Este documento describe los principios básicos y tipos de cromatografía. Explica que la cromatografía es un proceso de separación de los componentes de una mezcla a través de la interacción diferencial de las sustancias con fases móviles y estacionarias. Describe los tipos principales como cromatografía en columna, capa fina e intercambio iónico, y sus aplicaciones en el análisis de colorantes y compuestos orgánicos.

Product Design Trends in 2024 | Teenage EngineeringsPixeldarts
The realm of product design is a constantly changing environment where technology and style intersect. Every year introduces fresh challenges and exciting trends that mold the future of this captivating art form. In this piece, we delve into the significant trends set to influence the look and functionality of product design in the year 2024.
How Race, Age and Gender Shape Attitudes Towards Mental HealthThinkNow
Mental health has been in the news quite a bit lately. Dozens of U.S. states are currently suing Meta for contributing to the youth mental health crisis by inserting addictive features into their products, while the U.S. Surgeon General is touring the nation to bring awareness to the growing epidemic of loneliness and isolation. The country has endured periods of low national morale, such as in the 1970s when high inflation and the energy crisis worsened public sentiment following the Vietnam War. The current mood, however, feels different. Gallup recently reported that national mental health is at an all-time low, with few bright spots to lift spirits.
To better understand how Americans are feeling and their attitudes towards mental health in general, ThinkNow conducted a nationally representative quantitative survey of 1,500 respondents and found some interesting differences among ethnic, age and gender groups.
Technology
For example, 52% agree that technology and social media have a negative impact on mental health, but when broken out by race, 61% of Whites felt technology had a negative effect, and only 48% of Hispanics thought it did.
While technology has helped us keep in touch with friends and family in faraway places, it appears to have degraded our ability to connect in person. Staying connected online is a double-edged sword since the same news feed that brings us pictures of the grandkids and fluffy kittens also feeds us news about the wars in Israel and Ukraine, the dysfunction in Washington, the latest mass shooting and the climate crisis.
Hispanics may have a built-in defense against the isolation technology breeds, owing to their large, multigenerational households, strong social support systems, and tendency to use social media to stay connected with relatives abroad.
Age and Gender
When asked how individuals rate their mental health, men rate it higher than women by 11 percentage points, and Baby Boomers rank it highest at 83%, saying it’s good or excellent vs. 57% of Gen Z saying the same.
Gen Z spends the most amount of time on social media, so the notion that social media negatively affects mental health appears to be correlated. Unfortunately, Gen Z is also the generation that’s least comfortable discussing mental health concerns with healthcare professionals. Only 40% of them state they’re comfortable discussing their issues with a professional compared to 60% of Millennials and 65% of Boomers.
Race Affects Attitudes
As seen in previous research conducted by ThinkNow, Asian Americans lag other groups when it comes to awareness of mental health issues. Twenty-four percent of Asian Americans believe that having a mental health issue is a sign of weakness compared to the 16% average for all groups. Asians are also considerably less likely to be aware of mental health services in their communities (42% vs. 55%) and most likely to seek out information on social media (51% vs. 35%).

5 Public speaking tips from TED - Visualized summarySpeakerHub
From their humble beginnings in 1984, TED has grown into the world’s most powerful amplifier for speakers and thought-leaders to share their ideas. They have over 2,400 filmed talks (not including the 30,000+ TEDx videos) freely available online, and have hosted over 17,500 events around the world.
With over one billion views in a year, it’s no wonder that so many speakers are looking to TED for ideas on how to share their message more effectively.
The article “5 Public-Speaking Tips TED Gives Its Speakers”, by Carmine Gallo for Forbes, gives speakers five practical ways to connect with their audience, and effectively share their ideas on stage.
Whether you are gearing up to get on a TED stage yourself, or just want to master the skills that so many of their speakers possess, these tips and quotes from Chris Anderson, the TED Talks Curator, will encourage you to make the most impactful impression on your audience.

ChatGPT and the Future of Work - Clark Boyd Clark Boyd
Everyone is in agreement that ChatGPT (and other generative AI tools) will shape the future of work. Yet there is little consensus on exactly how, when, and to what extent this technology will change our world.
Businesses that extract maximum value from ChatGPT will use it as a collaborative tool for everything from brainstorming to technical maintenance.
For individuals, now is the time to pinpoint the skills the future professional will need to thrive in the AI age.
Check out this presentation to understand what ChatGPT is, how it will shape the future of work, and how you can prepare to take advantage.
A brief introduction to DataScience with explaining of the concepts, algorithms, machine learning, supervised and unsupervised learning, clustering, statistics, data preprocessing, real-world applications etc.
It's part of a Data Science Corner Campaign where I will be discussing the fundamentals of DataScience, AIML, Statistics etc.

3. CONCEPTOS GENERALES
Fase móvil: consiste en un fluido (gas, líquido o
fluido supercrítico).
Fase estacionaria: se trata de un sólido o un
líquido fijado en un sólido.
Los componentes de la mezcla interaccionan en
forma diferente con la fase estacionaria y con la
fase móvil.
Los componentes atraviesan la fase estacionaria a
distintas velocidades y se van separando.

4. TIPOS DE CROMATOGRAFÍA
Cromatografía plana: La fase estacionaria se sitúa sobre
una placa plana o sobre un papel. Las principales técnicas
son:
Cromatografía en papel y Cromatografía en capa fina
Cromatografía en columna: La fase estacionaria se sitúa
dentro de una columna. Según el fluido empleado como fase
móvil se distinguen:
Cromatografía de líquidos.
Cromatografía de gases.
Cromatografía de fluidos supercríticos.

QUÍMICA ANALÍTICA CONTEMPORANEA. J.F. Rubinson, K.A. Rubinson,2000, Pearson Education.
5. CROMATOGRAFÍA DE COLUMNA
Consiste en la aplicación de una muestra compleja a una
columna de cristal.
Contiene una matriz sólida porosa que está inmersa en
el solvente.
Se bombea una gran cantidad de solvente a través de la
columna.
Las diferentes mezclas se van retrasando de manera
distinta según sus interacciones con la matriz.
Se pueden separar de acuerdo a su carga, su
hidrofobicidad, su tamaño o su capacidad de unirse a
grupos químicos particulares.

QUÍMICA ANALÍTICA CONTEMPORANEA. J.F. Rubinson, K.A. Rubinson,2000, Pearson Education.
7. CROMATOGRAFÍA
INTERCAMBIO IÓNICO
Se realiza sobre matrices que tienen una carga neta.
Carga negativa: intercambio de cationes
Carga positiva: intercambio de aniones
La carga de la matriz de la columna así como la carga de la
muestra dependerá del pH del solvente y de su fuerza
iónica
Se usa en la separación de moléculas grandes (proteínas y
ácidos nucleicos).

8. CROMATOGRAFÍA
INTERCAMBIO IÓNICO
Funcionamiento
En unas condiciones determinadas serán retenidas en la
columna las muestras que tengan una carga
complementaria a la de la matriz de la gel, siendo
eluidas las restantes.
Para eluir las muestras retenidas se puede variar la
carga iónica del solvente o su pH de forma que se
alcance el punto isoeléctrico de la muestra de interés
o el de la matriz, neutralizando de este modo la fuerza
que retiene a la muestra en la columna.

11. CROMATOGRAFÍA DE
EXCLUSIÓN
La cromatografía de exclusión molecular o de filtración
en gel, separa las muestras en base a su tamaño.
La matriz de la columna esta formada por un polímero
entrecruzado con poros de tamaños determinados.
Las muestras de mayor tamaño migran a lo largo de la
columna con mayor velocidad que las de tamaño
pequeño.
Las muestras de menor tamaño, entran en los poros y se
mueven a lo largo de la columna lentamente porque
tienen que atravesar los laberintos que se encuentran en
el interior de las bolas de polímero en su marcha a lo
largo de la columna
