Utilizing waste-derived carbon source for partial denitrification-anammox process: Wastewater- and sludge-derived organics.

The partial denitrification-anammox (PDA) process is a promising and sustainable technology for nitrogen removal in wastewater treatment. It is well-suited for mainstream nitrogen removal from municipal wastewater, polishing of anammox for ammonia-rich wastewater treatment, and simultaneous treatment of nitrate and ammonia containing wastewater. While the PDA process reduces external carbon source consumption by over 40 %, it still requires additional carbon input.

Microbial and functional resilience of a flocculent sludge-based partial denitrification-anammox system against cold temperature.

The anammox process offers low-carbon, cost-effective solution for municipal wastewater treatment but faces challenges in non-tropical regions due to temperature sensitivity. This study investigated the nitrogen removal performance, microbial dynamics, and functional gene responses of an integrated partial denitrification-anammox (PDA) system using flocculent sludge under gradual and sudden temperature declines. The PDA process maintained stable nitrogen removal under gradual cooling, with effluent total nitrogen (TN) <1.

Engineering tripartite gene editing machinery for highly efficient non-viral targeted genome integration.

Non-viral DNA donor templates are commonly used for targeted genomic integration via homologous recombination (HR), with efficiency improved by CRISPR/Cas9 technology. Circular single-stranded DNA (cssDNA) has been used as a genome engineering catalyst (GATALYST) for efficient and safe gene knock-in. Here, we introduce enGager, an enhanced GATALYST associated genome editor system that increases transgene integration efficiency by tethering cssDNA donors to nuclear-localized Cas9 fused with single-stranded DNA binding peptide motifs.

Preparation and Properties of Boron Modified Phenolic Resin for Automotive Friction Materials.

To address the thermal fade problem of brake pads, a boron-modified phenolic resin with better temperature resistance is intended to be developed. By introducing B-O bonds and high-temperature-resistant units, the thermal decomposition temperature of the phenolic resin will be increased. The modified resin is obtained through a step-growth polymerization reaction and then incorporated into the brake pad formulation to be hot-pressed into samples.

Protocol for the symmetry manipulation of gyroidal mesostructures through the binary self-assembly of block copolymer and cationic surfactant.

New symmetries of the gyroid (G) surfaces are the key to their intriguing properties. Here, we present a protocol to create a tetragonal gyroid substructure (shifted tG) outside the traditional cubic symmetry of G surfaces. We describe steps for employing a binary self-assembly system consisting of block copolymers and surfactants.

A New Bacterial Chassis for Enhanced Surface Display of Recombinant Proteins.

Introduction: Bacterial surface display is a valuable biotechnology technique for presenting proteins and molecules on the outer surface of bacterial cells. However, it has limitations, including potential toxicity to host bacteria and variability in display efficiency. To address these issues, we investigated the removal of abundant non-essential outer membrane proteins (OMPs) in as a new strategy to improve the surface display of recombinant proteins.

Non-pathogenic E. coli displaying decoy-resistant IL18 mutein boosts anti-tumor and CAR NK cell responses.

The tumor microenvironment can inhibit the efficacy of cancer therapies through mechanisms such as poor trafficking and exhaustion of immune cells.

Inserting colloidal quantum dots into GaN mesa-array subsurface porous structures through electrochemical etching for display color conversion application.

High-efficiency photon color conversion is an approach of great potential for implementing color display. Inspired by the observation of emission enhancement in a nanoscale cavity, a novel technique to fabricate an array of color converter by mixing colloidal quantum dots (QDs) with the electrolyte of an electrochemical etching (ECE) process is demonstrated. In this process, QDs flow with the electrolyte into the etched subsurface nanoscale porous structure (PS) and settle inside.

Controllable synthesis of porous boron nitride fibers modified by cobalt and nickel oxides for efficient ceftriaxone sodium adsorption from aqueous solution.

Antibiotics can easily enter the water environment through direct or indirect approach, causing environmental pollution and endangering the health of organisms. Therefore, development of highly efficient adsorbent materials to adsorb and remove antibiotics is necessary. Here, cobalt oxide and nickel oxide are uniformly and tightly bonded on the surface of porous boron nitride fibers (PBNFs-NiCo), increasing the number of functional groups (B-O and N-H) and hydrogen bond receptors within PBNFs.

Carbon and nitrogen addition-derived enzyme activities in topsoil but nitrogen availability in subsoil controls the response of soil organic carbon decomposition to warming.

Subsoil stores the majority of soil organic carbon (SOC), and plays a vital role in the global carbon cycle in terrestrial ecosystems and in regulating climate change. Response of SOC decomposition to temperature warming (TR) is a crucial parameter to predict SOC dynamics under global warming. However, it remains unknown how TR varies across the whole soil profile and responds to exogenous C and N inputs.

Pressureless Welding of Temperature-Invariant Multifunctionality Body Based on Hydroxyl-Functionalized Boron Nitride Nanosheets and Bifunctional Monoethanolamine Cross-linker.

Bulk hexagonal boron nitride (h-BN) ceramics with structural integrity, high-temperature resistance and low expansion rate are expected for multifunctional applications in extreme conditions. However, due to its sluggish self-diffusion and intrinsic inertness, it remains a great challenge to overcome high-energy barrier for h-BN powder sintering. Herein, a cross-linking and pressureless-welding strategy is reported to produce bulk boron nitride nanosheets (BNNSs) ceramics with well-crystalized and dense B-N covalent-welding frameworks.
