Researchers at Duke University, USA, have developed tiny nanoparticles that help convert CO2 into methane using an ultraviolet light as an energy source. The team now hopes to develop a version that would run on natural sunlight, a potential boon to alternative energy.
Xiao Zhang, a graduate student at Duke University, synthesised rhodium nanocubes that were the optimal size for absorbing near-ultraviolet light. He then placed small amounts of the charcoal-colored nanoparticles into a reaction chamber and passed mixtures of carbon dioxide and hydrogen through the powdery material. Upon heating the nanoparticles to 300°C, the reaction generated an equal mix of methane and carbon monoxide. Zhang then turned off the heat and illuminated them with a high-powered ultraviolet LED lamp, resulting in a reaction between the carbon dioxide and hydrogen at room temperature to produce methane.
The team plans to test whether their light-powered technique might drive other reactions that are currently catalyzed with heated rhodium metal. By tweaking the size of the rhodium nanoparticles, they also hope to develop a version of the catalyst that is powered by sunlight, creating a solar-powered reaction that could be integrated into renewable energy systems.
It is not your job to manage how other people can handle you. It is not your job to make sure that people can digest your greatness and that you your light isn’t shining so brightly that it is blinding others. That’s not your job. Your job is to let your light shine brightly. Your job is to be obedient to your calling. Your job is to be so committed to the luminary light in you that when you allow your light to shine bright it illuminates the next person’s darkness.
This is a meditation I made that I found to be extremely deep and powerful. Use it when you feel you need some balance or beneficial energy in your life, or just need to sit and meditate in general. It is also good for opening the third-eye. I find that this meditation gives many sensations which can be pretty intense, so don’t be alarmed if you feel things very strongly. Just relax, go with it, and you’ll be ok. You’ll need about a half-hour for this procedure.
1. Sit in a comfortable position (preferably cross-legged) and keep your back straight, with your chin tilted slightly downward. Put your hands in your lap with the palms facing up, with right over left for females, and left over right for males.
2. Take a few minutes to breathe deeply and relax your muscles. Gradually slow your heartbeat down, and begin to clear yor mind. Block out the surrounding world, and focus on your breathing. Focus on the present. Begin breathing more slowly and deeply, in through the nose, out through the mouth. Close your eyes.
3. Gently bring your attention to the root chakra, located near the privates. Visualize this chakra as a red, swirling point of energy or light. Try to breathe ‘into’ and ‘out of’ this point, directing your breath to the location. As you inhale, imagine clean, beneficial energy entering the chakra, making it brighter and more vivid. This should look something like when an ember from a fire is blown on and it glows. As you exhale, imagine any unhelpful or unclean energy leaving and dissipating, again making the chakra more bright and vivid. Feel this energy exchange as you do it. After repeating for as long as you feel is necessary, move to the next chakra.
4. Continue this process for each chakra, all the way up to the crown. As you move up, you may feel a sense of your conciousness ‘changing shape’. You may also feel vibrations in certain parts of the body (especially the crown), feel numbness and tingling in the face and limbs, see flashes or swirls of light, have a floating or disconnected sensation, or hear ringing in the ears.I find that these start to get very intense at throat chakra, and reach its peak at the crown. Remember that this is normal and will not harm you in any way.
5. When you finish the crown chakra, take a minute to just breathe and prepare for the next step. When ready, imagine a stream of white or pearly light going from the crown chakra all the way down to the root chakra. Feel and see this energy hit each point as it travels down.
6. When the stream of light reaches the bottom, imagine it climbing its way back up starting from the root chakra. Go slow this time, and really feel it work its way back up to the crown. Imagine it reaching and filling each chakra as it goes along. Tune into the vibrations it gives each chakra.
7. When you reach the crown, imagine that stream of light going up and out into the universe in rays. Feel it open up and spread out above you, connecting you to the universe and its knowledge, strengths and vibrations.
8. Take a couple minutes to just breathe deeply. Relax your muscles, and begin to regain awareness of the world around you. Ground yourself and start to move your fingers and toes. Seperate your hands, put them on your lap, then gently open your eyes. The meditation is now finished.
