Dual release with a bit of logic!

We show the release of a double cargo payload with 2 stimuli, force and water, with an AND gate mechanism.

📈 Junio de 2025, el mes más anómalamente cálido en España desde que hay registros.

→ Con una desviación en su temperatura media de 3.6 °C respecto a lo normal, supera a octubre de 2022, cuya desviación fue de 3.4 °C.

→ Fue también un mes seco.

La ola de calor pulveriza el record histórico de España en junio con 46 grados en El Granado (Huelva) La Aemet prevé que las temperaturas extremas se prolonguen hasta el martes y sigan siendo elevadas el resto de la semana

España nunca había registrado los 46 grados en el mes de junio desde que hay series históricas de las temperaturas en el país. Hasta este sábado, cuando los termómetros marcaron en El Granado (Huelva) un dato sin precedentes a estas alturas del año

Scientists use bacteria to turn plastic waste into paracetamol Genetically modified E coli used to create painkillers from material produced from plastic bottles

Prof. Stephen Wallace: “What this technology shows is that by merging chemistry and biology in this way for the first time, we can make paracetamol more sustainably and clean up plastic waste from the environment at the same time.” www.theguardian.com/science/2025...

We take advantage of the mechanical equilibration to explore the details of the mechanical motion which, in the presence of chemical energy input can drive the formation of a non-equilibrium steady state - see SI and very recent paper:

Winery cuts costs with carbon capture pilot plant that uses metal–organic framework Carbon dioxide captured from fermentation in a scalable, selective and sustainable manner

The famous Familia Torres winery has set up a pilot plant using new MOFs to capture carbon dioxide for use as a protective pocket of inert gas inside tanks to avoid oxidation.

Research centres weather unprecedented blackout in Spain and Portugal Backup batteries and diesel generators guaranteed the stability and security of scientific systems

Blackouts in Spain and Portugal stopped trains, traffic, and telecommunications – but research resisted! 💪🏼 My latest for @chemistryworld.com covers the remarkable response of Iberian research centres to survive several hours without electricity: www.chemistryworld.com/news/researc... #chemsky 🧪

Bueno, si con esto de apagarla y encenderla no arreglamos del todo España, yo ya no sé qué hacer.

Take two polls to help Iupac define molecular machines An Iupac committee wants your input to guide its recommendations for key terms in the field

The 2016 Nobel prize in chemistry was awarded 'for the design and synthesis of molecular machines'. Ironically, we do not know exactly what constitutes a molecular machine. With the ultimate goal of unifying definitions and standardising terminology, Iupac needs your help!

Scaling-up may not be the most fun part of the job, BUT if you want your #nanomaterials to be useful, you need to make plenty, and make it cheap. Here are two tales of scaling-up production of #nanomaterials. Read on, it's a short 🧵!

How to make the perfect boiled egg—if you have the patience New method cracks the code for a soft yolk and a cooked white

The perfect approach to boiling an egg, researchers found, was cooking it in 100°C water for 2 minutes, then 30°C water for 2 minutes, and repeating for a total of 32 minutes.

Is @tomasnicolas.bsky.social's paper the first post of @cp-chem.bsky.social? Yes, yes, I think it is!

Non-scientist translation: You know that whole "every action makes an equal and opposite reaction" rule? It works with molecules! But they were able to prove it with some cool moving molecules that go up and down but always balance. Knowing how molecules work helps us with medication and tech!
