Analytical Chemistry
Analytical chemistry studies and uses instruments and methods to separate, identify, and quantify matter. In practice, separation, identification or quantification may constitute the entire analysis or be combined with another method. Separation isolates analytes. Qualitative analysis identifies analytes, while quantitative analysis determines the numerical amount or concentration. Analytical chemistry consists of classical, wet chemical methods and modern, instrumental methods. Classical qualitative methods use separations such as precipitation, extraction, and distillation. Identification may be based on differences in color, odor, melting point, boiling point, solubility, radioactivity or reactivity. Classical quantitative analysis uses mass or volume changes to quantify amount. Instrumental methods may be used to separate samples using chromatography, electrophoresis or field flow fractionation. Then qualitative and quantitative analysis can be performed, often with t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anion
An ion () is an atom or molecule with a net electrical charge. The charge of an electron is considered to be negative by convention and this charge is equal and opposite to the charge of a proton, which is considered to be positive by convention. The net charge of an ion is not zero because its total number of electrons is unequal to its total number of protons. A cation is a positively charged ion with fewer electrons than protons while an anion is a negatively charged ion with more electrons than protons. Opposite electric charges are pulled towards one another by electrostatic force, so cations and anions attract each other and readily form ionic compounds. Ions consisting of only a single atom are termed atomic or monatomic ions, while two or more atoms form molecular ions or polyatomic ions. In the case of physical ionization in a fluid (gas or liquid), "ion pairs" are created by spontaneous molecule collisions, where each generated pair consists of a free electron and ...

Second World War
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polish Resistance Movement In World War II
The Polish resistance movement in World War II (''Polski ruch oporu w czasie II wojny światowej''), with the Polish Home Army at its forefront, was the largest underground resistance movement in all of occupied Europe, covering both German and Soviet zones of occupation. The Polish resistance is most notable for disrupting German supply lines to the Eastern Front (damaging or destroying 1/8 of all rail transports), providing intelligence reports to the British intelligence agencies (providing 43% of all reports from occupied Europe), and for saving more Jewish lives in the Holocaust than any other Western Allied organization or government. It was a part of the Polish Underground State. Organizations The largest of all Polish resistance organizations was the Armia Krajowa (Home Army, AK), loyal to the Polish government in exile in London. The ''AK'' was formed in 1942 from the Union of Armed Struggle (''Związek Walki Zbrojnej'' or ZWZ, itself created in 1939) and would eve ...

V-2 Rocket
The V-2 (german: Vergeltungswaffe 2, lit=Retaliation Weapon 2), with the technical name ''Aggregat 4'' (A-4), was the world’s first long-range guided ballistic missile. The missile, powered by a liquid-propellant rocket engine, was developed during the Second World War in Nazi Germany as a "vengeance weapon" and assigned to attack Allied cities as retaliation for the Allied bombings of German cities. The rocket also became the first artificial object to travel into space by crossing the Kármán line (edge of space) with the vertical launch of MW 18014 on 20 June 1944. Research into military use of long-range rockets began when the graduate studies of Wernher von Braun attracted the attention of the Wehrmacht. A series of prototypes culminated in the A-4, which went to war as the . Beginning in September 1944, over 3,000 were launched by the Wehrmacht against Allied targets, first London and later Antwerp and Liège. According to a 2011 BBC documentary, the attacks from r ...

Operation Most III
Operation Most III (Polish for ''Bridge III'') or Operation Wildhorn III (in British documents) was a World War II operation in which Poland's '' Armia Krajowa'' provided the Allies with crucial intelligence on the German V-2 rocket. Background From November 1943 onwards, the Intelligence Division of the Polish Home Army (''Armia Krajowa'') obtained parts of the V-2 rocket, which was being tested at a missile launch site near Blizna, central Poland. The availability of parts increased from April 1944, when numerous test rockets fell near Sarnaki village, in the vicinity of the Bug River, south of Siemiatycze. On the night of 20 May 1944 a particularly intact rocket fell into the swampy banks of the Bug. Parts of the rocket were secured by the Armia Krajowa, and analyzed at its secret laboratories in Warsaw. The analysis was performed by Professor Janusz Groszkowski (radio and guidance), Marceli Struszyński (fuel), Bogdan Stefanowski (engine), Antoni Kocjan, and others. ...

Wacław Struszyński
Wacław Struszyński (; 1904–1980) was a Polish electronics engineer who made a vital contribution to the defeat of U-boats in the Battle of the Atlantic. He designed an exceptional radio antenna which enabled effective high frequency (HF) radio direction finding systems to be installed on Royal Navy convoy escort ships. Such direction finding systems were referred to as HF/DF or Huff-Duff, and enabled the bearings of U-boats to be determined when the U-boats made high frequency radio transmissions. Early life Struszynski was born in Wieruszów near Łódź (now in Poland) in 1904. He spent his youth in Moscow, but the family returned to Poland in 1918. He received his master's degree in Engineering (''Dipl. Ing.'') at the Warsaw University of Technology in 1929, and joined the Polish State Telecommunication Establishment, where he became head of the Direction Finding Division. When Poland was invaded in 1939, he was evacuated from Warsaw, and reached England in 1940. Str ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1880 Births
Year 188 (CLXXXVIII) was a leap year starting on Monday of the Julian calendar. At the time, it was known in the Roman Empire as the Year of the Consulship of Fuscianus and Silanus (or, less frequently, year 941 ''Ab urbe condita''). The denomination 188 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
