Water purification with fruit peel . A simple process turns fruit waste into water purifiers.
Water purification with fruit peel
Solar devices are smart and simple devices for purifying dirty or salty water, but they work at a relatively slow speed. It is now known that adding a new ingredient increases their performance. This material is made from fruit waste, which is thrown away if not used.
A typical solar water purifier, in its most basic form, consists of a pool of non-potable water under a transparent cover. Water evaporates when heated by the sun and condenses on the inner surface of the coating. The vapor condensation of pure and clean water in liquid form drips from the surface and collects in a separate container for drinking.
In order to heat dirty or salty water more quickly, scientists have created materials that float on the surface and convert sunlight into heat, and while these materials are made of various compounds, they are typically made of carbon. It comes from coal.
Edison Ang, an assistant professor at Nanyang Technological University, Singapore, and his colleagues were looking for a cheaper and more environmentally friendly alternative that does not require extraction, is free to obtain, and can be disposed of when not in use, and this option is fruit waste. Specifically, scientists tried coconut husks, orange peels, and banana peels.
In a simple two-step carbonization process, fruit waste was heated at 850 °C for several hours and mixed with a molybdenum reagent. By doing this, the scraps were transformed into two-dimensional molybdenum carbide sheets, which belong to a family of metals known as MXenes. Maxins are hydrophilic and have a very high light-to-heat conversion efficiency.
When the compound was tested in a small solar device, the molybdenum carbide square sheets were very effective at converting sunlight into heat, causing the simulated seawater to evaporate much faster than otherwise. Since this material is very porous, water vapor droplets were able to rise directly above it and condense inside the casing of the device.
Materials obtained from coconut shells performed best, as they converted sunlight into heat with an efficiency of 94%.
Professor Ang and his team are now developing the technology further and are looking for industrial partners to help commercialize it.

Leaving the Earth’s atmosphere is not just the experience of floating in the environment. There are also other amazing and troublesome events that can only be experienced in space. In this article, we will talk about the strangest things that can happen to humans in space.
The strangest things that can happen to humans in space
When it comes to space and astronautics, we all remember very interesting movies in which strange things happen to astronauts. Movies with exciting stories, most of which are nothing but the authors’ imaginations; But there are other very amazing stories happening in space that are completely real and have nothing to do with human imagination. In this article, we try to discuss some examples of these events and introduce you to the wonders of space travel.
Strange things that happen to humans in space
The human heart changes shape in space
It may seem a bit strange and even unbelievable that traveling to space can change the shape of the heart, But such a thing happens in reality and scientific studies have proven it. Less work of the heart and less pumping of blood leads to a decrease in the volume of the muscles of this organ, and this ultimately causes the hearts of astronauts to become more spherical by about 9.4%.
Despite the temporary nature of these conditions, some doctors believe that the reduction in the volume of the human heart during space travel may have serious consequences. According to NASA, researchers are researching this issue, and the results of this study will not only help astronauts but will also affect ordinary people and the inhabitants of the planet.
There is a possibility of mental problems in space
Living in the extraterrestrial atmosphere is associated with many problems. Changing living conditions and experiencing a completely different environment with very specific conditions imposes many psychological pressures on astronauts. These issues cause astronauts to experience special psychological conditions and are susceptible to various problems such as anxiety and depression.
Being away from family, lack of simple facilities such as sunlight or even fresh food, and heavy work are among the reasons that expose astronauts to various mental illnesses.
Human vision decreases in space
Visual impairment caused by intracranial pressure or VIIP is another space travel wonder faced by astronauts. This problem was observed for the first time in 2005 and in an astronaut named John Phillips. The Washington Post investigates this issue in an article and states that Phillips experienced a significant loss of vision after returning from his space trip. This incident prepared the groundwork for the researchers’ research for further investigations.
Additional research showed the changes in the appearance of the astronauts’ eyes and the loss of their vision after returning from space travel. Currently, the only possible reason that has been proposed for the occurrence of such conditions is the lack of gravity and the creating double pressure on the astronauts’ skulls; Of course, the research in this field continues and it is still not possible to say with certainty a specific reason for the occurrence of these conditions.
Traveling to space, along with its excitement and surprises, also brings many problems for humans. One of these problems is the weakening of the body’s immune system in space, which was first discovered by astronauts during the Apollo mission. The story was that the astronauts in this mission experienced problems such as irregular heartbeat, dehydration, and inner ear disorder, and faced many problems after returning from the mission.
Studies conducted in this field have shown that after leaving the Earth’s atmosphere, the immune system of astronauts weakens, in part due to the abnormal activation of a type of immune cells called T-regulatory lymphocytes. This weakening is sometimes so severe that it causes astronauts to deal with latent viruses such as chicken pox in addition to simple infectious diseases such as colds after returning from space travel.
Astronauts can lose their fingernails
As you know, astronauts wear special clothes to carry out their missions in space, which includes astronaut gloves. These gloves are designed in such a way that they put a lot of pressure on the astronauts’ hands and nails; This will eventually lead to their nails falling off.
It is true that the fall of fingernails or their swelling is not a simple matter that can be easily passed over, But it seems that doing more research to design more suitable gloves can minimize the possibility of this problem and astronauts will not face such a problem in the future.
Human height grows taller in space
Another wonder of space travel, which makes it one of the favorite trips of ordinary people, is the increase in height that occurs during this trip. As soon as you leave the Earth’s atmosphere, the gravity is close to zero, and this causes the pressure on the spine to decrease significantly. The reduction of this pressure, in turn, causes the height of the astronauts to grow a few centimeters.
One of the studies that confirms the truth of this issue is the research that NASA scientists conducted on two twin brothers. In this study, one of the twins had a 342-day trip to space and the other brother was examined on Earth. The results of this and other research determined that the height of astronauts increases by 2 to 5 cm on average after space travel.
Mark Kelly (left) and Scott Kelly (right) made it possible for researchers to study the health effects of long-duration space travel by studying NASA twins.
Traveling to space leads to weakening of muscles
Another strange thing that happens to astronauts in space and affects their health is the weakening of muscles or atrophy. Long space travel causes muscle wasting in astronauts, so they are trained to exercise continuously during their journey.
NASA is working on this issue to find solutions to prevent the problem of muscle wasting. The reason for the importance of this issue is the need for astronauts to have strong muscles and a healthy body so that they can perform their difficult missions in space in the best possible way.
Space swells astronauts’ faces
A large volume of our body is made up of liquid. On Earth, gravity pulls this fluid down and collects some of it in the lower limbs; But in space, where microgravity prevails, our body fluids are more evenly distributed; As a result, astronauts’ faces look puffier than normal, and on the other hand, their legs appear thinner than when they are on Earth.
According to the Washington Post, “the phenomenon of puffy-faced bird’s legs” appears when blood and other body fluids accumulate on the side of the upper body due to low gravity and stay there; As a result, the heads swell and the legs shrink. In this situation, the appearance of the astronauts can change by swelling their faces. Astronauts may experience excessive blood pooling; As if their head is constantly cold. However, after a few weeks in space, your body will adjust to the change in gravity and some of the facial puff will fall asleep.
Space travel may increase the risk of cancer
Astronauts who spend 6 months in space are exposed to almost as much radiation as a thousand chest X-rays. Exposure to different types of radiation exposes the body to the risk of cancer, damage to the central nervous system, bone loss, and some cardiovascular diseases. However, it has been difficult to accurately calculate the level of risk so far. Also, scientists’ information about the impact of radiation in long-duration space missions to deep space destinations such as the Moon and Mars is still limited.
The more time a person spends in space, the more radiation they are exposed to and, theoretically, the more DNA damage they accumulate. It is not possible to say with certainty whether this DNA damage actually increases the risk of cancer; Because cancer is affected by many environmental and genetic factors. For example, it’s probably fair to say that today’s astronauts are probably some of the fittest people on the planet. They probably eat a healthy diet, exercise a lot, and don’t smoke or drink much alcohol. All these things reduce the possibility of getting cancer.
Strange events for astronauts during space travel have always been one of the most fascinating topics for ordinary people. The wonders of space travel are not limited to the things we have mentioned, and at the same time as science advances and the scope of research increases, we will definitely see more interesting news in this field in the near future.
Reviews of Motorola Edge 50 Ultra phone, price, technical specifications, design, screen, software, hardware, battery life and charging, and other specifications of this phone.
Motorola Edge 50 Ultra review
The Motorola Edge 50 continues to grow today with new additions to the lineup. After launching the Edge 50 Pro earlier this month, the OEM is now introducing the Edge 50 Ultra and Edge 50 Fusion. As expected, the Ultra is at the top of the range, while the Fusion is the most affordable of the three.
We will take a closer look at the Edge 50 Ultra and its flagship features. After all, this is Motorola’s top-of-the-line smartphone for 2024, and it offers a ton of premium features, including AI capabilities and a Pantone-calibrated display and cameras for more accurate and vivid color reproduction.
Motorola Edge 50 Ultra specifications at a glance:
Body: 161.1 x 72.4 x 8.6mm, 197g; Victus gorilla glass front, acetate back (wood based) or silicon polymer back (vegan leather), aluminum frame; IP68 dust/water resistant (up to 1.5m for 30 minutes).
Display: 6.70 inch OLED, 1B color, 144Hz, HDR10+, resolution 1220x2712px, aspect ratio 20.01:9, 444ppi.
Connectivity: 5G; two SIM cards; Wi-Fi 7; BT 5.4; NFC, UWB, USB-C 3.1 Gen 2 with DP 1.4 support.
Other specifications: fingerprint reader (under the display, optical); stereo speakers; Ready to support 6.
AI functions are possible thanks to the new Qualcomm Snapdragon 8s Gen 3 chipset, which sits between last year’s Snapdragon 8 Gen 2 and this year’s Snapdragon 8 Gen 3. while maintaining a relatively low price. Motorola seems to be looking for a more affordable flagship segment.
But despite the small agreement in the chipset department, Motorola does not make cameras, displays and chargers. The 6.7-inch OLED panel packs all the punch, runs at up to 144Hz and can charge up to 125W (wireless is 50W). The camera hardware looks good on paper. We’ve got a 50MP main sensor assisted by a 50MP ultra-wide unit and a 64MP 3x telephoto camera with a reliable f/2.4 aperture. Even the selfie unit is 50MP with autofocus, which is rare even in the ultra-premium segment.
Designing
The overall design language of the Edge 50 Ultra follows the Edge 50 family, and since the screen is the same as the Edge 50 Pro, the two phones feel the same in the hand. The Ultra comes in two variants – with a vegetable leather or wooden back. The latter is a bold approach, but will likely appeal to some.
Available colors include Forest Gray and Peach Fuzz (both vegetable leather options) and Nordic Wood (pictured below).
Of course, the wooden back is not pure wood. Motorola has used a special coating for the surface that preserves the wood-like texture while protecting it from water and oil, so it doesn’t change color or lose its appearance. Either way, the imitation is pretty good – almost like real wood.
The Edge 50 Ultra and the Edge 50 Pro look so similar that it would be hard to tell them apart if they both had plant-based leather. Camera hardware ditches the Edge 50 Ultra, as the telephoto uses a periscope lens and the round LED flash is replaced by a smaller, vertical flash.
Motorola Edge 50 Ultra vs Edge 50 Pro
The front and back panels are still rounded, which helps with grip, and to be honest, the wooden back is easier to hold. It also brings back a distant memory of Motorola’s Moto X in 2013 with its bamboo and wooden back.
The side frame is still aluminum, while the front glass is Gorilla Glass Victus. And for a 6.7-inch device with this many cameras, the weight gain at 197 grams is pretty impressive. Leather and wood are lighter than glass, so that could be an explanation.
As expected from a high-end smartphone like the Edge 50 Ultra, the device has IP68 ingress protection.
Hardware
The Edge 50 Ultra and Pro have very similar hardware for the most part, but as we mentioned earlier, the Edge 50 Ultra has a more powerful Snapdragon 8s Gen 3 chip that delivers flagship-level performance and features. One notable limitation is the chipset’s inability to record 8K videos. 4K is capped.
Motorola Edge 50 Ultra vs Edge 50 Pro
The curved OLED panel is a small step above the competition in terms of refresh rate, as the Edge 50 Ultra’s 6.7-inch display supports a 144Hz refresh rate. It remains to be seen whether Motorola has been able to make the best use of the display’s capabilities.
In addition to the 144Hz refresh rate, the panel also has support for HDR10+, 10-bit color depth, and DC dimming for those who might be sensitive to regular PWM dimming. It can also push up to a maximum brightness of 2,500 nits, but we suspect this will be achievable in small patches during HDR video playback.
For a complete multimedia experience, Motorola has put more effort into the speakers as well. They are tuned by Dolby Atmos and support Dolby Head Tracking.
A fairly average 4,500 mAh battery keeps the lights on, but capacity isn’t everything. We’ll see if Motorola’s hardware and software tweaks can compensate for the smaller-than-usual battery pack. It is good that Edge 50 Ultra is equipped with 125W wired charging and 50W wireless charging.
The Motorola Edge 50 Ultra also has two significant hardware advantages over some of its competitors. It supports ultra-wideband connectivity (a feature only seen on a handful of Android smartphones) and USB 3.1 gen 2 with DisplayPort 1.4 compatibility. It works well with Motorola’s Ready For desktop environment.
Software
Of course, the Edge 50 Ultra runs on the latest Android 14 with Motorola’s own features. Motorola offers productive AI capabilities for wallpaper customization purposes, but other than that, AI is almost non-existent in Motorola’s current software.
However, the OEM insists on implementing system-wide AI algorithms that work in the background. AI-based algorithms are supposed to optimize performance, battery life, and search.
Camera
Undoubtedly, one of the main features of Edge 50 Ultra is its camera. Motorola hosted a special press event in Morocco where we had a chance to try out the pre-production Motorola Edge 50 Ultra unit along with the rest of the Edge 50 lineup. The camera samples here were all taken over the course of a day at locations and events organized by Motorola.
Front camera: 50 MP, f/1.9, 1.28 µm, AF. 2160@30fps
When it comes to camera hardware, the Ultra stands out in the Edge 50 family with a total of four powerful cameras. The main camera uses a large 50-megapixel 1/1.3-inch sensor with a wide f/1.6 aperture and stabilized optics.

The 64-megapixel telephoto camera has a 3x optical zoom and f/2.4 aperture.

And the secondary secondary camera is a 50-megapixel ultra-wide unit with a wide 122-degree FoV, f/2.0 aperture, and autofocus support for macro shots.

The selfie camera is impressive, at least on paper, with a 50-megapixel resolution, f/1.9 wide aperture, and autofocus support. It’s 2024 and we hardly ever see phones with AF-equipped selfie cameras, so kudos to Motorola for adding this feature.
Selfie photos
But not only the hardware of the camera itself, its software features and optimization as well. Although AI isn’t the main focus on the software side, Motorola benefits greatly from AI-based camera optimizations.
Let’s start with the action shot. The camera software automatically increases and adjusts the shutter speed in low-light environments to minimize motion blur. We did a brief test of the feature and found that in some cases, the shutter speed went from 1/50 to 1/200, while at the same time, the ISO doubled from 3100 to 6200. This is without any significant increase in noise thanks to the AI-based noise reduction algorithm. Here is a short example.
Examples of action shots
Adaptive stabilization works in video mode and dynamically adjusts the level of stabilization based on your hand movement and scenario.
Autofocus tracking is another video-based feature that improves the sharpness of footage from subjects moving quickly through the frame. This one will be available with the next update.
It’s worth noting that Motorola offers a choice between natural and auto-enhanced shooting modes, with the former being the default mode. Auto-enhancement mode apparently takes longer to capture images, but we didn’t notice a slowdown when using it. . Also, this isn’t exactly a Motorola exclusive. This is actually the Auto Enhance feature that we all know from the Google Photos app. Motorola decided to integrate this feature into the camera app for convenience, but the system only saves “enhanced” photos, not “normal” photos.
It’s a bit early to comment on the camera quality as we took samples with the pre-production unit. But before we get a production-ready phone, let’s take a look at some videos taken with all the cameras.
Summary
As always, it’s a little early to say whether the Motorola Edge 50 Ultra is a good buy or not, but it’s certainly a promising one. The phone has all the features of a true flagship phone, while the price starts at €999, which is considered affordable in today’s flagship segment. Over time, the price will come down and the phone will become a more attractive option.
In any case, despite the promising hardware, the full review will reveal whether the 4,500 mAh battery is enough for reliable endurance, and it will be interesting to see how the new camera system stacks up against the competition. The Moto Edge 50 Ultra is expected to hit the market by the end of May, and a lot can change between now and then.
