Solid particles floating at a liquid interface exhibit a long-ranged attraction mediated by surface tension. In the absence of bulk elasticity, this is the dominant lateral interaction of mechanical origin. Here, we show that an analogous long-range interaction occurs between adjacent droplets on solid substrates, which crucially relies on a combination of capillarity and bulk elasticity. We ex...

Introduction A thorough investigation of all equipment in a sugar factory covered by this title would result in a monumental publication. This relatively modest paper purports to draw attention to a few specific aspects of economy in juice heating. Considering the abundance of comprehensive articles on liquid-vapour and liquidliquid heat exchangers appearing in chemical engineering journals it ...

considered to be the cleanest liquid fuel, bioethanol can be a reliable alternative to fossil fuels. it is produced by fermentation of sugar components of plant materials. the common onions are considered to be a favorable source of fermentation products as they have high sugar contents as well as contain various nutrients. this study focused on the effective production of ethanol from an endem...

We report on enhanced experimental optical activity measurements of thin soap films in the presence of sugar. This unusual optical activity is linked to the intramolecular chiral conformation of the glucose molecules at the air/liquid interface. Choosing sodium dodecylsulfate (SDS) as a model surfactant and glucose as model sugar, favorable interactions between the anionic group -OSO3(-)- and t...

Effect of Seaweed Liquid Extract (SLE) of Caulerpa scalpelliformis on growth and biochemical constituents of Vigna mungo was studied. The lower concentration of SLE of C. scalpelliformis (25%) enhanced the percentage of germination, shoot length, root length and biochemical constituents viz., chlorophyll, carotenoid, amino acid, reducing sugar and total sugar contents and α-amylase and β-amylas...

Sugarcane bagasse contains cellulose, lignin and hemicellulose, 39-42%, 20-25% and 25-27% respectively. So it is can be used as a sugar source in many processes. Lignin and hemicellulose must be removed before hydrolysis of cellulose. Several different pretreatment approaches have been studied. The purpose of this research is comparison of acid, ozone and combination of ozone-acid as pretreatme...

It is assumed that the refilling of drought-induced embolism requires the creation of an osmotic gradient between xylem parenchyma cells and vessel lumens to generate the water efflux needed to fill the void. To assess the mechanism of embolism repair, it is crucial to determine if plants can up-regulate the efflux of osmotically active substances into embolized vessels and identify the major c...

We describe several transinterface electron-transfer processes occurring at the benzonitrile (PhCN)/water interface that produce excited states. When an electrode was moved very close to the interface or even through the interface to produce an electrode/thin layer organic phase/aqueous solution configuration, the electrogenerated radical species formed in the PhCN phase (C12-Ru(bpy)3, DPA+, or...
