Objectives: To identify the effects of indium on lung and to assess exposure-effect exposure-response relations between exposure lungs. Methods: Ninety three male exposed 93 non-exposed workers from four ITO manufacturing or recycling plants were analysed in a cross-sectional study. Indium serum (In-S) was determined as biological index. Geometric means (GSD) In-S 8.25 ng/ml (4.55) 0.25 (2.64) workers. The maximum concentration 116.9 ng/ml. A questionnaire for respiratory symptoms job...

Molecular imprinting technology is becoming a versatile tool for the preparation of tailor-made molecular recognition elements. This work investigates performance hemin-modified molecularly imprinted polymer (MIP) used as an amperometric sensor detection 4-aminophenol (4-APh). MIP particles were prepared by precipitation polymerization method with hemin introduced catalytic center to mimic active site peroxidase. 4-APh was template molecule, methacrylic acid (MAA) functional monomer,...
The design and development of efficient electrocatalytic sensitive nickel oxide nanomaterials have attracted attention as they are considered cost-effective, stable, abundant sensors. However, although innumerable electrocatalysts been reported, their large-scale production with the same activity sensitivity remains challenging. In this study, we report a simple protocol for gram-scale synthesis uniform NiO nanoflowers (approximately 1.75 g) via hydrothermal method highly selective detection...
Hydrogen (H2) has emerged as a sustainable energy carrier capable of replacing/complementing the global carbon-based matrix. Although studies in this area have often focused on fundamental understanding catalytic processes and demonstration their activities towards different strategies, much effort is still needed to develop high-performance technologies advanced materials accomplish widespread utilization. The main goal review discuss recent contributions H2 production field by employing...
Infectious and Parasitic Diseases (IPD) remain a challenge for medicine due to several interconnected reasons, such as antimicrobial resistance (AMR). American tegumentary leishmaniasis (ATL) is an overlooked IPD causing persistent skin ulcers that are challenging heal, resulting in disfiguring scars. Moreover, it has the potential extend from mucous membranes of nose, mouth, throat both humans various animals. Given limited effectiveness AMR current drugs, exploration new substances emerged...
Experiments aiming at 'day long operation high performance' have been carried out in TRIAM-1M. The record value of the discharge duration was updated to 5 h and 16 min. Steady-state tokamak is studied under localized plasma wall interaction conditions. distributions heat load, particle recycling flux impurity source are investigated understand co-deposition pumping. formation sustainment an internal transport barrier (ITB) enhanced current drive mode has by controlling lower hybrid driven...
This work investigates the mechanisms by which Sn and Ru can improve or inhibit site-specific catalytic activity of Pt (neighboring distant from foreign atoms) at bimetallic surfaces. For this purpose, we decorated stepped surfaces (nonequivalent sites) site-selective electrodeposition different coverages either on (110) steps, forming Snsteps/Pt(hkl) Rusteps/Pt(hkl) surfaces, used CO adlayer electro-oxidation as a surface probe reaction, monitored in situ FTIR cyclic voltammetry techniques....
MnOx-based nanomaterials are promising large-scale electrochemical energy storage devices due to their high specific capacity, low toxicity, and cost. However, slow diffusion kinetics is still challenging, restricting practical applications. Here, a one-pot straightforward method was reported produce Zn-doped MnOx nanowires with abundant defects tunable small cross-sections, exhibiting an outstanding capacitance. More specifically, based on facile hydrothermal strategy, zinc sites could be...
