Summary: Polyimide (PI) aerogels, known for their high porosity, low density, thermal insulation and mechanical strength, have potential applications in aerospace vehicle, intelligent driving and batteries. Traditional molding process limits the practical use of PI aerogels, while 3D printing faces challenges like complex support structures and high thermal conductivity. Here, water-based polyamic acid (PAA)/bacterial cellulose (BC) ink is developed for direct ink writing (DIW) of PI/BC aerogels with improved properties compared to molded ones, making them suitable for thermal insulation in complex structures in fields like buildings and petro-chemical engineering.

Summary: PDMS-based membranes with amine-functionalized and unfunctionalized silica particles were 3D printed for CO2/N-2 gas separation. The printed membranes showed no voids and exhibited desirable thermal and mechanical properties. The inclusion of unfunctionalized silica particles increased gas permeability but compromised selectivity, while amine-functionalized silica improved selectivity. The PDMS/silica membranes demonstrate the potential of 3D printing for carbon capture applications.

Summary: Platinum is an expensive and scarce catalyst, limiting the large-scale commercialization of Pt-based electrochemical devices. The slow oxygen reduction reaction (ORR) with Pt in acidic media has led to the exploration of Pt-free catalysts. This review critically discusses the influence of the physicochemical and electrochemical properties of biomass-derived, carbon-based electrocatalysts for the ORR over the past decade.

Summary: In this study, single atoms and nanoclusters of Fe, Ni, Co, Cu, and Mn were embedded in a well-defined C1N1-type material with internal cavities of approximately 0.6 nm. The nucleation of different metal nanoclusters was achieved by forming metal-nitrogen bonds on four N atoms. After pyrolysis, TM@CNx-type structures were obtained, where TM represents the transition metal and x<1. Fe@CNx and Co@CNx showed promising performance in oxygen reduction reaction and hydrogen evolution reaction respectively, with a Pt-like performance, while Ni@CNx exhibited the highest activity in oxygen evolution reaction (OER) with an E-OER of 1.59 V versus RHE, surpassing the commercial IrO2 (E-OER = 1.72 V). This systematic and benchmarking study provides a basis for the future design of advanced multi-functional electrocatalysts by modulating and combining the metallic nature of nanoclusters and single atoms.

Summary: This study focuses on investigating the sodiation mechanism of non-graphitizing carbons (NGC), and reveals that increasing the pyrolysis temperature leads to NGCs with a more ordered structure and developed closed microporosity. In situ Raman spectroscopy shows that the intercalation of Na+ between the graphene layers occurs mainly during the sloping part of the galvanostatic profile, while the plateau at low voltage can be associated with the filling of micropores with sodium.

Summary: WO3 is a fascinating material for photocatalysis due to its properties of UV-vis absorption, charge carrier transport, and stability against photocorrosion. However, the hydration process of WO3 has been rarely studied, mostly from a theoretical perspective. In this study, a combination of gas sorption experiments and molecular dynamics simulations is used to investigate the hydration mechanisms of WO3. It is found that water molecules adsorb onto the WO3 surface in a two-step mechanism, forming molecular sublayers and subsequent hydrogen bonding to form a complete layer.

Summary: The sluggish kinetics of the oxygen evolution reaction (OER) is a major limitation for green electrochemical devices. Expensive ruthenium and iridium oxide electrodes have been used as advanced electrocatalysts, but their rarity limits their global implementation. Transition metal and boron compounds show promise as alternatives due to their high catalytic properties and stability. However, their synthesis routes often involve expensive supports, increasing the cost. This study presents an easy and support-free synthesis of bimetallic borates, showing improved electrocatalytic properties for OER, particularly with nickel as the transition metal. A support-free synthesis route achieved an overpotential of 230 mV, comparable to commercial and state-of-the-art electrocatalysts.

Summary: Liquid hydrogen (LH2) has the highest storage density with no chemical reaction required, but it needs to be cooled to 20 K using energy-intensive refrigeration. LH2 storage results in the evaporation of LH2, known as boil-off, leading to process inefficiency and energy losses. This review discusses the definition, challenges, state-of-the-art, and recovery strategies to minimize hydrogen evaporation, including zero boil-off (ZBO), hydrogen reliquefaction, and compression solutions. The expertise gained in cryogenic storage for spacecraft has potential applications beyond the industry. Proper integration of reliquefaction systems with LH2 tanks and non-mechanical compressors for boil-off hydrogen offer attractive options for advancing LH2 logistics.

Summary: Even small changes in physicochemical properties of nanoforms (NFs) can influence their environmental fate and hazard. Testing and characterizing each individual NF will not be feasible due to the large number of new materials being developed. Targeting the most relevant form of the NF for a given exposure is important for efficient risk assessment. In aquatic systems, functional fate processes play a key role in determining the exposure relevant form of NFs. Grouping of NFs and read-across based on functional fate pathways can be justified by considering the shared fate and hazard profile. A new Integrated Approaches to Testing and Assessment (IATA) is presented, focusing on dissolution, dispersion stability, chemical transformations, and the contribution to toxicity from particles and dissolved components. This IATA can be used as a template for future in vivo kinetic assessments.

Summary: Compared with vein injection, oral administration is a preferred non-invasive and self-help treatment option for cancer therapy. However, the harsh gastrointestinal tract and biological barriers limit the stability and efficiency of oral drug delivery systems. To overcome these challenges, researchers have developed Cyssome, a drug delivery platform that can maintain stability in harsh environments, penetrate biological barriers, and improve drug release and bioavailability.
