Hubertina D. Hogan

Hubertina D. Hogan is a chemistry topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Hubertina D. Hogan rather than just read about it. In short: Hubertina Dorothy Clayton Hogan (December 25, 1924 – April 14, 2017) was an American textile chemist, employed for most of her career in the United States Army's Combat Capabilities Development Command laboratories in Natick, Massachusetts. Early life and education Hubertina "Tina" Clayton was from Trenton, New Jersey, the daughter of Joseph Aloysius Clayton and Elsie Papendick Clayton (later Dietrich).

Hubertina D. Hogan belongs to chemistry; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Hubertina D. Hogan to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Hubertina D. Hogan from memory before moving on to harder problems.

Reference excerpt

Hubertina Dorothy Clayton Hogan (December 25, 1924 – April 14, 2017) was an American textile chemist, employed for most of her career in the United States Army's Combat Capabilities Development Command laboratories in Natick, Massachusetts.

Early life and education Hubertina "Tina" Clayton was from Trenton, New Jersey, the daughter of Joseph Aloysius Clayton and Elsie Papendick Clayton (later Dietrich). Her father was a World War I veteran. She was named for her paternal grandmother, Hubertina Brandt Clayton, who lived with her family. She graduated from Trenton Cathedral High School in Trenton in 1943, and from Seton Hill University in 1947. She pursued further studies in biochemistry at the University of Pennsylvania in Philadelphia, and in textile chemistry at Lowell Technological Institute. Her master's thesis was titled "The relationship between hydrogen ion concentration and a water-oil repellent fluorochemical finish" (1973).

Career From 1952 into the 1970s, Hogan was a research chemist at the Army's Clothing, Equipment, and Materials Engineering Laboratory in Natick, Massachusetts. Her research involved textiles and their properties of repelling or absorbing environmental hazards in combat settings. She "developed the analytical method for determining chrome content of feathers and down." She was a member of the American Leather Chemists Association beginning in 1955.

Publications Professional publications by Hogan included articles in Textile Research Journal, Journal of the American Leather Chemists Association, and Analytical Chemistry.

"A Rapid Sole Leather Tannage with Aldehydes" (1958, with Ludwig Seligsberger and C.W. Mann) "The Actions of Acrylonitrile and Acrylamide upon Collagen" (1958, with L. Seligsberger) "Observations on the Tanning Action of Synthetic Polyphenols" (1963, with L. Seligsberger) "Determination of bis (2-chloroethyl) sulfide in a Dawson apparatus by gas chromatography" (1972, with R. L. Erickson, R. N. MacNair and R. H. Brown) Feasibility Study to Determine the Fluorine Content in Quarpel-treated Fabrics by Analysis with a 14 MeV Neutron Activation Source (1972, with Forest C. Burns and Gil M. Dias) "Sorptive Textile Systems Containing Activated Carbon Fibers" (1974, with Gilbert N. Arons, Richard N. MacNair, and Laurance G. Coffin)

Personal life Clayton married John Daniel Hogan in 1967, in Massachusetts; her husband died in 1973. She lived with her mother in Jobstown, New Jersey in the 1980s. She died in Cumming, Georgia, in 2017, aged 92 years.

Worked examples

Example 1 — a first encounter with Hubertina D. Hogan

Start with the simplest possible case. Write down what Hubertina D. Hogan claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Hubertina D. Hogan before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Hubertina D. Hogan ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Hubertina D. Hogan

In research: Hubertina D. Hogan appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Hubertina D. Hogan in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Hubertina D. Hogan is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1924 births, 2017 deaths, American women scientists, so understanding it makes those chapters shorter.
In everyday life: Look for Hubertina D. Hogan outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
