Summary: This paper investigated the application of photoacoustic spectroscopy to estimate total phenolics content in raw propolis collected in the state of Paran ' a, Brazil. The absorption spectrum from 260 nm to 650 nm indicated three main bands related to different components. GLSW was found to successfully discriminate propolis samples from different geographical origins. The iPLS method of photoacoustic spectroscopy and phenolic content showed accurate estimation of phenolics level in raw propolis.

Summary: Photoacoustic (PA) imaging has gained popularity in the past decade due to its successful application in both preclinical and clinical settings. It has notable features such as non-ionizing, cost-effective, easily deployable, and high resolution for assessing tissue characteristics and therapeutic efficacy. PA imaging can be integrated with ultrasound systems to co-register and cross-reference various imaging features. This review discusses the applications of PA imaging with endogenous contrast in clinically relevant areas.

Summary: One major source of environmental pollution is industrial effluents, especially zinc pollutants in wastewater. Continuous and effective monitoring of zinc in industrial effluents is essential for safeguarding water quality. However, real-life environmental data often do not follow normal distribution, making it challenging to use traditional statistical monitoring techniques. This study proposes an optimal X scheme for monitoring non-normal zinc data in industrial effluents, minimizing costs and ensuring the monitoring scheme's accuracy.

Summary: Pulsed laser ablation has been shown to significantly reduce particle size of drugs, improving dissolution rate and bioavailability. This technique was successfully applied to meloxicam, a drug with poor water solubility, yielding promising results in both air and distilled water environments. The formation of nanoaggregates during laser ablation in air, a phenomenon rarely studied before, was also observed.

Summary: This study investigates the use of laser ablation as a technique for generating soot with high elemental carbon content, similar to diesel or atmospheric soot. The characteristics of the generated particles are compared to other commonly used techniques. The results show significant differences in physicochemical features between different combustion soot and soot generated by different excitation mechanisms. However, the laser ablation technique proves to be a useful tool due to its ability to independently adjust the physical characteristics of the generated soot particles.
