Abstract As a potential substitute for antibiotics, cadmium sulfide and zinc oxide nano-particles (CdS and ZnO NPs) were created using laser ablation and a straightforward chemical process, respectively. Target of cadmium sulfide, deionized water, zinc nitrate, and sodium hydroxide were used as precursors. Different characterization techniques were used to characterize the CdS and ZnO NPs. X-ray diffraction was used to confirm that the CdS and ZnO had polycrystalline structures with average crystalline sizes of 54.16 nm and 29.23 nm, respectively. The ZnO particles were densely packed 2D curved nanopetals with a diameter of 51.65 nm, whereas… More >

Abstract Background: Aquablation is a robotic-assisted, water jet-based transurethral therapy for benign prostatic hyperplasia (BPH). Concerns about postoperative hematuria led to the practice of limited transurethral resection (TUR) with cauterization. This study aimed to assess the impact of tranexamic acid (TXA) on hematuria outcomes when combined with limited TUR after Aquablation. Methods: We retrospectively analyzed men undergoing Aquablation at our institution (October 2020–July 2024). Demographic, prostate, surgical, and hematuria outcomes were extracted from electronic medical records. Kruskal-Wallis test compared medians. Results: Of 131 patients, 113 (86%) had limited TUR; 31 (27%) received 1 g TXA perioperatively. TXA… More >

Abstract Flow boiling in open microchannels offers highly efficient heat transfer performance and has attracted increasing attention in the fields of heat transfer and thermal management of electronic devices in recent years. However, the continuous rise in power density of electronic components imposes more stringent requirements on the heat transfer capability of microchannel flow boiling. HFE-7100, a dielectric coolant with favorable thermophysical properties, has become a focal point of research for enhancing flow boiling performance in open microchannels. The flow boiling heat transfer performance of HFE-7100 was investigated in this study by fabricating micro-nano composite structures… More >

Abstract Er³⁺-ions doped SiO₂-ZnO-Na₂O thin films were fabricated using ultrafast laser plasma doping (ULPD) techniques under different ambient atmospheres; vacuum, nitrogen, oxygen and argon gas. The thickness of the layer produced depends on the ambient atmosphere during fabrication. The layer fabricated under a vacuum is the thinnest among all of the samples. In addition, the surface layer for the sample fabricated under a vacuum environment seems to be relatively smoother compared with those of the others. XRD patterns show that all samples are in a mixed amorphous-crystalline phase. All the Raman spectra exhibited a similar pattern, except More >

Abstract Zinc telluride (ZnTe) nanocrystals (NCs) have generated the interest of researchers as an electrode material in hybrid light emitting devices (HLEDs) due to its potentially high capacity. However, due to the restricted fundamental charging capacity of the electrode materials, the available energy of existing nanomaterial light emitting devices remains enough for a wide range of applications. In this research, ZnTe nanocrystals were synthesized using Nd: YAG laser at energy 600 mJ by 150 pulse number to form a battery device out of ITO/ZnTe/TPD/Ni. The spectra of the ZnTe NCs were assessed using ultraviolet-visible (UV-VIS) and More >

Abstract Using a laser energy of no more than 600 mJ/pulse and a maximum of 500 pulses, this work selectively produced pure copper, indium, gallium, and selenide (CIGS) NPs using a laser ablation method with distilled water and n-type porous silicon prepared by the photoelectron etching method. The material exhibits quantum dot behavior, according to experimental investigations. Porous silicone bases were produced using a current density of 10 mA/cm2 and an etching time of 15 min. Tests XRD, SEM, AFM, FTIR, UV, PL were conducted for the porous silicone and CIGS NPs to ensure that each More >

Abstract This work presents the synthesis and characterization of Homophase CdS and Heterophase Fe/CdS nanoparticles prepared by pulsed laser ablation (PLA) in water and methanol using nanosecond duration Nd:YAG laser. The morphology, the crystalline state, and the structure of the products were examined by performing SEM, XRD, and FTIR measurements, respectively. The results showed the transformation of the crystalline phase and changing the clustering size of CdS nanoparticles when performing PLA in methanol and water. Fe/CdS Heterojunctions were obtained in both liquids. The presence of Fe nanoparticle imposed another phase transformation and significantly improved the aggregation More >

Abstract Introduction: Partial gland ablation (PGA) using high intensity focal ultrasound (HIFU) is an alternative to active surveillance for low to intermediate risk localized prostate cancer. This pilot study assessed quality of life (QoL) outcomes during the implementation of PGA HIFU at our institution.
Materials and methods: We prospectively enrolled 25 men with a diagnosis of localized low/intermediate risk prostate cancer who elected to undergo PGA-HIFU in a pilot study at our institution between 2013 and 2016. Patients underwent pre-treatment mpMRI and transrectal ultrasound-guided biopsies. The primary endpoints were impact on patient-reported functional outcomes (erectile, urinary function, QoL)… More >

Abstract Standard treatment approaches for localized prostate cancer remain limited to active surveillance, radiotherapy, and radical prostatectomy. We present a case of transition zone prostate cancer that was treated with holmium laser enucleation of the prostate, a procedure that is normally reserved for the management of benign prostatic hyperplasia.

Abstract Introduction: Local disease recurrence following focal therapy (FT) for prostate cancer may be due to failure to eradicate focal disease or development of disease in the untreated prostate (in- and out-of-field recurrences). Several studies suggest in-field contrast enhancement (CE) on post treatment multi-parametric (mp) MRI between 6-12 months following FT indicates residual disease. The present study assesses the incidence and oncologic implications of early CE observed following primary partial gland cryoablation (PPGCA).
Material and methods: The surveillance protocol for men enrolled in our prospective outcomes study following PPGCA included mpMRI at 6-12 months, 2 years, 3.5 years,… More >
