    How do you power billions of sensors? By converting waste heat into electricity

    Interconnected healthcare and many other future applications will require internet connectivity between billions of sensors. The devices that will enable these applications must be small, flexible, reliable, and environmentally sustainable. Researchers must develop new tools beyond batteries to power these devices, because continually replacing batteries is difficult and expensive.

  • Nigerian Youth Have Gone To Sleep? By Tao Bakare

    Nigerian Youth Have Gone To Sleep? By Tao Bakare

    Nigerian Youth Have Gone To Sleep? By Tao Bakare 1

    Nigerian Youth Have Gone To Sleep? By Tao Bakare 2


    Woke up this morning to the unfortunate reality of the Nigerian state, the failure of her youth to take up responsibilities as the thread and wool that holds her fabric together.
      
    Flashback to the time when our past heroes, who were at the time youths, took up giant strides and went through the battles, upheavals, fights that ensured the liberation of the Nigerian state.
     
    In the nineties, Nigeria was lucky to have the likes of Chinua Achebe, Wole Soyinka, Fela Anikulapo Kuti, Gani Fawehinmi, Femi Falana amongst others responsible for the many historical and  ground-breaking achievement through measures of journalism, arts, literature and activism amongst others.
      
    Unfortunately, today, the reverse is the case, as we now have illiterates, educated hypocrites and mediocres that make up over sixty five percent of the Nigerian population.
      
    However, the blame cannot solely lie on the youths themselves, as it is loud enough that our leaders whom we entrusted our future unto have failed woefully to deliver in this respect. But also, it is noteworthy that the youths themselves have not helped to correct the anomalies, but have glaringly resolved to fold arms and watch their own future rubbed in the mud.
     
     In the Nigeria of today, youths have been relegated to the position of back benchers, applauding mammoth and mere on Lookers in the running of state affairs, which they ought to be at the fore front, as in the times of the West African Students Union, when students, youths, led liberation movements across Africa, and also saw to the independence of West African states.
     
    Obviously, it is crystal clear that youths, who occupy the largest percentage of Nigeria’s population now see themselves and thus submit to our doomed leaders, as election thugs, political hallelujah boys, political assassins and trash can. Instead of them to look ahead, beyond ethic bigotry and difference, it is unfortunate they now lead ethnic hate discussions and debates both online and offline, in turn, parading themselves as useless ‘ leaders of tomorrow’. I wonder how this country will pay it’s debts in the next twenty years, with this kind of bad debtors in town, the so called youths.
     
    In a sane society, the youths should be the ultimate institution of political accountability and policy partner to the government, thereby, holding erring leaders accountable. Also, youths should serve as the rebranding tool for a collapsing or collapsed entity, like ours.
      
    Recently, the chief of police, ordered for the disbandment of zonal SARS in Ogun State following the death of a  promising young man, Tiamiyu Kazeem popularly known as Kaka, who until his death was the Vice Captain of Remo Stars Football Club.
       
    The order of the IGP, came, not only regarding the fact that the young man who was the victim of yet another SARS menace, was a known football star, but also because the youths in Sagamu community flaunted their power as youths!
      
    Moral of this recent case and it’s achievement, is that, so much can be achieved if youths wake up from their long mouth drooling slumber and take full responsibility for their own future.
      
    Nevertheless, if they fall to do this, I fear they may sleep and never wake up.

    The time To Take It Back is now!

    A student of the University of Agriculture, Abeokuta, who was expelled for writing an open letter to the school’s management over issues of transportation and insecurity on campus, Ifemosu Michael Adewale, has raised the alarm over plans to kill him.

    In a petition written to President Muhammadu Buhari, Ogun State governor, Dapo Abiodun, and heads of law enforcement agencies in the country, Adewale alleged that Vice Chancellor of FUNAAB, Prof Felix Salako, was currently doing everything possible to kill him.

    According to the young man, he had been receiving death threats from different persons, who have told him that he would suffer for speaking against Salako.

    Adewale said that he was crying out so that the world would know where his death came from in case he was killed.

    He said, “At exactly 1:00am on Tuesday, March 17, 2020, some hired assassins came to my apartment around Apakila Camp with cutlasses and guns. They tore the net of my room and afterwards moved to the last room in my compound, tore the net and started searching for me.

    “When they could not find me, they left but not without warning that they were going to deal with me for fighting the VC.

    “Earlier, I had received a lot of calls from private numbers telling me that they would kill me for challenging my unlawful and illegal expulsion from the university and ridiculing the Vice Chancellor.

    “Prof Salako is close to those in power, whereas I am an ordinary citizen.

    “I am crying out publicly so that at least the world will know where my death came from and I will not join the long list of unresolved murders. My killer should at least be known.”

    But when contacted by SaharaReporters, spokesperson for FUNAAB, Dr Lydia Onwuka, denied the allegations, insisting that the VC, Prof Salako, has no reason to go after the life of Adewale or any other person in fact.

    She said, “There is a matter in court but let me just say that the VC has no reason to kill Ifemosu Adewale or any other person.

    “The allegation is not founded on any proof or fact, so it is not true.”

  • Device brings silicon computing power to brain research and prosthetics

    Device brings silicon computing power to brain research and prosthetics

    Researchers at Stanford University have developed a new device for connecting the brain directly to silicon-based technologies. While brain-machine interface devices already exist—and are used for prosthetics, disease treatment and brain research—this latest device can record more data while being less intrusive than existing options.

  • A strategy to achieve ultrahigh power and energy density in lithium-ion batteries

    A strategy to achieve ultrahigh power and energy density in lithium-ion batteries

    In recent years, lithium-based batteries have become widely used to power a wide range of electronic devices, including tablets, smart phones and portable computers. These batteries have different compartments, called cells, each of which contains a positive electrode and a negative electrode separated by a chemical known as an electrolyte.

    One tough power source: Creating a lithium-ion battery that cannot catch fire

    The popular myth that a spider is never more than a few feet away is arguably more true of lithium-ion batteries than of arachnids. Powering everything from smartphones and laptops to electronic cigarettes, lithium-ion batteries beat out alternative sources of power because of their top-notch energy density and long life cycle, meaning they can be recharged over and over again before breaking down. Yet for all these advantages, lithium-ion batteries come with a major concern: They can catastrophically ignite when they overheat.

    The power of light for internet of underwater things

    A system that can concurrently transmit light and energy to underwater energy devices is under development at KAUST. Self-powered internet of underwater things (IoUT) that harvest energy and decode information transferred by light beams can enhance sensing and communication in the seas and oceans. KAUST researchers are now solving some of the many challenges to this technology being employed in such harsh and dynamic environments.

  • Shedding light on optimal materials for harvesting sunlight underwater

    Shedding light on optimal materials for harvesting sunlight underwater

    There may be many overlooked organic and inorganic materials that could be used to harness sunlight underwater and efficiently power autonomous submersible vehicles, report researchers at New York University. Their research, publishing March 18 in the journal Joule, develops guidelines for optimal band gap values at a range of watery depths, demonstrating that various wide-band gap semiconductors, rather than the narrow-band semiconductors used in traditional silicon solar cells, are best equipped for underwater use.
