HAVANA, Sept 16 (Reuters) – Developing nations on Saturday declared Sept. 16 the annual “Day of Science, Technology and Innovation in the South” as they prepared to wrap up a two-day summit on the subject.

“We note with deep concern the existing disparities between developed and developing countries in terms of conditions, possibilities and capacities to produce new scientific and technological knowledge,” the final declaration of the G77 group of developing nations and China said.

“We call upon the international community, the United Nations System and the International Financial Institutions to support the efforts of the countries of the South to develop and strengthen their national science, technology and innovation systems,” the organization, which now counts 134 countries, stated.

The statement cited the pandemic and

EXPLAINERS

A look at the characteristics of solid-fuel technology and how it can help North Korea improve its missile systems.

North Korea says it has successfully tested a new solid-fuel intercontinental ballistic missile (ICBM), its first known use of the propellant in a longer-range projectile.

But what exactly is a solid-fuel missile and why does it matter to have one?

What is solid-fuel technology?

Solid propellant is a mixture of fuel and oxidiser. Metallic powders such as aluminum often serve as the fuel, and ammonium perchlorate, which is the salt of perchloric acid and ammonia, is the most common oxidiser.

The fuel and oxidiser are bound together by a hard rubbery material and packed into a metal casing.

When the solid propellant burns, oxygen from the ammonium perchlorate combines with aluminum to generate enormous amounts of energy and temperatures of more than 5,000 degrees Fahrenheit (2,760 degrees Celsius), creating thrust
