一.    Micrography

Micrography is also the art of using microscopes to make photographs. 'Micrograph' is an image obtained by

means of a microscope and contains extensive details that form the features of a microstructure. "Etching" is

done to improve contrast between phases by selective attack of some phases using reagents. Micrography is

a Metallurgist's forte.

Optical microscope and electron microscope are extensively used in micrography or metallography and are

indispensable. A wealth of information can be obtained from a simple micrograph like behavior of the material

under different conditions, the phases found in the system, failure analysis, grain size estimation, elemental

analysis and so on.

 

二.    Nikon Small World

The Nikon International Small World Competition first began in 1974 as a means to recognize and applaud the

efforts of those involved with photography through the light microscope. Since then, Small World has become

a leading showcase for photomicrographers from the widest array of scientific disciplines.

A photomicrograph is a technical document that can be of great significance to science or industry. But a good

photomicrograph is also an image whose structure, color, composition, and content is an object of beauty, open

to several levels of comprehension and appreciation.

四. 各式酒類

Rose wine (玫瑰紅酒)
The distinctive pink hue is rather a red herring in this sample as the colours in the image reflect

the different levels of absorption of the light after it has passed through the sample, not the

wine's original colour. White wine would probably look much the same at this range (Caption

analysis by Dr Ellen Friel, Science Programme Manager, Royal Society of Chemistry)
 

Whisky (威士忌)
The deep amber colour of the whisky comes from the barrels it is matured in - where much of the chemistry

of whisky takes place

Vodka(伏特加)
The globules are possibly due to the dissolved solids in the drink, sugar in this case. There are less colours as there tends to be less oily flavour components in vodka because it is distilled and run through charcoal to purify it and take these out 
 

Dry martini(馬丁尼)
the streaks could be due to higher levels of essential oils or possibly due to tannin like compounds which

give rise to its bitterness

Tequila(龍舌蘭)

Much darker probably either due to the high levels of fructose in the tequila from the agave plant or

possibly high levels of essential oils also from the agave plant
