Co-based spinel oxides with unique crystal structures have been identified as a class of promising candidates for alkaline water oxidation catalysis in oxide structural families.

We present a novel nuclear targeting nanoprobe based on peptide functionalized gold nanoparticles and its surface-enhanced Raman scattering (SERS) in living cells. For the first time, we probe an original SERS signal from cell nucleus by using high-selectivity nanoparticles. The conjugated with SV-40 large T localization (NLS) successfully enter after incubation Hela cells deliver spatially localized chemical information of nucleus, as well signature chemicals that intruded subsequently....

The ubiquitous deployment of Internet Things (IoT) devices enhances connectivity and communication, benefits almost every aspect our lives from manufacturing to retail smart homes. However, low levels security protection in these due their limited resources open opportunities for malicious users. An IoT forensics system collecting, processing, analyzing reporting evidence attack is required mitigate the issues. Although such has been studied over past decade solutions as cloud-based forensic...

Vehicular sensing is advocated to perform data collection by exploiting a plethora of vehicular on-board sensors; meanwhile, with the merging and fog computing, deployed road side units (RSUs) can act as nodes collect share sensory at network edge. However, there are still several problems in terms secure reliable sharing fog. To resolve these issues, this paper, we present an efficient, privacy-preserving verifiable scheme permissioned blockchain During phase, combining homomorphic 2-DNF...

Abstract The electroreduction of nitrate (NO 3 RR) to ammonia (NH ) provides a promising solution enable environmental remediation caused by ‐containing waste and also allows for energy‐saving NH generation. Adsorption *NO 2 intermediate may be strengthened decrease byproducts (e.g., favor the eight‐electron NO RR into . In this work, copper‐incorporated O‐vacancy containing Ti C MXene (Cu@Ti O v is reported, which cooperatively inhibits production facilitates hydrogenation, leading...

Abstract Cells are complex chemical systems, where the molecular composition at different cellular locations and specific intracellular interactions determine biological function. An in-situ nondestructive characterization of complicated processes (like e.g. apoptosis) is goal our study. Here, we present results simultaneous three-dimensional imaging double organelles (nucleus membrane) in single HeLa cells by means either labelled or label-free surface-enhanced Raman spectroscopy (SERS)....

Abstract Ordered intermetallic compounds, one of the most effective alloying ways enhancing electrocatalytic activity may provide more active sites for intermediates adsorption in single catalytic reactions. However, catalysis involving several starting materials (such as co‐catalytic synthesis urea from CO 2 and NO 3 ⁻), it typically cannot favor multiple adsorption, leading to preferred individual preventing C─N coupling. As a proof concept, AuCuIrCo medium‐entropy (MEI) compounds are...

A simple method of fabricating shape-tunable Au nanopeanuts from Au–Ag core–shell nanoparticles based on both galvanic replacement and reagent reduction is described.

Abstract In surface‐enhanced Raman scattering (SERS), the scattered intensity is drastically increased due to a resonant interaction with surface plasmons of coin metals. SERS nondestructive spectroscopic method applied also biomedical samples. It inherits advantages normal spectroscopy and at same time overcomes inherent low sensitivity problem. These properties endow exciting opportunities be successful analytical tool for cell analysis. can used detect only molecules located on or close...

This paper examines the impact of a polyvinylidene fluoride (PVDF) and carbon nanotube (CNT) hybrid coating on heat transfer hydraulic performance serpentine microchannel sinks. In an aluminum sink using deionized water as working fluid, flow resistance were analyzed for different mass fluxes (G) in both PVDF-CNT coated (PSMC) uncoated (TSMC) sinks under densities. The results demonstrate that enhances channel. Compared to TSMC, convective coefficient PSMC increased by up 61.9%, while...

Self-Organizing Network (SON) has been introduced more than a decade by the Next Generation Mobile Networks (NGMN) and later standardized 3rd Partner-ship Project (3GPP). However, SON ever never fully met expectation from Operators (MNOs) since day one due to lack of suitable wireless based Machine Learning (ML) techniques which can empower with intelligence in old days. The authors propose, validate, productize ML scheme ISO-SON mitigate cell coverage interference problems 4G Long Term...

Self-Organizing Networks (SON) is an automation technology making the planning, deployment, operation, optimization, and healing of networks simpler faster. Legacy SON targeted at network optimization through certain rules policies which are globally applied in networks. However, scalable not considered yet 3GPP. Furthermore, driven by performance rather than ultimately improving user Quality Experience (QoE). The impact application characteristics on further QoE also 3GPP SON. This paper...

In Identity-Based Encryption (IBE) systems, key revocation is non-trivial. This because a user's identity itself public key. Moreover, the private corresponding to needs be obtained from trusted authority through an authenticated and secrecy protected channel. So far, there exist only very small number of revocable IBE (RIBE) schemes that support non-interactive revocation, in sense user not required interact with or some kind hardware renew her without changing (or identity). These are...
