Most parts of present computer systems are made of volatile devices, and the power to supply them to avoid information loss causes huge energy losses. We can eliminate this meaningless energy loss by utilizing the non-volatile function of advanced spin-transfer torque magnetoresistive random-access memory (STT-MRAM) t…
Organic thin film transistors have been a popular research topic in recent decades and have found applications from flexible displays to disposable sensors. In this review, we present an overview of some notable articles reporting sensing applications for organic transistors with a focus on the most recent publication…
Surface plasmon resonance imaging (SPRi) is one of the powerful tools for immunoassays with advantages of label-free, real-time, and high-throughput; however, it often suffers from limited sensitivity. Herein we report a dual signal amplification strategy utilizing polydopamine (PDA) functionalization of reduced graph…
Among the very few efforts for preparation of stable mesoporous metal–organic frameworks (MOFs), there is no report of an additive-free example via a surfactant-assisted templating method. On the other hand, photocatalytic aerobic oxidation of alcohols mediated by crystalline TiO 2 has been known as a green route, whi…
We report the development of a stress-responsive colorimetric film that can memorize the stress it has experienced. The system is designed by taking advantage of the plasmonic shift associated with the disassembly of one-dimensional gold nanoparticle chains driven by the plastic deformation of the surrounding polymer…
For the blend film of PBDTTT-C-T:PC71 BM, the use of 1,8-diiodooctane as the solvent additive enriches the polymer at the top surface, so that a power conversion efficiency of 9.13% is recorded in the inverted polymer solar cell based on the blend, which is much higher than that of the device with conventional structu…
Surfaces of commercially available membrane filters were modified by the dispersion of poly( N -vinylcarbazole) (PVK), graphene (G), poly( N -vinylcarbazole)-graphene (PVK-G), graphene oxide (GO), and poly( N -vinylcarbazole)-graphene oxide (PVK-GO) in order to impart antibacterial properties. The successful coatings…
Abstract. The reactive partitioning of cis and trans β-IEPOX was investigated on hydrated inorganic seed particles, without the addition of acids. No organic aerosol (OA) formation was observed on dry ammonium sulfate (AS); however, prompt and efficient OA growth was observed for the cis and trans β-IEPOX on AS seeds…
Ancillary ligands in heteroleptic iridium complexes significantly influence the orientation of the transition dipole moments. Ir(ppy)3, a homoleptic iridium complex, exhibits isotropic dipole orientation, whereas the heteroleptic Ir complexes of Ir(ppy)2tmd show a highly preferred dipole orientation (78%) in the horiz…
Solution processable semiconducting polymers with excellent film forming capacity and mechanical flexibility are considered among the most progressive alternatives to conventional inorganic semiconductors. However, the random packing of polymer chains and the disorder of the polymer matrix typically result in low char…

TiO2/graphene composites have been well studied as a solar light photocatalysts and electrode materials for lithium-ion batteries (LIBs). Recent reports have shown that ultralight 3D-graphene aerogels (GAs) can better adsorb organic pollutants and can provide multidimensional electron transport pathways, implying a si…
Glass fibers reinforced polymer composites have been prepared by various manufacturing technology and are widely used for various applications. Initially, ancient Egyptians made containers by glass fibers drawn from heat softened glass. Continues glass fibers were first manufactured in the 1930s for high-temperature e…
This review provides a summary statement of recommended implementations of arterial spin labeling (ASL) for clinical applications. It is a consensus of the ISMRM Perfusion Study Group and the European ASL in Dementia consortium, both of whom met to reach this consensus in October 2012 in Amsterdam. Although ASL contin…
Abstract The magnetization behavior in the Ni2Mn1.36In0.64 Heusler compound has been investigated using the 3‐6 states Potts Hamiltonian with real unit cell and magnetic exchange couplings calculated from first principles. The random quenched exchange couplings between magnetic atoms located at different coordination…
During a reorganization of the mineralogical collection of Turin University, old samples of the so-called mohsite of Colomba were found. “Mohsite” was discredited in 1979 by Kelly et al., as a result of some analyses performed on the equivalent material coming from the French region of Hautes-Alpes, but the original s…
Although calcium carbonate has been proved to be effective in neutralizing the acid degradation products of poly(l‐lactic acid) (PLLA), it has no osteoinductivity. In this study, casein phosphopeptides (CPPs)‐containing CaCO3 vaterite were synthesized by fast precipitation in an aqueous solution of CaCl2, Na2CO3, and…
A new uncommon epilithic diatom, Eunotia relicta sp. nov., is described from a small oligotrophic, acidic stream in the Chapada Diamantina region, northeast Brazil. Eunotia relicta is a typical eunotioid form with a pronounced arch on the dorsal side of the valve mainly in smaller valves. Contrary to most Eunotia spec…
A superabsorbent resin (SAR) synthesized from carboxymethyl cellulose (CMC) by grafting acrylic acid (AA) was studied using single-factor analysis. The optimum preparation conditions were as follows: plasma discharge power of 250 W, processing time of 90 s, pressure of 300 Pa, m(CMC):m(AA) ratio of 1:9, m(K2S2O8):m(CM…
Ferroics include a range of materials classes with functionalities such as magnetism, polarization, and strain. We review coexistence and glassy behavior, as studied over the last decade, in systems such as perovskite manganites, ferroelectrics, and martensites to distil a common theme that includes the interplay of l…
