👨🏻‍🔬👩🏻‍🔬Giving our students access to open-source tools like @Prusa3D is essential for building skills they will use throughout their professional careers. This semester, Gael proposed using 3D printing for his final solar energy project at @BUAPoficial

@emollick Smaller language models are well-suited for running locally, particularly for tasks like checking grammar and improving the readability. In contrast, frontier models excel at exploring new ideas and pushing forward the current boundaries of research. We should choose wisely.

It is one reason why I think the push for smaller, local models is more complicated than people think. If you want good answers, especially good answers to unexpected problems, frontier models will generally outperform smaller models on a wide range of tasks.

One of the most important properties of LLMs that we take for granted is that newer, bigger models are just better at everything. The AI Labs are pouring effort into economically valuable fields like coding, but bigger models are also better at negotiation, alignment, poetry, etc

👨🏻‍🔬While completing his professional residency. Jorge is developing novel semiconductor materials at the Photovoltaic Innovation Lab (LIFYC). 🔬 👩🏻‍🔬From TEC de Zacatepec to @ierunam , the future of energy starts here. #semiconductor #thinfilm #solarcells

A great advisor doesn't just supervise, they get involved! 🌱⚡ Dr. Nair demonstrates this by personally guiding students in developing semiconductors for solar cells. Innovation in progress at the Semiconductors Coating Pilot Plant! 🔬🇲🇽 @ierunam

👩🏻‍🔬👨🏻‍🔬 This Wednesday, April 29, we had the pleasure of welcoming Materials Science students from the Faculty of Engineering (CIME), @BUAPoficial. They toured our lab and experienced the full research cycle of antimony chalcogenide thin-film solar cells. #BUAP #Semiconductors

🏃‍♂️Follow your dreams …

👩‍🔬👨‍🔬The use of open-source software ensures reproducibility, transparency, and equitable access in scientific research, promoting a more collaborative and verifiable science. #thinfilm #solarcells

👩‍🔬👨‍🔬 Honored to host Dr. Jordi Aguiló Llobet, Emeritus Professor from Universidad Autónoma de Barcelona at @BUAPoficial 🔬 At Lab101, we presented solar cells developed via chemical processes. The photos show in-situ I-V curve measurements for these cells. #thinfilm #BUAP

🛠️ Open source software gave a second life to my MacBook Air 2015, and today I went one step further: I replaced the battery myself 🔋 Repair your machines and fight against planned obsolescence.

🚀 Open-source tools = open science. Let’s build research that belongs to everyone! Dr. Jesús Capistrán #python #LLMs #semiconductor

☕️ In my office, semiconductor research runs on caffeine as much as it runs on electron #thinfilm #semiconductors

🚀 Impressive tech in action! At @ierunam, Yareli Colin demonstrated LYFICS' thin-film photovoltaic modules. These homegrown devices from IER-UNAM (led by Dr. Nair and his research teams) are already powering multi-colored LEDs. 💡🔋 #WomenInSTEM #Semiconductors

🌍 Honoring the legacy of Nair Group (Karunakaran & Santhamma) and his impact on the scientific community. His work on chemical bath deposition has revolutionized the field, paving the way for new applications in photovoltaics, solar drying, solar radiation filters🌞 @ierunam

👩‍🔬👨‍🔬Today, I had the incredible opportunity to share my research at the 2nd National Congress on #Semiconductor Materials and Devices at @BUAPoficial ! Want to know how to make them yourself? Read the full scientific article here: 👉 doi.org/10.1016/j.jall…
