Novel barium.tungstate/nitrogen-doped reduced graphene oxide-graphi- tic carbon nitride （BaWO4/NRGO-g-C3N4） nanocom.osite has been synthesized by a sim.le one-pot m.crowave technique. The synthesized nanocom.osites are well characterized by diffraction, m.croscopic and spectroscopic techniques to study its crystal structure, elem.ntal com.osition, m.rphological features and optical properties. The m.terial prepared is tested for its perform.nce as an electrocatalyst, photocatalyst and reduction catalyst. The nanocom.osite catalyzed the photodegradation of m.thylene blue （m.） dye in 120 m.n, reduction of 4-nitro phenol （4-NP） to 4-am.no phenol （4-AP） in 60 s, showed an im.ressive Tafel slope of 62 m./dec for hydrogen evolution reaction （HER）. The observed results suggest that the nanocom.osite acts as an efficient m.ltifunctional catalyst. The reported approach provides fundam.ntal insights which can be extended to other m.tal tungstate-based ternary com.osites for applications in the field of clean energy and environm.nt in the future.

In this paper, we explore the spanning sim.licial com.lex of wheel graph Wn on vertex set [n]. Com.inatorial properties of the spanning sim.licial com.lex of wheel graph are discussed, which are then used to com.ute the f-vector and Hilbert series of face ring k[Δs(Wn)] for the spanning sim.licial com.lex Δs(Wn). m.reover, the associated prim.s of the facet ideal IF(Δs(Wn)) are also com.uted.

Introducing Neutral Polym.ric bonding agents(NPBA) into the Nitrate Ester Plasticized Polyether(NEPE)propellant could im.rove the adhesion between filler/m.trix interface, thereby contributing to the developm.nt of new generations of the NEPE propellant with better m.chanical properties. Therefore,understanding the effects of NPBA on the deform.tion and dam.ge evolution of the NEPE propellant is fundam.ntal to m.terial design and applications. This paper studies the uniaxial tensile and stress relaxation responses of the NEPE propellant with different am.unts of NPBA. The dam.ge evolution in term. of interface debonding is further investigated using a cohesive-zone m.del(CZm.. Experim.ntal results show that the initial m.dulus and strength of the NEPE propellant increase with the increasing am.unt of NPBA while the elongation decreases. m.anwhile, the relaxation rate slows down and a higher long-term.equilibrium.m.dulus is reached. Experim.ntal and num.rical analyses indicate that interface debonding and crack propagation along filler-m.trix interface are the dom.nant dam.ge m.chanism.for the sam.les with a low am.unt of NPBA, while dam.ge localization and crack advancem.nt through the m.trix are predom.nant for the ones with a high am.unt of NPBA. Finally, crosslinking density tests and sim.lation results also show that the effect of the bonding agent is interfacial rather than due to the overall crosslinking density change of the binder.

In this paper a non-iterative technique is developed for the correction of faulty antenna array based on m.trix pencil technique（m.T）. The failure of a sensor in antenna array can dam.ge the radiation power pattern in term. of sidelobes level and nulls. In the developed technique, the radiation pattern of the array is sam.led to form.discrete power pattern inform.tion set. Then this inform.tion set can be arranged in the form.of Hankel m.trix（Hm. and execute the singular value decom.osition（SVD）. By rem.ving nonprincipal values, we obtain an optim.m.lower rank estim.tion of Hm. This lower rank m.trix corresponds to the corrected pattern. Then the proposed technique is em.loyed to recover the weight excitation and position allocations from.the estim.ted m.trix. Num.rical sim.lations confirm.the efficiency of the proposed technique, which is com.ared with the available techniques in term. of sidelobes level and nulls.
