonding strength.

Electron-Beam Melting and Reuse of Metallic Materials

Metal Science and Heat Treatment, 2020
We study the processes and mechanisms of electron-beam melting (EBM) used in the production of high-purity metals. We formulate the requirements that should be imposed on the EBM parameters for the production of high-quality materials and proposed some optimal modes.

Modelling and simulation of electron beam melting

Production Engineering, 2009
In recent years, the scientific and industrial relevance of additive layer manufacturing (ALM) has grown. In the metal area of ALM, the capacity of laser technologies is noticeably limited. This is mainly due to an inertial beam deflection device, which is also referred to as a mirror galvanometer.
