Novel kinetic models for both Dumbbell-like and rigid-rod like polymers are derived, based on the probability distribution function f(t, x, n, ṅ) for a polymer molecule positioned at x to be oriented along direction n while embedded in a ṅ environment created by inertial effects. It is shown that the probability distribution function of the extended model, when converging, will lead to well acc...

The micro-Kjeldahl method for nitrogen determination has been widely used in organic chemistry laboratories in recent years. The value of this method, developed through the brilliant researches of PiLcH, BANG, PARNAS and WAGNER, PREGL, and coworkers, has justified its application to industrial and clinical problems. Plant physiologists have not generally adopted quantitative micro-methods for n...

Phytate is the primary source of organic phosphorus, but it cannot be directly utilized by plants and is strongly adsorbed by the soil, reducing bioavailability. Composting is a process used to improve the bioavailability of phytate in organic wastes through degradation by microorganisms. In this study, we aimed to investigate the phytate-degrading ability of fungi and bacteria that inhabit saw...

C. W. Bowen and G. M. Bodner “Problem-Solving Processes Used by Graduate Students While Solving Tasks in Organic Synthesis,” International Journal of Science Education, vol. 13, no. 2, pp. 143-158, 1991. Organic synthesis is the branch of chemistry that deals with the step-by-step conversion of relatively simple starting materials into larger, more complicated, target molecules. Synthesis probl...

This paper presents a new type of capacitor and deals with a hybrid approach where the advantages of two systems, dielectric capacitors and the ultracapacitor are combined. The objective is to increase the capacitance and the energy storage capability, while or at least preserving or decreasing the volume of the passive components. In this aim, the surface area and structural properties of ultr...

Layered metal-organic frameworks and nanosheets have been regarded as an important series of low-dimensional materials. Their flexible designability intrinsic porosity allow layered to be differentiated from inorganic counterparts. The present review article is devoted collecting pieces research aiming at exploiting innovative nanomaterials. Spearheaded by introductory part Section 1, the inclu...

We present a thermal activated solvent bonding technique for the formation of embedded microstrucutres in polymer. It is based on the temperature dependent solubility of polymer in a liquid that is not a solvent at room temperature. With thermal activation, the liquid is transformed into a solvent of the polymer, creating a bonding capability through segmental or chain interdiffusion at the bon...
