Explain: Future of Rare Earth Metals

Due to growing environmental concerns and rising per capita spending, hybrid and electronic vehicles are becoming increasingly popular throughout industrialized nations. The use of rare earth metals in the manufacture of vehicles will continue to drive the demand for these materials.

Dysprosium and neodymium are two rare earth metals utilized in rare earth magnets. Both traditional and hybrid car batteries use these magnets extensively. These materials in electronics and wind turbines will continue to expand due to their outstanding performance and excellent magnetic strength. The sale of rare earth metals is expected to produce $15,473.0 million by 2030.

What Are the Applications of Rare Earth Metals?

Many industries use rare earth metals, including automotive, electronic, and renewable energy. Wind turbines in the renewable energy sector use rare-earth magnets. Dysprosium and neodymium, two rare earth metals, are used to make permanent magnets.

The wind turbine gears are divided using magnets, which minimizes weight and removes maintenance concerns. Lanthanum and cerium are the most favored rare earth metals for use in catalyst systems. The oil and gas industry primarily uses these metals in vehicle catalytic converters and liquid cracking catalysts.

Implementing strict laws meant to reduce emissions from machinery and vehicles across the globe is driving up demand for auto-catalysts and driving the sales of rare earth metals. Due to their great magnetic strength and efficiency, rare-earth magnets are also utilized in consumer goods like hard drives, cellphones, and other electronic components.

Types of Rare Earth Metals

• Cerium

Among the rare-earth elements, cerium is among the most prevalent. Monazite, allanite or orthrite, cerite, bastnasite, and samarskite are a few minerals. Cerium has been discovered in significant quantities in India, Brazil, and Southern California.

Cerium oxide is used in glass polishing compounds, self-cleaning ovens, and incandescent gas mantles. Cerium is also widely used in carbon arc lights for projector and studio lighting in the television and film industries.

• Neodymium

The chemical element neodymium has the atomic number 60 and the letter Nd assigned to it. Moreover, it is regarded as one of the rare-earth metals and is the fourth compound in the lanthanide series.

It is a silvery, hard, somewhat malleable metal that tarnishes easily when exposed to air and moisture. Additionally, the high strength of neodymium aids in the reduction of the size of the electric motors used in EVs. Neodymium is commonly used in an alloy with boron and iron to create mighty permanent magnets. 

• Lanthanum

Because it enhances the glass' optical qualities and alkali resistance, lanthanum oxide is utilized to create specialized optical glasses. Salts of lanthanum are employed as catalysts in the refinement of petroleum. It is used in various electronics, including energy-efficient lighting, TVs, and fluorescent tubes.

Additionally, it serves as a cleaning agent in various consumer goods and is utilized in manufacturing catalysts. Thus, as people's lifestyles worldwide improve, so does the need for metal. There are several further varieties of rare earth metals, including dysprosium, terbium, yttrium and scandium.

Everything You Need to Know About PEG Family

What are PEGs?

You have perhaps noticed that many cosmetics you use have different types of PEGs among ingredients. Polyethylene glycol, is not a conclusive chemical entity in itself, but a mixt of compounds, polymers having been bonded together. Polyethylene is the utmost common form of plastic, and when combined with glycol, becomes a thick and tacky liquid.

PEGs are virtually frequently followed by a number, for instance PEG-8, PEG-6, PEG-100 etc. This number signifies the estimated molecular mass of that compound. Characteristically, cosmetics make use of PEGs with smaller molecular mass. The lesser the molecular weight, the easier it is for the composite to enter the skin. Frequently, PEGs are associated to additional molecule. You may see, for instance, PEG 100 as an element. This means that the PEG polymer with an estimated molecular weight of hundred is attached chemically to stearic acid.

In make-ups, PEGs function in 3 ways: as emollients, as emulsifiers, and as automobiles helping deliver other constituents deeper in the skin.

What effect do PEGs have on your skin?

PEG compounds have not attained a lot of attention from customer groups but they ought. The most significant thing to recognize about PEGs is that they have a penetration improving effect, the scale of which is reliant on upon a variability of variables. These comprise of: both the construction and molecular weight of the Polyethylene glycol, other chemical ingredients in the formulation, and, most prominently, the overall skin health.

PEGs of all dimensions may enter through incapacitated skin with compromised barrier function. So, it is very significant to evade products with PEGs if the skin is not in finest condition. Skin infiltration enhancing effects are there with PEG-2 and PEG-9 stearate.

This effect is significant for three reasons: 

1) If your cosmetic product comprises a bunch of additional undesirable elements, PEGs will make it easy for them to get deep into the skin.

2) By changing the skin’s surface tension, PEGs might upset the usual moisture balance. 

3) PEGs are not at all times pure, but contaminated with toxic impurities.

When there is PEGs in Cosmetics…

• Although you may find conflicting info online regarding Polyethylene Glycol, you have to be attentive when choosing cosmetic products.

• For a sensitive or damaged skin, it is a good idea avoiding products comprising PEGs.

• Natural glycols are a decent substitute to PEGs, for instance vegetable glycerin can be used as moisturiser and emulsifier. 

• Now, there is not enough info on product tags to enabling you to regulate whether PEG compounds are polluted. But if you buy a product comprising PEGs ensure that PEGs are from a respected brand.

There is no doubt that there is mixed info available about polyethylene glycol, but it is not stopping the demand for the same to rise all over the world. The total demand of the chemical will reach to a value of around $6,910 million by 2030, and that too at a rate of around 5%.

How Do Lithium-Ion Batteries Contribute to Reducing GHG Emissions?

In 2021, the Li-ion battery industry generates $46,142.1 million revenue, and it is projected to contribute $165,847.8 million in 2030, advancing at a rate of 15.3%. It is led by the rising demand for renewable energy and increasing lithium-ion batteries adoption in consumer electronics. 

The worldwide increasing focus on sustainable energy is led by the rising concerns on environmental consequences such as rising GHG emissions caused by the burning of fossil fuels and increasing consumption of electricity.

Moreover, the transportation systems cause 25% of the global greenhouse gas emissions to the environment, according to the United Nations (UN). Thus, governments are encouraging the adoption of electric vehicles to achieve sustainable and eco-friendly living. 

In 2021, the automotive captures an extensive share of the industry, accounting for 31.1% and it is predicted to rise at a rate of 15.7% by 2030. It is led by the rising adoption of EVs in both developing and developed countries to significantly reduce carbon emissions, and shift from conventional vehicles to EVs. 

APAC captures a significant share of the industry, amounting to $24,586.2 million revenue, accounting for 53.3% share. The consumer electronics demand is massively rising, which, in turn, fuels the industry's growth. The rapid technical breakthroughs and massive demand for smart devices boost the adoption of such batteries.

Therefore, the growing adoption of EVs led by rising environmental concerns boosts the consumption of lithium-ion batteries.
