I am in the Uk and recently bought some budget zinc chloride AAA cells.  
I was surprised they has a no-load voltage of 1.65v.  A different brand
has a voltage of 1.69v.
Isn't that rather high?  How can the manufacturers cram such a high

Hi alI
I know that alkalides ans also electrides have
been synthesized with the aid of cryptands.
I'm not aware of hydrides of the same type.

I need to start a new book that begins to have Scientists not as
minion slaves under some obtuse

How can you keep a fat, like butter, from "freezing" at room
temperature?

When I mix white vitamin C powder and white Niacinimide powder in
water it turns yellow. From the little chemistry I've taken, color
change is an indication of a reaction. What is the mixture turning
into?

There is a lot of discussion of positive effects of curcumin
once it lands in human body. But somehow I could not find any info about
what for is it used inside its original host, turmeric.
   Such a powerful and rather complex molecule must be used for

In the context of ab initio quantum chemistry, one often finds the
terms ''chemical accuracy'' and ''spectroscopic accuracy''.
Which actual accuracy do these labels convey?

As a part of our project we need to get the relation between
sweat sugar and blood sugar.Is there any direct relation between these
two.?Is there any change in sweat sugar content for a normal person
and a diabetic person.

Sun's low magnetic activity may portend an ice age
The Canadian Space Agency's radio telescope has been reporting Flux
Density Values so low they will mean a mini ice age if they continue.
Like the number of sunspots, the Flux Density Values reflect the Sun's

Can anyone recommend a source for anhydrous acetone (<0.1% water
content)? The most "anhydrous" Sigma sells contains 0.2% water. My lab
does not have the infrastructure for drying acetone myself with NaI
and distillation.
