US President Donald Trump has said that India
and China are no longer developing nations and both are taking advantage of
developing nations tag from the World Trade Organization.
Addressing a gathering at Pennsylvania, Trump said
India and China, the two economic giants from Asia, are no longer developing
nations and they cannot take benefits from WTO. However, they are taking the
advantage of a developing nation tag from the WTO, putting the US to
Trump, championing his America First policy, has
been a vocal critic of India for levying allegedly high duties on US products.
The US and China are currently engaged in a bruising trade war after Trump
imposed punitive tariffs on Chinese goods. Beijing retaliated in the same manner
by imposing tariffs on the American goods.
Earlier in July, Trump asked WTO to define how it
designates developing country status, a move apparently aimed at singling out
countries like China, Turkey and India which are getting lenient treatment under
the global trade rules.
Researchers from the Indian Institute of
Technology-Hyderabad (IIT-H) and Dr. B.R. Ambedkar National Institute of
Technology, Jalandhar, have developed a process by which bone implant
materials can be synthesised from eggshells.
The research seeks to produce bone substitute
materials such as tricalcium phosphate, a commonly-used bone substitute
material, from natural sources. Eggshells are made of largely of minerals
(95.1%) along with small amounts of proteins and water. Calcium is the main
In modern medicine, damaged and missing bones are
replaced with bone from either the patient or a donor or by using artificial
materials containing calcium, such as Plaster of Paris, and more recently,
phosphate compounds like hydroxyapatite and calcium phosphate.
For their study, researchers synthesised pure and
thermally stable tricalcium phosphate nanopowder — powder a hundred thousand
times smaller than the width of a single human hair — from eggshells. They used
a milling process called ‘ball milling’ to produce these activated calcium
Results showed that eggshell waste is promising
enough to replace the commercially available tricalcium phosphate (produced by
using harmful chemicals) and has the capability to develop implantable
biomaterial for tissue regeneration, according to the research paper published
in Ceramics International .
