Why does the term ‘efficiency’, when applied to the irrigation sector, cause such confusion and misunderstanding? And why is promotion of increased irrigation efficiency likely to hinder achievement of the Sustainable Development Goal (SDG) 6: ‘Water for
Natural gases emanate from the ground passing through tiny pores and fractures in silica rich rocks. These tiny pores alter the behavior of the gases passing through them. To understand the fundamental processes involved in gas migration
A common way to measure water content is by weighting the polymer or a composite sample, using a gravimetric method. This method often overlooks that there is already some water inside the initial (mistakenly called “dry”) material.
In coastal east-central Florida (ECF) in the U.S. (Fig. 1), plant root zone’s (PRZ) subsurface water salinity level is crucial to the survival of various vegetation species because it is one of the dominant factors controlling seed
A healthy and alert clinician is safer and more effective. It has long been known that doctors and surgeons work long and demanding hours with changing shifts, in an environment where the stakes are high. The risk
The effects of H+ and OH− on liquid H2O have attracted much attention by spectroscopic and computer simulation studies. In this work, we offer an alternative approach; from a differential solution thermodynamic. Namely, we use higher order
Friendly supporter or unfriendly disrupter? Understanding extraordinary phenomena under high humidity for novel oxychloride photocatalysts
Water, a strongly polar molecule made up of hydrogen and oxygen, is indispensable for human beings as well as all living organisms. We obtain energy for our activities mostly from oxidation of food, but tracing this back
As simple method for the rapid analysis of radiostrontium in drinking water, river water and seawater
Radiostrontium (mainly strontium-90, 90Sr) belongs to the radionuclides, which are emitted to the environment when nuclear fission gets out of control. The main source is from bomb fallout. Radiostrontium was released to the environment from 1945…1970, when
Water scarcity is one of the main environmental issues humanity is facing. This situation is aggravated by the constant release of refractory contaminants into water reservoirs due to the incessant growth of the industrial activity. These so
Arsenic is an important environmental element because of its high toxicity at the level of parts per billion. According to World Health Organization (WHO) guideline on drinking water quality, the maximum permitted concentration of arsenic in drinking
On a daily basis, we use a variety of personal care products, including soaps, detergents, sunscreens, fragrances, insect repellents, cosmetics, and shampoos. In fact, the US Bureau of Labor Statistics estimates that the average household spends over
Recently, multi-function water treatment agents have attracted much attention. Traditional water treatment agents usually possess single functionality, resulting in production of a wide variety of agents at high doses, complicated devices, and fussy operations in practical applications.
Insoluble suspended colloids are frequently the main contaminants in raw water which make water look very dirty. Moreover, those colloidal particles are usually small and also surface charged, thus the electrostatic repulsion effects among them cause the
Can you think of any very smooth surface in nature or in the man-made objects surrounding you? How about a glass window? Glass is smooth, right? very smooth? Well in reality standard glass substrates, and any other
Metal-organic frameworks (MOF) are well-known crystalline porous materials comprising metal ions or metal clusters bridged by different types of organic linkers. MOFs have been in the spotlight globally owing to their tunable surface area, functionalizable pore surface,
Can solar driven processes effectively control antibiotic resistance and cytotoxicity during drinking water treatment?
Antibiotics, antibiotic resistant bacteria and antibiotic resistant genes have been detected in various aquatic environments because of the disposal of both treated and untreated wastewater. Their occurrence in water is a threat for human and animal health
Lithium ion intercalation for boosting photoelectrochemical water splitting performance of TiO2 photoelectrode
Energy shortage and environmental pollution inspire the exploration of clean, renewable, and non-fossil energy carriers. Hydrogen, as “the world’s cleanest energy” because of its raw materials and products are water, and high energy content per unit mass
A domestic central heating system uses a boiler, powered by electric or gas, to heat water. This is then pumped around the system to radiators that heat a room by radiation and convection. The heat transfer fluid
Ionic liquids are a new class of solvents often claimed as « green » because they are non-flammable and non-volatile. In the search for better environmental industrial processes, they are thus an appealing choice to replace toxic, flammable and
