Large-scale cement production generates significant amounts of carbon dioxide from the breakdown of limestone, contributing to environmental pollution. Clean production of eco-friendly three-dimensional geopolymers can be used as environmentally friendly building materials. Replacing Portland cement with eco-friendly materials correlates with reduced energy consumption, costs, and negative environmental impact. In addition, geopolymer cement has above-average physical and chemical properties, which in many cases exceed conventional Portland cement. The literature review summarizes the latest research in the production of geopolymers following the principles of green chemistry and sustainable development goals. Examples of upcycling of construction waste, industrial waste (fly ash, silica fume, slag, tailing), demolition waste, agriculture solid waste (rice husk, palm oil), and mining waste into functional geopolymer materials will be discussed. Additionally, the review focused on innovative applications and physicochemical properties of functional geopolymer materials.

The rapidly increased efficiency of perovskite solar cells (PSCs) indicates their broad commercial prospects, but the commercialization of perovskite faces complex optimization processes and stability issues. In this work, a simple optimized strategy is developed by the addition of trimethylgermanium chloride (TGC) into FACsPbI precursor solution. TGC triggers the successive interactions in perovskite solution and film, involving the hydrolysis of vulnerable Ge─Cl bond forming Ge─OH group, then forming the hydrogen bonds (O─H···N and O─H···I) with FAI.

Joint presentation - Ecolab and HiTech Health (CDMO for CGT)The purpose of this presentation is to review the impact cleaning and disinfectant residues can present to an ATMP cGMP manufacturing facility and discuss how to assess and manage these residues.The term "disinfectant residue" can illicit different responses. For some, they pose a risk potential product contamination, or can alternatively be seen as evidence that cleaning and disinfection has been performed.

Moisture-electric generators (MEGs), which convert moisture chemical potential energy into electrical power, are attracting increasing attention as clean energy harvesting and conversion technologies. However, existing devices suffer from inadequate moisture trapping, intermittent electric output, suboptimal performance at low relative humidity (RH), and limited ion separation efficiency. This study designs an ionic hydrogel MEG capable of continuously generating energy with enhanced selective ion transport and sustained ion-to-electron current conversion at low RH by integrating an ion-exchange membrane (IEM-MEG).

Background: Using disinfectants and cleaning products (DCPs) at home and work is known to influence both the onset and course of asthma, but most epidemiological studies did not consider the multiplicity and correlations of exposures to DCPs. We aimed to identify exposure profiles for the long-term weekly use of DCPs by latent class analysis (LCA) and assess their associations with asthma.
Methods: LCA was conducted on data from 1143 young adults initially recruited in the German centers of Phase II of the International Study of Asthma and Allergies in Childhood (ISAAC) and followed up three times.
