 1.       World Sustainable Development Summit in New Delhi

• The World Sustainable Development Summit-2018 (WSDS-2018) was held at Vigyan Bhavan New Delhi.

• WSDS is a flagship forum of The Energy and Research Institute (TERI) which brings global leaders and thinkers in the field of sustainable development, energy and environment together at one forum.

The theme of this year summit is ‘Partnerships for a Resilient Planet’. The forum seeks to create action framework to resolve some of most urgent challenges facing developing economies in backdrop of climate change.

                                                                                     

2.       Asia’s first large scale CO2 injection at Gandhar field

• Oil and Natural Gas Corporation (ONGC) will introduce Asia’s first large scale   carbon dioxide injection in its Gandhar oil field in Gujarat

• The purpose of this injection is to recover extra 20 million barrels of crude oil under enhanced oil recovery (EOR) programme which aims at recovering up to 20% of residual oil from ageing oil fields to improve India’s energy security.

• Gandhar field produces approximately 30,000 barrels of oil per day and is on the decline.

• The CO2 injection technology is used in the ageing field in which total production has been declining. It reduces viscosity and makes it easier to displace oil from rock.

 

3.       TIFR successes in studying electron bunches

• First time in any Indian lab the physicist of Tata Institute of Fundamental Research (TIFR) have succeeded in studying electron bunches, kicked up to high speeds within a glass slab by a femto second laser pulse.

• The mega sized current pulses of electron cause secondary emissions from their targets, which can be X-rays, ions and the like, which have applications in medicine and imaging technology.

• Such megampere electron bunches are also expected to be used in laser fusion research and how they lose energy there by heating the fusion target is extremely important.

 

4.       Silver silk patch can heal wound

• Scientists have produced a new material by embedding silver oxide nano-particles on silk fibre that can be used to make patches to help in healing of wounds and preventing infection.

• An ideal wound-dressing material should have good thermal insulation and also allow gaseous and fluid exchange in the wound area.

• The new material using silver dioxide is able to maintain the moisture and has ideal water holding capacity. Further, it was able to heal scratch wounds completely in 24 hours and also kill pathogens like S. aureus and M. tuberculosis.
