- Irreversible crystal-to-crystal transformations of 3D lead(II) coordination polymers with the ligand 1H-1,2,4-
triazole-3-carboxylic acid (HL), from [Pb(L)(µ2-Cl)(H2O)]n (1) to [Pb(L)(µ2-Br)(H2O)]n (2) and [Pb(L)(µ1,1-NCS)(H2O)]n (3)
by solid-state anion-replacement processes under mechanochemical reactions, have been studied.

The Low-Pressure Acetylene Generators used calcium carbide to generate
Acetylene gas. The generated low-pressure Acetylene is used with an oxygen
cylinder extensively by Gas welders in Chhattisgarh state for oxy acetylene
welding. This low-pressure oxy acetylene welding is used mostly in
automobile body repairing work. In this research paper mainly four types of
popular generators are used to study for producing low-pressure Acetylene.
The design construction and working of these lookalike generators are
similar but their capacities and safety to hold the Acetylene gas are different.
These generators are selected by the gas welders as per the experience and
skill developed by them.

Nowadays, the drastic participation of the nanosized materials in technology have been implicated with various applications which mainly aims the performance optimization, dimensional downscaling, ultra-low power consumption etc. to overcome the fundamental limits of the microscale devices.
