 Fourth, since the sulfate required for the production of the present invention is provided by the acid leaching slag itself, the mass fraction of the SO/- contained in the acid leaching slag is 15% or more, and the nanometer is prepared by using the acid leaching residue as the zinc and sulfate raw material of the lithopone. Lide powder products not only realize the resource utilization of acid leaching slag, but also turn waste into treasure, and treat and improve the acidic soil of acid leaching residue to purify the environment. Low production costs and simple operation. The metathesis reaction is carried out in a low-density ammonia system (the metathesis reactant is dissolved in recovered ammonia water), and the crystal nucleus formed is smaller. It is non-toxic and safe. The ammonia solution after synthesis and separation is returned to the leaching. There is no waste water in the whole production process. The produced waste residue meets the national solid waste discharge standard for efflux, conforms to the national industrial policy, and is an environmentally friendly “green” type process.

This article discusses the discovery of phosphorescent lithopone on watercolor drawings by American artist John La Farge dated between 1890 and 1905 and the history of lithopone in the pigment industry in the late 19th and early 20th centuries. Despite having many desirable qualities for use in white watercolor or oil paints, the development of lithopone as an artists’ pigment was hampered by its tendency to darken in sunlight. Its availability to, and adoption by, artists remain unclear, as colormen's trade catalogs were generally not explicit in describing white pigments as containing lithopone. Further, lithopone may be mistaken for lead white during visual examination and its short-lived phosphorescence can be easily missed by the uninformed observer. Phosphorescent lithopone has been documented on only one other work-to-date: a watercolor by Van Gogh. In addition to the history of lithopone's manufacture, the article details the mechanism for its phosphorescence and its identification aided by Raman spectroscopy and spectrofluorimetry.

Lithopone’s historical significance is further accentuated by the advancements and modifications that followed its inception. The 1874 patent by J.B. Orr, for instance, ushered in a new white pigment—Orr’s Zinc White. This innovation was attained by co-precipitating zinc sulfate and barium sulfide, followed by a calcination process. Further refinements marked the subsequent decades, the most notable being the enhancement of lightfastness achieved in the 1920s by introducing small amounts of cobalt salts before calcination.

  • In conclusion, off-grid solar power systems present a compelling solution for individuals and communities seeking energy independence, environmental sustainability, and resilience against grid failures. They harness the abundant energy of the sun, significantly reduce carbon emissions, and offer financial savings over time. While challenges such as energy storage and system planning exist, advancements in technology and growing awareness of renewable energy make off-grid solar more accessible and practical than ever. As we move towards a cleaner, more sustainable future, off-grid solar systems are likely to play an increasingly important role in our energy landscape.


  • While the initial investment in an off-grid solar system may be substantial, many users find that the long-term savings on energy bills can outweigh these costs. Once the system is paid off, the ongoing energy expense decreases dramatically, particularly in areas with high electricity prices. Additionally, off-grid systems can increase property value and provide resilience against power outages and rising utility rates.


  • While the initial cost of solar panels may seem high, potential buyers should consider governmental incentives that can significantly reduce the upfront investment. In many countries, tax credits, rebates, and grants are available for solar energy installations. For instance, in the United States, the federal solar tax credit (Investment Tax Credit) allows homeowners to deduct a significant portion of the installation costs from their taxes.


  • Solar security lighting

  • Did you know that solar panels work just as well in the UK as they do anywhere else in the world, regardless of the weather? You don't need to live in a place that's sunny all year round to generate solar energy. Even on cloudy days, solar panels can still generate energy. However, it's worth noting that the more sunshine you get, the more energy you'll produce.

  • The price per watt of monocrystalline solar panels is a critical consideration for anyone looking to invest in solar energy. While upfront costs can be substantial, the benefits—including efficiency, longevity, and potential savings—make them a worthwhile investment. As technology continues to advance and prices fluctuate, consumers are encouraged to conduct thorough research, compare options, and consider local incentives to make informed decisions. Embracing solar energy not only supports personal financial goals but also contributes positively to environmental sustainability.
