Article Abstract

Single crystals of KHg(SCN) [dipotassium tetra-thio-cyanato-mercurate(II)] were grown from aqueous solutions of potassium thio-cyanate and mercury(II) thio-cyanate and studied by single-crystal X-ray diffraction. In comparison with the previously reported structure model [Zvonkova (1952 ▸). . , 1798-1803], all atoms in the crystal structure were located, with lattice parameters and fractional coordinates determined to a much higher precision. In the (crystal) structure, the Hg atom is located on a twofold rotation axis and is coordinated in the form of a distorted tetra-hedron by four S atoms of the thio-cyanate anions. The K cation shows a coordination number of eight.

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

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

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.

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.
