Hvordan er det nu lige med cement og beton? Det finder vi ud af i dette afsnit om cement. Rygterne går på, at det er det materiale menneskeheden bruger anden mest af (dvs. efter vand), så det er ekstremt vigtigt i byggebranchen. Men når man bruger så meget af noget, kan det også have negative konsekvenser - i dette tilfælde i form af CO2 udledning. Vi dykker ned i kemien og finder ud af, hvor CO2’en i fremstillingen kommer fra. Magnus læser op af Bjerrums (Jep ham med diagrammet) beskrivelse ...

Bu bölümde, Alice Harikalar Diyarının en dikkat çekici karakterlerinden biri olan Çılgın Şapkacının ardındaki kimyayı, civa(II) nitrat gerçeğini anlattım.

La betametasona, un glucocorticoide sintético de alta potencia, representa una herramienta terapéutica fundamental en el manejo de dermatosis inflamatorias como eccemas, psoriasis y dermatitis alérgicas. Sin embargo, su uso prolongado o inadecuado se asocia con un riesgo significativo de proliferación fúngica secundaria, particularmente en contextos de inmunosupresión local y alteración de la barrera cutánea. Este fenómeno surge de la interacción compleja entre las propiedades antiinflamatorias del

Melissa and Jam delve into the intricate phenomenon of static electricity. They discuss their own experiences with static shocks and static cling, particularly in the winter months. They explain the concept of contact electrification and the tribal electric effect, providing basic explanations along with why these do not fully account for everything we observe. They highlight recent scientific research, revealing that much about static electricity remains a mystery, including why it occurs more in

Questa fonte unica di New Scientist discute lo sviluppo di una nuova plastica biodegradabile prodotta dal bambù, una risorsa altamente rinnovabile. La plastica, creata dai ricercatori della Shenyang University of Chemical Technology, è resistente e durevole quanto le plastiche convenzionali, rendendola adatta per applicazioni come gli interni delle automobili e gli elettrodomestici. Il materiale si ottiene trattando la cellulosa del bambù con cloruro di zinco e acido, e i suoi creatori sostengono

In this episode of No Filter with Kobo, Gabby dives into the colorful world of eye makeup, from lashes to lids and brows. She’s joined by Maria Alvarez, Chemist from Kobo’s European Applications Lab, who breaks down the key ingredients and formulation strategies that bring eye products to life. From long-wear performance powered by film formers to the volumizing magic of silica and fibers, this episode shares insights into how chemists balance innovation, texture, and wearability across mascaras,

🎙️ Episode: My Go-To Periodic Table Unit -Activities, Trends, and Timing TipsA practical walkthrough of my Periodic Table unit—history hooks, must-teach trends, hands-on labs, and lots of low-prep practice to cement understanding. Episode Description In this episode, I run through exactly how I teach the Periodic Table in Chem I and Honors: how I hook students with music and history, scaffold core periodic trends (atomic radius, ionization energy, electronegativity, ionic radius), and

Por que os manguezais são chamados de “fábricas de carbono azul”? Neste episódio especial da Semana Nacional de Ciência e Tecnologia 2025, o Papo de Química entra no mangue para entender como esses ecossistemas costuram clima, biodiversidade e vida humana. Recebemos Prof. Dr. Clemente Coelho Júnior (UPE/Instituto BiomaBrasil) e Prof. Dr. Fábio Pedrosa (UPE/UNICAP/LIMCS – Climate Labs) para uma conversa direta sobre:Carbono azul, o que é, como se mede e por que o mangue guarda tantoQualidade da água:

Three hundred thousand American deaths in three years…and the chemistry is still evolving. If the cartels turned the lab into the battlefield, why haven’t we brought our own defenses?In this investigation, host Michael Brown sits down with Collin Gage, CEO and co-founder of ARMR Sciences, to unpack a controversial but potentially game-changing idea: an immunotherapy “vaccine” designed to block fentanyl from reaching the brain. Gage explains the planned Phase I/II human trial, why military and first

Il podcast estratto da "Composizione Chimica e Sapore del Kopi Luwak" discute la base chimica che potrebbe spiegare il sapore superiore attribuito al caffè Kopi Luwak, noto anche come caffè di zibetto. Questo caffè è prodotto dopo che le bacche vengono mangiate e digerite dallo zibetto delle palme asiatico, un processo che presumibilmente fermenta e modifica i chicchi. Lo studio ha confrontato i chicchi di caffè Robusta raccolti manualmente e quelli derivati dallo zibetto, rilevando che il caffè di

In this episode, we dive deep into the complex and often misunderstood world of endocrine disruption with toxicologist, pharmacologist and endocrine disruption researcher, Chris Borgert PhD. We unpack how the science has evolved, what we actually know about real-world risks, and how public fear has outpaced scientific consensus. From moral panics around masculinity and fertility to the rise of science sensationalism and skewed research incentives, this conversation explores how a nuanced scientific

Often in crime shows and movies, we usually skip to the result of forensic testing. But have you ever wondered how investigators get those results? On this exciting episode of Let’s Talk Chemistry edited by Presley Vu, hosts Amber Bakkum and Mehreen discuss our interview with Dr. Bruce McCord, Analytical and Forensic Chemistry Professor at Florida International University and deputy editor for the journal ELECTROPHORESIS. Dr. McCord talks all about his work on drug analysis, explosive detection, and

Il podcast discute una scoperta significativa riguardante l'acqua confinata in canali su scala nanometrica, dimostrando che le sue proprietà elettriche sono drasticamente alterate rispetto all'acqua sfusa. In particolare, la ricerca condotta da scienziati dell'Università di Manchester, tra cui Laura Fumagalli e Andre Geim, ha rivelato un aumento della conduttività elettrica fino a 100.000 volte lungo il canale quando l'acqua è fortemente confinata. Si ipotizza che questo fenomeno sia dovuto a
