This paper presents colorimetric determination of Hg(II) based on MoS2 nanosheets with peroxidase mimics activity. The structure of the this sensor by the peroxidase mimic activity material of MoS2 nanosheets with TMB (Tetramethylbenzidine) solution, the colorimetric detection target of Hg(II) is determined by on-off mechanism using biomolecule of cysteine. The MoS2 nanosheets evaluated by X-ray diffraction, FT-IR and SEM image, confirms formation of a flower like structure.

Abstract:

This study explores the drivers and evolution of the shadow economy in Bosnia and Herzegovina—a transitional, post-conflict country facing persistent institutional fragility. Using the Multiple Indicators and Multiple Causes (MIMIC) model, an extension of Structural Equation Modeling, the paper estimates the size and dynamics of the shadow economy from 1996 to 2022. The model integrates macroeconomic indicators (employment rate, GDP per capita, tax revenues) and institutional variables (rule of law, control of corruption), with data primarily sourced from the World Bank.

Abstract:

Micro-/nano-structured scaffolds with a weight composition of 46.6% α-tricalcium phosphate (α-TCP)—53.4% silicocarnotite (SC) were synthesized by the polymer replica method. The scanning electron microscopy (SEM) analysis of the scaffolds and natural cancellous bone was performed for comparison purposes. Scaffolds were obtained at three cooling rates via the eutectoid temperature (50 °C/h, 16.5 °C/h, 5.5 °C/h), which allowed the surface nanostructure and mechanical strength to be controlled. Surface nanostructures were characterized by transmission electron microscopy (TEM) and Raman analysis.

Abstract:

This paper proposes a new model of measuring a latent variable, stock market manipulation. The model bears close resemblance with the literature on economic well-being. It interprets the manipulation of a stock as a latent variable, in the form of a multiple indicators and multiple causes (MIMIC) model. This approach exploits systematic relations between various indicators of manipulation and between manipulation and multiple causes, which allows it to identify the determinants of manipulation and an index of manipulation simultaneously. The main reason of stock market manipulation comes from

Abstract:

The combination of 1D nanotubes with 0D nanoparticles to integrate a nanocomposite structure has attracted increasing research interest, while the interfacial interaction plays an important role in such composites. This paper presents a facile and universal approach for the fabrication of hierarchical NP-NT nanocomposites with improved photocatalytic performances by mussel chemistry. Polydopamine (PDA) serves as the biomimetic adhesive layer and then connects MoS2 nanoparticles with g-C3N4 nanotubes (CNNTs). The obtained nanocomposites were characterized by FT-IR spectra, XRD, SEM, TEM, XPS, U

Abstract:

Our approach to the design of biological material scaffolds for bone regeneration is the creation of cell environments that mimic natural tissues. Recently, we confirmed hitologically that the material surfaces of conventional, nonabsorbable ceramics shed body fluid. For bone engineering, it is known that ideal scaffolds should be bioabsorbable, mimetic, and hydrophilic materials that allow for the permeation of liquid components, such as blood and/or extracellular fluid. In our previous study showed functionally graded hydroxyapatite (fg-HAp) absorbed body fluid including albumin. In this stu

Abstract:

Anterior cruciate ligament (ACL) injuries pose significant challenges, driving the need for innovative repair strategies. Tissue engineering (TE) has emerged as a promising field for ACL injuries. Wet spinning is a filament production technique that enables precise control over filament alignment, diameter, and porosity, making it suitable for developing new scaffolds for ACL injuries. This study develops fibrous scaffolds using wet spinning of polycaprolactone (PCL) reinforced with cellulose nanocrystals (CNC) to enhance mechanical properties. Wet spinning was employed to fabricate fibrous sc

Abstract:

The association between physical activity in achieving mental health benefits and subjective well-being is consistently identified by empirical research. The causation of a positive self-concept created by physical exercise is empirically supported by Sonstroem and Morgan’s (1988) exercise and self-esteem model (EXSEM). However, various drawbacks of maintaining high self-esteem have been identified; thus, the concept of self-compassion was conjectured to be a form of “true self-esteem.” Hence, the current study aimed to investigate the relationship between physical activity and self-compassion

Abstract:

Cutaneous candidiasis is an opportunistic infection that arises, in most cases, from endogenous, saprophytic candidal blastospores that selectively colonize oral, gastrointestinal, vaginal, and cutaneous epithelium. Candida albicans has been regarded as the most common causative agent in human fungal infections. However, other Candida species have become a significant cause of infection. Scanning electron microscope (SEM) observations were used to analyze the capability of C. albicans, C. tropicalis, and C. parapsilosis to adhere to human skin model, used in this study, which was found to mimi

Abstract:

Amazonian Dark Earths (Terra Preta) are anthropogenic soils with high organic carbon content and the ability to sustain higher fertility than adjacent, intensely weathered, acidic soils. Consequently, the microstructural development of biochar–mineral complexes, termed synthetic Terra Preta (STP), has been investigated. Here, biochar–mineral complexes are produced at elevated temperatures to mimic the structure of Terra Preta. These materials, if added to soils, may then also improve fertility. The raw materials used in STP were organic biowaste, such as sawdust, chicken manure, and blood and

Abstract Pores have been the main focus of quality assurance in castings. Latest research has shown that in aluminium castings pores can form only if there is existing entrainment damage, i.e., pores are merely the visible parts of the entrainment damage, and usually invisible damage is much more extensive. However, its effect on deformation behaviour has not been previously established or observed in-situ.

The texture profile analysis (TPA) results indicated that the hardness, cohesiveness, and chewiness of the samples improved significantly after appropriate SPS and KGM addition.
