We study the symmetry of Cooper pair in a two-dimensional Hubbard model with the Rashba-type spin-orbit interaction as a minimal model of electron gas generated at a heterointerface of ${\text{SrTiO}}_{3}/{\text{LaAlO}}_{3}$. Solving the \'Eliashberg equation based on the third-order perturbation theory, we find that…

We investigated the nonlinear optical properties of new BaAlBO(3)F(2)(BABF) crystal. The high quality BABF is nonhygroscopic and possesses a moderate birefringence suitable for UV light generation. On the basis of its refractive index dispersion curves, it is inferred that BABF has great potential applications nonline…

Hybrid magnetic nanostructures with high coercivity have immense application potential in various fields. Nickel (Ni) electrodeposited inside Cobalt (Co) nanotubes (a new system named Ni @ Co nanorods) were fabricated using a two-step potentiostatic electrodeposition method. Ni @ Co nanorods were crystalline, and they…

The thermal dehydroxylation of kaolinite has been reexamined using small sample weights, a homogeneous particle size distribution and high‐vacuum conditions in order to reduce the influences of heat and mass‐transfer phenomena. The controlled rate thermal analysis (CRTA) technique, which was specially developed to min…

The linear and nonlinear absorption properties of a squaraine-bridged porphyrin dimer (POR-SQU-POR) are investigated using femto-, pico-, and nanosecond pulses to understand intramolecular processes, obtain molecular optical parameters, and perform modeling of the excited-state dynamics. The optical behavior of POR-SQ…

Bacterial microcompartments (BMCs) are large intracellular bodies that serve as simple organelles in many bacteria. They are proteinaceous structures composed of key enzymes encapsulated by a polyhedral protein shell. In previous studies, the organization of these large shells has been inferred from the conserved pack…

Colloidal PbTe nanocrystals are reacted with AuCl3 in the presence of dodecylamine and tetraoctylammonium bromide in a toluene solution. At room temperature, only homogenous nucleation of isolated Au nanocrystals in solution is observed. At higher temperatures (i.e. 60 °C or higher) the gold ions/atoms are able to dif…

A cyclic porphyrin dimer (Ni 2 −CPD Py ) linked by butadiyne moieties bearing 4-pyridyl groups includes a C 60 molecule inside its cavity in solution to give a 1:1 inclusion complex (C 60 ⊂Ni 2 −CPD Py ). The charge-transfer (CT) band is observed at 645 nm in the UV−vis absorption spectrum of the solution of C 60 ⊂Ni…

We propose a fast two-step switching method of a homogeneous-aligned liquid crystal (LC) cell, where a trigger pulse is applied to align LCs vertically for a moment before they are in-plane switched to show a bright state. Because LCs aligned vertically by a trigger pulse are in a transient state rather than the stabl…
