Combining these medications can increase the risk of a rare but serious condition called the serotonin syndrome, which may include symptoms such as confusion, hallucination, seizure, extreme changes in blood pressure, increased heart rate, fever, excessive sweating, shivering or shaking, … Continue reading →

Conclusions: Life expectancy in bipolar disorder is decreased substantially, but less so than previously reported. Patients start losing life-years during early and mid-adulthood. Why does bipolar shorten your life? Possible reasons for the decrease in longevity are many. The most … Continue reading →

First, pour some graphite powder into a blender. Add water and dishwashing liquid, and mix at high speed. Congratulations, you just made the wonder material graphene. This surprisingly simple recipe is now the easiest way to mass-produce pure graphene – … Continue reading →

Avoid drinking alcohol or using illegal drugs while you are taking lithium. They may decrease the benefits (e.g., worsen your condition) and increase adverse effects (e.g., sedation) of the medication. Avoid low sodium diets and dehydration because this can increase … Continue reading →

Yes, you can use any battery pack without a bms. But, you must then monitor it yourself if you don’t want to damage it. If all cells in your pack are equal. then in theory all you need to do … Continue reading →

Natural abundance Most lithium is currently produced in Chile, from brines that yield lithium carbonate when treated with sodium carbonate. The metal is produced by the electrolysis of molten lithium chloride and potassium chloride. How was lithium originally formed? While … Continue reading →

Really, Good Battery for the Price I have been using one of these batteries for over a year and I have never had any problems and the battery works really well powering the fridge and an inverter for battery charging … Continue reading →

The main problems include risks of fire, and that EVs are not safe. There is the case of too much high-tech wizardry, charger compatibility, vehicle costs, and financing of charging stations, just to name a few. What is the biggest … Continue reading →

Instead of charging your phone, tablet, or another device from a wall outlet, you charge it from the power stored in the portable charger by inserting the charger (or charger cable) into the device that needs power. Given the short … Continue reading →
