The Dhaka Times Desk The Chinese company Betavolt made nuclear energy batteries. The company claims that the life of this battery will be 50 years!
The company is planning to launch this nuclear battery called Betavolt's BV 100 soon. This battery uses nickel-63 isotope and diamond semiconductor material.
Betavolt said they aim to develop these nuclear batteries for use in aerospace, AI devices, MEMS systems, medical devices, AI sensors, small drones and robots. Their ultimate goal is a battery powered smartphone. Such smartphones never need to be charged. After purchasing an electronics product, one can rest assured of charges for 50 years. That being said, this is undoubtedly an incredible event. However, BV 100 production is currently in the pilot stage. Also this battery is not able to provide much charge. This 15x15x5 mm 3 volt battery provides only 100 microwatts of power. Multiple BV 100 batteries can be used together in series or parallel depending on the device requirements.
Betavolt also said it plans to bring a 1-watt version of its nuclear battery to market in 2025.

How to prevent dengue
Dengue is a mosquito-borne viral fever. This fever is different from other viral or bacterial fevers. However, this fever is not contagious in any way. This viral fever can occur alone or in combination with other viruses (chikungunya, yellow fever, Burma forest, flu, respiratory syncytial) and bacteria (pneumococcus).
Dengue fever is divided into two categories depending on the severity of symptoms and fever.
1. Common dengue fever
2. Dengue fever with bleeding.
In the case of common dengue fever, the following symptoms are mainly seen-
1. Sudden high fever lasting 2 to 7 days.
2. Severe headache.
3. Pain behind the eyes.
4. Along with the fever, red rash appears all over the body.
5. Severe pain in whole body as well as back pain.
6. Nausea or vomiting.
7. A rash or red bumps on the skin.
In case of dengue fever with bleeding:
1. Bleeding from nose, mouth or vomiting with high fever within 2 to 48 hours.
2. Fluid accumulation in chest or abdomen along with fever.
If any of these symptoms appear, seek medical attention immediately.
On the other hand
Wait at home for the first 3 days of fever. On the other hand, sponge the whole body with water every now and then. This will reduce the level of fever. Drink enough water and rest. After that, if the fever does not decrease or if it continues to increase after some time, consult a doctor immediately.
Things to do to prevent Dengue:
1. Try to keep the surroundings of the house as clean as possible.
2. If there are flower tubs or broken plastic bottles, can shells, tires or polythene inside the house, clean them quickly and drain the accumulated water from the flower tubs.
3. Spray or fog at least 3 times a week to kill mosquitoes.
4. You can keep mosquito repellent cream with you while going out.
5. After evening, younger and older members of the household should use mosquito nets.
6. Clean up any accumulated rain water, as this is the time when Aedes mosquitoes lay their eggs.
7. On the other hand, you can use mats along with mosquito nets to avoid mosquito infestation.
8. Since Aedes mosquitoes bite during the day, it is important to avoid sleeping with mosquito nets while sleeping during the day. Source: https://dmpnews.org
