Self‐Cascade Catalytic Reaction–Assisted Apoptosis/Calcicoptosis/Ferroptosis Induction with Microsphere‐Aggregated Hydrogels in Triple‐Negative Breast Cancer Therapy

open access: yesAdvanced Functional Materials, EarlyView.
Hyaluronic acid‐dopamine‐based intra‐crosslinked microsphere including cisplatin (HPC MS) is fabricated by spray‐drying and calcium/iron ions are introduced for interparticle crosslinking. Designed microsphere‐aggregated hydrogel (MAH) system including cisplatin/CaO2/FeSO4 can provide apoptosis/calcicoptosis/ferroptosis‐mediated chemo/cascade ...

Thin Layer Chromatography of Marihuana [PDF]

open access: yesJournal of AOAC INTERNATIONAL, 1972
The various TLC methods employed in the separation and identification of Cannabis products to date are reviewed. Two solvent systems are recommended for rapid identification of marihuana: multiple development, semiquantitatiom, and wedge and loose-layer chromatographic techniques are discussed.

Polymer Brush Growth by Surface‐Initiated Ring‐Opening Polymerization from a Cross‐Linked Polymer Thin Film

open access: yesAdvanced Functional Materials, EarlyView.
A stable cross‐linked ultra‐thin polymer coating for surface‐initiated ring‐opening polymerization (SI‐ROP) of hexamethylcyclotrisiloxane and ε‐caprolactone for growth of high grafting density poly(dimethyl siloxane) and poly(caprolactone) brushes is developed.

Rational Design of Photo-Electrochemical Hybrid Devices based on Graphene and Chlamydomonas reinhardtii Light-Harvesting Proteins [PDF]

open access: yesarXiv, 2020
Dye-sensitized solar cells (DSSCs) have been highlighted as the promising alternative to generate clean energy based on low pay-back time materials. These devices have been designed to mimic solar energy conversion processes from photosynthetic organisms (the most efficient energy transduction phenomenon observed in nature) with the aid of low-cost ...

High‐Fidelity Directed Self‐Assembly Using Higher‐χ Polystyrene‐Block‐Poly(Methyl Methacrylate) Derivatives for Dislocation‐Free Sub‐10 nm Features

open access: yesAdvanced Functional Materials, EarlyView.
The relationship between primary polymer structure and pattern quality in the directed self‐assembly of chemically modified polystyrene‐block‐poly(methyl methacrylate) derivatives is explored. The perpendicular lamellae are aligned, with a periodicity below 20 nm. No parallel orientations or dislocations form, and line patterns are well defined over an
