Summary: The number and behavior of stem cells vary along the intestinal tract, with small intestines having twice as many effective stem cells as large intestines. This difference is attributed to the presence of retrograde cellular movement in small intestines, which allows cells positioned away from the crypt base to function as long-term effective stem cells.

Summary: This study evaluated the effectiveness of post-culture liquid medium from SCOBY in protecting Scotch pine wood samples against decomposition by the fungus Coniophora puteana. Results showed that impregnation of wood with the post-culture medium reduced the likelihood of wood decomposition by the test fungus. The potential biocidal effect was attributed to substances of potential fungicidal nature synthesized during metabolic processes in the culture medium, encouraging further research on the use of metabolites from SCOBY in wood protection against biodegradation.

Summary: Photosystem II of oxygenic photosynthesis is found in the thylakoid membranes of plastids and cyanobacteria. The central core of PS II is surrounded by low-molecular-weight subunits, with additional hydrophilic subunits found associated with the core proteins. Mutant strains with different combinations of extrinsic proteins and PsbJ were used to investigate their cooperation during PS II assembly, with results showing that PsbJ can bind to PS II without the extrinsic proteins, but certain combinations were unable to support oxygen evolution.

Summary: With increasing energy consumption and greenhouse gas emissions, developing renewable energy sources to replace fossil fuels has become crucial. Hydrogen production through water electrolysis powered by renewable energy systems is an essential measure to reduce emissions. However, challenges exist in seawater electrolysis, such as undesired chlorine gas reaction and corrosion, making the development of new electrocatalysts for seawater electrolysis urgent.

Summary: This study aims to understand the influence of drying methods on the solvent evaporation rate and material quality in the large-scale production of NMC cathodes, comparing the conventional vacuum oven used in laboratories with the industrial convection drying method. By studying the drying kinetics and their impact on surface cracks and binder migration, it was found that different drying conditions lead to structural differences, highlighting the importance of implementing drying conditions that represent the industrial process in laboratories.

Summary: The purpose of this study is to explore the potential and limitations of first-generation electric aviation technology, and emphasize Norway's geographical advantages and unique regional network. Electric flight distances of up to 400 km could cover 77% of all flights within Norway. There is limited research on the suitability of battery-powered all-electric aviation in such scenarios, making Norway an ideal case study location. Key factors such as battery technologies, propulsion systems, aircraft designs, and flight profiles are investigated to evaluate the feasibility of specific routes in terms of power, energy, and battery size. A case study of different flight distances in Norway (77-392 km) and two aircraft types (one retrofitted with electric powertrain and one specifically designed for electric drivetrain) is presented. While the completely redesigned aircraft meets the power requirements of the routes, modest improvements in battery energy density would enable retrofitting of existing aircraft. The study concludes that operating small electric aircraft (with 9-39 passengers) on short-haul flights in Norway is feasible through new designs or retrofitting.

Summary: Understanding and mitigating battery degradation is crucial for financial and environmental reasons. This study examines how degradation affects heat sources in batteries, emphasizing the need for dynamic cooling strategies throughout battery life. The research focuses on reversible and non-reversible heat sources in a commercial lithium-ion battery, and investigates the impact of thermal management strategies on degradation and cooling efficiency. The findings indicate that entropic heating plays a significant role in heat generation, resulting in temperature variations and increased thickness as the battery degrades.

Summary: Bicarbonate (HCO3 (-)) binding is crucial for electron flow regulation in PS II, and the D2 subunit of PS II plays a key role in stabilizing HCO3 (-) ligation. Mutations in the D2-Lys264 residue affect the assembly and activity of PS II. The K264E mutant shows slower growth and inhibited oxygen evolution, while the K264A mutant is more susceptible to high-light-induced photodamage. Both mutations impair electron transfer between Q(A) and Q(B) and retard plastoquinol exchange at the Q(B)-binding site.

Summary: The wavelengths of light harvested in oxygenic photosynthesis are typically between 400 and 700 nm. Cyanobacteria can adapt to far-red light by up-regulating alternative copies of various proteins, including D1(FR), to support photosynthesis. Incorporating D1(FR) into Synechocystis 6803 resulted in low rates of oxygen evolution and an inability to support photoautotrophic growth. Mutations in helix A, resembling D1(FR) residues, produced a similar phenotype, while changes in helices B and C had minor effects on photoautotrophy but impacted the function of PS II.

Summary: The cost and environmental impact of lithium-ion batteries (LIBs) can be reduced by using water as a solvent and bio-derived kraft lignin as a binder material to fabricate high-density, thick NMC111 cathode coatings. The performance deterioration at high discharge currents is amplified by high mass loading and low bulk porosity. Lithium-ion diffusion limitation at current densities higher than 0.2 C is mitigated by creating line structures on the cathode surface.

Summary: This study explores the possibility of using abundant, bio-derived kraft lignin as a binder to replace or partially replace commonly used PVDF and CMC binders in water-based processing of Ni-containing LiNixMn1-x-yCoyO2 cathodes. The results show that comparable specific capacities to NMP/PVDF-based cathodes can be achieved with lignin or CMC/lignin as binder materials. Kraft lignin undergoes a redox reaction with the electrolyte, but its binding abilities to carbon and its thermal stability make it a promising alternative binder material for aqueous processing of high capacity cathodes.
