The Determination of the Mechanical, Optoelectronic, Structural and Transport Attributes of Double Perovskite AInGaBr (A=K, Rb, Cs) Halides for Renewable Energies: A DFT Study.

Safer and more environmentally friendly alternatives to lead-based perovskites include lead-free halide perovskites, which retain good optoelectronic capabilities while reducing environmental toxicity. They also align better with ecological and regulatory standards for green technologies. In this manuscript, we have presented the first principles analysis of the physical traits of AInGaBr (A=K, Rb, Cs).

Effect of Ni-Doping on the Optical, Structural, and Electrochemical Properties of Ag Nanoclusters.

Atomically precise metal nanoclusters (NCs) can be compositionally controlled at the single-atom level, but understanding structure-property correlations is required for tailoring specific optical properties. Here, the impact of Ni atom doping on the optical, structural, and electrochemical properties of atomically precise 1,3-benzene dithiol (BDT) protected Ag NCs is studied. The Ni-doped Ag (NiAg(BDT)) NCs, are synthesized using a co-reduction method and characterized using electrospray ionization mass spectrometry (ESI MS), ion mobility spectrometry (IMS), and X-ray photoelectron spectroscopy (XPS).

Synergistic Influence of FRET on a High Quantum Yield π- Conjugate Polycarbazole-ZnS Composite Thin Film.

The incorporation of semiconducting materials into the π-conjugate polymer improves the optical, thermal, electrical, and electrochemical properties of optoelectronic devices. In this study, polycarbazole-zinc sulfide (PCZ) composites are synthesized via an in situ polymerization process, and their thin films are produced by spin coating. ZnS enhances the charge transfer qualities of polycarbazoles, which in turn results in better photophysical and electrical characteristics.

Effect of the molar ratio of (Ni and Fe) on the magnetic, optical and antibacterial properties of ternary metal oxide CdO-NiO-FeO nanocomposites.

In this work, the effect of the molar ratio of (Ni and Fe) on the properties of CdO-NiO-FeO nanocomposites was investigated. The synthesis of CdO-NiO-FeO nanocomposites was carried out by self-combustion. XRD, UV-Vis, PL and VSM were used to describe the physical properties of the materials.

Synthesis of Trimetallic (Ni-Cu)@Ag Core@Shell Nanoparticles without Stabilizing Materials for Antibacterial Applications.

We report a simple method to prepare colloidal trimetallic (Ni-Cu)@Ag core@shell nanoparticles (NPs) without stabilizing materials. Experimental evidence was found for the successful synthesis of these NPs using X-ray diffraction (XRD), optical spectroscopy, and high-resolution transmission electron microscopy (HRTEM). The presence of core metals (Ni and Cu) was confirmed by elemental analysis using a total reflection X-ray fluorescence (TXRF) analysis.

High Performance of Carbon Monoxide Gas Sensor Based on a Novel PEDOT:PSS/PPA Nanocomposite.

In this work, the carbon monoxide (CO) detection property of poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate)/poly(-anisidine) (PEDOT:PSS/PPA) nanocomposite was systematically investigated at room temperature. The PEDOT:PSS/PPA nanocomposite was synthesized by the cost-effective "in situ chemical oxidation polymerization" technique. The electric, optical, spectroscopic, and structural properties of the as-prepared nanomaterials were analyzed with -, UV-vis, Raman, Fourier transform infrared (FTIR), and X-ray diffraction (XRD) spectroscopies.

Quantitative considerations about the size dependence of cellular entry and excretion of colloidal nanoparticles for different cell types.

Most studies about the interaction of nanoparticles (NPs) with cells have focused on how the physicochemical properties of NPs will influence their uptake by cells. However, much less is known about their potential excretion from cells. However, to control and manipulate the number of NPs in a cell, both cellular uptake and excretion must be studied quantitatively.

The Effect of Precursor Concentration on the Particle Size, Crystal Size, and Optical Energy Gap of CeSnO Nanofabrication.

In the present work, a thermal treatment technique is applied for the synthesis of CeSnO nanoparticles. Using this method has developed understanding of how lower and higher precursor values affect the morphology, structure, and optical properties of CeSnO nanoparticles. CeSnO nanoparticle synthesis involves a reaction between cerium and tin sources, namely, cerium nitrate hexahydrate and tin (II) chloride dihydrate, respectively, and the capping agent, polyvinylpyrrolidone (PVP).

Awareness of the Risk Factors for Heart Attack Among the General Public in Pahang, Malaysia: A Cross-Sectional Study.

Background: Cardiovascular disease is a leading nationwide cause of morbidity and mortality. Public awareness of risk factors for heart attacks is thought to impact the burden of disease, prevention, and timely management. The objective of this study was to assess the awareness of risk factors for heart attack and to identify the factors associated with the awareness of all modifiable risk factors for heart attack in the general population.

Development of questionnaire on awareness and action towards symptoms and risk factors of heart attack and stroke among a Malaysian population.

Background: The awareness of symptoms and action towards heart attack and stroke is important to reduce the morbidity and mortality in both developed and developing countries. The aim of this study was to develop a questionnaire on awareness and action towards symptoms and risk factors of heart attack and stroke among lay public in Malaysia. The questionnaire was developed in both English and Bahasa Melayu.
