This disclosure provides a method for unsealing decompressed photovoltaic (PV) laminates, belonging to the field of PV module recycling technology. The method uses a solution comprising terpinene, isopropanol, and lauroyl sarcosine as the unsealing agent to disrupt the cross-linked network structure of EVA, causing EVA to lose its adhesiveness and releasing the EVA. This achieves complete separation of the backsheet, glass, and silicon layer in the decompressed PV laminate, facilitating the subsequent recycling of organic and metal resources from the backsheet. The entire process is green, efficient, and produces no secondary pollution. The unsealing agent can be recovered and recycled through distillation and condensation, resulting in significant economic benefits.

This invention relates to the field of agricultural pest repellency technology, specifically to a repellent for female potato tuber moths based on benzaldehyde or γ-terpinene and its application. This invention identified volatile compounds, benzaldehyde and γ-terpinene, from leaves of the Andean subspecies of potato, which have significant repellent effects on the potato tuber moth. Their repellent activity against adult female potato tuber moths was verified using an antennal potentiometer, a tetra-arm olfactory spectrometer, and an oviposition preference test. Experiments showed that benzaldehyde at doses of 10-100 μg and γ-terpinene at doses of 10-100 μg both had significant repellent effects on female potato tuber moths, effectively reducing their oviposition in the treated area. The benzaldehyde and γ-terpinene described in this invention are derived from plants, are environmentally friendly, and can be used to prepare repellents for female potato tuber moths, providing a new technical means for the green control of potato tuber moths, and have significant application value and promising prospects.

Terpinolene as a potentiator of the action of conventional antifungal drugs. The present invention describes a process for obtaining antifungal products for the control of dermatophytosis in humans and animals, composed of the natural product terpinolene and various combinations of terpinolene and terbinafine. Dermatophytosis is one of the most prevalent mycoses worldwide. Currently, a high rate of fungal resistance is reported, justifying the search for natural products that can act as new modulating agents of the action of conventional antifungals. Thus, the association of terpinolene with terbinafine can lead to a reduction in their effective concentrations for inhibiting fungal growth and treatment. Therefore, the present invention offers an innovative alternative of a natural product that exhibits antifungal activity in its isolated form and synergistic activity when associated with terbinafine at subinhibitory concentrations.
