Rational Design of Metal–Organic Frameworks for Pancreatic Cancer Therapy: from Machine Learning Screening to In Vivo Efficacy

Advanced Materials, EarlyView.
This work explores the MOF landscape to select a single, optimal candidate for successfully delivering cancer drugs (gemcitabine, paclitaxel, SN‐38) into tough pancreatic tumors. Machine learning and simulations guide this search, demonstrating colloidal stability, excellent biocompatibility, cellular uptake, and sustained release.

Strategies for Controlling Emission Anisotropy in Lead Halide Perovskite Emitters for LED Outcoupling Enhancement

Advanced Materials, EarlyView.
The rise of lead halide perovskite semiconductors has enabled high‐performance LEDs with internal quantum efficiencies approaching 100%. In order to further enhance the external quantum efficiencies limited by light outcoupling effects, in this account, the strategies for reducing energy dissipation through the substrate, waveguide, and evanescent ...

Sustainable Smart Packaging from Protein Nanofibrils

Advanced Materials, EarlyView.
Smart packaging can extend shelf life and improve food quality monitoring. This study introduces a novel smart packaging solution using amyloid fibrils and red radish anthocyanins to monitor seafood spoilage. These findings show that these films effectively indicate shrimp freshness and possess high antibacterial and antioxidant properties, offering a ...

Convergence of Fourier series

, 2016
The main goal of this dissertation is to study the problem of convergence of Fourier series. This problem consists on, given a function f, deciding if its Fourier series converges to f. What conditions are necessary or sufficient for that to happen? What do we actually mean with convergence?
