MECHANISMS OF DRUG ABSORPTION Most drugs are thought to be absorbed from the gastrointestinal tract by passive nonionic diffusion or by active transport. Other mechanisms such as facilitated transport, passage through membrane pores, and pinocytosis seem to play only a … Continue reading →

Lithium-ion batteries don’t suffer from the memory effect, which means they always give up their last bit of power, and you can recharge them whether you’ve used 100% or 25% of their capacity with no pesky maintenance needed! More charge … Continue reading →

Can lithium batteries be rechargeable? Lithium batteries are primary cell batteries, which means they cannot be recharged once empty. They use the metal lithium as an anode. Lithium batteries have a high charge density, meaning they last longer than other … Continue reading →

Specifically, if you want to fully discharge a typical car battery (12V, 60 A hr), all you need is a 20 ohm, 10 W resistor (or equivalent), and connect it across the battery terminals. Leave it connected for about 4 … Continue reading →

Finding your laptop’s battery can be tricky. To find your battery, look for a small compartment in the bottom of the laptop. Other laptop batteries are located in a hole or door in the side of the computer. Do laptops … Continue reading →

During in-house testing we’re able to pull maximum currents (pushed to its most extreme limits) from each Weego at least four times before recharging; so rest assured you’re covered! How many times can you use a booster pack? Keeping the … Continue reading →

Look at a 5kw solar panel system specifically, you will likely need a battery with a capacity of at least 10kWh, more likely, up to 13.5kWh. Is 5 kW enough to run a house? Is 5kW enough to run a … Continue reading →

Last month, Tesla officially announced the switch of all standard range (entry-level) versions of its cars to the Lithium Iron Phosphate (LFP) battery chemistry globally. You can see an LFP battery used in a Tesla Model 3, presented by Munro … Continue reading →

Like graphite, graphene conducts electricity well because it has delocalised electrons that are free to move across its surface. These properties make graphene useful in electronics and for making composites . Why is graphene better than graphite? Although graphite is … Continue reading →

If the voltage is too low, the amperage increases, which may result in the components melting down or causing the appliance to malfunction. If the voltage is too high, this will cause appliances to run ‘too fast and too high’ … Continue reading →

But this is mainly because lightning and giraffes are both fairly rare. There are only five well-documented fatal strikes on giraffes between 1996 and 2010. With a global giraffe population of around 140,000 in that period, this is about 0.003 … Continue reading →

Specific energy or massic energy is energy per unit mass. It is also sometimes called gravimetric energy density, or just energy density though energy density more precisely means energy per unit volume. What do you mean by energy density? In … Continue reading →

How to calculate power density easily – Even in your head! Convert the diameter to cm, Divide the diameter by two to find the radius, Use πr^2 to find the area in cm^ And, finally, divide the laser power by … Continue reading →
