Endoglucanase is one of the most important enzymes of the cellulase group. Endoglucanase are involved in the catalytic hydrolysis of cellulose and plays a pivotal role in different sectors like pharmaceutical, textile, detergent, and food processing as well as paper and pulp industry. With consumers getting more and more aware of environmental issues, industries find enzymes as a better option over other chemical catalysts. In the current research different thermophilic fungal strains were isolated from the different sources. Qualitative screening was carried out on the basis of cellulose hydrolysis zone. The quantitative screening was carried out employing solid state fermentation. The fungal culture, showing highest EG potential was selected identified and assigned the code Aspergillus fumigatus BBT2. Different fermentation media were evaluated and M 2 containing wheat bran gave maximum EG production. The maximal enzyme productivity was recorded in 72 hours, 40°C, pH 5, inoculum size 1.5ml, and moisture content (1:1). Glucose (1%) and peptone (1%) were optimized as best carbon and nitrogen sources, respectively.

Laboratory-scale spin-coating techniques are widely employed for fabricating small-size, high-efficiency perovskite solar cells. However, achieving large-area, high-uniformity perovskite films and thus high-efficiency solar cell devices remain challenging due to the complex fluid dynamics and drying behaviors of perovskite precursor solutions during large-area fabrication processes. In this work, a high-quality, pinhole-free, large-area FAPbI perovskite film is successfully obtained via scalable blade-coating technology, assisted by a novel bidirectional Marangoni convection strategy.

The physical microenvironment plays a crucial role in tumor development, progression, metastasis and treatment. Recently, we proposed four physical hallmarks of cancer, with distinct origins and consequences, to characterize abnormalities in the physical tumor microenvironment: (1) elevated compressive-tensile solid stresses, (2) elevated interstitial fluid pressure and the resulting interstitial fluid flow, (3) altered material properties (for example, increased tissue stiffness) and (4) altered physical micro-architecture. As this emerging field of physical oncology is being advanced by tumor biologists, cell and developmental biologists, engineers, physicists and oncologists, there is a critical need for model systems and measurement tools to mechanistically probe these physical hallmarks.

A successful therapeutic outcome in the treatment of solid tumours requires efficient intratumoural drug accumulation and retention. Here we demonstrate that zinc gluconate in oral supplements assembles with plasma proteins to form ZnO nanoparticles that selectively accumulate into papillary Caki-2 renal tumours and promote the recruitment of dendritic cells and cytotoxic CD8 T cells to tumour tissues. Renal tumour targeting is mediated by the preferential binding of zinc ions to metallothionein-1X proteins, which are constitutively overexpressed in Caki-2 renal tumour cells.

Research on pancreatic cancer has transformed with the advent of organoid technology, providing a better platform that closely mimics cancer biology in vivo. This review highlights the critical advancements facilitated by pancreatic organoid models in understanding disease progression, evaluating therapeutic responses, and identifying biomarkers. These three-dimensional cultures enable the proper recapitulation of the cellular architecture and genetic makeup of the original tumors, providing insights into the complex molecular and cellular dynamics at various stages of pancreatic ductal adenocarcinoma (PDAC).

With promises for high specific energy, high safety and low cost, the all-solid-state lithium-sulfur battery (ASSLSB) is ideal for next-generation energy storage. However, the poor rate performance and short cycle life caused by the sluggish solid-solid sulfur redox reaction (SSSRR) at the three-phase boundaries remain to be solved. Here we demonstrate a fast SSSRR enabled by lithium thioborophosphate iodide (LBPSI) glass-phase solid electrolytes (GSEs).
