AI Article Synopsis
- The study discusses the fabrication of FeCeB metallic glass ribbons and analyzes how their composition affects their glass forming ability (GFA) and magnetic properties.
- Results showed that increasing boron content enhances both GFA and the Curie temperature, with the maximum magnetic entropy change reaching 3.88 J/(kg × K) at 5 T when boron content is optimized.
- An amorphous composite was designed, displaying a significant average magnetic entropy change of about 3.29 J/(kg × K) in a specific temperature range, suggesting its potential use as an efficient refrigerant for domestic magnetic refrigeration systems.
Article Abstract
The novel FeCeB (x = 5, 6, 7) metallic glass (MG) ribbons were fabricated in this work. The compositional dependence of glass forming ability (GFA), magnetic and magnetocaloric properties of these ternary MGs, and the mechanism involved was investigated. The GFA and Curie temperature () of the MG ribbons were found to improve with the boron content, and the peak value of magnetic entropy change (-Δ) reaches a maximum of 3.88 J/(kg × K) under 5 T when x = 6. Based on the three results, we designed an amorphous composite that exhibits a table-shape magnetic entropy change (-Δ) profile with a rather high average -Δ (-Δ~3.29 J/(kg × K) under 5 T) from 282.5 K to 320 K, which makes it a potential candidate for the highly efficient refrigerant in a domestic magnetic refrigeration appliance.

Evaluation of anion exchange resin for sorption of selenium (IV) from aqueous solutions.
BMC Chem
January 2025
Nuclear Chemistry Department, Hot Laboratories Center, Egyptian Atomic Energy Authority, P.O. 13759, Cairo, Egypt.
In this work, selenium (IV) ions were adsorbed from aqueous solutions by the strongly basic anion exchange resin Amberlite IRA-400. The morphology of the resin before and after Se(IV) sorption was investigated using different techniques such as energy dispersive X-ray spectroscopy (EDX), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). To determine the ideal sorption conditions, a batch approach was used to examine the variables affecting Se(IV) sorption performance, including pH, shaking time, adsorbent dosage, initial metal ion concentration, and temperature.

Background: Epidemiological research on the association between heavy metals and congestive heart failure (CHF) in individuals with abnormal glucose metabolism is scarce. The study addresses this research gap by examining the link between exposure to heavy metals and the odds of CHF in a population with dysregulated glucose metabolism.
Method: This cross-sectional study includes 7326 patients with diabetes and prediabetes from the National Health and Nutrition Examination Survey from 2011 to 2018.
Exploring the potential of gemcitabine-metal-organic frameworks in combating pancreatic cancer under ketogenic conditions.
BMC Cancer
January 2025
Department of Biochemistry, School of Medicine, Iran University of Medical Sciences, Tehran, Iran.
Background: Inadequate treatment responses, chemotherapy resistance, significant heterogeneity, and lengthy treatment durations create an urgent need for new pancreatic cancer therapies. This study aims to investigate the effectiveness of gemcitabine-loaded nanoparticles enclosed in an organo-metallic framework under ketogenic conditions in inhibiting the growth of MIA-PaCa-2 cells.
Methods: Gemcitabine was encapsulated in Metal-organic frameworks (MOFs) and its morphology and size distribution were examined using transmission electron microscopy (TEM) and Dynamic light scattering (DLS) with further characterization including FTIR analysis.
Conditional Deletion of Gremlin-1 in Cathepsin K-expressing Mature Osteoclasts Altered the Skeletal Response to Calcium Depletion in Sex-Dependent Manner.

Musculoskeletal Disease Center (151), Jerry L. Pettis Memorial VA Medical Center, VA Loma Linda Healthcare System, 11201 Benton Street, Loma Linda, CA, 92357, USA.
This study assessed the novel concept that osteoclast-derived Grem1 has regulatory functions in the skeletal response to calcium stress using an osteoclastic Grem1 conditional knockout (cKO) mouse model. The calcium stress was initiated by feeding cKO mutants and wildtype (WT) littermates a calcium-deficient diet for 2 weeks. Deletion of Grem1 in mature osteoclasts did not affect developmental bone growth nor basal bone turnover.

Platinum nanoparticles (PtNPs) offer significant promise in cancer therapy by enhancing the therapeutic effects of platinum-based chemotherapies like cisplatin. These nanoparticles improve tumor targeting, reduce off-target effects, and help overcome drug resistance. PtNPs exert their anti-cancer effects primarily through the generation of reactive oxygen species (ROS), which induce oxidative stress and apoptosis in cancer cells.
