Electroosmosis and electrochromatography in narrow bore packed capillaries. [PDF]

open access: yes, 1990
Electroosmosis, the electrically induced flow of liquid, can be used as an alternative to pressure driven flow in liquid chromatography. Consideration of the physical nature of this type of flow suggests that less peak dispersion should result than with

Sphere Packing on a Quantum Computer for Chromatography Modeling [PDF]

open access: yesarXiv
Column chromatography is an important process in downstream biopharmaceutical manufacturing that enables high-selectivity separation of proteins through various modalities, such as affinity, ion exchange, hydrophobic interactions, or a combination of the aforementioned modes.

Toward Personalized Stationary Chromatography Phases: Equipping Commercial Silica Phases with Selected Peptide‐Based Binding Domains to Tailor Affinity

open access: yesAdvanced Materials Interfaces, EarlyView.
The 7‐mer peptide motifs QFFLFFQ, QFFEFFQ, and QFQQSFF, known as good, medium, and poor binders for the photosensitizers m‐THPC and Chlorin E6 are covalently immobilized on commercial amino‐functionalized silica particles by inverse electron‐demand Diels‐Alder ligation.

Single‐Crystal Organic Field‐Effect Transistors Based on 5,15‐Bisaryl‐Tetrabenzoporphyrins: Synthesis, Structure, and Charge Transport Properties

open access: yesAdvanced Materials Interfaces, EarlyView.
This study explores single‐crystal organic field‐effect transistors (SC‐OFETs) based on 5,15‐bisaryl‐tetrabenzoporphyrin derivatives. It highlights the impact of meso‐substituted groups on molecular packing and charge transport. Among the derivatives, C8Ph‐BP achieves the highest hole mobility (1.64 cm2 V−¹ s−¹) due to enhanced π‐stacking with ...

An Anticoagulant Coating Based on a Block Phosphocholine Copolymer for Potential Applications in Blood Contact Devices

open access: yesAdvanced Materials Interfaces, EarlyView.
Anticoagulant properties are critical for blood‐compatible materials, and anticoagulant coatings are a common key issue for blood‐contacting medical devices. In this study, a block copolymer poly(2‐methacrylenoxyethyl phosphocholine‐b‐glycidyl) (PMPC‐b‐GMA) is synthesized, using reversible addition‐fragmentation chain transfer polymerization (RAFT) and

Durable Bio‐Based Nanocomposite Coating on Urinary Catheters Prevents Early‐Stage CAUTI‐Associated Pathogenicity

open access: yesAdvanced Materials Interfaces, EarlyView.
A stable bio‐based nanocomposite coating for urinary catheters is developed using a simple, environmentally‐friendly sonochemical process. The coating, integrating antimicrobial, antibiofilm, and antioxidant properties, effectively tackled multiple early‐stage pathogenic factors associated with catheter‐associated urinary tract infections.

Preliminary Survey of Aflatoxins in Mashhad’s Roasted Red Skin Peanut Kernels during February to May 2016

open access: yesJournal of Community Health Research, 2018
Introduction: Aflatoxins (AFs) are a group of mycotoxins created as metabolic items for the most part by three types of Aspergillus including Aspergillus flavus, Aspergillus parasiticus and the uncommon Aspergillus nomius.

Understanding the Role of Copper Oxidation State on a TiO2/ZSM‐5 Catalyst for Photocatalytic CO2 Reduction to Methanol

open access: yesAdvanced Materials Interfaces, EarlyView.
The influence of copper oxidation states on TiO₂/ZSM‐5 catalysts is investigated for photocatalytic CO2 reduction to methanol. A Cuδ⁺‐modified Ti₂/ZSM‐5 catalyst (CTZ‐1) exhibits superior activity due to enhanced electronhole separation, the presence of Ti3⁺, and a core–shell structure.
