Attosecond bunches of gamma photons and positrons generated in nanorod array targets

open access: yes, 2018
The sub-atomic experimental exploration of physical processes on extremely short time scales has become possible by the generation of high quality electron bunches and x-ray pulses with sub-femtosecond durations.

Linear free vibration of micro-/nano-plates with cut-out in thermal environment via modified couple stress theory and Ritz method

open access: yesAin Shams Engineering Journal, 2018
This article aims to study the natural frequency of defective micro-/nano-plates because not only the existence of cut-outs in plates may be essential on the basis of their desired functionality but also the resonant frequency can be changed by cut-outs.

Enhancement of the Modulation Response of Quantum-Dot-Based Down-Converted Light through Surface Plasmon Coupling

open access: yesMolecules, 2022
In this paper, we first elaborate on the effects of surface plasmon (SP) coupling on the modulation responses of the emission of a light-emitting diode (LED) and its down-converted lights through colloidal quantum dots (QDs).

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

open access: yesMolecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

MECHANISM OF SILICA NANO-PLATE FORMATION FROM LUCENTITE

open access: yesSurface Review and Letters, 2007
The mechanism of formation of silica nano-plates by exfoliation of a phyllosilicate magnesium containing clay, Lucentite, in an aqueous solution of poly(acrylic acid) has been studied. Fourier transform infrared spectroscopy and Mg K -edge near edge X-ray adsorption fine structure (NEXAFS) analysis shows that non-surface (bulk) Mg ions were not ...

Electrical Behaviour of Glass/ Carbon- Phenolic Conductive Hybrid Composite Woven Used In Electrostatics Precipitator Filter

open access: yesInternational Journal of Electrochemical Science, 2014
Electrical behavior of hybrid conductive composites made of phenolic resin, graphite woven, glass woven and graphite nano powder has been studied for the first time in the present research to apply as collecting plates in electro static precipitators. To

Learning from Nature: Bioinspired Strategies Towards Antimicrobial Nanostructured Systems [PDF]

open access: yes, 2018
Microbial contamination still remains a major issue of the modern era, due to the widespread of drug-resistant pathogens. This has prompted researchers to come up with novel antimicrobial systems that could overcome antibiotic-resistance. In this context,

Identification of serum protein biomarkers for pre‐cancerous lesions associated with pancreatic ductal adenocarcinoma

open access: yesMolecular Oncology, EarlyView.
This work identified serum proteins associated with pancreatic epithelial neoplasms (PanINs) and early‐stage PDAC. Proteomics screens assessed genetically engineered mice with abundant PanINs, KPC mice (Lox‐STOP‐Lox‐KrasG12D/+ Lox‐STOP‐Lox‐Trp53R172H/+ Pdx1‐Cre) before PDAC development and also early‐stage PDAC patients (n = 31), compared to benign ...

Crystal Growth and Characterization of Bulk Sb2Te3Topological Insulator

open access: yes, 2018
The Sb2Te3 crystals are grown using the conventional self flux method via solid state reaction route, by melting constituent elements (Sb and Te) at high temperature (850 C), followed by slow cooling (2 C per hour).The weak anti localization (WAL ...
