Sinteza, spektroskopska karakterizacija i ab initio istraživanje tioanaloga spirohidantoina [PDF]

, 2005
Dithioanalogues of cycloalkanespiro-5-hydantoins were prepared by reaction of the respective spirohydantoins with Lawesson’s reagent or P4S10. Cycloalkanespiro-5-(2-thiohydantoins) and cycloalkanespiro-5-(4-hydantoins) were also synthesized from ...

Recent advances in solid-state organic lasers

, 2011
Organic solid-state lasers are reviewed, with a special emphasis on works published during the last decade. Referring originally to dyes in solid-state polymeric matrices, organic lasers also include the rich family of organic semiconductors, paced by ...

Hydrogel‐Based Smart Materials for Wound Healing and Sensing

Aggregate, EarlyView.
The graphical abstract illustrates the role of hydrogel‐based flexible materials in advancing biomedical applications, including wound healing, point‐of‐care diagnostics, smart patches, and wearable devices. Hydrogels are particularly promising in modern wound care due to their high‐water content, flexibility, and biocompatibility.

What is... a G_2 manifold? [PDF]

Notices of the American Mathematical Society 58, 580-581 (2011), 2011
This is a very short and elementary introduction to G_2 manifolds. We stress the similarities and the differences with K\"ahler manifolds in general and with Calabi-Yau manifolds in particular.

Investigating nano-structured domains within ionic liquids: the effect of cation change on thermal equilibrium and relaxation of spiropyran and spirooxazine. [PDF]

, 2009
The established belief that ionic liquids (ILs) behave as homogenous solvents such as that observed in molecular solvents has been challenged.1, 2 Previous use of solvatochromic probe dyes has allowed for the traditional parameter of ‘polarity’ to be ...

A Novel Merocyanine Derivative for Probing Polarity at Cubosome Interfaces

Asian Journal of Organic Chemistry, EarlyView.
This study develops a synthetic route to C10SP, a polarity‐sensitive sensor embedded in phytantriol‐based cubosomes. Strategic steps included tertiary amine‐mediated amidation to covalently attach a hydrophobic tail and controlled nitrogen methylation to form the iminium moiety within the indolenine scaffold.

Limits of isotropic universes with interacting fluids [PDF]

arXiv, 2013
We find various asymptotic limits of universes containing two interacting fluids which interact and exchange energy. We study the finite-time singularities that may develop in these cosmologies and obtain the asymptotic behaviours of the solutions near such blow up regimes.

Synthesis of Benzodithieno[5.5.5.6]Fenestranes: Unexpected Epimerization and Regiochemical Outcomes

Asian Journal of Organic Chemistry, EarlyView.
Isomeric [5.5.5.6]fenestranes annulated with one benzene and two thiophene rings are accessible via di‐2‐ and di‐3‐thienylspirane intermediates. The key double cyclization step involves surprising stereoselectivity and regioselectivity. In particular, cis‐di(2‐thienyl)spirane precursors lead to the all‐cis‐fenestrane skeleton by an unexpected acid ...
