Abstract.
In pressure die casting, spraying the surface of the casting die with detaching material is a really important technological step, and spraying time - as a part of cycle time influencing productivity - is a very significant parameter.

Things were handled prior to operational needs to bring the relevant materials, go to the relevant windows Missionary Board handled a problem if the material also need multi-entry.
Now things just need to log into the site's collaborative district government office system, a one-time fill in all the materials needed.
If the material problems of staff and clerical staff can communicate through the system until the material is correct, then the acting person can submit material to the window to collect the results.
Able to save more, save manpower and material resources, the government expenditure greatly improve the government informationization construction efficiency.

Introduction
Low plasticity at room temperature and under plastic working conditions as well as susceptibility to brittle cracking significantly limit the use of two-phase TiAl intermetallic alloys as construction materials [1÷8].
Materials and research methodology A two-phase Ti–48Al–2Cr–2Nb (at.%) alloy with chemical composition as specified in table 1 was used like the most representative one in the group of two-phase TiAl intermetallic alloys.

Abstract.
Bi-2223 superconductor was considered to be among the most valuable superconducting materials for a variety of reasons, including their relatively high critical temperature (Tc) and high critical current density (Jc), which are very useful in the production of large magnetic fields, such as in particle accelerators and the medical field, where magnetic resonance imaging (MRI) is used, as well as in many electrical power appliances where energy losses can be reduced with the help of these materials [1,2].
The influence of doping materials like Ce [5], Sm [6], Ni [7], Dy [8] and GO [9] on the Bi-based superconductors has been reported by various authors.
Materials and Method The preparations of high and low density Bi1.6Pb0.4Sr2(Ca2-xEux)Cu3Oy where x = 0.00, 0.0025, 0.02, 0.05 and 0.07 was carried out by solid state reaction method using Bismuth (III) oxide, Bi2O3 (99.99%), Lead (II) oxide, PbO (99.90%), Strontium carbonate, SrCO3 (99.99%), Calcium carbonate, CaCO3 (99.00%), Copper (II) oxide, CuO (99.00%), Europium (III) oxide nanopowders, Eu2O3 (99.50%) and Sucrose Crystalline, C12H22O11.

Osinowo et al. [14] took a different approach by developing a low-cost pyrometer using locally sourced materials.
The design employed a simple resistor-potentiometer network for current regulation and analog-to-digital conversion, confirming that a cost-effective and accurate sensor could be produced with locally sourced materials and basic electronics, offering a reliable alternative to more expensive commercial sensors.
The total project cost, encompassing one-time materials and a multimeter for accurate measurement, amounted to approximately $123.84.
