A well-known organic host compound undergoes single-crystal-to-single-crystal phase transitions upon guest uptake and release. Despite a lack of porosity of the material, guest transport through the solid occurs readily until a thermodynamically stable structure is achieved. In order to actively facilitate this dynamic process, the host molecules undergo significant positional and/or orientatio...

porous niti alloys has a series of unique properties such as shape memory effect, superelastic behavior and energy absorbability that make them usable in a wide range of medical and industrial appliances. but the more probability of ni release from a porous niti compare to the nonporous one has restricted it’s uses in implants. in the present research for resolving the problem, performing a cal...

This work describes the gasification of carbon produced during pyrolysis methane. Carbon was deposited on nonporous α−Al2O3 at temperatures ranging between 950 and 1150 °C. The time in contact with methane varied 60 8400 s. Gasification tests were performed range 1000 to 1100 °C steam, CO2 air used as oxidizer. It observed that rate cannot be described by only parameters related conditions (tem...

Given the exceptionally high thermal stability of poly (para-phenylene) (PPP) among linear polyaromatics, it is expected that PPP fibers will have myriad applications. In this study, were obtained starting from enzymatic dihydroxylation/reduction benzene to 5,6-cis-dihydroxycyclohexa-1,3-diene, followed by esterification, polymerization, and aromatization. Polymer precursor was characterized in...

The search for novel natural ingredients has been stimulated by the food and non-food industries, roots of Pachyrhizus erosus (jicama) emerges as promising crops industrial production due to its crispy succulent flesh high yield. Therefore, jicama starches from Fujian Province (SFJ) Guangxi (SGX) were isolated microstructure, swelling power, crystallinity, thermal property, rheological in vitro...

Herein, three boranes are studied as potential precursors of boron nitride (BN) and their carbon dioxide adsorption capacity is evaluated. The selected ammonia borane (AB, NH3BH3), lithium amidoborane (LiAB, LiNH2BH3), sodium (NaAB, NaNH2BH3), they pyrolyzed at four different temperatures. All the characterization techniques show formation BN from boranes. However, LiAB NaAB form hexagonal (h-B...

The pyrolytic conversion of methane for the production hydrogen and carbon was investigated over nonporous α-Al2O3 surfaces in range 900–1300 °C. Two devices were used: i) a single particle reactor to determine deposition rate at various temperatures ii) fixed bed which both measured. It observed that 1000 °C below, selectivity towards (and hydrogen) initially low fresh (e.g. 38% 250 s reaction...
