Current advances in nanodrug delivery systems for malaria prevention and treatment
DISCOVER NANO - Tập 18 - Trang 1-31 - 2023
Malaria is a life-threatening, blood-borne disease with over two hundred million
cases throughout the world and is more prevalent in Sub-Saharan Africa than
anywhere else in the world. Over the years, several treatment agents have been
developed for malaria; however, most of these active pharmaceutical ingredients
exhibit poor aqueous solubility and low bioavailability and may result in
drug-resis...
Nano-indentation study of dislocation evolution in GaN-based laser diodes
DISCOVER NANO -
AbstractThe slip systems and motion behavior of dislocations induced by
nano-indentation technique in GaN-based LDs were investigated. Dislocations with
burgers vector of b = 1/3 <11$$\overline{2}$$ 2 ¯ 3> were introduced on either
{11$$\overline{2}$$ 2 ¯ 2} <11$$\overline{2}$$ 2 ¯ 3>, or {1$$\overline{1}$$ 1 ¯
01} <11$$\overline{2}$$ 2 ¯ 3> pyramidal slip systems in the upper p-GaN layer.

Transition metal-based nanoparticles as potential antimicrobial agents: recent advancements, mechanistic, challenges, and future prospects
DISCOVER NANO - Tập 18 - Trang 1-20 - 2023
Bacterial transmission is considered one of the potential risks for communicable
diseases, requiring promising antibiotics. Traditional drugs possess a limited
spectrum of effectiveness, and their frequent administration reduces
effectiveness and develops resistivity. In such a situation, we are left with
the option of developing novel antibiotics with higher efficiency. In this
regard, nanopartic...
Enhancing subthreshold slope and ON-current in a simple iTFET with overlapping gate on source-contact, drain Schottky contact, and intrinsic SiGe-pocket
DISCOVER NANO - Tập 18 - Trang 1-13 - 2023
In this paper, we present a new novel simple iTFET with overlapping gate on
source-contact (SGO), Drain Schottky Contact, and intrinsic SiGe pocket
(Pocket-SGO iTFET). The aim is to achieve steep subthreshold swing (S.S) and
high ION current. By optimizing the gate and source-contact overlap, the
tunneling efficiency is significantly enhanced, while the ambipolar effect is
suppressed. Additionally...
Zn‐doped MnOx nanowires displaying plentiful crystalline defects and tunable small cross-sections for an optimized volcano-type performance towards supercapacitors
DISCOVER NANO - Tập 18 - Trang 1-16 - 2023
MnOx-based nanomaterials are promising large-scale electrochemical energy
storage devices due to their high specific capacity, low toxicity, and low cost.
However, their slow diffusion kinetics is still challenging, restricting
practical applications. Here, a one-pot and straightforward method was reported
to produce Zn-doped MnOx nanowires with abundant defects and tunable small
cross-sections, e...
Preparation, characterization, and magnetic resonance imaging of Fe nanowires
DISCOVER NANO - Tập 18 Số 1
AbstractA facile template method was employed to synthesize Fe nanowires of
different sizes, dimensions. Comprehensive analyses were conducted to explore
their morphology, structure, composition, and magnetic properties. The surface
of as-prepared Fe nanowires was modified with SiO2 by sol–gel method to improve
the dispersion of as-prepared Fe nanowires in aqueous solution. Furthermore, the
relaxa...
Core atoms escape from the shell: reverse segregation of Pb–Al core–shell nanoclusters via nanoscale melting
DISCOVER NANO - Tập 18 Số 1
AbstractMelting is a phase transition that profoundly affects the fabrication
and diverse applications of metal nanoclusters. Core–shell clusters offer
distinctive properties and thus opportunities compared with other classes of
nano-alloys. Molecular dynamics simulations have been employed to investigate
the melting behaviour of Pb–Al core–shell clusters containing a fixed Pb147 core
and varying ...
Assessment of the cytotoxic effect of carboxymethyl chitosan-loaded amygdalin nanoparticles against human normal and cancer cell lines
DISCOVER NANO - - 2024
In recent years, the development of antitumor drugs has been dedicated to
natural products. Amygdalin is a natural herbal cyanoglycoside that has
anticarcinogenic effect on many types of cancers once hydrogen cyanide (HCN) is
released. The main objective of the present study is to synthesize and
investigate the potential of carboxymethyl chitosan nanoparticles (CMC NPs) as
drug delivery agents for...
ROS-generating nanoplatforms as selective and tunable therapeutic weapons against cancer
DISCOVER NANO - Tập 18 Số 1
AbstractReactive species refers to a group of chemicals, mainly reactive oxygen
species (ROS) and reactive nitrogen species (RNS), that are naturally formed by
cells as a byproduct of cell metabolism and regulated by various internal and
external factors. Due to their highly chemical reactivity, ROS play a crucial
role in physiological and pathological processes which is why studies on ROS
regulat...
Electronic structure of superconducting VN(111) films
DISCOVER NANO - Tập 19 Số 1
AbstractVanadium nitride (VN) is a transition-metal nitride with remarkable
properties that have prompted extensive experimental and theoretical
investigations in recent years. However, there is a current paucity of
experimental research investigating the temperature-dependent electronic
structure of single-crystalline VN. In this study, high-quality VN(111) films
were successfully synthesized on ...
