Semiconductor crystals smaller than about 10 nm, known as quantum dots, have properties that differ from large samples, including a band gap that becomes larger for smaller particles. These properties create several applications for quantum dots. In this paper new shapes of quantum dot arrays are used to enhance the photo physical properties of gold nano-particles. This paper presents a study o...

Abstract This article provides a brief review of conjugated polymers and the various typical polymerization reactions exploited by community to synthesise different polyelectrolytes with varied backbone systems. We further discuss detailed emphasises mechanism involved such as photo-induced electron transfer, resonance energy intra-molecular charge transfer in detection or sensing analytes. Owi...

We report here a study of light-matter strong coupling involving three molecules with very different photo-physical properties. In particular we analyze their emission properties and show that the excitation spectra are very different from the static absorption of the coupled systems. Furthermore we report the emission quantum yields and excited state lifetimes, which are self-consistent. The a...

SMS messaging technology allows for short messages to be exchanged between individuals at a relatively low cost. Current SMS messaging technology is limited to person-to-person messaging; many other forms of social communication also allow for person-to-location messaging. This is particularly important for domestic messaging since messages may need to be broadcast to an entire family or househ...

In recent decades, there have been many advances in digital media and technologies that have disrupted professions traditionally rooted in physical and print media as their core competency. Often, digital transformations of such professions not only change the way these professionals collectively define themselves, but also dramatically alter the physical work environment in which they have for...

The control of photo physical processes with judiciously tailored intense femtosecond laser pulses is a cutting edge topic in modern laser science and might pave the way to optically controlled organic chemistry. In this contribution we report on pulse-shaping experiments using closed-loop, optimal control feedback for selective bond breaking in amino acid complexes, such as Ac-Phe-NHMe. This m...

By employing a tridentate thiophosphoramide ligand, [(NHAQ)3P[double bond, length as m-dash]S] (AQ = 3-quinolinyl), a cationic MOF, {[Cu6I5(L(1))2](OH)·3DMF·2.5MeOH}n, was synthesized. Photo-physical studies on the 2D-MOF showed an unusual thermochromic behaviour emitting a blue fluorescence at 298 K due to the AQ chromophore and an orange-yellow phosphorescence at 77 K due to the [Cu6I5](+) unit.

We recently reported on the physical characteristics of photo-triggerable liposomes containing dipalmitoylphosphatidylcholine (DPPC), and 1,2-bis (tricosa-10,12-diynoyl)-sn-glycero-3-phosphocholine (DC(8,9)PC) carrying a photo agent as their payload. When exposed to a low-intensity 514 nm wavelength (continuous-wave) laser light, these liposomes were observed to release entrapped calcein green ...

This paper presents an efficient hardware-accelerated method for novel view synthesis from a set of images or videos. Our method is based on the photo hull representation, which is the maximal photo-consistent shape. We avoid the explicit reconstruction of photo hulls by adopting a view-dependent plane-sweeping strategy. From the target viewpoint slicing planes are rendered with reference views...
