Substituted thiourea incorporated rhodamine-based chemosensors for selective detection of aluminium ions.

Various metal ions' contemporary utility, biological essence and environmental impact have stimulated their selective and sensitive detection, particularly when present in traces. In this context, methodological explorations relying on structural and functional modulations of prime components and interactive parameters have been pivotal in developing chemosensors for selective detection of such metal ionic inputs. In this investigation, three thiourea-incorporated rhodamine B derivatives varying in their substituent modified covalent architectures were synthesized, and their photophysical signalling responses were monitored in the presence of different metal ions.

Unravelling molecular interaction of the uranyl(VI) complex with bovine serum albumin.

Interest in the biotoxicology of uranium resulting from its inherent radioactive as well as chemical properties has been growing intensely in recent years. Indeed, uranium in its stable form as UO species is ubiquitously found on earth, and this form is commonly known as the uranyl(VI) ion. The unusual electronic environment at the core of the uranyl(VI) complex plays an important role in its interaction with biomacromolecules.

Mixing twist-bend and ferroelectric nematic liquid crystals.

Twist-bend (N_{tb}) and ferroelectric (N_{F}) nematic liquid crystals exhibit several novel effects and new physical properties. Here, we report experimental studies on the phase diagram and some physical properties of binary mixtures of CB9CB and RM734 mesogens. Both N-N_{tb} and N-N_{F} phase transition temperatures and the corresponding enthalpies decrease significantly and, eventually, these transitions disappear at some intermediate compositions, stabilizing wide nematic phase (N).

"It was the first time someone had died before my eyes…": A qualitative study on the first death experiences of nursing students.

Background: Accompanying a person at their death is a common experience in nurse education. In addition to all death experiences that are a meaningful part of the nursing profession, the first death experience is very important. However, there is limited understanding of nursing students' first death experiences.

Probing the interaction of uranyl(VI) complex with bovine serum albumin via in-depth experimental and computational perspectives.

Interaction aspects of uranyl(VI) complexes as well as the coordinated ONNO-donor ligand with bovine serum albumin (BSA) were investigated by the fluorescence spectroscopy and computational insights. Under optimal physiological condition, it was observed that there was significant decrease in fluorescence intensity of BSA upon interaction with uranyl(VI) complexes as well as the ligand. The mechanism of interaction between the uranyl(VI) complex and BSA protein was examined by fluorescence measurement.
