Molecular Modelling and Computer Simulation Group - MolMod-CS

Cientistas do Instituto de Química (IQ) da Unicamp exploram o potencial das chamadas tecnologias facilitadoras na síntese de moléculas orgânicas. Essas inovações proporcionam maior controle, eficiência, segurança e sustentabilidade difíceis de atingir por vias convencionais, como o chamado “processo em batelada”.

Liderada pelo professor Julio Cezar Pastre, a equipe aposta em técnicas como o fluxo contínuo e a mecanoquímica. Ao trocar reatores tradicionais por microrreatores com luz de LED e moinhos de impacto sem solventes, por exemplo, o grupo reduziu o tempo de reações de cinco horas para até 15 minutos, com alta seletividade.

Os avanços desempenham um importante papel para a indústria farmacêutica, setor em que os solventes geram 80% dos resíduos. Alinhada à química verde, a estratégia viabiliza matérias-primas para medicamentos a partir de biomassas renováveis, reduzindo danos ambientais e a dependência de insumos fósseis.

The first compound to block a key copper transport system, MKV3, made MRSA significantly more susceptible to copper and increased copper-driven cell death in cultured cancer cells. How far this early-stage approach can go still needs more testing.

New way to harness copper makes antibiotic-resistant bacteria and cancer cells more vulnerable University of Missouri researchers have discovered a new way to harness one of the body's natural defenses: copper. While copper is essential for life and helps power important biological processes, having too much of it can be toxic. To keep copper levels in balance, cells rely on specialized prote...

Ring-shaped degradable polymers matched PLA’s oxygen-blocking performance while proving substantially tougher and more ductile. The materials are not yet ready for packaging, and film processing and recycling tests still need to come next.

Rearranged polymer chains create degradable materials with potential for stronger, tougher packaging What if the key to making stronger, more sustainable plastics isn't changing their ingredients, but rearranging their molecules? Virginia Tech researchers have put that idea to the test, creating degradable polymers with a new molecular architecture that combines properties often difficult to achiev...

A common blue pigment converted CO₂ directly into methane in one electrochemical step, reaching 79.5% methane efficiency and staying above 60% selectivity for about 80 hours. Why it favors methane over other products is not fully settled, though calculations suggest a lower-energy pathway.

Inexpensive blue pigment enables efficient one-step conversion of carbon dioxide to methane
