Halloysite nanotubes (HNTs) are naturally occurring aluminosilicate minerals, known for their unique tubular structure, which have garnered significant interest for a wide range of applications. This study explores the morphological changes of HNTs when subjected to thermal treatment ranging from 25 °C to 1100 °C using a combination of experimental characterization techniques and molecular dynamics simulations. Techniques such as solid-state NMR (SSNMR), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Brunauer-Emmett-Teller (BET) surface area measurements, and Fourier Transform Infrared Spectroscopy (FT-IR) were employed to analyse the structural evolution.

To achieve optimal results, this paper utilizes diffusion models as the primary engine for these tasks. This paper presents two main contributions: (1) "Speaking the Language of Faces" (SLF): a flexible, modular, fusion-less and architecturally simple multimodal system.

The primary goal of this research was to investigate the presence of heavy metal pollutants and associated health risks in three distinct coastal cities, Jeddah, Al-Lith, and Al-Qunfudhah, located along Saudi Arabia's Red Sea coast. Forty-three soil samples were collected from different locations, heavy metals including Fe, Zn, Mn, Cu, Cd, and Pb were isolated, and analyzed using inductively coupled plasma optical emission spectroscopy.

From an industrial perspective, nickel (Ni)-supported catalysts have been deemed among the most suitable catalysts for DRM owing to their low cost and high activity compared to noble metals. However, a downside of nickel catalysts is their high susceptibility to deactivation due to coke formation and sintering at high temperatures.

Here, we present a combined experimental and computational study to clarify the effectiveness and molecular mechanism by which nickel nanoparticles, NiNPs, may enhance CO hydration in aqueous solutions. Contrary to previous literature, our kinetic experiments recording changes of pHs, conductivity, and dissolved carbon dioxide in solution reveal a minimal effect of the NiNPs in catalyzing CO hydration.
View Article and Find Full Text PDFOil and gas are only two industries that could change because of nanotechnology, a rapidly growing field. The chemical-enhanced oil recovery (CEOR) method uses chemicals to accelerate oil flow from reservoirs. New and enhanced CEOR compounds that are more efficient and eco-friendly can be created using nanotechnology.

Objective: To compare the safety, efficacy, and durability of ICI of onabotulinum toxin-A (BTX) in different doses (50 and 100 U) against placebo (saline) in the management of vasculogenic ED non-responding to pharmacological therapy (phosphodiesterase type 5 inhibitors or/and ICI of trimix).
Carbon dioxide scrubbing by aqueous amine solution is considered as a promising technology for post-combustion CO capture, while mitigating climate change. The lack of physicochemical details for this process, especially at the interface between the gas and the condensed phase, limits our capability in designing novel and more cost-effective scrubbing systems. Here, we present classical and molecular dynamics results on CO capture at the gas/amine solution interfaces using solvents of different polarities.

It suffers from salt stress during the first period of growth despite having to endure it after an advanced age. More than 30% of irrigated lands worldwide are destructively impacted by salt stress, which enormously influences the growth and productivity of several crops worldwide.

Patients And Methods: In all, 46 patients diagnosed with suspected NMIBC were included. All patients were diagnosed using ultrasonography, computed tomography, and diagnostic cystoscopy, and then underwent bipolar plasma kinetic enucleation of bladder tumour (PKEBT).
Purpose: To assess the outcome of transurethral plasmakinetic vaporization (PKVP) in the management of benign prostatic hyperplasia (BPH).
Patients And Methods: From August 2010 to May 2012, 60 patients with obstructive LUTS due to BPH were included in the study. All patients were evaluated by International Prostate Symptom Score (IPSS), general examination, digital rectal examination, PSA, routine laboratory examinations, pelvi-abdominal ultrasound, trans-rectal ultrasound, and uroflowmetry.
Introduction: To assess the feasibility of single-incision laparoscopic surgery (SILS) in some urological surgeries.
Material And Methods: This prospective study was conducted on 40 patients (27 males and 13 females) from January 2010 to June 2011. Six procedures were done, SILS renal cyst decortication (n = 10), SILS varicocelectomy (n = 10), SILS orchiopexy (n = 10), SILS nephrectomy (n = 3), SILS pyelolithtomy (n = 6) and SILS adrenalectomy (n = 1).
