“…These are electro-depositions, Spray pyrolysis, and Photo accelerated biochemical depositions 17 , void evaporations solid–gas depositions 18 . Generally, the provision of thin films had been applied through several procedures such as D-C magnetrons spluttering 19 , pulses electro-deposition techniques 20 , thermal vaporization technique 21 rf magnetrons sputtering 22 , Sprays Pyrolysis technique 23 as well as CBD (chemical bath deposition) techniques 24 . When a chemical bath is equated with the above approaches, it is comparatively simpler, more quick and cheap.…”

The translucent and nano-crystalline PbS films were equipped with the CBD techniques on metal substrates by the temperature of 90 °C through aqueous solutions of Lead Nitrate and Thiourea. The XRD phases verify the crystalline property of synthesized thin films that the shape falls in the cubic structures with favourite orientations. It revealed that the prepared material is cubic crystal oriented as (111), (110), (100) and (101) crystal planes. The crystalline size varied between 0.4 and 0.7 nm. The band gap was assessed using UV–vis captivation spectra and Tau relations. The average energy band gap was found to be 2.43 eV which is greater than bulk materials of PbS; because of quantum confinements of Lead Sulfide Nano Crystalline thin films, and PL also confirms this result. The variation in band gap with Leaf extracts and particle sizes displayed blue shifts characteristic of electrons quantum confinements. SEM micrograph shows extremely uniform and adherent PbS films are found at higher PH values. It was evidently observed that the viscosity of the synthesized thin films reduced from 563 to 111 nm with a rise in pH value. The sample prepared at pH 4 shows good performance, and thin films deposited from Avocado (Glycosmis cochinchinensis) leaf extracts are a promising method to empower pollution remediation and future energy.

“…The majority of the highest PL hardness is because of self-trapped exciton recombination, which is produced from particle size and is referred to as defect centres. For all elevated temperatures, the PL intensity drops instantaneously as a function of the aging time [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. In comparison, the photoluminescence intensity for wavelengths of higher wavelength for 60 min and 50 min is smaller than 40 min for wavelength intensity for higher aging time.…”

“…In addition, we discuss some of the risks and challenges associated with the development of cost-effective and environmentally acceptable functional nanomaterials for water purification. Since the last few years, desalination technology has been used progressively all over the world to yield pure drinking water from briny groundwater and seawater, to recover the feature of prevailing provisions of freshwater for consumption and engineering dedications, agricultural needs and luxury manufacturing [9][10][11][12]. TiO 2 nanosheets were prepared by using CBD.…”

Nanotechnology from titanium dioxide has been deposited, and its application in desalination and water treatment has been investigated by using sol-gel methods. Homogeneously dispersed sphere shapes of titanium dioxide nanoparticles were observed from scanning electron microscope micrographs and decrease in size as aging time increases from 40 min to 60 min. SEM micrographs of highly transparent nanopowders show that they are detected in the visible region from UV/visible and that their red shift around maximum wavelength increases with increasing aging time due to an increase in water quality. The energy band gap of the generated nanosheet has narrowed as the aging time has increased, which is related to the red shift of the absorption spectrum edge in the sheet. The structural behaviors of deposited nanoparticles have also been investigated, which confirms the existence of anatase as well as rutile levels in the liquid phase. The findings of the PL allowed us to determine the total strength of the intensity. This shows that applying photodegradation by a solar absorber could play a vital role in desalination and water treatment.

“…The influence of gender and lead exposure on reaction time in our study should be cautiously interpreted because of the cross-sectional design and confounding by co-exposures of tobacco smoking and other neurotoxic metals contained in batik dye, especially copper and cadmium [ 67 , 68 , 69 , 70 ]. Longitudinal studies on newly lead-exposed non-smoker workers are needed to establish the causal relationship between chronic lead exposure and reaction time.…”

(1) Background: Neglected occupational health and safety aspects in batik industries cause their workers to have an increased risk of lead exposure. The effect of occupational lead exposure on neurocognitive performance is inconclusive. Therefore, we conducted an observational study to examine the difference in simple reaction time between lead-exposed batik workers and non-exposed referents. (2) Methods: This cross-sectional study was conducted in seven batik enterprises in Lendah District, Indonesia, excluding workers with medical conditions impairing reaction time. Simple reaction time tests were conducted using an online tool. Two-way model ANCOVAs examined interactions between gender and job types on the mean differences in reaction time. (3) Results: After controlling for age and body mass index, we observed longer reaction times among lead-exposed batik workers than non-exposed referents with an adjusted mean difference of 0.19 (95% CI: 0.016–0.368) seconds. A more prominent detrimental effect of lead exposure on reaction time among female workers than among male workers was observed. (4) Conclusions: Our results suggest that occupational lead exposure could contribute to longer reaction time, notably among female workers. Thus, occupational health and safety precautions are vital to protect batik workers and preserve their important contributions to cultural heritage.
