Enhancing Droplet Spreading on a Hydrophobic Plant Surface by Surfactant/Cellulose Nanocrystal Complexes.

A surfactant is an efficient and common additive used to enhance the spreading of droplets on hydrophobic surfaces. However, a high surfactant concentration is required to achieve the desired performance, resulting in environmental pollution and increased costs. Additionally, the pesticide loading capacity of surfactants at low concentrations (below their critical micelle concentrations) is a concern.

Application Value of STOP-Bang Questionnaire in Predicting Abnormal Metabolites.

Objective: To evaluate the application value of STOP-Bang questionnaire (SBQ) in predicting abnormal metabolites.

Methods: Totally 121 patients were included into the study and filled the questionnaires, and their clinical data were collected at the same time. These patients were grouped according to the questionnaire scores.

Location or size? A finite element analysis study of necrotic lesion impact on femoral head collapse.

Background: The location and size of necrotic lesions are important factors for collapse, The preserved angles (PAs) are divided into anterior preserved angle (APA) and lateral preserved angle (LPA), which could accurately measure the location of necrosis lesion. We used them to evaluate the effect of the location and size of necrotic lesions on collapse by finite element analysis, to offer a framework for evaluating the prognosis of osteonecrosis of the femoral head (ONFH) in clinical settings.

Methods: 3 left hip models were constructed based on CT data.

Novel biopolymer-based active packaging material for chilled beef applications: Collagen peptide-astragaloside nanocomplexes incorporated into oxidized hydroxypropyl starch/chitosan films.

The present study intended to investigate the properties of collagen peptide (CP)-astragaloside (AG) nanocomplexes (CPANs) improved oxidized hydroxypropyl starch (OHS)/chitosan (CS) (OC) film and to explore the preservation of chilled beef. The results indicated that AG significantly enhanced the stability, antioxidant capacity, and antibacterial properties of CP through mechanisms like static quenching and hydrophobic interactions. The incorporation of CPANs improved thickness, swellability, and water vapor blocking, UV-blocking and mechanical properties, antioxidant and antibacterial activity of OC film.

Polydopamine-assisted ion-mediated hyaluronic acid grafting for effective construction of hemocompatible platform with cancer cell recognition.

Surfaces capable of specific biomolecule recognition are essential for cancer theranostics, biosensing, and tissue engineering. However, current grafting methods, critical for dictating the recognition efficiency and biocompatibility of biomaterials, especially hydrophilic polymers, struggle to balance high grafting density with ease of implementation. In pursuit of a simple, effective, and versatile solution, we introduced a polydopamine (PDA)-assisted Ca-mediated grafting strategy using hyaluronic acid (HA) as a model material.
