Caffeine crystals. Coloured scanning electron micrograph (SEM) of anhydrous caffeine crystals (1,3,7-trimethylxanthine). They were produced by a process called sublimation. A liquid containing caffine, such as coffee, is frozen and heated to 238 degrees Celsius, causing the frozen liquid to vaporise without going through the liquid phase. The vapour is then condensed, which drives the water out and results in anhydrous crystals. Some of the crystals have symmetrically intergrown (upper centre, red and yellow). Caffine stimulates the central nervous system (CNS), increasing alertness and deferring fatigue. It occurs in coffee beans and tea leaves. Magnification: x400 at 10 centimetres high.

👮🏽‍♂️ GENERAL ARMS (muon): In love with Guila's charms, he tries, like many other Atomland boys, to win her over, but Guila's heart doesn't open to romance easily, some call her "impossible". General “Brazos” is not one to give up easily, he has his eyes set on Guila and only on her. The great General Arms achieved his position at an early age due to his ethical, disciplined and humble character. Atomland did not have armed forces but due to the arrival of invasions and attacks, the Kings formed a local army, led by General Arms, James Arms, whose main mission is to protect and serve his people.

False-colour scanning electron micrograph of a TM 2716 integrated circuit, showing a corner of the device with surrounding connecting pin leads. This chip is of the EPROM type - Eraseable, Programmable, Read Only Memory. EPROM chips are programmed by applying a voltage across selected connecting pins. Some such devices may then be subsequently reprogrammed - other types, PROMs, may not. Magnification: X 30 at 6x4. 5cm size. The TM 2716 EPROM chip is of the NMOS type (n- type

Everything is made of the same stuff, of atoms.. So this design is about everything? :-)

Have fun testing the people you meet, to see if they can guess the CPU! (Also available with white text.)

Think Like A Proton Always Positive - Funny Atom Science Teacher Tee

A design to remind you to be positive.

Physics turns me on. Literally. The heating of the light bulb filament excites the atoms, causing the electrons to jump to a higher energy level, releasing their extra energy in the form of a light photon. Are you turned on yet?

Perfect for your Mondays! I'm positive about that. :)

Carbon nanotechnology. Computer model of buckminsterfullerene (C60) balls in a carbon nanotube. The coloured peaks show electron waves. The nanotube is a cylinder of carbon atoms less than a billionth of the width of a human hair. Buckminsterfullerenes (buckyballs) are spherical groups of 60 carbon atoms. A nanotube stuffed with buckyballs (a peapod) is a goodconductor of heat and electricity. Altering the number of buckyballs in the tube alters the conductive properties of the nanotube. Peapods could be used to build electrical components on a molecular scale.

Diatoms. Coloured scanning electron micrographs (SEMs) of a circular arrangement of various diatoms. Diatoms are planktonic unicellular algae. They have a mineralised cell wall (frustule) divided into two halves. The frustule contains silica and provides protection and support. Magnification unknown.

Protons Have Mass? I Didn't Even Know They were Catholic

The orbitals are swirling in Storistir to make holiday ornaments! Antimony, element 51, is derived from the Greek stibi, meaning mark since it was used for blackening eyebrows and eyelashes. Other uses of antimony include hardening bullets, creating flame-retardant materials, and strengthening the lead in storage batteries. Antimony is about ten times more toxic than lead and is also a cumulative poison.

Be positive (;

The orbitals are swirling in Storistir to make holiday ornaments! 100 FM sounds like it should be a radio station, but element 100, Fm, was named after Enrico Fermi, who created the world's first nuclear reactor at an underground squash court in Chicago.

It's an ion, a cation to be exact. A funny science geeky joke about an ion. A chemistry pun that people who like science, chemistry, physics, or biochemistry will understand.

The Universe revolves around me! A funny joke to buy for someone or even to buy for yourself!
