The professor of chemistry and vice-dean of the Faculty of Physical and Computational Sciences at Kwame Nkrumah University of Science and Technology (KNUST), Prof. Nathaniel Owusu Boadi, has highlighted the significant impact that nanotechnology can have in promoting sustainable energy solutions in Ghana and throughout Africa.
During his Professorial Inaugural Lecture at KNUST, Professor Owusu Boadi highlighted that nanotechnology—which is frequently called ‘the science of the unseen’—is crucial for developing more effective, cost-efficient, and environmentally friendly energy solutions.
His lecture, titled
‘Heading towards inclusive renewable energy for everyone: utilizing the force of the unseen titans,’
tracked the development of nanomaterials from their early beginnings through to their advanced uses in contemporary energy solutions.
As he points out, nanotechnology has the potential to greatly boost the effectiveness of solar cells, increase battery efficiency, and refine fuel cell technology—elements crucial for shifting towards a more sustainable and robust energy industry.
“Even though Ghana and numerous African nations receive ample sunlight, access to solar power stays restricted because traditional silicon-based photovoltaic cells come at a steep price. However, nanomaterials present an encouraging substitute that might reduce expenses and boost effectiveness, thereby increasing the availability of solar energy,” he pointed out.
Professor Owusu Boadi urged the government to significantly increase investment in researching and developing nanomaterials for energy production.
He similarly called upon regulatory entities like the Environmental Protection Agency and the Ghana Standards Authority to develop scientifically grounded safety protocols for manufacturing, utilizing, and disposing of nanomaterials—ensuring these align with global best standards.
He also suggested forming a National Nanotechnology Research Center, which would be led by the Ministry of Environment, Science and Technology (MEST), working alongside the Ministry of Finance, educational institutions, and representatives from various industries.
He clarified that this center would promote locally developed innovations and help bring nanotechnology-based energy solutions to market, specifically addressing Ghana’s requirements.
Professor Owusu Boadi further emphasized the extensive uses of nanotechnology outside the realm of energy. Within the medical field, nanomaterials aid in early detection via improved diagnostic imagery and assist in regenerating tissues.
In environmental science, these applications are employed for purifying water and cleaning up hazardous waste. Additionally, the electronics sector benefits from more efficient semiconductors, as well as precise sensors; meanwhile, the textiles industry profits from smarter and antimicrobial fabrics.
Moreover, Professor Owusu Boadi noted that although Ghana has achieved significant progress in electrification with an 85.1% access rate as of 2022, numerous rural areas continue to struggle with unreliable power supply.
In Sub-Saharan Africa, approximately 600 million individuals still lack access to electricity. He stated that this disparity represents not only a challenge but also numerous opportunities.
“Through investment in nanotechnology, Ghana has the potential to spearhead the creation of sustainable, domestically-generated energy solutions. These efforts could not only bridge this gap but also establish the nation as a center for environmentally-friendly innovation,” he highlighted.

Scientists identified a torus-like area at the upper boundary of the outer core.
-
This less dense area aids in agitating the molten metal, thereby producing the magnetic field.
Researchers have discovered an enormous ring-like formation hidden deep below the surface.
Scientists from the Australian National University utilized seismic waves created by
earthquakes
to gaze into the Earth’s enigmatic liquid center.
By following the trajectory of these waves throughout the Earth, scientists discovered a layer approximately hundreds of kilometers deep where their speed decreased by two percent compared to usual.
The doughnut-shaped formation encircles the Earth’s liquid outer core along an equatorial path, potentially playing a key role in generating our planet’s shielding magnetic field.
Professor Hrvoje Tkalčić, who led the research, states: “The magnetic field is an essential component required for sustaining life on Earth’s surface.”
Our planet consists of four primary layers.
the exterior crust, the partly molten mantle, a fluid metallic outer core, and a solid metallic inner core.
![]()
When the movement of tectonic plates in the crust creates earthquakes, these produce vibrations that spread out through all the other layers of the Earth.
Leveraging the global network of seismic monitoring stations,
Scientists can observe how the waves propagate and use this information to forecast the circumstances beneath the water’s surface.
Researchers typically focus on the large, strong wavefronts that circulate globally within the initial hour following an earthquake.
Nevertheless, Professor Tkalčić and his co-author Dr. Xiaolong Ma managed to identify this pattern by examining the subtle remnants of waves that persisted for several hours following the primary shock.
The technique demonstrated that seismic waves propagating close to the poles were traveling at a quicker pace compared to those nearer to the equator.
When they compared their findings with various models of the Earth’s interior, Professor Tkalčić and Dr Ma discovered that these observations were most accurately described by the existence of an extensive subterranean ‘torus’, essentially a doughnut-shaped area.
They forecast that this area is located solely at low latitudes and aligns with the equator close to the upper boundary of the outer core, where the liquid part interfaces with the mantle.
“We aren’t certain about the precise thickness of the doughnut, but we deduced that it extends several hundred kilometers below the core-mantle boundary,” states Professor Tkalčić.
Due to the vital importance of this area, their discovery might also hold significant consequences for understanding life on our planet and beyond.
The Earth’s outer core extends about 2,160 miles (3,480 km), which is somewhat bigger than the size of Mars.
Primarily composed of molten nickel and iron, convection currents combined with the planet’s spin drive the fluid metals in this region into elongated vertical whirls oriented from north to south, similar to colossal water tornadoes.
The rotating flows within these molten materials function akin to a dynamo, generating the Earth’s magnetic field.
As this donut-shaped area has risen to the upper part of the liquid outer core, it implies that it might contain an abundance of lighter elements such as silicon, sulfur, oxygen, hydrogen, or carbon.
Professor Tkalčić states: “Our discoveries are intriguing as this reduced speed within the liquid core suggests a significant presence of lightweight chemical elements in those areas, which would consequently decelerate the seismic waves.”
These lightweight components, along with variations in temperature, assist in agitating the fluid within the outer core.
Without that vigorous movement to power the planet’s internal dynamo, Earth’s magnetic field may not have come into existence.
In the absence of the magnetic field, the planet’s surface would face an unrelenting assault from charged particles.
From the sun, which has the power to damage the genetic material of living organisms.
This ring-like area could thus be an essential clue in understanding how life originated on Earth and what signs we should search for when identifying potentially livable exoplanets.
Dr. Tkalčić concludes: “Our findings might encourage further investigation into the magnetic fields of both our planet and others.”
