Liquid metal–elastomer composite is a promising soft conductor for skin-interfaced bioelectronics, robots, and others due to its large stretchability, ultrasoftness, high electrical conductivity, mechanical-electrical decoupling. However, it often suffers from deformation-induced leakage, which can smear skin, deteriorate device performance, cause circuit shorting. Besides, antimicrobial property desirable in conductors minimize microbial infections. Here, we report phase separation–based...
Abstract Background A considerable number of studies has been carried out to develop alloplastic bone graft materials such as hydroxyapatite (HAP) that mimic the hierarchical structure natural bones with multiple levels pores: macro-, micro-, and nanopores. Although nanopores are known play many essential roles in bones, only a few have focused on HAPs containing them; none those investigated functions biological systems. Method We developed simple yet powerful method introduce into HAP...
Laser-assisted fabrication of conductive materials on flexible substrates has attracted intense interests because its simplicity, easy customization, and broad applications. However, it remains challenging to achieve laser scribing tissue-like soft elastomers, which can serve as the basis construct bioelectronics actuators. Here, we report metallic conductive, photoactive transition metal oxide (molybdenum dioxide) coated with molybdenum chloride precursors, under ambient conditions....
Synthesizing patchy particles with predictive control over patch size, shape, placement and number has been highly sought-after for nanoparticle assembly research, but is fraught challenges. Here we show that polymers can be designed to selectively adsorb onto surfaces already partially coated by other chains drive the formation of nanoparticles broken symmetry. In our model system triangular gold polystyrene-b-polyacrylic acid patch, single- double-patch are produced at high yield. These...

We demonstrate a strategy for the synthesis of discrete and uniform gold nanorod (GNR)@mesoporous silica (mSiO2) core–shell nanoparticles (NPs) with finely tuned shell thickness by significantly suppressing formation undesired core-free NPs. could control mSiO2 high precision, close to 1 nm, hence rotational diffusion mode NPs simply controlling precursor injection times. The growth on GNR seeds be explained two models based modified LaMer's theory. Between these two, we found most suitable...
African swine fever (ASF) is an obligated declaration disease, provoking farm isolation measures and the closing of affected country boarders. ASF virus (ASFV) currently cause a pandemic across China Eurasia. By end 2019, was detected in nine EU Member States: Bulgaria, Romania, Slovakia, Estonia, Hungary, Latvia, Lithuania, Poland Belgium. The area extended progressively, moving mostly southwestern direction (EFSA). Inactivated and/or subunit vaccines have proven to fail since certain...
Mesoporous silica nanoparticles (MSNPs) are well known for their adhesive properties with hydrogels and living tissues. However, achieving direct contact between the nanoparticle surface adherend necessitates removal of capping agents, which can lead to severe aggregation when exposed wet surfaces. This is ineffective simultaneously bridging two adherends, resulting in a reduced strength. In this study, we designed synthesized mesoporous nanochains (MSNCs) enhance interactions by promoting...
Abstract The gold standard for diagnosing viruses such as the Hepatitis B Virus has remained largely unchanged, relying on conventional methods involving extraction, purification, and polymerase chain reaction (PCR). This approach is hindered by limited availability, it time‐consuming requires highly trained personnel. Moreover, suffers from low recovery rates of nucleic acid molecules samples with copy numbers. To address challenges complex instrumentation rate DNA, a drying process coupled...
Inversion of the role Au(<sc>iii</sc>) chloride allows facile synthesis smooth and spherical AuNPs with nanoscale size tunability.
The limited intragap distance tunability of clustering nanoparticles with different surface chemistries resulted in unwanted interference between embedded and restricted functionality. This leads to an urgent need for a new strategy that enables the assembly building block obtained from solvents polarities defined compositions, distances, orientations. Herein, we used organosilicasome (OSS), organic–inorganic hybrid compound covered surfactant, cluster diverse high configurational regardless...
Endophytic green algae growing in fronds of Grateloupia spp.were examined for infection frequency from their field populations Jeju, Wando, and Uljin, Korea August September 2013.Three endophytes were isolated laboratory culture a G. lanceolata thallus collected Jeju.Unialgal cultures made the endophytes, morphological characteristics observed with light microscopy.In addition, phylogenetic analysis based on chloroplast-encoded elongation factor tufA gene sequences was performed to identify...
The improvement of methane combustion activity was observed in cyclic temperature-programed and isothermal reactions over Pd/ZrO2 catalysts by simple reduction/reoxidation treatment. catalytic increased during the initial stages reaction, light-off temperature lowered as number cycles reaction. To reveal origin activation, variations reduction properties after activation period were carefully investigated through CH4 (TPR) measurements. From CH4-TPR results, it confirmed that decreased...
