How does sun exposure affect the chemical properties of colloidal silver?4 answersExposure to sunlight can have various effects on the chemical properties of colloidal silver. Sunlight irradiation can lead to the reduction of silver sulfide (Ag2S) nanoparticles to metallic silver (Ag) and/or the formation of Ag2S/Ag hybrid nanoparticles. The size of the primary particles of silver nanosuspensions is a major factor determining their evolution under sunlight irradiation, with smaller particles undergoing dissolution and the formation of nanoseeds and nanoprisms, while larger particles undergo shape modifications and aggregation. The electrostatic-stabilizing citrate in silver nanoparticle suspensions promotes particle morphology changes, while the steric-stabilizing PEG is reduced by sunlight irradiation, leading to aggregation and sedimentation. Sunlight exposure can also cause changes in the surface state and size of silver colloids, as observed through cyclic voltammetry and absorption spectroscopy. The role of UV and short-wavelength electromagnetic radiation in the formation of colloidal silver has also been recognized, with UV exposure playing a crucial role in the production of colloidal silver.
What are the effects of gamma radiation on Borago officinalis?5 answersGamma radiation has various effects on Borago officinalis. The use of gamma irradiation doses ranging from 2 to 10 kilo rad (kr) resulted in increased plant height, dry weight of herb per plant, number of inflorescences per plant, seed yield per plant and per faddan, fixed oil percentage, and leaf green color degree. Gamma irradiation at doses of 1 and 10 kGy did not significantly affect the nutritional value of borututu, but the sample irradiated at 10 kGy had the highest energetic contribution, total sugars, organic acids, total tocopherols, and PUFA contents. It also exhibited the highest levels of total phenolics and flavonoids, as well as the highest antioxidant activity. Borage seeds oil showed a protective effect against gamma radiation-induced oxidative stress in male rats, improving the natural antioxidant mechanism and reducing hepatotoxicity. Gamma irradiation at a dose of 25 Gy was found to be beneficial for growth and flowering characteristics in African marigold cv. Pusa Narangi Gainda.

Does gamma ray exposure affect on net photosynthesis?5 answersGamma ray exposure has been found to have an impact on net photosynthesis. Lower doses of gamma irradiation (100Gy and 200Gy) have been shown to stimulate the net photosynthetic assimilation rate in plants such as T. arjuna. Similarly, in Centella asiatica, a CO2-enriched atmosphere combined with gamma irradiation resulted in an increase in the maximum net photosynthesis rate and the efficiency of photosystem II. However, higher doses of gamma irradiation (above 200Gy) have been found to decrease net photosynthesis in T. arjunaand inhibit photosynthesis, carbon assimilation efficiency, and nitrogen assimilation efficiency in wheat. Overall, the effect of gamma ray exposure on net photosynthesis appears to be dose-dependent, with lower doses potentially stimulating photosynthesis and higher doses inhibiting it.
What are the effects of gamma rays on photoelectric cells?5 answersGamma rays have various effects on photoelectric cells. When exposed to gamma radiation, the performance of solar cells, such as open circuit voltage (Voc), short circuit current (Isc), and efficiency (η), decreases. This decrease in performance is observed in both mono-crystalline and polycrystalline solar cells. Additionally, the current-voltage characteristics of optoelectronic devices, including PIN photodiodes, phototransistors, and solar panels, are affected by gamma irradiation. However, it is possible to enhance the efficiency and operational life of photovoltaic cells by incorporating a scintillator between the high-energy nuclear isomer and the semiconductor materials of the cell. Furthermore, the performance of aged silicon solar cells degraded by gamma radiation can be significantly recovered through MHz-frequency ultrasonic treatment (UST).
What is the effect of electron beam on the material?5 answersElectron beam irradiation of materials in electron microscopy can lead to damage and visible changes in structure or chemistry. However, under certain conditions, electron irradiation can trigger controlled structural evolution or chemical reactivity, allowing real-time monitoring with atomic resolution. The effects of electron beam on materials include knock-on damage, radiolytic processes, and damage by induced electric field (DIEM). DIEM mechanism dominates in insulating materials that conduct electricity to ions but not to electrons. The strength of the induced electric field depends on the dielectric properties of the material and the beam current density. Computational studies have shown that fast electron energy loss due to stopping is similar in Al, Cu, and Ag, but much higher in Au. Ohmic stopping dominates over collisional stopping in most materials. In situ TEM characterization has revealed that electron beam irradiation can significantly affect the type of defects formed and the final defect microstructure in materials under self-ion irradiation and annealing. The large doses delivered during high-resolution TEM work can cause damage to radiation-sensitive materials, and efforts are being made to mitigate this damage by building up signal from a large number of independent acquisitions with a low signal-to-noise ratio.

Regarding ABTS, what is the implication of an absorbance decrease but an increase in decolorization (%)?
5 answers
The implication of an absorbance decrease but an increase in decolorization (%) when using ABTS is indicative of efficient antioxidant activity. This phenomenon suggests that the antioxidant is effectively reducing the ABTS radical cation, leading to a decrease in absorbance due to the antioxidant's ability to neutralize the radical species. The increase in decolorization (%) signifies the antioxidant's capacity to facilitate the breakdown of chromophoric groups, resulting in the removal of color from the system. This efficient decolorization process is crucial for assessing the antioxidant potential of compounds and complex mixtures. The combination of absorbance decrease and increased decolorization (%) highlights the antioxidant's ability to scavenge free radicals effectively and underscores its potential application in various biotechnological and environmental processes.

How does the addition of DEHP affect the tensile strength of PVC?
5 answers
The addition of Di-2-ethylhexyl phthalate (DEHP) as a plasticizer to PVC has varying effects on the tensile strength of the material. Research indicates that the presence of DEHP can lead to a decrease in tensile strength and Young's modulus of PVC blends, as observed in studies on PVC/PMMA blends.
