A 2,2'-bipyridine-appended ferrocene rotor, 1,1'-di(5-yl-ethynyl-2,2'-bipyridine)ferrocene, can be switched from a folded/stacked (syn) conformation to an extended/unstacked (anti) conformation by the addition of [Cu(CH3CN)(4)](PF6) and 6,6'-dimesityl-2,2'-bipyridine. This extension and contraction process was completely reversible and could be triggered either chemically or electrochemically.

Renewable and eco-friendly ZnO immobilized onto dead sea sponge floating materials with dual practical aspects for enhanced photocatalysis and disinfection applications

Muhammad Ali Bhatti, Khalida Faryal Almani, Aqeel Ahmed Shah, Aneela Tahira, Iftikhar Ahmed Chana, Umair Aftab, Mazhar Hussain Ibupoto, Abdul Nabi Mirjat, Amal Aboelmaaref, Ayman Nafady, Brigitte Vigolo, Zafar Hussain Ibupoto

Summary: In this study, the role of natural dead sea sponge (DSS) as a host substrate for ZnO immobilization was investigated. The ZnO/DSS hybrid material exhibited excellent degradation efficiency for the removal of methylene blue (MB) dye. This was attributed to the 3D porous structure, high oxidation rate, and charge separation properties of ZnO/DSS.

Amna Altaf, Manzar Sohail, Ayman Nafady, Rashid G. Siddique, Syed Shoaib Ahmad Shah, Tayyaba Najam

Summary: The depletion of fossil fuels and environmental pollution has driven scientists to develop renewable and green energy sources. Photocatalytic water splitting is an effective strategy for producing clean hydrogen fuel in the emerging hydrogen economy. In this study, the photocatalyst (PdO.TiO2) was introduced to accelerate the oxygen evolution reaction (OER) in a photoelectrochemical system. The catalyst demonstrated a significant increase in current density from 0.89 mA/cm2 (dark) to 4.27 mA/cm2 (light) during OER at an applied potential of 0.5 V. With a Tafel slope of 170 mVdec(-1) and an efficiency of 0.25% at 0.93 V, the synthesized PdO.TiO2 material showed promising photocatalytic activity, encouraging further exploration of related catalysts for facilitating OER.

Kinetic Control via Binding Sites within the Confined Space of Metal Metalloporphyrin-Frameworks for Enhanced Shape-Selectivity Catalysis

Weijie Zhang, Zhou Lu, Lukasz Wojtas, Yu-Sheng Chen, Alexander A. Baker, Yi-Sheng Liu, Abdullah M. Al-Enizi, Ayman Nafady, Shengqian Ma

Summary: One striking feature of enzymes is their ability to trap substrates and produce shape-selective products through synergistic or cooperative binding in their enzymatic pocket. In this study, we demonstrate a targeting strategy by anchoring substrates on the internal pore wall of metal-organic frameworks (MOFs), mimicking the enzyme's ability and achieving shape-selectivity for reactions. By investigating metal metalloporphyrin-frameworks (MMPFs) with different densities and distances of binding sites, we show that the structural specificity of MMPFs allows for a facile switch in selectivity, from thermodynamically stable product to kinetic product. Thus, this proposed targeting strategy using porous materials and binding events provides a new approach for developing highly efficient heterogeneous catalysts for shifting selectivity.

A Cross-Sectional Study of Knowledge, Practice, and Management of Solid Waste Segregation in Higher Educational Institutes: A Case Study in KSA

Ragab Rabeiy, Saud Almutairi, Ahmed Birima, Lamyaa Kassem, Ayman Nafady

Summary: Solid waste management is highly considered in the Kingdom of Saudi Arabia for the protection of the environment, preserving resources, and producing energy. A study at Qassim University in Saudi Arabia evaluated the stakeholders' knowledge and practices related to solid waste separation, as well as the current collection system of solid waste on the university's campus. The results showed a high level of awareness among respondents, although waste separation at the generation point was poor. The study suggests the implementation of teaching courses, workshops, and advertisements to increase awareness of the benefits of waste separation at the source.

Exploring the Solid-State Landscape of Carbamazepine during Dehydration: A Low Frequency Raman Spectroscopy Perspective

Peter I. I. I. J. G. Remoto, Karlis Berzins, Sara J. Fraser-Miller, Timothy M. Korter, Thomas Rades, Jukka Rantanen, Keith C. Gordon

Summary: The solid-state landscape of carbamazepine during dehydration was investigated using both low- (-300 to -15, 15 to 300 cm(-1)) and mid- (300 to 1800 cm(-1)) frequency Raman spectroscopy. Density functional theory with periodic boundary conditions was employed to characterize the carbamazepine dihydrate and different forms, which showed good agreement with experimental Raman spectra. The dehydration process of carbamazepine dihydrate at various temperatures (40, 45, 50, 55, and 60 ?) was explored using principal component analysis and multivariate curve resolution, revealing different transformation pathways of solid-state forms. Low-frequency Raman spectroscopy was found to effectively detect the rapid growth and subsequent decline of carbamazepine form IV, which was not as well observed by mid-frequency Raman spectroscopy. These findings highlight the potential benefits of low-frequency Raman spectroscopy in pharmaceutical process monitoring and control.

In Situ Monitoring of Drug Precipitation from Digesting Lipid Formulations Using Low-Frequency Raman Scattering Spectroscopy

Malinda Salim, Sara J. Fraser-Miller, Karlis Berzins, Joshua J. Sutton, Keith C. Gordon, Ben J. Boyd

Summary: Low-frequency Raman spectroscopy (LFRS) is used to detect and track the precipitation of drugs in lipid-based formulations during digestion. Multivariate data analysis and univariate analysis approaches were used to analyze the spectral changes over time and compare the results with small angle X-ray scattering (SAXS) measurements. LFRS was found to be a complementary technique to determine the kinetics of drug precipitation from lipid-based formulations, potentially providing more accessible results than SAXS.

Exploiting reduced-symmetry ligands with pyridyl and imidazole donors to construct a second-generation stimuli-responsive heterobimetallic [PdPtL4](4+) cage

Aston C. Pearcy, Lynn S. Lisboa, Dan Preston, Nick B. Page, Tristan Lawrence, L. James Wright, Christian G. Hartinger, James D. Crowley

Summary: A new sequential metalation strategy has been developed for the assembly of a more stable heterobimetallic [PdPtL4](4+) cage. By using a low-symmetry ditopic ligand (L) with imidazole and pyridine donor units, a [Pt(L)(4)](2+) open-cage complex was selectively formed and then reacted with Pd(ii) ions to assemble the cage C. Various spectroscopy and crystallography techniques confirmed the formation of the cage and its heterobimetallic structure. The cage C exhibited anionic guest molecule binding capability and demonstrated stimulus-responsive behavior.

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.

Reductive cyclodimerization of chalcones: exploring the self-adaptability of galvanostatic electrosynthesis

Mauro Garbini, Andrea Brunetti, Riccardo Pedrazzani, Magda Monari, Massimo Marcaccio, Giulio Bertuzzi, Marco Bandini

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.
