Summary: The bacterium strain KC6, identified as Bacillus subtilis, exhibited high resistance to Cd and was able to produce siderophores and solubilize phosphate. KC6 showed strong Cd removal ability under optimal conditions, with Cd bonding onto cell walls and being transported into cellular organs and cytoplasm. Low molecular weight organic acids produced under Cd stress significantly increased, aiding in chelating Cd to Cd-ligands complexes for better removal efficiency.

Summary: In order to ensure environmental and industrial sustainability, the extraction of cadmium ions (Cd(II)) from effluents is necessary. However, achieving high-efficiency Cd(II) extraction has been challenging due to slow rates and low selectivity. This study utilized an ion-imprinting method to imprint Cd(II) onto a thiosemicarbazide-chitosan derivative (TCCS), which was synthesized through an unconventional synthetic route. The developed Cd-TCCS exhibited significantly higher adsorption capabilities and enhanced adsorption selectivity when compared to non-imprinted sorbent.

Summary: The prevalence of pollution in the modern world is largely due to the presence of heavy metals, especially cadmium. Although various chemical and physical methods are used for decontamination, they are often ineffective, expensive, and environmentally unfriendly. Therefore, biological approaches, which involve the use of microbes, have gained attention for their eco-friendly characteristics. This study focuses on the different mechanisms used by microbes to detoxify, absorb, adsorb, and accumulate cadmium. However, the low availability, slow growth, and specific growth requirements of these microbes hinder their feasibility. OMICS approaches, such as genomics and metagenomics, have played a significant role in understanding biological systems and providing critical insights for the removal of heavy metals from the environment.

Summary: Trifolium repens is a potential plant for phytoremediation due to its ability to accumulate heavy metal ions. This study investigated the response of T. repens to high levels of CdCl2 exposure. The results showed that T. repens seedlings exhibited high tolerance to Cd treatment, with higher Cd concentration in the roots distributed in the cell wall. Transcriptomic analysis revealed that genes related to glutathione metabolism and phenylpropanoid biosynthesis were highly expressed in the roots, while those involved in photosynthesis, transferase activity, oxidoreductase activity, and ABA signal transduction were enriched in the leaves. This suggests that T. repens employs multiple mechanisms, such as cell wall biosynthesis and GSH metabolism, to protect itself against Cd stress.

Summary: This study investigated the cell surface reactivity of freshwater cyanobacterium Synechocystis sp. PCC 6803 at varying ionic strengths and found that the cells demonstrated a stronger affinity for Cd in freshwater environments across different pH ranges. These findings suggest that Synechocystis could play a significant role in trace metal cycling in environments with large salinity gradients, such as estuaries and deltas.

Summary: This study found that the biofilm of Scenedesmus obliquus exhibited higher cadmium (II) removal efficiency and greater tolerance to cadmium compared to the suspended form. Pigment inhibition was observed temporarily in Scenedesmus obliquus when exposed to cadmium, but recovered within two days; the extracellular polymeric substance concentration in the biofilm significantly increased on the third day, while protein levels increased in both groups by the end of the experiment. Antioxidant activity was enhanced during the absorption process, with higher activity observed in the biofilm group.

Summary: Biochar sorbents have recently gained attention due to their environmental friendliness, strong remediation capabilities, and low cost. In this study, fish scale biochar (FSBC) was investigated for the first time as an alternative material to eliminate toxic cadmium ions from contaminated water. The effects of various parameters on the biosorption performance were explored, and the results showed that FSBC had a high Cd2+ removal efficiency in both batch and fixed-bed experiments. The biosorption/desorption potential of FSBC was also evaluated, and it was found to be suitable for long-term utilization. Through various analyses, it was concluded that FSBC has a good ability to bind and remove Cd2+ ions, even from real effluent samples.

Summary: Residual algal biomass, a by-product of value-added product extraction, can be a large and low-cost source of biosorbents. The biosorption of heavy metals by residual biomass of Chlorella vulgaris was studied under various conditions. The biosorption capacities of the residual biomass were higher than that of dried biomass, primarily due to increased specific surface area.

Summary: The biosorption behavior of arsenic(V) and cadmium(II) ions by unmodified and chemically modified Chlorella vulgaris and Spirulina platensis was studied. NaCl and ZnCl2 were found to be the most suitable modifiers for enhancing biosorption performance. The pseudo-second-order kinetic model fitted well with all biosorption processes, indicating the potential application of chemically modified algae biomasses for effective removal of arsenic(V) and cadmium(II) from water.

Summary: Femtosecond optical measurements provide ultrafast dynamics information of photoexcitable molecular crystals with structural sensitivity. This study combines excitation theory with birefringence decomposition calculation to retrieve linear and non-linear population transfer in photoexcited crystals. A computational tool based on this treatment is developed for modeling electric field decomposition, dipole projections, and non-linear excitation population levels.

Summary: A population study was conducted on four colors of Pakistani ballpoint pen inks commonly used in the market. UV/Vis spectroscopy and FTIR spectroscopy were used to investigate and discriminate the ballpoint pen inks. The results were compared in terms of discriminating power (DP), and statistical techniques were applied for data analysis. The study found that green ballpoint pen inks had the highest DP when using UV/Vis and FTIR techniques. Black and red inks showed the highest DPs using UV/Vis spectroscopy, while blue ink achieved the highest DP using FTIR spectroscopy. Using chemometric techniques improved the DP and obtained higher DPs compared to visual examination.

Summary: Electrochemical sensors based on carbon paste electrodes modified with Zinc oxide (ZC) and Zinc Oxide-Copper-Benzene Tricarboxylic acid (ZBC) were fabricated for voltammetric estimation of toxic Cd (II) ions. The synthesized materials were characterized and mixed with appropriate amounts of graphite powder and paraffin oil to generate a variety of modified carbon paste electrodes. The optimized conditions for Cd(II) ions determination were determined using potentiostat workstation. ZBC showed better performance than ZC, with lower LOQ and LOD, larger surface area, and smaller electrode modifier amount.
