Pseudothermoosmosis in a Composite Membrane System [PDF]

Polymer Journal, 1977
A composite membrane system, constituted by two cellulose membranes and an aqueous solution of poly(ethylene oxide) (liquid membrane), was used to investigate the transport phenomena occurring when a thermal difference was applied. At the steady state, pressures were measured (ca.

Molecularly Mixed Composite Membranes for Advanced Separation Processes.

Angewandte Chemie, 2019
Porous organic cages (POCs) are individual soluble, porous molecules. When fabricated into mixed-matrix membranes (MMMs), the soluble POC molecules have the potential to exhibit intimate molecular-level mixing with the polymer matrix.

Phase Angle as an Early Functional Biomarker of Cancer‐Related Fatigue in Pediatric Oncology: A Prospective Longitudinal Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric cancer remains a leading cause of morbidity and mortality worldwide, particularly in low‐and middle‐income countries. Cancer treatment may impair nutritional status, alter body composition, and exacerbate cancer‐related fatigue (CRF).

The Role of Chemotherapy in Pediatric Myoepithelial Carcinoma: A Systematic Review of the Literature

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Myoepithelial carcinoma (MEC) in pediatric patients is a rare and aggressive malignancy characterized by heterogeneous morphology and variable molecular features. The optimal role of chemotherapy remains unclear. We conducted a systematic review according to PRISMA 2020 guidelines to evaluate chemotherapy in pediatric and young‐adult patients ...
