SiC/Si ceramic hollow fibres: A new approach to Chlorella vulgaris biomass harvesting

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Efficient harvesting of microalgae is a critical challenge for the viability of biorefineries, requiring technologies that combine high selectivity, low cost, and scalability. The current work evaluated the performance of an asymmetric hollow fibre ceramic membrane (HF‐SiC70Si30), fabricated by phase inversion and sintered at 1250°C, in the ...

El efecto coagulante de la digital

Revista de la Facultad de Medicina, 1946
Se lleva a cabo un trabajo para determinar el efecto coagulante de las dosis terapéuticas de digital, empleando las técnicas de Howell, de Lee y White, y de Quick. No se encontró modificación de la protrombina en los casos observados con el método de Howell. Se encontró aceleración del tiempo de protrombina -método de Quick - en 5 de 6 casos.

Release of multicomponent pheromones from porous fibres

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Surface engineering empowers a polymer exclusion net to serve dual functions: physical exclusion and pheromonal release, allowing for pest control in agricultural crops. In previous work, a net woven from porous fibres releasing simple, single‐component alarm pheromones showed promising results in field tests.

Novel Zwitterionic Polydopamine Nanofiller‐Reinforced Hybrid Membranes With Superior Antifouling Performance for Wastewater Treatment

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work reports one‐pot synthesized novel zwitterionic polydopamine‐silica (ZSiPDA) nanofillers for fabricating PES hybrid ultrafiltration membranes with enhanced hydrophilicity, permeability, and antifouling performance. The optimized membrane achieved over 91% humic acid removal and showed strong potential for municipal wastewater treatment.

Stereo‐electroencephalography–guided cross‐electrode radiofrequency thermocoagulation in focal epilepsy: A review of current methodologies and outcomes

Epilepsia, EarlyView.
Abstract Advances in stereo‐electroencephalography–guided radiofrequency thermocoagulation (SEEG‐guided RFTC) have led to the development of cross‐electrode RFTC, which has been shown to result in significantly larger lesions and higher seizure‐freedom rates compared to standard RFTC methods.
