Rapid increase in population and industrialization leads to huge generation of solid waste throughout the country with landfilling as the most common practice for management of these solid waste. It is estimated that out of 3267 MLD of sewage is generated in Delhi. Concentrations of COD, BOD5, heavy metals, NH4AN, low BOD5/COD ratio and the lack of nutrients in the methanogenic phase have restr...

Organic-inorganic hybrid hydrogel electrolytes were prepared by mixing hydrotalcite, cross-linked potassium poly(acrylate) and 6 M KOH solution. The organicinorganic hybrid hydrogel electrolytes had high ionic conductivity (0.456–0.540 S cm) at 30 °C. Moreover, the mechanical strength of the hydrogel electrolytes was high enough to form a 2–3 mm thick freestanding membrane because of the reinfo...

A membrane-less organic-inorganic flow battery based on zinc and quinone species is proposed. By virtue of the slow dissolution rate of the deposited anode (<11.5 mg h-1 cm-2), the battery has a cell voltage of ca. 1.52 V with an average energy efficiency of ca. 73% at 30 mA cm-2 over 12 cycles.

Microalgae have attracted great interest for biofuel production, wastewater treatment, and CO2 capture from dilute sources, but its broad implementation is limited by the high energy consumption of algae dewatering. Membrane technology has emerged as a key process dewatering, performance restrained fouling organic matter in solutions, resulting low water permeance. This review presents state-of...

Abstract Transfer printing based on switchable adhesive that heterogeneously integrates materials is essential to develop novel electronic systems, such as flexible electronics and micro LED displays. Here, we report a robust design of thermal actuated dry adhesive, which features stiff sphere embedded in thermally responsive shape memory polymer (SMP) substrate encapsulated by an elastomeric m...

Membrane biofouling is a major stumbling block in membrane technology and particularly the water treatment industry. Biofouling, particular, serious concern because it irreversible thus cuts lifespan of polymeric membranes. This review, therefore, explores fundamentals development factors that promote biofilm growth systems. In this pursuit, we discuss avenues through which antibiofouling membr...

Black liquor is a highly alkaline liquid by-product of the kraft pulping process, rich in organic molecules (hemicelluloses, lignin, and acids) inorganic chemicals such as sodium salts sulphur-containing compounds. The release this wastewater without further treatment could have serious environmental financial implications. Therefore, costly process used nowadays. Nanofiltration has been studie...

   To fabricate a defect free and high performance mixed matrix membrane (MMM), one approach is the functionalization of inorganic nanofillers (as dispersed phase) in the organic polymer matrix (as continuous phase) to modify the interactions between two phases.  For this purpose,, raw multi-walled carbon nanotubes (rMWCNTs) were purified by acid mixture (HNO3/H2SO<sub...

Forward osmosis (FO) has recently drawn attention as a promising membrane based method for seawater and brackish water desalination. In this study, we focus on the use of calciun chloride (CaCl2) and potassium bicarbonate (KHCO3) as inorganic salt draw solution candidates due to their appropriate performance in water flux and reverse salt diffusion as well as reasonable cost. The experiments we...

1. The effect of osmotic pressure on the nerve resting potential of frog sciatic nerve is in accordance with the assumption of a membrane potential; increased osmotic pressure raises, decreased osmotic pressure lowers the potential. 2. The potential of crab nerves is affected by organic and inorganic cations in the approximate series: Rb > K = diamylamine > dibutylamine > guanidine > tetraethyl...
