Atomically thin TiO nanosheets synthesized using liquid metal chemistry.

The library of true two-dimensional materials is limited since many transition metal compounds are not stratified and can thus not be easily isolated as nanosheets. Here, micron-sized ultrathin rutile TiO2 nanosheets featuring uniform thickness (2 ± 0.5 nm) with dielectric constant (ε⊥ = 24) have been synthesized via a liquid metal synthesis strategy.

Congenital Brucellosis: A Systematic Review of the Literature.

Background: Knowledge of the spectrum of presentations and the outcome of congenital brucellosis should expedite diagnosis and improve prognostication.

Methods: A systematic review of literature of cases of congenital brucellosis was performed on October 10, 2017 (registered as PROSPERO CRD42017072061).

Results: A case seen by the authors was added to the review, yielding 44 reported cases of which 22 (50%) were from Turkey, Saudi Arabia, or Kuwait.

Consequences of brucellosis infection during pregnancy: A systematic review of the literature.

Background: The aim was to establish the incidence of adverse outcomes with brucellosis infection during pregnancy.

Methods: Ovid Medline (1946-), Ovid Embase (1974-), and Web of Science (Clarivate Analytics) (1900-), the World Health Organization website and Google were searched September 27, 2017 for (i) outcomes with brucellosis diagnosed during pregnancy and (ii) studies with retrospective diagnosis of maternal brucellosis following adverse pregnancy outcomes.

Results: Sixty studies met inclusion criteria.

Exfoliation Solvent Dependent Plasmon Resonances in Two-Dimensional Sub-Stoichiometric Molybdenum Oxide Nanoflakes.

Few-layer two-dimensional (2D) molybdenum oxide nanoflakes are exfoliated using a grinding assisted liquid phase sonication exfoliation method. The sonication process is carried out in five different mixtures of water with both aprotic and protic solvents. We found that surface energy and solubility of mixtures play important roles in changing the thickness, lateral dimension, and synthetic yield of the nanoflakes.

Optical gas sensing properties of nanoporous Nb2O5 films.

Nanoporous Nb2O5 has been previously demonstrated to be a viable electrochromic material with strong intercalation characteristics. Despite showing such promising properties, its potential for optical gas sensing applications, which involves the production of ionic species such as H(+), has yet to be explored. Nanoporous Nb2O5 can accommodate a large amount of H(+) ions in a process that results in an energy bandgap change of the material which induces an optical response.

Plasmon resonances of highly doped two-dimensional MoS₂.

The exhibition of plasmon resonances in two-dimensional (2D) semiconductor compounds is desirable for many applications. Here, by electrochemically intercalating lithium into 2D molybdenum disulfide (MoS2) nanoflakes, plasmon resonances in the visible and near UV wavelength ranges are achieved. These plasmon resonances are controlled by the high doping level of the nanoflakes after the intercalation, producing two distinct resonance peak areas based on the crystal arrangements.

Substoichiometric two-dimensional molybdenum oxide flakes: a plasmonic gas sensing platform.

Two-dimensional (2D) molybdenum oxides at their various stoichiometries are promising candidates for generating plasmon resonances in visible light range. Herein, we demonstrate plasmonic 2D molybdenum oxide flakes for gas sensing applications, in which hydrogen (H2) is selected as a model gas. The 2D molybdenum oxide flakes are obtained using a grinding-assisted liquid exfoliation method and exposed to simulated sunlight to acquire its substoichiometric quasi-metallic form.

Field effect biosensing platform based on 2D α-MoO(3).

Electrical-based biosensing platforms offer ease of fabrication and simple sensing solutions. Recently, two-dimensional (2D) semiconductors have been proven to be excellent for the fabrication of field effect transistors (FETs) due to their large transconductance, which can be efficiently used for developing sensitive bioplatforms. We present a 2D molybdenum trioxide (MoO3) FET based biosensing platform, using bovine serum albumin as a model protein.
