How are all of you? hope you all are well. Today, I'm going to discuss the international internship program abroad for undergraduate students (1st year to 4th year). Specifically, I will talk about the internship program in Japan. Most of the student does not know about this program. generally, they think the study abroad only for Masters, Ph.D., and Post-doc. but they don't know it’s possible to pursue a fully-funded internship and a research program as well. Do you know Japanese universities offer lots of internship positions for undergraduate students all over the world? So let's get started- . There are lots of international internship programs in Japan. But I will focus a few prestigious internship programs. . Q. Why will you participate in the internship program? Well. There is a lot of reason. Here only a few given below. . Developing skills (Leadership skill, teamwork) Gathering new knowledge Global experience and network Important for future research. Making CV str...

Do you know that your mouth is the site of some very cool chemistry? And that it’s home to the hardest substance in your body? Let’s know something. The crown of a mature tooth is composed of two unique layers. The outermost layer is the enamel. It is the hardest and most highly mineralized substance in the human body. It is even harder than bone. But it is tissue and not a bone. This tissue has high mineral content which makes it the hardest substance. Enamel is mainly made up of approximately 96% crystalline form of calcium phosphate known as Hydroxyapatite ( Ca₁₀(PO₄)₆(OH)₂)  and the other 4% is water & organic material particularly enamel-specific proteins called enamelins. That crystalline calcium phosphate is not pure crystal, because this inorganic material substituted with carbonate ions( CO 3^ 2- ) and contain trace minerals such as strontium, magnesium, lead & fluoride. The second layer underlying the rigid enamel is tougher mineralized protein-rich tissue known a...

 Do you ever think that an egg is not floating in the water but a rotten egg is floating!! How impressive! It's all about density.  When the density is high, then it sinks but when the density is running low, it floats. Well, let's take a clear concept about this.   When we enter an egg into the water, it sinks. Because the density of the water molecule is smaller than the density of an egg. But,  when the egg has begun to rotten.  It produces Hydrogen Sulfide(H2S) gas. Melting Point : -82*C   Molar Mass : 34.08 gm/mol-1 The mean density of the rotten egg is smaller than the density of the water molecule, because of producing H2S gas.  Then H2S gas will create an upright pressure which is called one type of buoyancy. Thus the density of a rotten egg has become smaller than the water molecule and it floats. But, if you mix some salt ( NaCl) into the water, then the density of the water molecule will become raise. After that, a normal egg can be fl...

The color of your blood is red... No doubt.  But the blood in your veins is bluish. Isn't it a strange thing?  let's talk about this.  Blood is the fluid that our hearts pump through our circulatory systems to reach oxygen and other materials to all the cells in our body. The average amount of blood in a human body is 4.5 liter and the fluid is made up of clearish liquid plasma.  There are three types of blood cells such as red, white, and platelets, and they are floating into it. R.B.C bears Oxygen W.B.C fights against the antigen. Platelets help to clot blood,  RBC has hemoglobin which is an iron-rich protein that binds to oxygen (HbO2) and gives our blood a red hue. Hemoglobin is a kind of Hemochrome, a protein that is the red coloring matter of the blood.  Not all animals use hemoglobin, so that's why not all animals' blood is red. That indicates that, our blood color depends on what we are, and how our blood moves oxygen around our body.  For exam...

           There is a speech, that is if you eat Pineapple and milk together, you will die.💀 Many people told us that not to eat milk and pineapple together. Now let's know about this , is it a rumor?  or a true speech. Well, pineapple contains Vitamin A , Vitamin C , Ascorbic Acid ( C₆H₈O₆) , Calcium (Ca) , Pottasium (K) and Citric Acid ( C₆H₈O₇) (8%), , Pantothenic Acid ( C 9 H 17 NO 5 )(Vitamine B.)  and Milk is a perfect food. but there is a speech we always listen that, if you eat Pineapple and milk together, you will die because of sepsis .  It is a complete food taboo . We know that pineapple contains some acid and also we know that if we add some acid in milk then the milk will be converted into curdle...  when we eat them together, the same thing happens in our stomach. It may contains indigestion , colic or diarrhoea. If anyone have a problem Of Gastric, they have to avoid this.  In Dessert and Custard items or pine...

• Over 1500 flavour components have been identified in chocolate, making it one of the most complex chemical mixtures known. • Chemicals in chocolate can affect your brain, potentially making you feel happier and more alert. 𝑾𝒉𝒂𝒕 𝒂𝒄𝒕𝒖𝒂𝒍𝒍𝒚 𝒊𝒔 𝒄𝒉𝒐𝒄𝒐𝒍𝒂𝒕𝒆? A confectionery product characterised by the presence of cocoa bean derivatives,’ namely cocoa liquor, cocoa butter and cocoa solids. 𝑪𝒉𝒐𝒄𝒐𝒍𝒂𝒕𝒆 𝒂𝒔 𝒂 𝑷𝒊𝒄𝒌-𝑴𝒆-𝑼𝒑 Theobromine [𝐭𝐡𝐞 𝐜𝐡𝐞𝐦𝐢𝐜𝐚𝐥 𝐟𝐨𝐫𝐦𝐮𝐥𝐚 𝐂𝟕𝐇𝟖𝐍𝟒𝐎𝟐] is an alkaloid, a family of compounds that many plants produce, including the cacao plant. Chocolate is the richest natural source of theobromine, but coffee and tea contain some of it too. Theobromine chemically resembles caffeine and has a similar stimulating effect on our brains. The combination of theobromine and caffeine found in chocolate is believed to create the small lift we feel after eating it. Shadman Khan  Hajee Mohammad Danesh Science & Technology ...
