As dermatology has evolved into a medical/surgical specialty, care for the patient with difficult postsurgical wounds has emerged as an aspect of practice for an increasing number of dermatologists. Here, we present a transforming powder dressing which yielded fast, cost-effective healing of two such wounds, while also relieving the patient and his family of any wound care responsibility.

Solid-liquid biphasic absorbents are a promising solution for overcoming the high-energy consumption challenge faced by liquid amine-based CO capture technologies. However, their practical applications are often hindered by difficulties in separating viscous solid-phase products. This study introduces a novel nonaqueous absorbent system (PD/PZ/NMP) composed of 4-amino-1-methylpiperidine (PD), piperazine (PZ), and -methyl-2-pyrrolidone (NMP), engineered to produce easily separable powdery products.

Sustainability and environmental protection are reshaping industries, including construction, where sustainability plays a crucial role in its influence on global resource consumption and waste management. The current study has developed a reusable cement material by photo-chemical surface modification of marble powder, achieved by reacting glycidyl methacrylate with carbonate functionality. This innovative modified marble powder boosts the reusability of construction materials, unlocking new possibilities for sustainable building practices.

Increasing healthcare costs, limited healthcare resources, an aging population, and lifestyle-related diseases make wound management a growing clinical, social, and economic burden. This case series investigated the use of a novel, biocompatible, polymer-based transforming powder dressing (TPD) that transforms in situ to a shape-retentive wound matrix upon hydration for treating wounds of various etiologies.In this institutional review board-approved single-center retrospective case series, the researchers evaluated various acute and chronic wounds treated with TPD over a period of 2 years.

Photocatalytic water splitting holds great potential for transforming solar energy into valuable chemical products. However, obstacles such as the rapid recombination of electron-hole pairs and insufficiently active surface areas of photocatalysts remain significant challenges. In this study, we present the first demonstration that lithium bis(trifluoromethanesulfonyl)imide vapor successfully etches aluminum from NbAlC MAX phase powders while concurrently forming NbOF anchors on NbCT nanosheet (NbCTNS) MXene, leading to the in situ formation of a NbCTNS/NbOF heterostructure composite.

With the aim of transforming sewage sludge into a P-fertiliser material in a single combustion step, the chemical processes underlying sewage sludge combustion were analysed using powder X-ray diffraction (P-XRD), infrared spectroscopy (IR), thermogravimetric (TGA) as well as elemental analyses (EA). In addition to the combustion of sewage sludge on its own ("mono-combustion"), additions of different additives prior to the combustion step were also carried out. Based on the very positive effects of the additives sodium and potassium carbonate on the obtained ashes concerning their phosphate solubilities in neutral ammonium citrate (NAC) solution, sewage sludge combustions after additions of NaCO or KCO were investigated in detail.
