Bicyclo[1.1.1]pentane (BCP) motifs are of growing importance to the pharmaceutical industry as sp3-rich bioisosteres benzene rings and molecular building blocks in materials science. Herein we explore behavior 1,3-disubstituted BCP moieties on metal surfaces by combining low-temperature scanning tunneling microscopy / non-contact atomic force studies with density functional theory modeling. We ...

This work consists in investigating the influence of structural changes induced by annealing, such as presence a rigid amorphous fraction (RAF) and crosslinking, on mechanical properties polyphenylene sulfide (PPS) fracture behavior (particularly tenacity) Carbon/PPS laminated composite. The first part study aimed at obtaining PPS samples with different amounts RAF, determining conditions poten...

This paper investigated the effects of combining fibers with self-consolidating concrete (SCC). 12 series of test specimens were prepared using three kinds of fibers including steel, polyphenylene sulfide (PPS) and glass fibers with four different volumes fractions and one specimen without fibers as a reference sample. All plans were subjected to fresh concrete tests. For mechanical behavior of...

Abstract Ubiquitous use of electronic devices has led to an unprecedented increase in related waste as well the worldwide depletion reserves key chemical elements required their manufacturing. The biodegradable and abundant organic (carbon-based) materials can contribute alleviate environmental impact industry. pigment eumelanin is a bio-sourced candidate for environmentally benign (green) elec...

the preparation of nanostructure type manganese oxide and cobalt oxide materials with the smallest particle size is reported here. the nanorod manganese oxide and cobalt oxide nanotube were prepared via a sol-gel reaction in reverse micelles from kmno4 and cocl2 with respectively source at room-temperature. the structure and surface morphology of the obtained manganese oxide were studied by mea...

the improvement of the physical properties of indium tin oxide (ito) layers is quite advantageous in photovoltaic applications. in this study the ito film is deposited by rf sputtering onto p-type crystalline silicon (c-si) with (100) orientation, multicrystalline silicon (mc-si), and glass substrates coated with zno and annealed in vacuum furnace at 400°c. electrical, optical, structural and m...
