Self‐Supporting Graphene Foam for the Removal of Chlorine from Water

open access: yesAdvanced Materials Interfaces, EarlyView.
Graphene‐based porous materials are promising for sorption and catalysis but often require binders. This study presents a self‐supporting graphene foam made from graphene oxide and hydrazine vapor. Structural, mechanical, and functional analyses confirm its superior chlorine removal efficiency (97%) and reusability, outperforming activated carbon in ...

Antifouling Surface‐Attached Hydrogel Nanocoatings Redefined: Green Solvent‐Based, Degradable, and High‐Performance Protection Against Foulants

open access: yesAdvanced Materials Interfaces, EarlyView.
An ultrathin surface‐attached hydrogel coating is introduced that, unlike the best antifouling coatings so far, consists of hydrophilic, non‐charged, green solvent‐based monomers. It effectively renders the surfaces of medical devices stealth toward proteins, a clinical strain of MRSA and blood while offering on‐demand degradability to regenerate the ...

Advances in Petroleum Refining Processes

open access: yes, 2013
This chapter provides an overview of recent advances in several refinery processes, including fluid catalytic cracking (FCC), hydrotreatment of catalytically cracked gasoline to produce low-sulfur gasoline while preserving most of the olefins, isomerization of saturated n-olefins to avoid an octane number penalty, hydroprocessing of gas oil and vacuum ...

Polymer Nanogels with Albumin Reporting Interface Created Using RAFT Precipitation Polymerization for Disease Diagnosis and Food Testing

open access: yesAdvanced Materials Interfaces, EarlyView.
Herein, polymer nanogels with a reporting interface for albumin are synthesized through reversible addition–fragmentation chain transfer (RAFT) precipitation polymerization of di(ethylene glycol) methyl ether methacrylate and N,N’‐methylenebis(acrylamide) using a poly(2‐methacryloyloxyethyl phosphorylcholine) macro‐RAFT agent, followed by dansyl ...

Biocompatible Porphyrin Derivatives Electron Beam and Extreme Ultraviolet Photoresists: High Resolution and High Etch Resistance

open access: yesAdvanced Materials Interfaces, EarlyView.
Porphyrin derivatives are introduced for electron beams and extreme ultraviolet lithography. The lithographic performance of the novel CuTP‐4Epoxy photoresist is excellent, with a resolution of 18 nm in EBL and 20 nm in EUVL, and the photoresist also exhibits high etch resistance.

Exploring 3D Printing and Electrospinning Technologies for Advanced Porous Membrane Fabrication: A Review

open access: yesAdvanced Materials Technologies, EarlyView.
This paper contrasts electrospinning and 3D printing for porous membrane fabrication, evaluating their evolution, cost, resolution, mechanical traits, and scalability. While 3D printing excels in material diversity and industrial adaptability, electrospinning achieves finer resolution and thermal resilience.

The Role of Theoretical Calculations for INVEST Systems: Complementarity Between Theory and Experiments and Rationalization of the Results

open access: yesAdvanced Optical Materials, EarlyView.
Theoretical lessons are key for molecules presenting an inverted singlet‐triplet excited state (e.g. S1 and T1) energy difference. This perspective provides a snapshot of the role played by calculations in last years, not only to anticipate experimental findings but also for driving high‐throughput virtual screenings, as well as the main challenge to ...
