Sustainable Production of Biofuels from Biomass Feedstocks Using Modified Montmorillonite Catalysts.

The rampant exploitation of fossil fuels has led to the significant energy scarcity and environmental disruption, affecting the sound momentum of development and progress of human civilization. To build a closed-loop anthropogenic carbon cycle, development of biofuels employing sustainable biomass feedstocks stands at the forefront of advancing carbon neutrality, yet its widespread adoption is mainly hampered by the high production costs. Montmorillonite, however, has garnered considerable attention serving as an efficient heterogeneous catalyst of ideal economic feasibility for biofuel production, primarily due to its affordability, accessibility, stability, and excellent plasticity.

Millet-based crop planting strategies in the Songhua River Region during the liaojin (907-1234 AD) dynasties: A case of the Luotong Mountain City site.

Introduction: Millet-based dryland agriculture is the traditional mode of agricultural cultivation in northern China and has been of great significance to the emergence and development of Chinese civilization. However, although they are both millet-based agricultural production methods, with various subtypes in different regions of northern China. In the Songhua River Region in northeast China, the ecological environment and abundant natural resources led to the slow development of agriculture, and it was only after the Liaojin Dynasties that a mature farming industry was formed.

Development and Validation of Near-Infrared Methods for the Quantitation of Caffeine, Epigallocatechin-3-gallate, and Moisture in Green Tea Production.

The quality of tea leaves (e.g., their color, appearance, and taste) can be directly influenced by the tea production process, which is closely connected with the content of a number of chemical components formed during the production of the tea leaves.

Chemically Edited Exosomes with Dual Ligand Purified by Microfluidic Device for Active Targeted Drug Delivery to Tumor Cells.

Exosomes, which are lipid membrane-bound nanovesicles (50-150 nm in diameter), have aroused extensive attention for their potential applications in invasive molecular and stand for a new therapeutic delivery system. However, they are limited by poor targeting ability and a lack of efficient isolation techniques. Here, we present a three-dimensional nanostructured microfluidic chip, in which arrays of micropillars were functionalized with crisscrossed multiwall carbon nanotubes by chemical deposition, to capture exosomes with high efficiency through a combination of a specific recognition molecule (CD63) and the unique topography of the nanomaterials.

Single Cell Chemical Proteomics with Membrane-Permeable Activity-Based Probe for Identification of Functional Proteins in Lysosome of Tumors.

Proteomics at single-cell resolution can help to identify the heterogeneity among cell populations, shows more and more significance in current chemistry and biology. In this work, we demonstrated a new single cell chemical proteomic (SCCP) strategy with a membrane-permeable activity-based probe (ABP) to characterize the functional proteins in lysosome located in the cytosol. The ABP targeted to the cysteine cathepsin family protein, CpFABP-G, was designed for cysteine cathepsins labeling.
