We present a fast and effective electrochemical method to purify random networks of single-walled carbon nanotubes (SWCNTs) that leads to total removal of metal catalyst without apparent detrimental effect on the electrochemical properties of the electrodes. The efficiency of the electrochemical purification has been compared with that of conventional chemical purification (acid washing). The d...

The removals of NOx by catalytic technology at low temperatures (100–300 °C) for industrial flue gas treatment have received increasing attention. However, the development of low temperature catalysts for selective catalytic reduction (SCR) of NOx with ammonia is still a challenge especially in the presence of SO2. The current status of using Mn-based catalysts for low temperature SCR of NOx wi...

Determining effective cleaning and disinfection regimes of livestock housing is vital to improving the health of resident animals and reducing zoonotic disease. A cleaning regime consisting of scraping, soaking with or without detergent (treatment and control), pressure washing, disinfection and natural drying was applied to multiple pig pens. After each cleaning stage, samples were taken from ...

INTRODUCTION Inadequate hand-washing facilities have been reported as a barrier to hand washing. This study aimed to evaluate the availability and accessibility of hand-washing facilities and supplies of hand-washing agents in the outpatient department (OPD) complex of a tertiary care teaching hospital. METHODOLOGY A checklist containing 13 variables was prepared and all rooms of direct patie...

We evaluated the microbial contamination of 17 types of vegetable and 10 types of fruit after 30-s washing with tap water with and without subsequent disinfection by 10-min immersion in 0.01% (100 ppm) sodium hypochlorite. The mean microbial contamination level of 9 types of leafy vegetable was 2.8 x 10(5) colony-forming units (CFU)/g after washing with water and 3.4 x 10(4) CFU/g after washing...

BACKGROUND More than 95% of neonatal deaths occur in developing countries, approximately 50% at home. Few data are available on the impact of hand-washing practices by birth attendants or caretakers on neonatal mortality. OBJECTIVE To evaluate the relationship between birth attendant and maternal hand-washing practices and neonatal mortality in rural Nepal. DESIGN Observational prospective ...

Nanoparticles have experienced increasing interest over the past three decades owing to development of new synthesis methods and adaptation analysis tools with spatial resolutions below one micrometer. Among different types nanoparticles developed in recent years (metals, metal oxides, silica, polymers, etc.), significant scientific has around iron oxide nanoparticles. This review will focus on...

The removal of transition metal ions is crucial for improving the efficiency of subsequent peroxide bleaching. Acid-washing and chelation have been proposed for such a purpose. However, their influences on the Mg(OH)2-based peroxide bleaching of hardwood pulps at a high consistency have not been well documented in the literature. In this work, we studied the influence of acid-washing using sulf...

This paper reports fabric circuit boards (FCBs), a new type of circuit boards, that are threedimensionally deformable, highly stretchable, durable and washable ideally for wearable electronic applications. Fabricated by using computerized knitting technologies at ambient dry conditions, the resultant knitted FCBs exhibit outstanding electrical stability with less than 1% relative resistance cha...

While phosphoproteins have attracted great interest toward the post-genome research (e.g. clinical diagnosis and drug design), there have been few procedures for the specific enrichment of native phosphoproteins from cells or tissues. Here, we describe a simple and efficient protocol to enrich phosphoproteins comprehensively from a complex mixture containing solubilized cellular proteins. This ...
