Top 10 questions facing plant science research

Plant science has never been more important. It is beginning to address grand challenges, but it is not clear that the full range of challenges facing plant science is known or has been assessed. What questions should the next generation of plant biologists be addressing?

Theses are the top ten investigatory project ideas in plant science.

How do we feed our children’s children? 

By 2050 the world population will triple and demands energy intensive foods such as meat and dairy. Meeting these demands over the years

Investigatory project on Cathode materials for rechargeable magnesium battery

Chevrel phases such as Mo6S8 are the cathode materials with good cycles for rechargeable magnesium battery which Prof. Aurbach announced in 20001. In case of sulfide and selenide compounds, the discharge voltage is around 1 V (see figure 1 below) which is much lower than those (above 3V) for Li ion battery cases. It is expected that Mg2+ is difficult to diffuse in cathode materials due to the

Environmentally responsible dye application in textile

Environmentally responsible dye application involves the principles of pollution prevention that were developed and promulgated in the early 1990s with the hierarchy of ‘reduce, reuse, recycle’

Successful dyeing depends on achieving the following as efficient as possible.

  1. The correct shade
  2. Level dyeing
  3. Fastness

Issues of environmental responsibility are thus encountered in trying to achieve each of the basic requirements of shade, fastness, levelness and efficiency. Holding fewer dyes in stock may be more efficient, and selecting dyes that are considered more environmentally benign might be environmentally responsible, but reduced dye choice may make a level, fast or non-metameric match harder to achieve. The efficient use of

Low Carbon Island 1ton CO2/capita/yr challenge-Cayman Islands

Cayman Islands import nearly all of oil and electricity from neighboring countries. Tourism accounts the larger share of the service sectors followed by insurance, banks and mutual funds. It has been identified that electricity generation and transportation consume major share of oil usage in the country recently. Renewable energy solutions including solar thermal, PV, wind, biofeuls development has been studied to determine their energy and CO2 emission reduction potential. Models of energy systems and their optimization have been carried out using HOMER and the total investment required and the feasibility has also been dealt with.


Energy scenarios

To determine the energy demand by 2030 and thereby estimate the CO2 emission per capita alternative energy scenarios can be developed; the business as usual (BAU) scenario and

Potential bioenergy options in developing and developed countries and their possible impact:PART ONE

Bioenergy is physical energy extracted from biomass. It can be electricity produced from biomass, cooling or heating, biofuels such as biogas, bioethanol, biodiesel and so on. It is an environmentally friendly, cost-effective and locally available source of energy. Developing countries can be benefited from these resources in creating income and labor opportunities, alleviating food security problems and poverty. In developed countries, bioenergy contributes a lot in reducing oil dependency and boosting their economy.

Agricultural energy crops

In the united sates, short rotation woody crops and herbaceous crops have attracted attention. Willow, eucalyptus is examples
