Giant branch systems: surveys and populations [PDF]

open access: yesarXiv
Despite the recent discoveries of planets orbiting stars at all evolutionary stages, the evolution of planetary systems remains poorly understood. Studying planetary systems around red giant branch stars can reveal how main sequence planetary systems can change and evolve into white dwarf systems over time.

Two Steps Li Ion Storage Mechanism in Ruddlesden–Popper Li2La2Ti3O10

open access: yesAdvanced Science, EarlyView.
This study demonstrates the performance of Ruddlesden‐Popper Li₂La₂Ti₃O₁₀ as an anode material for lithium‐ion batteries, achieving 170 mAh·g⁻¹ capacity with two voltage plateaus from lithium ions stored at different sites. Unique unit cell changes during lithiation ensure high structural stability, leading to 88% capacity retention after 1000 cycles ...

Efficient and Specific PDGFRβ‐Targeting Dual‐Mode T1‐T2 MRI Nanoprobe for Early Diagnosis of Non‐Alcoholic Fatty Liver

open access: yesAdvanced Science, EarlyView.
The Fe3O4/Gd@BSA‐pPB nanoprobe leverages biomimetic mineralization and targets hepatic stellate cells (HSCs) through PDGFRβ, offering superior enrichment in fibrotic regions. This targeted delivery overcomes biological barriers, enhancing both the accuracy and sensitivity of MRI imaging at early disease stages.

Sustainable decision making for chemical process systems via dimensionality reduction of many objective problems

open access: yesAIChE Journal, Volume 69, Issue 2, February 2023., 2023
Abstract Recent global events and the rise of sustainable investing have made clear that the chemical and energy industry must consider sustainability goals beyond profit maximization to remain competitive. Multiobjective optimization provides an ideal framework for analyzing sustainability tradeoffs, but when four or more objectives are considered ...
