Crystal structure and Hirshfeld surface analysis of (nitrato-κ ,')(1,4,7,10-tetra-aza-cyclo-dodecane-κ )nickel(II) nitrate. | LitMetric

AI Article Synopsis

Article Abstract

The crystal structure of the title compound, [Ni(CHN)(NO)]NO, at room temperature, has monoclinic (2/) symmetry. The structure displays inter-molecular hydrogen bonding. The nickel displays a distorted bipyramidal geometry with the symmetric bidentate bonded nitrate occupying an equatorial site. The 1,4,7,10-tetra-aza-cyclo-dodecane (cyclen) backbone has the [4,8] configuration, with three nitro-gen-bound H atoms directed above the plane of the nitro-gen atoms towards the offset nickel atom with the fourth nitro-gen-bound hydrogen directed below from the plane of the nitro-gen atoms. The nitrate anion O atoms are seen to hydrogen bond to the H atoms bound to the N atoms of the ligand.

Cryogel Addition Effect on Ultrasound-Assisted Thawing of Pork Meat.

Int J Food Sci

December 2024

Laboratory 13 Thermal and Structural Analysis of Materials and Foods, Multidisciplinary Research Unit, National Autonomous University of Mexico-Superior Studies Faculty at Cuautitlan (UNAM-FESC), Cuautitlan Izcalli, Mexico State, Mexico.

The use of new technologies that allow for improving conventional food preservation processes is what the industry has been adopting in recent decades, with high-intensity ultrasound (US) and the application of cryoprotectant agents (cryogels) being those that have become more relevant today. For this reason, in this study, cuts of pork frozen in liquid nitrogen with and without waxy starch cryogel and thawed under controlled conditions in water immersion and with US were used, evaluating thermal parameters such as the initial zone and the melting rate of ice crystals and quality parameters such as pH, water holding capacity (WHC), microstructure, color profile, shear force, and surface changes. It was shown that the addition of cryogel modifies the initial fusion zone, that US-assisted thawing increases the fusion rate, and that both factors influence the quality parameters.

The branched structure of amylose was probed using concanavalin A (ConA) lectin, which forms precipitable aggregates with highly branched glucans, such as glycogen and amylopectin. Rice (japonica cultivar) amylose was fractionated from de-fatted, gelatinized starch by precipitation with 1-butanol (BuOH) and purified by ultracentrifugation and repeated crystallization. The purified amylose still has short side chains, whose chain-length (CL) distribution resembles that of amylopectin.

Unconventional aspects in metal-embedded laser-induced graphene.

Chem Sci

December 2024

Department of Chemistry & Biochemistry, Department of Materials Science & Engineering, California NanoSystems Institute, University of California, Los Angeles Los Angeles CA 90095 USA

Laser-induced graphene (LIG) has gained significant attention, with over 170 publications in 2023 alone. This surge in popularity is due to the unique advantages LIG offers over traditional thermal methods, such as fast, solvent-free, scalable production and its ability to scribe intricate patterns on various substrates, including heat-sensitive materials like plastics. In recent developments, metal-embedded LIG (M-LIG) has expanded the potential applications of LIG, particularly in energy storage, microelectronics, and sensing.

Optical sensors based on plasmonic nano-structures: A review.

Heliyon

December 2024

Faculty of Electrical and Computer Engineering, Semnan University, Semnan, Iran.

Optical sensors are among the most significant optical devices that have found extensive applications for THz sensing. Surface plasmon-based sensors have attracted increasing attention more than other kinds of optical sensors such as photonic crystal, optical fiber, and graphene sensors, owing to their compact footprint, fast reaction, and high sensitivity value. Therefore, this work reviews plasmonic sensor structures divided into three general categories.
