In 2019, finally, extreme ultraviolet (EUV) lithography has been applied to high volume manufacturing (HVM) for preparing advanced semiconductor devices. That was very important year EUV enthusiasts and industry. Because it takes a long time, more than 30 years, study realizing HVM. With recent rapid progress on the source power improvement, development including photoresist materials achieved ...

Nano-zeolite is an innovative class of materials that received recognition for its potential use in water and tertiary wastewater treatment. These applications include ion-exchange/sorption, photo-degradation, membrane separation. The aim this work to summarize analyze the current knowledge about utilization nano-zeolite these applications, identify gaps field, highlight challenges face wide sc...

With the phasing out of lead-bearing solders, electrically conductive adhesives (ECAs) have been identified as one of the environmentally friendly alternatives to tin/lead (Sn/Pb) solders in electronics packaging applications. In particular, with the requirements for fine-pitch and high-performance interconnects in advanced packaging, nanoconductive adhesives are becoming more and more importan...

The present review article is intended to direct attention to the technological advances made in the 2010-2014 quinquennium for the isolation and manufacture of nanofibrillar chitin and chitosan. Otherwise called nanocrystals or whiskers, n-chitin and n-chitosan are obtained either by mechanical chitin disassembly and fibrillation optionally assisted by sonication, or by e-spinning of solutions...

Excess use of chemical pesticides in agriculture assisting the accomplishment of agri-food production targets. But, indiscriminate use of chemical pesticide is the serious concern for environment and human, which deteriorating the soil health, nutritional quality of food and increasing resistance in phyto-pathogens and pests. Nanotechnology provided the sustainable solution in this regard by de...

Advanced Monte Carlo simulations are used to study the effect of nano-slit confinement on metric and topological properties of model DNA chains. We consider both linear and circularised chains with contour lengths in the 1.2–4.8 μm range and slits widths spanning continuously the 50–1250nm range. The metric scaling predicted by de Gennes’ blob model is shown to hold for both linear and circular...

Preceramic polymers, i.e., polymers that are converted into ceramics upon heat treatment, have been successfully used for almost 40 years to give advanced ceramics, especially belonging to the ternary SiCO and SiCN systems or to the quaternary SiBCN system. One of their main advantages is the possibility of combining the shaping and synthesis of ceramics: components can be shaped at the precurs...

Nanomaterials are known as chemically or biologically engineered materials having nanodimension of 1-100nm. These have been shown to exhibit various novel properties e.g. enhanced reactivity, greater sensing capability and improved mechanical strength. Various improved procedures are still under innovative considerations to enhance the potency, safety, and efficiency of chosen plasmid DNA vecto...
