For sodium-ion batteries, nickel telluride (NiTe) is an excellent anode material. However, significant volume changes and slow kinetics compromise its structural stability and its capacity for high-current reactions. To increase sodium storage performance, NiTe nanoparticles are synthesized in situ within hollow porous carbon spheres (NiTe@HPCS) through a "drop-dry" process, vacuum-assisted adsorption, and vapor tellurization.

Article Synopsis
  • Chlorophyll is crucial for photosynthesis but can cause oxidative damage if overproduced, especially in cyanobacteria, which are ancient photosynthetic organisms.
  • The enzyme chlorophyll synthase (chlG) plays a key role in chlorophyll production, but its regulation is not fully understood; the transcription factor RppA binds to chlG's promoter and represses its expression.
  • The study found that knocking out rppA led to increased chlorophyll and oxidative stress in cyanobacteria during light transitions, while RppA also promotes carotenoid biosynthesis to mitigate oxidative damage.

Some colorectal cancer patients have experienced normal epithelial transformation into inflammatory and tumor states, but the molecular basis still needs to be further determined. The expression levels of SIX4 are gradually increased in dextran sodium sulfate (DSS) and azoxymethane (AOM)/DSS-induced colonic epithelial inflammation and tumors, respectively, in mice. Targeting SIX4 alleviates intestinal inflammation occurrence and reduces adenoma formation in mice.

Anti-icing gels inhibit ice formation and accretion; however, current iterations face prevalent drawbacks such as poor strength, weak substrate adhesion, and limited anti-icing properties. Herein, we propose a novel approach to address these challenges by developing a thermomechanical robust polyionic elastomer (PIE) with enhanced anti-icing properties. The PIE surface exhibits an icing delay time up to 5400 s and remains frost-free after exposure to -10 °C for 3.

Article Synopsis
  • Mitochondria are like tiny power plants in our cells that create energy, and they rely on special proteins to do this job.
  • A key enzyme called SUCLG1 helps control these proteins by managing a substance called succinyl-CoA, which affects the way another important protein, POLRMT, works with mitochondrial DNA.
  • In leukemia, certain mutations can boost SUCLG1 levels, improving mitochondrial production and helping cancer cells grow, but reducing SUCLG1 or POLRMT can slow down the disease.

Purpose: Stereotactic body radiation therapy (SBRT) versus surgery for operable early-stage non-small cell lung cancer (ES-NSCLC) remains highly debated. Herein, we used spatial proteomics to identify whether any molecular biomarker(s) associate with the efficacy of either modality, in efforts to optimize treatment selection between surgery and SBRT for this population.

Methods And Materials: We evaluated biopsy tissue samples from 44 patients with ES-NSCLC treated with first-line SBRT (cohort 1) by GeoMx Digital Spatial Profiling (DSP) with a panel of 70 proteins in 5 spatial molecular compartments: tumor (panCK+), leukocyte (CD45+), lymphocyte (CD3+), macrophage (CD68+), and stroma (α-SMA+).

Abortive transcripts (ATs) refer to nascent 2-10 nucleotides (nt) RNAs released by RNA polymerases before synthesizing productive RNAs. The quantitative detection of ATs is important for studying transcription initiation and the biological function of ATs; however, no method is available for the qualitative and quantitative assessment of such ultra-short oligonucleotides (typically shorter than 11 nt) in vivo at present, even with the LNA probes, the detection limit can only reach 11 nt. Here, we demonstrated the base stacking hybridization assisted ligation (BSHAL) technique, combined with TaqMan-MGB qPCR, can detect 4-10 nt ATs with a specificity of nucleotide resolution and a sensitivity of approximately 10 pM.

Article Synopsis
  • Researchers developed a 3D carbon fiber film embedded with gradient Cu nanoparticles (CFF@Cu) to improve Zn plating and stripping performance for metal Zn anodes.
  • The CFF@Cu configuration significantly enhances zinc deposition stability and prevents dendrite formation during operations lasting up to 2000 hours at varying current densities.
  • This improvement is largely due to a gradient zincophilic field that optimizes Zn transport and reduces side reactions, resulting in a more uniform and dense deposit on the Zn foil anode.
