High-performance dual-mode ultra-thin broadband CdS/CIGS heterojunction photodetector on steel.

An ultra-thin CdS/CIGS heterojunction photodiode fabricated on steel firstly exhibits dual-mode broadband photodetection from ultraviolet to near infrared spectrum. In the photovoltaic mode, the CIGS photodiode, working as a self-driven photodetector, shows an outstanding photodetection capability (under a light power density of 20 µW cm at 680 nm), reaching a record detectivity of ∼4.4×10 Jones, a low noise equivalent power (NEP) of 0.

High-responsivity broadband photodetection of an ultra-thin InS/CIGS heterojunction on steel.

${\rm{Cu}}({\rm{In}},{\rm{Ga}}){\rm{S}}{{\rm{e}}_2}$ (CIGS) is a promising light harvesting material for large-area broadband photodetection, but it has been rarely studied up to now. Here an InS/CIGS heterojunction photodiode on steel is shown to be highly broadband photo-sensitive, with a photoresponsivity over 0.8 A/W, an external quantum efficiency over 100%, and a detectivity over 8×10 Jones from 505 to 910nm under a reverse bias of 1 V.

Human mind has microwave electromagnetic nature and can be recorded and processed.

Introduction: In 2014 and 2015 Professor of neurology Andrey Bryukhovetskiy published a novel theory of the information-commutation organization of the human brain in Russia, China and the USA. The theory posits the hypothesis that the higher nervous activity (cognitive, intellectual, mnestic) of the humans and their mind are material and have microwave electromagnetic nature. The theory perceives the human mind as a result of dynamic extracortical information-commutation relations of the super-positions of the electromagnetic waves of ultra high frequency emitted by different areas of the human brain in the inter-membrane cerebrospinal fluid space of the human head at a certain period of time.

Formation of gigahertz pulse train by chirped terahertz pulses interference.

The state-of-art broadband THz sources can contribute to the development of short-range 6G communications. This paper has demonstrated the feasibility of forming the controllable sequence of THz subpulses in the temporal domain and the corresponding quasidiscrete spectrum by the interference of two THz pulses with an exponential chirp. Moreover, due to small time delay between these pulses the temporal and spectral structures are similar to each other (so-called "linkage relation").

Non-aqueous solution-processed phosphorene by controlled low-potential electrochemical exfoliation and thin film preparation.

Black phosphorus (BP) in its monolayer form called phosphorene is thought of as a successor of graphene and is of great interest for (opto)electronic applications. A quantitative and scalable method for the synthesis of (mono-)few-layer phosphorene has been an outstanding challenge due to the process irreproducibility and environmental degradation capability of the BP. Here, we report a facile controlled electrochemical exfoliation method for the preparation of a few-layer phosphorene (FP) with nearly 100% yield.

2D WS liquid crystals: tunable functionality enabling diverse applications.

The first observation of liquid crystalline dispersions of liquid phase-exfoliated tungsten disulfide flakes is reported in a range of organic solvents. The liquid crystals demonstrate significant birefringence as observed in the linear and circular dichroism measurements respectively. In particular, linear dichroism is observed throughout the visible range while broad-band circular dichroism can be observed in the range from 500-800 nm.

Transmission Properties of FeCl-Intercalated Graphene and WS Thin Films for Terahertz Time-Domain Spectroscopy Applications.

Time-resolved terahertz spectroscopy has become a common method both for fundamental and applied studies focused on improving the quality of human life. However, the issue of finding materials applicable in these systems is still relevant. One of the appropriate solution is 2D materials.

High Kerr nonlinearity of water in THz spectral range.

The values of the nonlinear refractive index coefficient for various materials in the terahertz frequency range exceed the ones in both visible and NIR ranges by several orders of magnitude. This allows to create nonlinear switches, modulators, systems requiring lower control energies in the terahertz frequency range. We report the direct measurement of the nonlinear refractive index coefficient of liquid water by using the Z-scan method with broadband pulsed THz beam.

Preparation of Zirconium-89 Solutions for Radiopharmaceutical Purposes: Interrelation Between Formulation, Radiochemical Purity, Stability and Biodistribution.

Zirconium-89 is a promising radionuclide for nuclear medicine. The aim of the present work was to find a suitable method for obtaining zirconium-89 solutions for radiopharmaceutical purposes. For this purpose, the ion exchange behavior of zirconium-89 solutions was studied.

Combination of cyclophosphamide and double-stranded DNA demonstrates synergistic toxicity against established xenografts.

Background: Extracellular double-stranded DNA participates in various processes in an organism. Here we report the suppressive effects of fragmented human double-stranded DNA along or in combination with cyclophosphamide on solid and ascites grafts of mouse Krebs-2 tumor cells and DNA preparation on human breast adenocarcinoma cell line MCF-7.

Methods: Apoptosis and necrosis were assayed by electrophoretic analysis (DNA nucleosomal fragmentation) and by measurements of LDH levels in ascitic fluid, respectively.

To the novel paradigm of proteome-based cell therapy of tumors: through comparative proteome mapping of tumor stem cells and tissue-specific stem cells of humans.

We performed proteome mapping (PM), cataloging, and bioinformation analysis of protein lysates of human neural (CD133(+)) progenitor and stem cells (NPSCs) isolated from the olfactory sheath of a nose, multipotent mesenchymal (CD29(+), CD44(+), CD73(+), CD90(+), CD34(-)) stromal cells (MMSCs) isolated from human bone marrow, and tumor (CD133(+)) stem cells (TSCs) isolated from the human U87 glioblastoma (GB) cell line. We identified 1,664 proteins in the examined lysates of stem cells (SCs), 1,052 (63.2%) of which are identical in NPSCs and TSCs and 607 proteins (36.
