Facile Construction Engineering of PrO@C with Efficient Photocatalytic Activity.

In this study, facile construction engineering of PrO@C with efficient photocatalytic activity was established. Taking advantage of the flocculation of Pr in the base medium, acid red 14 (AR14) was flocculated together with Pr(OH) precipitate, in which Pr(OH) and AR14 mixed highly uniformly. Calcinated at high temperature in N2, a novel PrO@C was successfully synthesized.

Remote Assisted Home Dressing vs. Outpatient Medication of Central Venous Catheter (Peripherally Inserted Central Venous Catheter): Clinical Trial A.R.C.O. (Remote Assistance Oncology Caregiver).

Background: Management of PICC dressing can be performed at home by the patient through adequate training and telenursing. This trial verifies that the incidence of catheter-related complications in home patients, assisted by telenursing, is not greater than that observed in outpatients.

Methods: This clinical trial is composed of 72 patients with malignant tumors who underwent long-term chemotherapy with PICC insertion.

Highly Cytocompatible Polylactic Acid Based Electrospun Microfibers Loaded with Silver Nanoparticles Generated onto Chestnut Shell Lignin for Targeted Antibacterial Activity and Antioxidant Action.

Electrospun (e-spun) fibers are generally regarded as powerful tools for cell growth in tissue regeneration applications, and the possibility of imparting functional properties to these materials represents an increasingly pursued goal. We report herein the preparation of hybrid materials in which an e-spun d,l-polylactic acid matrix, to which chitosan or crystalline nanocellulose was added to improve hydrophilicity, was loaded with different amounts of silver(0) nanoparticles (AgNP) generated onto chestnut shell lignin (CSL) (AgNP@CSL). A solvent-free mechanochemical method was used for efficient (85% of the theoretical value by XRD analysis) Ag(0) production from the reduction of AgNO by lignin.

Combining the Potent Reducing Properties of Pecan Nutshell with a Solvent-Free Mechanochemical Approach for Synthesizing High Ag Content-Silver Nanoparticles: An Eco-Friendly Route to an Efficient Multifunctional Photocatalytic, Antibacterial, and Antioxidant Material.

A straightforward, low-cost, and scalable solid-state mechanochemical protocol for the synthesis of silver nanoparticles (AgNP) based on the use of the highly reducing agri-food by-product pecan nutshell (PNS) is reported herein. Under optimized conditions (180 min, 800 rpm, PNS/AgNO ratio = 55/45 /), a complete reduction in silver ions was achieved, leading to a material containing ca. 36% / Ag (X-ray diffraction analysis).

Use of Zeolites in the Capture and Storage of Thermal Energy by Water Desorption-Adsorption Cycles.

In this work, four zeolite-bearing materials (three naturally occurring and one of synthetic origin) were considered for thermal energy capture and storage. Such materials can store thermal energy as heat of desorption of the water present therein, heat that is given back when water vapor is allowed to be re-adsorbed by zeolites. This study was carried out by determining the loss of water after different activation thermal treatments, the water adsorption kinetics and isotherm after an activation step of the zeolites, the intergranular and intragranular porosity, and the thermal conductivity of the zeolite-bearing materials.
