The introduction of a rubidium fluoride post deposition treatment (RbF-PDT) for Cu(In,Ga)Se<sub>2</sub> (CIGS) absorber layers has led to a record efficiency up to 22.6% for thin-film solar cell technology. In the present work, high efficiency CIGS samples with RbF-PDT have been investigated by atom probe tomography (APT) to reveal the atomic distribution of all alkali elements present in CIGS layers and compared with non-treated samples.

Commonly used sample introduction systems for inductively coupled plasma mass spectrometry (ICP-MS) are generally not well-suited for single particle ICP-MS (spICP-MS) applications due to their high sample requirements and low efficiency. In this study, the first completely 3D-printed, polymer SIS was developed to facilitate spICP-MS analysis. The system is based on a microconcentric pneumatic nebulizer and a single-pass spray chamber with an additional sheath gas flow to further facilitate the transport of larger droplets or particles.

They have high therapeutic efficiency and satisfactory consumer properties due to the presence of two phases at once, are able to provide improved diffusion of active pharmaceutical ingredients (API), maintain optimal concentration in the area of application, have high adhesive properties, which allows them to

Abstract Abstract 3207 Introduction and Aim: Iron is an essential metal in the body, but its overload causes various organ damages through free radical productions. When the balance of iron metabolism is collapsesed by a prolonged transfusion and iron medication etc, transferrin (Tf) will be saturated and non-Tf bound iron (NTBI) will appear in the serum. It has been reported that NTBI relates to oxidant stress and cellular damages. Concerning the measurement of NTBI in blood, there are several problems including the expensive consumables and the long time to measure. Moreover, the method of m

Abstract Introduction: Cell-free DNA (cfDNA) extracted from urine has created new opportunities in non-invasive cancer diagnostics, particularly for prostate cancer. Detecting cfDNA in urine can be challenging due to its inherently low concentration. Increasing the input volume of urine addresses this limitation, enhancing the sensitivity of cfDNA detection. This study explores the benefit of collecting larger volumes of urine spiked with a TP53 mutation and the corresponding increase in assay sensitivity for early prostate cancer diagnosis and monitoring. Methods: Pooled urine from healthy do

Cytology is known to be a highly effective method of diagnosis of lung metastases. The cytomorphological criteria for lung metastases of malignant melanoma are known and described in the literature, but are few in number and there are some objective difficulties in the differential diagnosis of malignant melanoma metastases of other lung lesions. This paper presents a clinical and morphological case of MM metastasis and demonstrates the high efficiency of the traditional (classical) cytological method in its diagnosis according to established the cytomorphological criteria, which complements t

Introduction. Studies have shown that the style of each person's activity largely depends on the type of higher nervous activity entering the structure of his temperament. The temperament of an individual is considered innate, because it is a psychic property that does not lend itself to pedagogical correction and volitional regulation. Since the type of temperament affects the overall activity of the person, the idea arose to investigate the possibility of its influence on the work of the maxillofacial apparatus of young, healthy people. The aim of the work is to analyze the degre

However, soil spectra are very sensitive to soil moisture content, which is a crucial factor affecting the accuracy of soil nutrient composition prediction. In response to this issue, the goal of this study is to identify the best model to correct the effect of soil moisture for predicting soil total nitrogen by near-infrared spectroscopy.
