Electrolytic cell Converts electrical energy → chemical energy Reaction is non-spontaneous Example: Electrolysis of water, metal plating 👇👇

An electrochemical cell uses a redox reaction (oxidation + reduction) to either produce electricity or use electricity to drive a chemical reaction. 🔬 Key components Two electrodes Anode: where oxidation occurs Cathode: where reduction occurs 👇👇

Water vs Hydrogen Peroxide: Detailed Chemical & Molecular Comparison Explore the key differences between water (H2O) and hydrogen peroxide (H2O2) in this instructional video. Dive into their chemical formulas, molecular structures, bond types and angles, polarity, and stability.

BREAKING NEWS The Royal Swedish Academy of Sciences has decided to award the 2025 #NobelPrize in Chemistry to Susumu Kitagawa, Richard Robson and Omar M. Yaghi “for the development of metal–organic frameworks.”

💡 Science Tip: Applying lemon juice slows browning because the vitamin C and acidity inhibit PPO’s activity. #Chemistry #ScienceInEverydayLife #Chemist #Enzymes #Research

Here’s what happens: 1️⃣ Cutting the apple damages its cells, releasing an enzyme called polyphenol oxidase (PPO). 2️⃣ PPO reacts with phenolic compounds in the fruit in the presence of oxygen. 3️⃣ This reaction produces melanin pigments, which give the apple its brown color. 👇

Why Do Apples Turn Brown After You Cut Them? This everyday phenomenon is a great example of chemistry in action. When you slice an apple, you’re not just preparing a snack—you’re triggering a chemical reaction called enzymatic browning. 👇👇

@Dr_Berionni @EuCOMC2025 @UNamur @EvaHeviaGroup Can we join it online?

The group is well represented at the @EuCOMC2025 symposium (European Conference on Organometallic Chemistry) in Bern🇨🇭. Take a look at the posters of Maxence A-27, Akshitha B-52 and Romain B-10 (@UNamur🇧🇪) today and Wednesday. @EvaHeviaGroup #EuCOMC2025 (eucomc2025.scg.ch).

@FurukawaG_Kyoto Congratulations 👏

Congratulations!! Ayana and Heng-Yu got poster prizes at #ISMSC2025, Kyoto, and #MOFSchool, Como, respectively. Excellent achievements!!

2. Instrumentation: Different light sources and detection methods. 3. Application: AAS is more versatile, while flame photometry is specific to certain elements.

3. Application: Quantitative analysis of alkali and alkaline earth metals. 4. Sensitivity: Suitable for analyzing elements like sodium, potassium, and calcium. Key Differences 1. Principle: AAS measures absorption, while flame photometry measures emission.👇

Differentiate b/w AAS & Flame Photometer AAS (Atomic Absorption Spectroscopy) 1. Principle: Measures the absorption of light by atoms in a sample. 2. Instrumentation: Uses a hollow cathode lamp, atomizer, and detector. 3. Application: Quantitative analysis of elements, 👇
