New Zealand: Indian-origin man fights robbers

Wellington: An Indian-origin man fought with two robbers who stole his cash register in Christchurch, the largest city in the South Island of New Zealand.

Kamlesh Patel, a dairy owner, said two men entered his Opawa Universal Dairy and tried to flee with the cash register at about 7.40 PM.

He chased down the men and caught one and held him captive until the police arrived.

The second man involved in the attempted robbery managed to escape after his partner was caught.

“They ran away with the cash register. I started chasing him. He dropped the cash register and I caught him,” Patel was quoted as saying.

“[The cash register] was too heavy for them. It’s too heavy for me,” he added.

Patel was at the dairy with several friends and family members. The group held on to the offender until the police arrived a short time later.

Five years ago, a man demanding cash and tobacco robbed Patel at gunpoint. Patel tried and stopped the offender that time too, and received minor head injuries as he tried to wrestle the rifle from the offender.

Patel said he did not believe the men involved in the attempted robbery were armed.

Patel said that no one was hurt during the incident.

“Shoplifters keep coming, but this is different,” he was quoted as saying.(IANS)

Scientists Produce Complex Glass From 3D Printing

The researchers can change various parameters in each layer, including pore size.

Creating glass objects using 3D printing is not easy but a groups of researchers including one of Indian-origin has now used a better technique to produce complex glass objects with addictive manufacturing.

Researchers from ETH Zurich (Swiss Federal Institute of Technology in Zurich) used the method based on stereolithography, one of the first 3D printing techniques developed during the 1980s.

David Moore, Lorenzo Barbera and Kunal Masania in the Complex Materials group led by ETH processor Andre Studart developed a special resin that contains a plastic and organic molecules to which glass precursors are bonded.

The resin can be processed using commercially available ‘Digital Light Processing’ technology.

This involves irradiating the resin with UV light patterns. Wherever the light strikes the resin, it hardens because the light sensitive components of the polymer resin cross link at the exposed points.

The plastic monomers combine to form a labyrinth like structure, creating the polymer. The ceramic-bearing molecules fill the interstices of this labyrinth, said the team in a paper published in the journal Natural Materials.

An object can thus be built up layer by layer. The researchers can change various parameters in each layer, including pore size.

“We discovered that by accident, but we can use this to directly influence the pore size of the printed object,” said Masania.

These 3D-printed glass objects are still no bigger than a die. Large glass objects, such as bottles, drinking glasses or window panes, cannot be produced in this way “which was not actually the goal of the project,” emphasised Masania.

The aim was rather to prove the feasibility of producing glass objects of complex geometry using a 3D printing process. However, the new technology is not just a gimmick.

The researchers applied for a patent and are currently negotiating with a major Swiss glassware dealer who wants to use the technology in his company. (IANS)
