Investigation and evaluation of palygorskite microstructure following acid pretreatment and its potential use as an adsorbent for copper.
Sci Rep
January 2025
Department of Chemical Engineering, University of Technology, Baghdad, Iraq.
Palygorskite exhibits distinctive morphological and textural characteristics due to its fibrous and micropore nature. This research experimentally investigates the microstructure of palygorskite and how acid treatment changes the fibrous shape and ability to adsorb. Acetic and hydrochloric acid were used to study the effect of acid on palygorskite fibrous morphology.

Autosomal hypophosphatemic rickets though a rare genetic disorder can lead to significant discomfort to the patient resulting in clinical deterioration and a poor quality of life. We describe a case of a 33-year-old woman G2P1001 at 6 weeks of gestation with complaints of myalgia and bony pains. Keeping her history of bony pains and fractures in mind, she was further evaluated.

Despite the growing interest in POV for FSO links, atmospheric turbulence (AT) induces phase distortions, resulting in POV-SK demodulation errors and degrading POV-SK FSO communication performance. The CViT demodulator utilizes conformal mapping to reshape the circular POV-SK patterns into rectangles, enabling more efficient feature learning.

Department of Urology, Ruby Hall Clinic, Pune, India.
Background: We aimed to evaluate and compare the rise in the temperature for the safety of the kidney parenchyma on firing the Holmium: Yttrium Aluminium Garnet laser and the Thulium Fiber Laser during laser lithotripsy in humans.
Method: We included 30 pre-stented patients with renal calculi undergoing Retrograde intra-renal surgery. They were randomized into two groups - 15 patients underwent holmium laser lithotripsy and 15 patients underwent TFL laser lithotripsy.
Experimental research on resource utilization of iron tailings powder in backfilling engineering.
Sci Rep
January 2025
Detong Intelligent Technology Co., Ltd, Xuchang, 461000, China.
The goaf formed by mining and other activities is prone to safety hazards. Preparing high-quality and low-cost solidified iron tailings powder (SITP) is an important way to ensure backfill quality and eliminate safety hazards. Using iron tailings powder near the goaf of in Shanxi, comparative experiments were conducted to evaluate the the flowability, stone rate, strength, and water stability of newly mixed SITP under different types and dosages of curing agent, and mixing methods.
