Article Abstract
This short article examines the microwave-assisted photolytic disinfection of aqueous solutions contaminated by Bacillus subtilis microorganisms using UV and vacuum-UV radiation emitted from a microwave discharge electrodeless lamp (MDEL), a device containing a Hg/Ar gas-fill that was proposed recently for use in Advanced Oxidation Processes (AOPs). Results of the disinfection are compared with those obtained from UV radiation emitted by a low-pressure electrode Hg lamp and by an excimer lamp. Also examined is the disinfection of B. subtilis aqueous media that contained Au3+ or Ni2+ ions, species often found in the treatment of electroplating wash wastewaters.

The release of toxic chemical dyes from the industrial effluent poses huge challenges for the environmental engineers to treat it. Azo dyes encompass the huge part of textile discharges which are difficult to degrade due to their complex chemical aromatic structures and due to the presence of strong bonds (-N=N-). Thus, the removal of a carcinogenic azo dye (i.
Multipactor, a vacuum discharge under microwave conditions triggered by secondary electron emission (SEE), plays a critical role in managing the power level of microwave devices. In this study, we developed a fluorocarbon-titanium composite film on aluminum by cosputtering polytetrafluoroethylene (PTFE) and titanium via a controlled temperature and sputtering power ratio (RF power for PTFE to DC power for Ti) to suppress the SEE of Al. The evolution of microtopography and chemical composition of the composite film was evaluated.
The margarine market is growing globally due to its lower cost, ease of availability, large-scale commercialization, and expanding market in the bakery and confectionary industries. Butter contains greater amounts of saturated fat and has been associated with cardiovascular diseases. The trans fats generated through the hydrogenation process have several adverse impacts on human health, such as the risk of atherosclerosis, coronary heart disease, postmenopausal breast cancer, vision and neurological system impairment, type II diabetes, and obesity.
Systemic air embolism, though rare, poses a significant risk as a complication of CT-guided lung lesion ablation. This condition often arises from the formation of a transient bronchovascular fistula, which can occur when a needle punctures the lung or accidentally breaches a pulmonary vein. In this report, we present a case involving acute cerebral infarction resulting from retrograde venous embolism linked to a fistula between the pleural cavity and pulmonary artery after pulmonary ablation.
Targeted microwave ablation (TMA) shows promise as a safe and effective treatment for localized prostate cancer, based on a pilot trial involving 11 patients.*
-
No severe complications were reported, and a significant percentage of patients exhibited no cancer in the treated area after follow-up, although new cancer foci were found in some cases.*
-
The study acknowledges limitations such as a small sample size, short follow-up duration, and absence of a comparison group, but supports the potential of TMA combined with fusion imaging for prostate cancer therapy.*
