UNLABELLED This work presents a CH3NH3PbI3/PCBM organic solar cell. Organic PCBM film and CH3NH3PbI3 perovskite film are deposited on the PEDOT PSS/ITO glass substrate by the spin coating method. The performance of the organic solar cells was observed by changing the thickness of CH3NH3PbI3 perovskite. The thickness of a perovskite film can affect the carrier diffusion length in a device that...

We present the results of temperature-dependent self-assembly of dicarbonitrile-pentaphenyl molecules (NC-Ph5-CN) on Cu(111). Our low-temperature scanning tunneling microscopy study reveals the formation of metal-organic and purely organic structures, depending on the substrate temperature during deposition (160-300 K), which determines the availability of Cu adatoms at the surface. We use tip ...

In this highlight we briefly review several of our recent theoretical studies focused on how the interplay between the chemical and the van der Waals interactions determines the bonding mechanism of several chemically functionalized π-conjugated organic molecules on non-magnetic and magnetic surfaces. In particular, we focus on the issue how to tailor the strength of the interaction between suc...

This paper presents flexible electronics with a bio-compatible material interface for bio-signal monitoring applications. Organic thin-film transistors (TFT) are integrated with the bio-compatible gel interface in a 1.2-μm-thick film substrate. An electrocardiogram (ECG) of a rat is amplified by an organic TFT amplifier circuit that is mounted directly on the surface of the heart. In addition t...

The energy-level alignment at interfaces between three electroactive conjugated organic materials and Au was systematically varied by adjusting the precoverage of the metal substrate with the electron acceptor tetrafluoro-tetracyanoquinodimethane (F4-TCNQ). Photoelectron spectroscopy revealed that electron transfer from Au to adsorbed F4-TCNQ was responsible for lowering the hole-injection barr...

Single-crystal field effect transistors of the organic semiconductor dithiophene-tetrathiafulvalene (DT-TTF) were prepared by drop casting. Long, thin crystals connected two microfabricated gold electrodes, and a silicon substrate was used as a back gate. The highest hole mobility observed was 1.4 cm2/Vs, which is the highest reported for an organic semiconductor not based on pentacene. A high ...

the biodesulfurization (bds) of sulfur compounds in fossil fuels is a process to reduce sulfur dioxide emissions that cause environmental pollution. gordonia alkanivorans ripi90a is able to convert dibenzothiophene, an organic sulfur compound in petroleum, to 2-hydroxybiphenyl (2-hbp) in 4s pathway. in this study, (dbt), dsza and dszb, dbt sulfone monooxygenase, and desulfinase were respectivel...

A two-dimensional nanoporous covalent organic framework can be prepared on a Au(111) substrate with near complete surface coverage and can be used to control the organisation of a sublimed layer of C(60).

Papain activity was studied in water-organic solvent mixtures using the fluorogenic substrate Dabcyl-Lys-Phe-Gly-Gly-Ala-Ala-Edans. The increase of organic solvent (MeOH, EtOH, iPrOH, TFE, MeCN, (MeO)2Et and DMF) concentration in the mixture caused a substantial decrease the initial rate of papain-catalyzed hydrolysis. Moreover, the number of papain active sites decreased with the increase of D...
