Advances and Perspectives in Graphene‐Based Quantum Dots Enabled Neuromorphic Devices

open access: yesAdvanced Science, EarlyView.
Graphene‐based QDs are zero‐dimensional carbon nanomaterials with pronounced quantum confinement and tunable electronic structures. Herein, we summarize their synthesis strategies and functionalization methods, and highlight their functional roles and operating mechanisms in devices, as well as recent advances in neuromorphic electronics. We anticipate

Molecularly Bridged Heterointerface Engineering: Designing Transparent, Wear‐Resistant, Hard yet Flexible Optoelectronic Protective Film

open access: yesAdvanced Science, EarlyView.
A molecular‐bridging heterogeneous interface engineering strategy is introduced to combine a polyhedral oligomeric silsesquioxane (POSS)‐based hard coating with a colorless polyimide (CPI)‐based flexible layer. The robust heterogeneous interface endows the integrated system with the superior properties of both layers and their synergistic ...

Short‐ and Long‐Term Outcomes of Subtotal Gastrectomy for Remnant Gastric Cancer: A Multicenter Study

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
This multicenter study compared subtotal versus completion gastrectomy for remnant gastric cancer. Subtotal gastrectomy was associated with shorter operative time and significantly less postoperative weight loss, with no difference in long‐term survival, suggesting it as a feasible surgical option without compromising oncologic outcomes.

Impact of Recanalization on Liver Hypertrophy after Portal Vein Embolization and the Role of Re‐Embolization

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
This retrospective study of 249 patients undergoing hepatectomy after right portal vein embolization (PVE) demonstrated that major recanalization–defined as recanalization more than one segment within the embolized liver–was associated with impaired regeneration of the future liver remnant (FLR).

Multiple Steady States in Homogeneous Azeotropic Distillation [PDF]

open access: yes, 1993
In this article we study multiple steady states in ternary homogeneous azeotropic distillation. We show that in the case of infinite reflux and an infinite number of trays one can construct bifurcation diagrams on physical grounds with the distillate ...
