Still too slow, India should had opened hundreds of electric charge stations by now and the Eco system of electric cars along, and not just open one every year.

Cost of Elements:
(Ordered from $$$ to $)

Cobalt [Co] = $30 / Kg
Nickel [Ni] = $15 / Kg
Manganese [Mn] = $2 / Kg

Properties:
Cobalt + Oxygen = locks the lithium in place, and avoids dendrite growth greatly, and very stable

Nickel = Boosts energy density

Manganese = Reduces degradation of battery significantly

Types of Li Ion battery chemistry:
(Ordered from $$$ to $)

Li + Co + O [Oxygen/Oxide] = LCO
Li + Ni + O = L-NO
Li + Mn + O = L-MO

Li + Co + Ni + Mn + O = L-CNM [Used in smartphone]
Li + Co + Ni + Al + O = L-CNA [Used in Tesla cars]

Father of all suspension -> Electromagnetic suspension.

I hope decent amount of time is invested in modernizing and incorporating this technology in future cars.

2 Questions.

1. Are women allowed to drink in Iran ?
2. He can marry up to 4 wife according to his country statute, then how is it called Cheating ?

If it's wrong, law should be enacted to ban polygamy or polyandry.

Conversion is done and forced in every religion [Hindu / Muslim / Christian etc],
person / family with the powerful status, tries to convert the bride/groom to their native religion,

These types of practices will only pave way to problematic and peaceless life between couples,
If the couple [Male/Female] are not ready to accept their partner and their way of life as it is rather than converting them and renaming them, they shouldn't had loved them in the first place !!

For these types of problem, the standard procedure should be [law should be created],
Couple [Male/Female] should not be allowed to convert religion after wedding, and their child will choose the religion for itself once it attains 21 years of age.

[18 years = passing right out of school [12th std] the child would be still ignorant of the society,
in India child doesn't develop basic knowledge of the surroundings at least until passing out of college at 21 years].

Conductivity/Resistivity = Very high / very poor seems like you are just passed out of school speaking to kids.

Carbon [Graphene] = 10 nΩm [10−9]
Silver = 16 nΩm [10−9]
Copper = 17 nΩm [10−9]
Aluminum = 26 nΩm [10−9]
Iron = 97 nΩm [10−9]
Carbon Steel = 143 nΩm [10−9]
Stainless Steel = 690 nΩm [10−9]

Drinking water = 2 to 2000
Glass = [10^11 to 10^15]

So see the difference between the Aluminum and Glass, it's in order of 10^24 difference. [Billion x Billion x Million] times !!!
_______________________________________________
As far as density,

*List of Popular Solid densities in [Kg / Liter],

Aluminum [Al] = 2.71
Copper [Cu] = 8.94
Iron [Fe] = 7.85 [Same for Stainless Steel]

Meaning,
1 Liter of Copper will weigh = ~9 Kg
1 Liter of Aluminum will weight = ~2.7 Kg

i.e, for example,
10 meter of copper wire weigh* = ~9 Kg
10 meter of Aluminum wire weight* = ~4 Kg [Thicker wire, less weight, adjusted for conductivity same as copper]

So though aluminum might get thicker wire than copper, it'll still be less in weight due to low density and cheaper $$$ / meter,
that's the reason, long distance power lines use Aluminum instead of Copper.

Conductivity of Copper wire = same = Conductivity of slightly thicker Aluminum wire

This smart bandage releases meds on command for better healing

Taking care of a cut or scrape usually means swapping out the bandage a few times, and maybe putting a little healing cream or hydrogel on there. But what if the dressing could dispense that stuff on its own? That’s the idea behind a smart bandage now being tested by engineers from the University of Nebraska-Lincoln, Harvard and MIT.

Instead of plain sterile cotton or other fibers, this dressing is made of “composite fibers with a core electrical heater covered by a layer of hydrogel containing thermoresponsive drug carriers,” which really says it all.

In a paper published in the journal Advanced Functional Materials, the team documents how in tests, critters (not humans — those tests come later) healed better when given the active bandage. They also made sure that the heat didn’t affect the healing process or the medication.

For ordinary scrapes a normal bandage (or plaster, for our friends across the pond) is probably still more than sufficient — this is for people whose healing processes are inhibited, or for whom frequent dressing changes are impossible or inconvenient.

Next up, in addition to further testing to satisfy the FDA, is investigating how to integrate sensors with the fibers, to measure blood glucose levels, pH and other indicators of how the healing process is going. Maybe soon your bandage will even include a progress bar.
