A determination by thin-layer chromatography of the chemical nature of the poison produced by the bryozoan lophopodella carteri (Hyatt) [PDF]

open access: yes, 1971
A study was undertaken to isolate and characterize by thin-layer chromatography the poisonous principle produced by the freshwater bryozoan, Lophopodella carteri (Hyatt). The bryozoan homogenate was divided into a lipid and non-lipid portion and each was

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

High‐throughput Photocatalytic Reactor With in Operando Characterisation for Fast Screening of Materials for the Photodegradation of Water‐Borne Pollutants

open access: yesAdvanced Materials Interfaces, EarlyView.
A novel fast‐screening photocatalytic reactor system (FaS‐PhoReS) using terrestrial sunlight is able to measure the in operando photodegradation of 32 samples at once, and does not suffer from the common problem of sample evaporation. Four photostable 12 dyes are used to investigate the photocatalytic performance of TiO2 and ZnO samples in both film ...

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.

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.

The Fabrication of Superhydrophobic Coatings Using Food‐Grade Wax Dispersions

open access: yesAdvanced Materials Interfaces, EarlyView.
A method is presented for creating superhydrophobic materials using a simple mixture of food‐grade wax and solvent. By varying the solubility and dispersibility of the wax as the solvent is replaced, superhydrophobic coatings can be achieved on different substrates using spray coating.
