This paper summarizes recent developments in foam forming that were mainly carried out in pilot scale. In addition to improving the efficiency of existing processes and allowing better uniformity in material, a wide variety of raw materials can be utilized in foam forming. The focus of this paper is thin webs—papers, boards and foam-laid nonwovens, along with the pilot scale results obtained at VTT in Finland. For paper and board grades, the most direct advantage of foam forming is the potential to produce very uniform webs from longer and coarser fibers and obtain material savings through that. Another main point is increased solids content after a wet press, which may lead to significant energy savings in thermal drying. Finally, the potential to introduce “difficult” raw materials like long synthetic or manmade fibers into a papermaking process enables the manufacturing of novel products in an existing production line. This paper also briefly discusses other interesting foam-based applications, including insulation and absorbing materials, foam-laid nonwovens, and materials for replacing plastics.

In today's rapid growing industries and technology, the frequent use of various insecticide in agriculture sector can be commonly encountered. Insecticides such as carbamate, organochlorine and pyrethroids helps protecting the crop from various insects, which ultimately leads to the better yield of agricultural products. But the main concern that comes out in such frequent practice is the adverse effects to the adjacent ecosystems. Especially, the very commonly used carbofuran, DDT, Cypermethrin and its adverse effects can be put forwarded as a potential example in this article. Apart from this, the scope of this article covers the mechanism of toxicity by insecticides to nontargeted organisms in the ecosystem, the recent developments in the analytical techniques considering HPLC and GC, the method of extraction and quantication of active component in sample. A comparison between GC and HPLC is done and the preferred instrumentation is concluded while considering the analysis of Insecticide. Scope of this review also covers the symptoms and treatment of insecticide poisoning.

Nitrite (NO2 −) has been broadly applied in industrial and agricultural products; it is often found in various foods, water, environmental systems, and biological samples, though NO2 − is a toxic inorganic contaminant that is hazardous to the health of humans and other organisms. In recent years several approaches have been recommended for detecting and monitoring NO2 − that the electrochemical method is of very attention, among them, due to its easy miniaturization, cost-effective, rapidness, straightforward operation. Graphene nanocomposites have a considerable synergistic electrocatalytic effect toward the nitrite redox, magnifying the electrochemical response signals and improving the sensitivity, selectivity, and feasibility of the nitrite detection in various real samples. In this article, we report the recent developments in electrochemical sensors based on graphene/metal nanocomposites for the measurement of nitrate/nitrite in the food samples and identifying performances, including limit of detection (LOD), detection ranges, pH, sensitivity, stability, and technology used were determined.
