The effects of the disinfectants NaClO and calcinated calcium on the food-borne pathogens Staphylococcus aureus, Escherichia coli O157:H7, and Salmonella spp. attached to shredded cabbage leaves were examined. After these bacteria were attached to shredded leaves for 1 h, the leaves were treated with NaClO and/or calcinated calcium. About 2.6-log and 3.5-log reductions of E. coli O157 were achieved by treatment with NaClO (100 ppm, pH 6.0, 10 min) and calcinated calcium (0.1%, 20 min), respectively. The combination of 100 ppm NaClO and 0.1% calcinated calcium resulted in a 3- to 4-log reduction in the pathogen populations without apparent deteriorative effects. The bacterial numbers in the treated cabbage did not increase during storage at 4 degrees C. However, sensory evaluation including appearance and flavor indicated that the quality of the treated cabbage declined during storage. In conclusion, the combination of NaClO and calcinated calcium was useful in treatment before eating.

Introduction: This study compares the quality of hydroxyapatite in Anadara granosa waste and laying chicken eggshell waste to commercial synthetic hydroxyapatite.
Material And Methods: This experimental research included 27 samples of hydroxyapatite derived from clam shell waste (CSW-HAP), hydroxyapatite derived from eggshell waste (ESW-HAP), and commercial synthetic hydroxyapatite, with nine samples of each. The calcination method was used to process clam shell waste and eggshell waste into hydroxyapatite, which was then compared with synthetic hydroxyapatite from Bongros® for calcium and phosphate content.

Near-infrared (NIR) persistent luminescence nanoparticles (PLNPs) have significant potential in diagnostic and therapeutic applications owing to their unique persistent luminescence (PersL). However, obtaining high-performance NIR PLNPs remains challenging because of the limitations of current synthesis methods. Herein, we introduce a spatial confinement growth strategy for synthesizing high-performance NIR PLNPs using hollow mesoporous silica (hmSiO).

Phosphogypsum (PG) is a phosphate fertiliser by-product. This by-product has a low level of utilisation. Calcium sulphate is dominated in PG similar to gypsum and, therefore, has good binding properties (similar to natural gypsum).

To inhibit eutrophication caused by endogenous pollutants release, the experiment explored the efficiency and mechanism of the synchronous control of nitrogen (N) and phosphorus (P) release from sediments in shallow lakes under wind disturbance by modified Ca/Al-based sludge (MS) and modified zeolite (MZ). High-temperature calcination and NaCl impregnation increased the pore volume of MS and Na content of MZ, and the adsorption capacity of MS for PO-P and MZ for NH-N was as high as 42.01 and 20.

Bone loss in the alveolar ridge is a factor widely studied by dentists in implant surgeries, as it poses a major challenge for aesthetic and functional recovery in patients with large maxillary bone defects. Synthetic biomaterials function as grafts designed to replace and remodel bone tissue. Calcium phosphate is a biomaterial that has good properties such as biocompatibility and bioactivity, making it a reference in bone replacement treatments.
