WebI’m an adaptive, creative and innovative individual with a knack for identifying and solving problems. I am very passionate about tech, business & art. Strong analytical and problem-solving skills, organized, ambitious, friendly, and proactive with a team-oriented mentality. I am always excited to tackle new challenges and exceed expectations in any position I hold. WebCryptophane cages can adopt either an anti or syn configuration that present different recognition properties. While the synthesis of anti-cryptophanes is well reported, the synthesis of syn-cryptophanes remains a challenge.Herein, we demonstrate that the use of HFIP as a co-solvent during the second ring closure reaction significantly affects the …
WebIn this study we analyse from a theoretical perspective the encapsulation of both gaseous H2 and CO2 at different conditions of pressure and temperature in a Type II porous liquid, composed by nanometric scale cryptophane-111 molecules dispersed in dichloromethane, using atomistic molecular dynamics. Gaseous H2 tends to occupy cryptophane–111’s … WebCryptophane sensors designed for proteins, metal ions, nucleic acids, pH, and temperature have achieved nanomolar-to-femtomolar limits of detection via a combination of 129 Xe …
