Summary: DNA has gained popularity as a next-generation storage medium due to its high density and stability. To overcome the challenges posed by using long double-stranded DNA for storage, we have designed a highly robust coding scheme called the random code system. In biological experiments, we have successfully stored a significant amount of data in DNA chains, demonstrating the potential for robust DNA-based data storage using the random code system.

Summary: In this article, a novel omnidirectional wireless power transfer system based on double-toroidal helix coils is proposed and studied. The suggested antenna creates two mutually orthogonal magnetic fields through the double-helix coil wounded around a torus. The system consists of three transmitter-repeater pairs orthogonal to each other, ensuring omnidirectional functionality. Experimental results confirm self-tunability and high efficiency for any position and orientation of receivers.

Summary: In this study, we developed two methods to test equilibrium and estimate double reduction rates in autopolyploids. One method is based on maximum likelihood approach, and the other is based on U-statistic minimization approach. We also developed a bootstrap procedure based on the U-statistic for testing equilibrium in small sample sizes and uncertain genotypes.

Summary: The study demonstrates the controlled transition of PLG between alpha-helix and random coil conformations using chemical energy flow. By adjusting the amount of chemical fuels and nucleophile, the lifetime and content of transient alpha-helices can be tuned. This fuel-mediated coil-helix transition of polypeptides presents an efficient strategy for mimicking the behavior of dynamic proteins found in natural systems.

Summary: This study investigated the four-phase equilibrium conditions of carbon dioxide + cyclopentane double clathrate hydrate forming systems coexisting with sodium chloride aqueous solution or pure water. The results showed that the double clathrate hydrate is more thermodynamically stable than simple clathrate hydrates under a given sodium chloride concentration.

Summary: In the past thirty years, the study of unfolded proteins has gained significant interest due to the discovery of intrinsically disordered proteins which share similarities with unfolded proteins while having various functions. Research on both unfolded and disordered proteins has shown that their conformational properties can deviate from random coil behavior in specific regions. Studies on short peptides have indicated that different amino acid residues have varying sampling degrees within the allowed space of the Ramachandran plot. This article reviews the research on short peptides to explore the conformational distributions of amino acid residues in different contexts, using experimental and computational methods.

Summary: A novel magnetic rhamnolipid-activated layered double hydroxides nanocomposite was prepared for the simultaneous adsorption of Cu(II) and m-cresol from aqueous solution. The nanocomposite showed platelet-like morphology and exhibited excellent adsorption kinetics and thermodynamics for both Cu(II) and m-cresol. The magnetic property allowed for easy separation and recovery of the adsorbed pollutants, showing great potential for simultaneous remediation of organic and heavy metal pollutants.

Summary: This study found that functionalizing activated sand with Mg-Fe and Ni-Fe layered double hydroxides can enhance the efficiency and capacity of adsorbing phosphate. The optimum conditions for adsorption were determined to be 1000 mg/L initial phosphate concentration, 1 g adsorbent dose, pH 7-7.5, and a temperature of 298 K.

Summary: This paper reports force field parameters for DNA and demonstrates their accuracy and applicability. By modifying and adjusting existing models, the parameters achieve a level of accuracy comparable to or even superior to state-of-the-art nucleic acid force fields. Furthermore, the parameters can be used for long-timescale simulations of protein-nucleic acid complexes.

Summary: Layered double hydroxides (LDH) have attracted significant attention due to their flexible chemical composition and physical properties. In this study, M (Mg and Zn)-Fe LDH were synthesized under different conditions and their potential for separating ARD from aqueous solutions was investigated. It was found that Mg-Fe LDH exhibited a higher adsorption capacity for ARD compared to Zn-Fe LDH.

Summary: In this article, a novel catalytic reaction using Pd(0) and Bronsted acid is reported for the synthesis of biologically important imidazolidinone-fused N-heterocycles through redox-neutral intramolecular N-allylation of indoles and pyrroles with alkynes. This atom-economical method is applicable to a wide range of substrates and eliminates the need for leaving groups or oxidizing agents commonly used in traditional allylation reactions.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.

Summary: In this study, the synthesis of functionalized benzo[a]phenazines and indazolo[2,3-a]quinolines was achieved through Rh(III)-catalyzed oxidative annulation of 2-arylquinoxalines and 2-aryl-2H-indazoles with allyl alcohols. The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
