Boric acid dust treatments were evaluated as a tool for the integrated management of the German cockroach, Blattella germanica (L.), in commercial confined swine production. The efficacy of boric acid dust was comparable to that of an organic residual insecticide, cyfluthrin, which is commonly used to control cockroaches in this environment. Fall treatments suppressed the cockroach population for longer durations than treatments in the Spring. Boric acid dust is an effective, inexpensive, and low risk (to animal and human health, and the environment) alternative for the management of cockroaches in livestock production systems.

Long lifetime multicolor phosphorescence materials possess excellent optical properties and have important application prospects in the fields of advanced anti-counterfeiting and information encryption. However, realizing long lifetime and color-tunable room temperature phosphorescent (RTP) carbon dot (CD) materials has proved challenging. In this study, the organic precursor molecules 2-phenethylamine (2-Ph), 9-aminophenanthrene (9-Ph) and 1-aminopyrene (1-Py) with different degrees of conjugation were selected to synthesize RTP CD composites: 2-Ph@BA, 9-Ph@BA and 1-Py@BA were synthesized by mixing with a boric acid (BA) matrix under high temperature pyrolysis.

In contemporary times, the waning effectiveness of antibiotics against bacterial infections is progressively giving rise to significant concerns in public health. Although photodynamic technology possesses a potent ability to deactivate bacteria, its non-selective attack on normal cells poses potential side effects. Hence, in this study, a boric acid-substituted phthalocyanine photosensitizer (BAPc) was synthesized, exhibiting remarkable bacterial targeting capability.

Background/objectives: rapidly acquires antibiotic resistance and demonstrates increasing tolerance to antiseptics. This study evaluated the activity of eight antiseptics against , assessed its ability to develop adaptation to these antiseptics, and, for the first time, determined the Karpinski Adaptation Index (KAI) for this bacterium.
Methods: The minimal inhibitory concentration (MIC), susceptibility to antibiotics, bactericidal time according to EN 1040:2005, adaptation potential, and KAI of strains were evaluated.

The aim of this project is to fabricate fiber mats and hydrogel materials that constitute the two main components of a wound dressing material. The contributions of boric acid (BA) and zinc oxide (ZnO) to the physical and mechanical properties of polycaprolactone (PCL) is investigated. These materials are chosen for their antimicrobial and antifungal effects.

In clinical boron neutron capture therapy (BNCT), the distribution of dose to a heterogeneous medium that is predicted by a treatment planning system (TPS) should be experimentally validated. A head phantom specifically developed for this purpose is described and demonstrated herein. The cylindrical phantom exhibits distinct regions made from four materials (polymethyl methacrylate, calcium phosphate, air, and boric acid) to approximate a head structure with explicitly defined skin, skull, and brain tissue with a cavity and tumor within.
