Article Abstract
Most factories discharge untreated wastewater to reduce costs, causing serious environmental problems. Low-cost, biological, environmentally friendly and highly effective materials for the separation of emulsified oil/water mixtures are thus in great demand. In this study, a simple, green method was developed for separating oil-in-water emulsions. A corn straw powder (CSP)-nylon 6,6 membrane (CSPNM) was fabricated by a phase inversion process without any further chemical modification. The CSPNM showed superhydrophilic and underwater superoleophobic properties and could be used for the separation of oil-in-water emulsion with high separation efficiency and flux. The CSPNM maintained excellent separation ability after 20 cycles of separation with an oil rejection >99.60%, and the oil rejection and flux have no obvious change with an increasing number of cycles, suggesting a good antifouling property and the structural stability of CSPNM. In addition, the CSPNM exhibited excellent thermal and chemical stability under harsh conditions of high temperature and varying pH.

Background: Water contamination is a global challenge, primarily due to heavy metal ions like lead (Pb), iron (Fe), cadmium (Cd), andmercury (Hg) as well as dyes. These pollutants enter the ecosystem from industrial waste and runoff, accumulate in the environment and pose a high risk to humans, animals and plants. Various sensors, such as colorimetric sensors, and electrochemical sensors have been developed to detect these ions and dyes.

Background: Determination of the estradiol hormone in urine is crucial for evaluating congenital adrenal hyperplasia, certain hormone-producing ovarian tumors, polycystic ovary syndrome, liver disease, pregnancy, and infertility. On the other hand, steroid hormones can have destructive effects on the environment, animals, and the endocrine system of humans. Consequently, accurately measuring this hormone's concentration in trace amounts is essential for environmental safety and human health.

Synthetic cathinones (SCs) are drugs of abuse that act on the central nervous system, producing psychoactive effects similar to those of amphetamines. Their greater accessibility compared with the traditional amphetamine-type stimulants has contributed to their increasing popularity in recent years. The analysis of SCs in biological samples is essential for documenting their consumption.

Transparent meltable glasses are keenly desired for making color-conversion layer of Mini-LEDs. In this work, transparent luminescent organic glasses were prepared using a new matrix of heptyltriphenylphosphonium bromide (CHBrP, HTPBr). Through doping of a blue dye (9,10-diphenylanthracene, DPA), the resulting glass exhibited a high transparency (92%) and a blue emission at 436 nm.
