The US President recently said the conflict between Russia and Ukraine had driven up the prices of all the world's major food staples, including wheat, corn, barley, oilseeds and edible oils, and that Russia and Ukraine together supplied more than 25% of the world's wheat exports and about 20% of its barley exports.
To address the food shortage, the Biden administration says it plans to increase the number of counties eligible for insurance for double cropping. Double cropping is when farmers grow two different crops a year on the same field.
Under Biden's plan, the number of counties eligible for two-season crop insurance would increase by 681, for a total of 1,935.
The UN has warned that up to 1.7bn people are "highly exposed" to the domino effect of the conflict between Russia and Ukraine on the global food, energy, and financial systems. The agency says conflict could increase hunger in countries where people are already suffering from malnutrition.
Even countries where food is less scarce are being hit by rising prices. U.S. grocery prices rose 1% in April, compared with a 10.8% increase over the past 12 months, the Labor Department said recently.
According to the White House, global food prices have risen nearly 13 percent since the outbreak of the Russia-Ukraine conflict.

Overview of titanium sulfide TiS2 powder
Titanium disulfide is an inorganic compound with the molecular formula TiS2. Brass scaly crystals with metallic luster. The density is 3.22 g/mL. Stable at room temperature, stable to water, dilute sulfuric acid and hydrochloric acid, but nitric acid and concentrated sulfuric acid will decompose into sulfur. Lithium can be inserted between the titanium disulfide layers, and the composition of the inner layer-forming compound LiTiS2 varies continuously between x=0 and 1, which is an ideal non-stoichiometric compound. Titanium disulfide is a yellow or gray powder with an unpleasant odor and is used as a solid lubricant. Contact with this substance may cause burns to skin, eyes and mucous membranes. May be toxic if swallowed, inhaled or absorbed through skin.
Titanium disulfide is prepared by reacting the elements at around 500 °C.
Ti + 2 S → TiS2
It can be synthesized more easily from titanium tetrachloride, but the purity of this product is usually lower than that obtained from the element.
TiCl4 + 2 H2S → TiS2 + 4 HCl
This route has been applied to the formation of TiS2 thin films by chemical vapor deposition. Instead of hydrogen sulfide, mercaptans and organic disulfides can be used.
Various other titanium sulfides are known.
Titanium sulfide TiS2 powder application
Titanium sulfide TiS2 powder is mainly used for lithium batteries, targets, scientific research, etc.
In 1973, the prospect of using titanium disulfide as a cathode material for rechargeable batteries was proposed. Group IV and Group V halogen compounds have attracted attention due to their high electrical conductivity. The battery originally described used a lithium anode and a titanium disulfide cathode. The battery has high energy density, and the diffusion process of lithium ions to the titanium disulfide positive electrode is reversible and rechargeable.
Titanium disulfide TiS2 powder was chosen because it is the lightest and cheapest chalcogenide.
Lithium ions diffuse the fastest in titanium disulfide.
The main problem is the degradation of the cathode after repeated use. This reversible insertion process allows the battery to recharge. Furthermore, among all the layered dihalides IV and V, titanium disulfide is the lightest and cheapest.
In the 1990s, titanium disulfide was replaced by other cathode materials (manganese oxide and cobalt oxide) in most rechargeable batteries.
Use of TiS2 Cathode in Solid-State Lithium Batteries Most Li-ion batteries use liquid electrolytes, which may pose safety hazards due to their flammability. Many different solid electrolytes have been proposed to replace these detrimental liquid electrolytes.
For most solid-state batteries, higher interfacial resistance reduces the reversibility of the insertion process and shortens the lifetime. For TIS2, these poor interface effects are no longer a problem. The power density of the all-solid-state lithium battery is 1000 W/kg, and the maximum power density for 50 cycles is 1500 W/kg. In addition, the average capacity of the battery dropped by less than 10% in 50 cycles. Although titanium disulfide has high electrical conductivity, high energy density, and high power, its discharge voltage is relatively low compared to other lithium batteries with high reduction potential cathodes.

The EU’s draft REPowerEU plan calls for an increase of 15TWh of rooftop PV capacity by 2022. The draft also calls for EU and national governments to take action this year to reduce the time required to obtain permits for rooftop PV installations to three months, and proposes that "all new buildings and existing buildings with an energy grade OF D or above should have rooftop PV installations by 2025".
In addition, the European Commission is likely to set a target for installed PV capacity of 300GW by 2025 and 500GW by 2030. Some members are more aggressive, with Austria, Belgium, Lithuania, Luxembourg, and Spain demanding a 1TW target for 2030.
The REPowerEU initiative, worth 195 billion euros, was proposed by the EU on March 8 to phase out member states' dependence on Russian fossil fuels by 2030. In a few days, the European Commission will present a package to implement the RePowerEU strategy.
As an important application scenario of distributed PV, rooftop PV is not limited to land, and the development conditions are relatively convenient.
Since the end of 2021, Spain, France, the Netherlands, and other countries have introduced policies and measures such as government subsidies, tax cuts, fee reductions, and accelerated grid-connection approval to encourage the development of distributed PV. Europe's potential for rooftop PV is huge and will continue to be an important growth pole for the industry, according to Wood Mackenzie.
